US Exposes Major Chinese Cyber-Espionage Targeting Telecom Networks

 


The United States has accused China of conducting a vast cyber espionage operation that targeted multiple telecommunications networks. The hackers allegedly stole sensitive data and intercepted communications relating to a few government and political leaders. The incident raises national security concerns, in which officials are sounding warning bells.

US officials said that Chinese state-sponsored hackers broke into the systems of several telecom companies, looking to syphon away customer call records and gain unauthorised access to communication data. In some cases, the attackers allegedly copied information sought by US law enforcement through court-approved procedures, said analysts. That's a disturbing breach of sensitive data.

This is receiving full-time investigation by the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) to help targeted companies. Officials said they are only slowly learning the extent of what happened, but preliminary reports indicate a sophisticated attack that probably reaches virtually everywhere in the country.


 

Key Targets and Methods


Unnamed sources suggest that major telecom providers, including AT&T and Verizon, were among those breached. Hackers allegedly found a way into systems used for court-authorised wiretaps, bypassing security measures. Microsoft identified the group responsible as “Salt Typhoon,” a hacking collective linked to the Chinese state.


According to reports, this group had been undetected for months before exploiting vulnerabilities to gain access to sensitive communication networks. The list of allegedly targeted big fish includes former President Donald Trump, members of his family, and Vice President Kamala Harris' campaign staff. 


Impact Beyond Large Companies

The scope of the attack does not only extend to big corporations. Regional internet service providers were also targeted, which shows how the hackers covered many areas. Experts think that the attackers must have abused the wiretap systems by monitoring some specific numbers, which may give them audio data through such breaches.

 

Wider Issues and Follow-Up Investigations

US authorities have already informed dozens of affected organisations. Classified briefings have lately been conducted to enlighten lawmakers on the serious implications. Senator Ron Wyden, who attended one of the briefings described the breach as deeply concerning in regard to its implications across various sectors.

While the probe is still ongoing, more efforts have been committed toward discovering the scope of the operation. According to a State Department official, this attack highlighted vulnerabilities in telecom systems believed to have been secure, and a greater need for upgraded cyber defence mechanisms is therefore urgent.

This incident typifies the dynamic threat of state-sponsored cyberattacks with regard to challenges in safeguarding critical infrastructure. The US is to enhance its defence mechanisms and systems for better preparedness to such breaches in the future as investigations continue.

New TSA Rules to Boost Cybersecurity in Transport






The Transportation Security Administration recently unveiled a proposed rule that would permanently codify cybersecurity reporting requirements in certain segments of U.S. transportation, including pipelines and railroads. This change is set to be permanent after the agency introduced temporary reporting requirements for certain segments last year after a ransomware attack hit Colonial Pipeline, causing fuel shortages along the U.S. East Coast.


Locked In Securely

Since the Colonial Pipeline incident, the Transportation Security Administration has issued a number of temporary rules regarding cybersecurity risks in critical infrastructure. The new proposed rule would bring these temporary rules into permanence and codify a consistent approach throughout transportation on cybersecurity matters. As Administrator Pekoske pointed out, "TSA has been working extremely closely with industry partners to assist in enhancing the cybersecurity resilience of our nation's critical infrastructure."


Key Components of the Proposed Rule

This new law applies to a large scope of pipeline and railroad operators and places restrictions only on some bus companies. Its main emphasis is put on the implementation of cyber risk management plans that shall encompass:

  • Annual Cybersecurity Reviews: These reviews will require assessments and improvements in cyber defences.
  • Vulnerability Assessments: Conduct vulnerability assessments of security weaknesses that have not been remediated. Such assessments shall be conducted either by the covered entity's own personnel or a third party, but such personnel shall have no conflict of interest with respect to the covered entity.
  • Operational Cybersecurity Plans: They would describe the functions of personnel in a cybersecurity company, what is in place to protect critical systems, and procedures in identifying a threat to and responding to it.

Under these proposed regulations, operators would have to report cybersecurity incidents to the Cybersecurity and Infrastructure Security Agency (CISA) to receive faster response to and support of a threat.


Impact and Cost

The TSA estimated that the rulemaking would affect about 300 transportation operators-from pipelines, freight railroads, to public transportation agencies. These include 73 freight railroads, 34 public transportation systems, 71 over-the-road bus companies, and 115 pipeline facilities. Compliance and TSA oversight are estimated to cost the industry $2.1 billion over the next ten years.

The TSA attributed the regulations to the emerging threats of cyber attacks posed by nation-state actors and cybercriminals, who often target U.S. infrastructure in efforts to disrupt it and further inflict economic damage. Countries, according to the TSA, "such as Russia and China" were cited as frequent sources of cyberattacks on American critical infrastructure.

The agency's proposal underlines the need for uniform cybersecurity measures to be taken as soon as possible as cyber threats are becoming more advanced: they are now set to use artificial intelligence to deliver faster, undetectable attacks.


Industry Reaction and Flexibility

The proposal takes place on the grounds that the earlier directions were considered too elaborative by the transporters who had imparted them. The TSA will be more agile and results-driven now, allowing the companies to engage themselves in security solutions pertaining to the specific needs of each one.

The proposed rule will be open to comments from the industry until February 5 while reviewing all the responses the TSA will have before finalising the rule. The agency looks forward to providing enhanced cybersecurity and resilience within U.S. surface transportation systems by defeating the increasing cyber threats.

AI developers CISA Cyber Security data security Encryption Executive Order 14117 government data National Security U.S. personal data Vulnerability

CISA Proposes New Security Measures to Protect U.S. Personal and Government Data

 

The U.S. Cybersecurity & Infrastructure Security Agency (CISA) has proposed a series of stringent security requirements to safeguard American personal data and sensitive government information from potential adversarial states. The initiative aims to prevent foreign entities from exploiting data vulnerabilities and potentially compromising national security.

These new security protocols target organizations involved in restricted transactions that handle large volumes of U.S. sensitive personal data or government-related data, especially when such information could be exposed to "countries of concern" or "covered persons." This proposal is part of the broader implementation of Executive Order 14117, signed by President Biden earlier this year, which seeks to address critical data security risks that could pose threats to national security.

The scope of affected organizations is wide, including technology companies such as AI developers, cloud service providers, telecommunications firms, health and biotech organizations, financial institutions, and defense contractors. These businesses are expected to comply with the new security measures to prevent unauthorized access to sensitive information.

"CISA’s security requirements are split into two main categories: organizational/system-level requirements and data-level requirements," stated the agency. Below is a breakdown of some of the proposed measures:

  • Monthly Asset Inventory: Organizations must maintain and update a comprehensive asset inventory that includes IP addresses and hardware MAC addresses.
  • Vulnerability Remediation: Known exploited vulnerabilities should be addressed within 14 days, while critical vulnerabilities, regardless of known exploitation, must be remediated within 15 days. High-severity vulnerabilities should be resolved within 30 days.
  • Accurate Network Topology: Companies must maintain a precise network topology, which is crucial for identifying and responding to security incidents swiftly.
  • Multi-Factor Authentication (MFA): All critical systems must enforce MFA, and passwords must be at least 16 characters long. Immediate access revocation is required upon employee termination or a change in roles.
  • Unauthorized Hardware Control: Organizations must ensure that unauthorized hardware, such as USB devices, cannot be connected to systems handling sensitive data.
  • Log Collection: Logs of access and security-related events, including intrusion detection/prevention, firewall activity, data loss prevention, VPN usage, and login events, must be systematically collected.
  • Data Reduction and Masking: To prevent unauthorized access, organizations should reduce the volume of data collected or mask it, and encrypt data during restricted transactions.
  • Encryption Key Security: Encryption keys must not be stored alongside the encrypted data, nor in any country of concern.
  • Advanced Privacy Techniques: The use of techniques like homomorphic encryption or differential privacy is encouraged to ensure sensitive data cannot be reconstructed from processed data.
CISA has called for public feedback on the proposed security measures before they are finalized. Interested parties can submit their comments by visiting regulations.gov, entering CISA-2024-0029 in the search bar, and submitting feedback through the available form.

APT Group CISA Cyber Security Hacking Middle East OilRig Ransomware

New Cybersecurity Threat for the Middle Eastern Countries: OilRig Malware

 



Cybersecurity experts say that there is a new threat against Middle East organisations, and more specifically within the United Arab Emirates, and other Gulf countries. There is an Iranian gang cybercrime known as OilRig that aims to hunt login credentials for access into several organisations and personal systems, with a focus on infiltration of key infrastructures within the region.


Role of OilRig in Attacks

OilRig is another notorious state-sponsored hacking group. At other times, it was known by the designations APT43 and Cobalt Gipsy. Its origins date back to Iranian government sponsorship. And in previous campaigns, OilRig has mainly focused on exploiting exposed servers with web shells - a category of malicious software. This gives attackers the ability to take control of an affected server remotely and run PowerShell scripts from it. As such, such a gain in access allows it to facilitate attackers in finding deeper access into the system.

Once the group fully takes over the system, they exploit the flaw CVE-2024-30088. Microsoft discovered that it had patched this security vulnerability in June 2024 for the Windows operating system. This allows the attackers to elevate their privilege, which gives attackers access to the forbidden areas of the system, thus limiting their operations. According to Microsoft, this is a high-risk vulnerability with a base score of 7.0.


How the Malware Works

This attack utilises a malware referred to as STEEL HOOK, that is a very sophisticated piece of malware. STEALHOOK gathers sensitive information from the infected systems. It tumbles the gathered data with other legitimate data that would aid in its undetected operation. Then, it sends it back to the attackers using an Exchange server. This exfiltrated the data, keeping it hidden from cybersecurity defences. Since it moves as traffic, the attackers subtly can extract sensitive information without immediately causing an alarm.


Ties to Ransomware and Other APT Groups

OilRig's operations closely relate to another Iranian threat group known as FOX Kitten, which is particularly infamous for ransomware campaigns. These connections suggest a broader strategy by Iranian hacking groups in targeting and disrupting key industries, with a specific focus on the energy sector. According to Trend Micro, most of OilRig's targets fall in the energy sector; disruption in such industries could have ripple effects at regional and global levels. This sector is also important, and any extended interference could seriously affect daily life because energy supply lines take such a large part of this region's infrastructure.


Vulnerability Not Yet Flagged By CISA

Shockingly though there is a belief that this flaw is already being exploited, the United States Cybersecurity and Infrastructure Security Agency (CISA) has yet to include CVE-2024-30088 in the Known Exploited Vulnerabilities catalogue. Therefore, for organisations to decide and focus on patching the exploited vulnerabilities used by hackers, this catalogue becomes highly important. Its absence on the list means that there still exists an increased need for a general awareness of the threat and hence affected organisations need to patch up their systems actively.

Among the many malware campaigns that have lately been in view targeting the Middle East, OilRig seemed to reflect the rising complexity and frequency of cyber attacks. In fact, energy sector organisations need to be highly aware of such sophisticated attacks. Ultimately, the case of exploitation involving CVE-2024-30088 would reflect critical and constant risks given by state-sponsored cyber criminals. Meanwhile, it emphasises the advisability of timely software updates and the need for strong cybersecurity measures against unauthorised access and data theft.

In that respect, there is a call for protection of the information systems companies have from these advanced threats from corporate and individual entities. In this respect, OilRig can be prevented through great proactive steps and awareness in preventing these powerful cyberattacks from taking their worse course of follow-up actions.

APT-29 CISA Cookies Cozy Bear Cyber Security

How F5 BIG-IP Cookies Are Being Exploited for Network Snooping: A CISA Warning

 



US Government's Cybersecurity and Infrastructure Security Agency released a warning regarding cyberattackers use of unencrypted cookies managed by the F5 BIG-IP Local Traffic Manager, by which they gather information about private networks. In this manner, these attackers identify the internal, non-public devices through the use of this cookie, thereby potentially targeting the vulnerabilities on that network. While CISA does not disclose who is behind this attack and for what reasons, the activity surely indicates serious threat potential to organisational security.

Confidence and Data Integrity Exposed

According to CISA's advisory, these cookies would probably allow attackers to understand the network structures and discover some areas where the attack can be performed. It is true that cybersecurity has compared with physical security, some delicate balances of trust on which companies dealing with sensitive information depend. The attackers may go through the data contained in these cookies while studying it and realise and use key resources in a network to escalate access or tamper with data.

Recommendations for the Protection of F5 BIG-IP Cookies

CISA recommends that all the organisations that use the F5 BIG-IP equipment encrypt those cookies. The encryption can be set up on these devices through HTTP profile settings so it can act as an added layer of protection against unauthorised access. CISA further recommends use of the BIG-IP iHealth diagnostic tool by F5, which conducts full system evaluation against potential weaknesses and vulnerabilities. The tool offers tailored recommendations for bettering security circumstances, including configuration issues or outdated code.

Warnings of Broader Cyber Threats

The U.S. and the U.K. cybersecurity agencies have simultaneously warned about the Russian-backed hacking group APT29, which is also known as Cozy Bear or Midnight Blizzard. This group has consistently targeted areas in the areas of diplomatic, defence, tech, and financial sectors to obtain sensitive foreign intelligence. APT29, which links back to Russia's Foreign Intelligence Service (SVR), practises low-key in conducting operations and utilises TOR and other tools of similar nature to mask its operations.

APT29: Tactics of Persistence, Stealth, Strategy

APT29's infrastructure is complicated, and the actors often lease servers through fake identities and low-reputation email addresses in North America. This makes detecting the activity in the network more challenging because it imitates legitimate network traffic. In addition to intelligence gathering, APT29 often tries to create enduring access within targeted systems through spear-phishing or exploiting widely known, but unpitched, vulnerabilities. Other notable vulnerabilities of interest recently include CVE-2022-27924 in Zimbra Collaboration and CVE-2023-42793, a TeamCity Server authentication bypass flaw that could help facilitate remote code execution.

Defending Against APT29 Threats

APT29 is famous for changing its tactics to evade detection and will destroy its infrastructure if it detects that it is under surveillance. To mitigate this, organisations are encouraged to implement and track baseline network activity, which makes it easier to recognize aberrant access patterns. The hackers' strategies include proxy networks and mobile and residential IP addresses to mirror legitimate users. Thus, companies should look at access attempts with a magnifying glass to identify deviations from normal behaviour.

Importance of Regular Security Patches

Tenable, a cybersecurity firm, claims that the only way to win against APT29 and other advanced persistent threats (APTs) is by having recent versions of the software. The main way of countering such attacks is by keeping security updates and patches on known vulnerabilities. Tenable Senior Research Engineer Satnam Narang said that the long-term targeting of organisations operating within the U.S. and Europe by APT29 underlines its foreign intelligence gathering and ensures long-term access to compromised systems.

It is a necessity both for the advisory put out by CISA and the joint bulletin by the U.S. and U.K. in light of the evolution of these threats. For organisations, keeping sensitive information safe and establishing trust becomes of utmost importance. The use of security measures like encrypting F5 BIG-IP cookies and keeping updated on threat intelligence can stop attackers from exploiting their weaknesses. Proactive defences have to be built up in these systems because they are becoming increasingly complex in nature and ensuring the integrity of data and avoiding malicious intrusion into it.

CISA Cyber Security Kansas United States Water System

Kansas Water Plant Switches to Manual Operations Following Cyberassault

 

The top cybersecurity agency in the United States has released a new advisory, stating that nation-states and cybercriminals remain a threat to government-run water systems. 

The Cybersecurity and Infrastructure Security Agency (CISA) issued the notification two days after Arkansas City, Kansas, reported a cybersecurity vulnerability that required it to switch to manual operations. 

On Thursday, CISA stated that it will "respond to active exploitation of internet-accessible operational technology (OT) and industrial control systems (ICS) devices, including those in the Water and Wastewater Systems (WWS) Sector.” “Exposed and vulnerable OT/ICS systems may allow cyber threat actors to use default credentials, conduct brute force attacks, or use other unsophisticated methods to access these devices and cause harm.” 

The cyber agency recommended operators to use previously released advice to secure systems. The attack on Arkansas City, which is home to approximately 11,000 people, began on Sunday morning. City Manager Randy Frazer declined to comment on whether the FBI and CISA were involved in the reaction to the attack, but stated that the water system remains completely safe and there has been no disruption in service.

Due to their significance, the more than 150,000 public water systems in the United States have been a focal point of dispute about the role of federal and state governments in cybersecurity protection. 

Despite a significant increase in the frequency of ransomware assaults and nation-state intrusions, water industry associations teamed up with Republican senators last year to halt federal measures to protect drinking water infrastructure.

Even after a series of attacks on U.S. water facilities last autumn by hackers apparently linked to the Iranian government, groups such as the American Water Works Association have claimed that they should be entitled to create their own cybersecurity regulations for the industry. 

Several cybersecurity specialists have reported an increase in assaults on industrial water systems, and they agree with CISA that one of the primary challenges is that numerous water systems continue to link industrial tools to the internet in order to remotely manage them. 

Waterfall Security Solutions CEO Lior Frenkel told Recorded Future News that in his extensive work with water system operators, many either don't know what tools are connected to the internet or believe the risks outweigh the advantages. 

“Systems that are connected to the internet can be shut down or manipulated or can impair the process that they are controlling,” Frenkel stated. “All of that should never be accessible from the internet unless there's such a need that you can say that need is stronger than the risk. But the default today is they are connected. We try to put them off the grid. The default should be everything is off the grid, and you connect only what's the bare necessity.”

Rhysida Ransomware Hits Seattle Port in August Attack

 


As part of its investigation, the Port of Seattle, which operates Seattle-Tacoma International Airport in the city, has determined that the Rhysida ransomware gang is responsible for the cyberattack that allowed it to reach its systems last month, causing travel delays for travellers. There has been a ransomware attack targeting the Port of Seattle as early as Friday, the Port announced in a statement. 

As a result of the attack, which happened on August 24, the Port (which is also responsible for operating Seattle-Tacoma International Airport) announced that "certain system outages have indicated a possibility of a cyberattack." It is important to note that the SEA Airport and its associated facilities remained open after the storm, but passenger displays, Wi-Fi, check-in kiosks, ticketing, baggage, and reserved parking were impacted, as well as the flySEA application and the Port website.

According to a press release that was released on September 13, the Port reported that most of the affected systems had been restored within a week of the attack taking place. As of yet, the Port of Dusseldorf has not been able to relaunch the external website or the internal portals that were offline after securing the impacted systems and finding no signs of additional malicious activity. 

As far as Port systems were concerned, this incident was a "ransomware" attack by Rhysida, a criminal organization that specializes in cybercrime. Since that day, no new unauthorized activity has been conducted on those systems. In a press release, they stressed that it was safe to fly to Seattle-Tacoma International Airport and use the port's maritime facilities. 

During this time, the Port's decision to take systems offline was accompanied by the ransomware gang's encryption of the ones that were not isolated in time, resulting in a series of outages impacting a variety of services and systems, including baggage, check-in kiosks, ticketing, wireless Internet, passenger display boards, the Port of Seattle website, flySEA app, and reservations. 

A ransomware attack believed to have been launched by the Rhysida hacker group can be blamed for encrypting some of the data on the Port's computer systems using the ransomware. It was the result of this encryption and the Port's response to isolate the impacted systems as soon as possible that there were delays at the Sea-Tac Airport with baggage services, check-in kiosks, ticketing, Wi-Fi, displays, the Port's website and the flySEA app having issues. 

The majority of these issues have since been resolved; however, the airport's website and internal portals remain down as of this writing, as stated in an update posted by the Port of Los Angeles. In the wake of the cyber attack at the airport, the Port of Los Angeles is still unsure exactly how much or what kind of data was taken by the attackers, but the Port cannot afford to pay the ransom demand. There are no details about what kind of data have been compromised in the attack; however, the data may likely be of great value due to the sector of the business in which the agency operates. 

There is also another reason that the Port of Seattle is such a hotbed of automation and machine learning technologies, which means it's a goldmine for attackers in terms of data. In the world of ransomware, Rhysida is one of the more well-known gangs, especially for the way they target organizations that run critical systems for which downtime is not an option. 

A hacker group known as the Black Hat Network has in the past targeted healthcare organizations such as the Lurie Children's Hospital and Prospect Medical Holdings as targets. As of May 2024, the number of patients affected by this massive data breach had increased from a few hundred to nearly a million. The company claimed that the Singing River ransomware attack occurred in September 2023.

In addition to educational institutions and the manufacturing industry, the HHS Health Sector Cybersecurity Coordination Center has also reported that the group has targeted the Chilean army, as well as universities and hospitals, according to the report. Health and Human Services (HHS) in the United States has implicated Rhysida in an attack against healthcare organizations in the country. 

As CISA and the FBI made their warnings at the same time, different industries and sectors of society were being targeted by opportunistic attacks by this cybercrime gang at the same time. In November, Rhysida ransomware operators successfully breached Insomniac Games, a subsidiary of Sony, and subsequently leaked 1.67 TB of confidential documents on the dark web. This occurred after the game development studio declined to meet the group’s demand for a $2 million ransom. 

Rhysida's affiliates have also been involved in attacks on several other high-profile organizations. The City of Columbus, Ohio, MarineMax (the world's largest retailer of recreational boats and yachts), and the Singing River Health System have all fallen victim to this ransomware group. In particular, Singing River Health System reported that almost 900,000 individuals were notified of a data breach resulting from an August 2023 ransomware attack, in which sensitive personal information was compromised.

CISA Identifies Industrial Cybersecurity Bugs in Baxter and Mitsubishi Products

 


A report published recently by the Cybersecurity and Infrastructure Security Agency (CISA) warned about two new ICS vulnerabilities found in products widely used in healthcare, critical manufacturing, and other sectors susceptible to cybercrime activity. Among the affected products are Baxter's Connex Health Portal, as well as Mitsubishi Electric's MELSEC line of programmable controllers for the home and office. 

In response to the vulnerabilities found in the respective technologies, both vendors have released updates to plug the vulnerabilities and recommended mitigations for customers who wish to mitigate risk further. According to CISA's advisory, two vulnerabilities were identified in Baxter's Connex Health Portal (formerly Hillrom and Welch Allyn) that could be remotely exploited and have low attack complexity, which made them suitable for remote attacks. 

The CVE-2024-6795 vulnerability is one of the highest severity (CVSS score of 10.0) SQL injection vulnerabilities that an unauthenticated attacker could exploit to run arbitrary SQL queries on affected systems through one of the vulnerabilities, assignment CVE-2024-6795. It was described by CISA that this vulnerability would allow attackers to view, manipulate, and delete sensitive data, in addition to taking other administrator-level actions, including shutting down the database in some cases. As part of the U.S. 

Cybersecurity and Infrastructure Security Agency (CISA) various advisory letters regarding industrial control systems (ICS) have been released, including one specifically for medical devices as well as two updates. As part of the project, we are developing advisories that serve to provide ICS owners with timely information about security threats, vulnerabilities, and exploits. It had previously been announced that the cybersecurity agency was deploying advisories across critical infrastructure sectors to warn users and technical administrators about ICS vulnerabilities and offer mitigation strategies. 

Hughes Network Systems has identified hardware vulnerabilities in its WL3000 Fusion software equipment that are caused by bugs in the hardware. This report contains updated information on vulnerabilities in Mitsubishi Electric's MELSEC iQ-R, Q, and L Series, as well as the MELSEC iQ-R, iQ-L Series, and the MELIPC Series, which are all produced by Mitsubishi Electric. During the CISA study, the vulnerability in the hardware architecture of the Baxter Connex Health Portal was also identified. 

CISA warned it in an advisory that Hughes' WL3000 Fusion Software deployed across critical infrastructure sectors appears to have several vulnerabilities that are not sufficiently protected such as credentials that are insufficiently protected and sensitive data that are not encrypted. The report states that if these vulnerabilities are exploited successfully, an attacker could gain access read-only to information associated with network configurations and terminal configurations, and otherwise gain access to confidential data. 

It is important to note that credentials for gaining access to device configuration information are stored in flash memory unencrypted. It is also possible with these credentials, to gain read-only access to information about the network configuration and terminal configuration. It has been assigned the designation CVE-2024-39278 as the vulnerability that needs to be addressed. The CVSS v3.1 base score was determined to be 4.2 out of a possible five points, and the CVSS v4 base score was calculated to be 5.1. 

A report by CISA also revealed that credentials for accessing device configurations were being transmitted using an unencrypted protocol that was not secure. These credentials would allow the administrator to access only the data associated with the configuration of the network and the terminals. The vulnerability has been identified as CVE-2024-42495 and it has been assigned a severity of critical. The CVSS v3.1 base score has been determined to be 6.5, and the CVSS v4 base score has also been calculated to be 7.1, based on the CVSS v3.1 and CVSS v4 scores. 

During publishing this advisory, Hughes Networks pointed out that the vulnerabilities had been corrected, which did not require any user action.  There is a risk of remote attackers, unauthenticated and remotely situated, running arbitrary SQL queries anywhere, at any time, including accessing, changing, and deleting sensitive data, as well as performing administrative operations on the database such as halting it. 

Two vulnerabilities in this system are associated with one CVE-2024-6795, and a CVSS v3.1 base score of 10.0 has been calculated for this vulnerability. A CISA report also indicated that the system was not appropriately protecting against an improper access control vulnerability in the application. As a result, an unauthorized user could have access to clinical and sensitive information about patients, as well as be able to change or delete information about the clinic. 

There has been a vulnerability identified as CVE-2024-6796 and it has been assigned a CVSS v3.1 base score of 8.2, which makes it a high vulnerability. As revealed by the advisory, Baxter is unaware of any exploits of these vulnerabilities or any compromises of personally identifiable information or health information related to this vulnerability. The Cybersecurity and Infrastructure Security Agency (CISA) has identified and flagged vulnerabilities in industrial control systems (ICS) used in products from Baxter and Mitsubishi. 

These vulnerabilities, which posed potential cybersecurity risks, were promptly addressed by both companies. Following their discovery, Baxter implemented the necessary patches to rectify the issues. As a result, no further action is required from users at this time. In addition to these remedial actions, CISA has issued general recommendations to mitigate future risks. One of the key suggestions is to minimize network exposure for all control system devices and systems, ensuring that they are not directly accessible from the internet. 

CISA further advises that control system networks and remote devices should be placed behind firewalls and segregated from business networks to enhance security. For instances where remote access is necessary, organizations are encouraged to adopt more secure solutions such as Virtual Private Networks (VPNs). However, CISA stresses the importance of maintaining up-to-date versions of VPN software, as vulnerabilities may exist in older versions. 

It is also emphasized that the overall security of the VPN is dependent on the security of the devices it connects to, underscoring the need for comprehensive security measures across all connected devices. By following these defensive measures, organizations can reduce the likelihood of exploitation and enhance the security of their industrial control systems against potential cyber threats.

CISA Launches Major Effort to Secure the 2024 U.S. Elections

 

The Cybersecurity and Infrastructure Security Agency (CISA) in the United States has initiated a comprehensive campaign to secure the 2024 elections. This effort involves deploying specialized advisory teams across the nation and coordinating security exercises with federal, state, and local officials, as well as with private sector partners. Cait Conley, a senior adviser at CISA, emphasized that securing the elections is a priority that involves the entire agency. 

In preparation for the 2024 national elections, CISA created election security adviser positions within its ten regional offices in July 2023 to offer frontline support to local election officials. These advisers are now fully in place and work closely with state election offices to provide guidance and assistance. The agency recently organized a four-day workshop, “Tabletop the Vote,” to enhance readiness against both cyber and physical threats. Conley noted that CISA is investing more resources than ever before to safeguard election infrastructure. 

This builds on the agency’s past successes in securing the 2016 and 2020 elections, which saw the implementation of advanced threat detection and response measures that thwarted interference attempts by foreign adversaries, including Russia. CISA is also preparing for new threats. Recently, the agency warned of increased cyber activity from Iran aimed at disrupting the upcoming election cycle. The Department of Homeland Security has classified election infrastructure as critical to national security, underscoring the importance of protecting voter registration databases, information technology systems, polling places, and voting machines. 

To support this mission, CISA has introduced several tools and resources designed to enhance election security. These include a comprehensive cybersecurity toolkit through the Joint Cyber Defense Collaborative and a “Rumor vs. Reality” platform to counter disinformation about elections. Over the past several years, the agency has also rolled out free services like vulnerability scanning and physical security assessments to minimize risks to election systems. 

CISA Director Jen Easterly highlighted the significant improvements in the agency’s capabilities compared to 2016. As the 2024 elections approach, CISA remains committed to deploying its resources and strengthening partnerships to protect the democratic process from evolving threats. The agency’s continued efforts aim to ensure that election infrastructure remains secure against any potential interference.

Chinese Hackers Exploit Serious Flaw in Versa SD-WAN Systems


 

A Chinese cyber-espionage group, known as Volt Typhoon, has been exploiting a newly discovered security flaw in Versa Networks' SD-WAN Director servers. This zero-day vulnerability, identified as CVE-2024-39717, has already been used to infiltrate several organizations. Given the seriousness of this issue, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has listed it among known exploited vulnerabilities, urging immediate corrective actions.

The CVE-2024-39717 vulnerability impacts all versions of Versa Director released before version 22.1.4. The issue originates from a feature in the system's graphical user interface (GUI) that allows for customisation. Versa Director is a crucial part of Versa Networks' software-defined wide area networking (SD-WAN) solutions, which are used by ISPs, MSPs, and large corporations to manage network devices, route traffic, and enforce security policies. Unfortunately, this vulnerability enables attackers to steal user credentials, potentially leading to further attacks.

Dan Maier, Versa's Chief Marketing Officer, noted that this flaw could allow attackers to escalate privileges without authorization. Attackers can initially access Versa Director through high-availability management ports 4566 and 4570, particularly if these ports are left open to the internet. Once inside, they can gain administrator-level credentials, giving them complete control over the system. Maier emphasised that Versa has long advised customers to limit access to these critical ports to prevent such security breaches.

The vulnerability was first discovered by researchers at Lumen Technologies' Black Lotus Labs. They found that Volt Typhoon had been exploiting this flaw since at least June 2024. The attackers used small office/home office (SOHO) devices, a common tactic for this group, to infiltrate vulnerable Versa Director systems via the exposed management ports. After gaining access, the attackers deployed a custom web shell named "VersaMem" to capture plaintext user credentials and monitor the Apache Tomcat web server's incoming traffic.

On June 21, Lumen researchers informed Versa about the vulnerability, shortly after they believed Volt Typhoon started exploiting it. Versa responded by issuing advisories on July 26 and August 8, outlining steps to reduce the risk. By August 26, they had published a detailed security bulletin describing the flaw and providing guidance for customers to protect their systems.

At least five organisations, including four based in the United States, have been compromised due to this vulnerability. These organisations are primarily from the managed service provider, internet service provider, and IT sectors. Given the seriousness of the situation, CISA has mandated that federal agencies apply the necessary mitigations by September 13 or cease using the vulnerable technology until it is secured.

Although the vulnerability was rated as moderately severe with a CVSS score of 6.6 out of 10, Versa has highlighted the significant risks associated with it. While the vulnerability is complex to exploit and requires high-level privileges, it becomes much easier to exploit if the management ports are exposed. In such cases, attackers can upload unauthorized files and execute code via the VersaMem web shell, leading to severe security breaches.

Versa has strongly advised its customers to update their systems to the latest versions, which include security enhancements that make the software more resistant to attacks. They have also recommended following their system hardening and firewall guidelines to reduce the likelihood of exploitation.

The Volt Typhoon group’s exploitation of the CVE-2024-39717 vulnerability highlights the ongoing threat posed by state-backed cyber actors. Although Versa has patched the vulnerability, organizations using Versa Director must act quickly to secure their systems and prevent further breaches. This incident serves as a reminder of the importance of keeping software updated and securing all network entry points to defend against sophisticated cyber threats.

CISA Cyber Attacks Ivanti Ivanti security flaws Ivanti VPN Exploitation Security Breach VPN VPN security

Lessons from the Ivanti VPN Cyberattack: Security Breaches and Mitigation Strategies

 

The recent cyberattack on Ivanti’s VPN software has prompted swift action from the Cybersecurity and Infrastructure Security Agency (CISA). This incident not only highlights the need for stronger cybersecurity measures but also raises important questions about exploit techniques, organizational responses to security breaches, and the escalating costs associated with downtime. 

The vulnerabilities in Ivanti’s VPN gateway allowed threat actors to bypass authentication and gain unauthorized access. Attackers could send maliciously crafted packets to infiltrate the system without needing to steal credentials, giving them access to user credentials, including domain administrator credentials. A second vulnerability enabled the injection of malicious code into the Ivanti appliance, allowing attackers to maintain persistent access, even after reboots or patches. Security researchers, including Mandiant, identified that Ivanti’s initial mitigations were insufficient. 

CISA warned that Ivanti’s interim containment measures were not adequate to detect compromises, leaving systems vulnerable to persistent threats. This uncertainty about the effectiveness of proposed mitigations necessitated CISA’s prompt intervention. The ability of attackers to gain persistent access to a VPN gateway poses significant risks. From this trusted position, attackers can move laterally within the network, accessing critical credentials and data. The compromise of the VPN allowed attackers to take over stored privileged administrative account credentials, a much more severe threat than the initial breach. In response to the breach, CISA advised organizations to assume that critical credentials had been stolen. 

Ivanti’s failure to detect the compromise allowed attackers to operate within a trusted zone, bypassing zero-trust principles and exposing sensitive data to heightened risks. The severity of the vulnerabilities led CISA to take the unusual step of taking two of Ivanti’s systems offline, a decision made to protect the most sensitive credentials. Despite later clarifications from Ivanti that patches could have been applied more discreetly, the miscommunications highlight the importance of clear, open channels during a crisis. Mixed messages can lead to unnecessary chaos and confusion. System-level downtime is costly, both in terms of IT resources required for shutdown and recovery and the losses incurred from service outages. 

The exact cost of Ivanti’s downtime remains uncertain, but for mission-critical systems, such interruptions are extremely expensive. This incident serves as a warning about the costs of addressing the aftermath of a cyberattack. CISA’s decision to shut down the systems was based on the potential blast radius of the attack. The trusted position of the VPN gateway and the ability to export stored credentials made lateral movement easier for attackers. 

Building systems based on the principle of least privilege can help minimize the blast radius of attacks, reducing the need for broad shutdowns. The Ivanti VPN cyberattack underscores the pressing need for robust cybersecurity measures. Organizations must adopt proactive infrastructure design and response strategies to mitigate risks and protect critical assets. Reducing the number of high-value targets in IT infrastructure is crucial. Privileged account credentials and stored keys are among the highest value targets, and IT leaders should prioritize strategies and technologies that minimize or eliminate such targets.

CISA Cyberattacks Cybercirme Cyberhackers CyberThreat HHS Microsoft Vulnerabilities and Exploits Windows

Microsoft Announces New Deadlines for Windows Updates

 


A July 4 deadline for Windows users who have not updated their systems is fast approaching. It was only two weeks ago that a two-week-old security vulnerability found in Windows was found to have been reactivated. Despite Microsoft's claim that CVE-2024-26169 is not exploitable, Symantec's security researchers believe otherwise, finding “some evidence” that attackers might have prepared an exploit for the CVE-2024-26169 vulnerability before patching the vulnerability. 

As of last month, several U.S. government agencies – including CISA and the FBI – have collaborated on a Cybersecurity Alert which warns that “Black Basta affiliates have compromised a wide range of critical infrastructure, businesses, and industries throughout North America, Europe and Australia.” There are over 500 organizations in the world that have been affected by Black Basta affiliates in the year 2024. 

Several organizations have released the joint CSA, including the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), the Department of Health and Human Services (HHS), and the Multi-State Information Sharing and Analysis Center (MS-ISAC), to provide information regarding the Black Basta attacks, which are referred to hereafter as the authoring organizations. A variant of ransomware known as Black Basta has encrypted and stolen data from at least 12 out of 16 critical infrastructure sectors, including the Healthcare and Public Health (HPH) sector. 

The FBI has conducted investigations into Black Basta and third parties have reported on these TTPs and IOCs. This is a ransomware-as-a-service variant that was first detected in April 2022 and is considered a ransomware-as-a-service (RaaS) variant. It is believed that the Black Basta ransomware will have affected more than 500 organizations globally by May 2024, affecting a wide range of businesses in North America, Europe, and Australia as well as critical infrastructures. 

Black Basta is a Russian-linked ransomware that originated in early 2022. It was used to attack over 329 organizations around the world and has grown to become one of the fourth most active strains of ransomware based on the number of victims. According to the group, they are using double-extortion tactics to extort victims by threatening to publish stolen data unless the victim is willing to pay a ransom. Several researchers have suggested that BlackBasta may have originated as a part of Conti Group, a ransomware gang that has been in operation for quite some time now. 

It has been revealed through the leak of Conti’s online chats that the group had ties to the Russian government and that it supported the invasion of Ukraine. The group ended in May 2022, but its online chats were leaking this information. Affiliates of Black Basta use common methods for gaining access to a system such as phishing emails and exploiting known vulnerabilities then use a double extortion technique to gain access to the system as well as steal data. There are two types of ransom notes: those which include instructions as to how to pay as well as those which do not.

The ransomware group instead gives victims a one-time use private code and instructs them to contact the group via a website that is only accessible through the Tor browser, a URL that contains a .onion extension. According to the majority of ransom notes, victims are usually given between 10 and 12 days before becoming subject to the publication of their data on the Basta News website, which the Black Basta ransomware group runs. Black Basta attacks businesses in a range of different industries, affecting the construction industry (10% of victims), the legal sector (4%) and the real estate sector (3%). This group of ransomware is known as Black Basta and its victimology is very similar to that of the Conti ransomware group.

Both groups have a shared appetite for many of the same industries as Black Basta. Among the victims of Black Basta, 61% are from organizations that are based in the United States, followed by 15% from the German authorities. There are several high-profile victims of Black Basta, which include Capita, a software services company with billions of dollars worth of UK government contracts, and ABB, a company that has more than US$29 billion in revenue. The information regarding whether or not a ransom was paid by either company has not been publicized.

The healthcare industry is an attractive target for cybercriminals due to the size of the organization, the technological dependence, the access to medical information and the unique impact of disruptions to patient care. There are several ways in which a member of the Black Basta organization will gain access to a system, and these methods include phishing emails, exploiting known vulnerabilities, and then using double extortion techniques to gain access to the system as well as stealing data. A ransom note can be divided into two types: those that provide instructions on how to pay the ransom, and those which do not provide instructions. 

As an alternative to encrypting the victims' files, the ransomware group comprises a group of individuals that give victims an individual one-use private code in addition to instructing them to contact the group via a website only accessible by Tor browsers, one that contains a .onion extension on the URL. There is usually between 10 and 12 days of grace allowed to victims according to ransom notes that are generally released by the Black Basta malware group before their data is exposed on Basta News, which is a website that publishes data from the victims. 

It is not uncommon for Black Basta to attack businesses across a wide range of different industries, with 10 per cent of victims coming from the construction industry, 4 per cent from the legal sector, and 3 per cent from the real estate industry. It seems that the Black Basta ransomware group, which has a victimology very similar to that of the Conti ransomware group, has been seen to distribute a similar type of ransomware. There is a clear affinity between the two groups when it comes to several of the same industries as Black Basta.

Black Basta has been responsible for the murder of 61% of American victims, followed by 16% of German victims, and the vast majority of victims belong to organizations based in the United States and Europe. The Black Basta scam has claimed the lives of several high-profile companies, including Capita, a software company with billions of dollars worth of contracts with the British government, and ABB, a company with one of the world's largest revenue bases within the US$29 billion range. Neither company has provided any information regarding a ransom payment that has been made by one of the companies, which is of concern. 

The healthcare industry represents an appealing target for cybercriminals due to several critical factors. Firstly, the sheer size and scale of healthcare organizations make them lucrative targets. Additionally, their substantial reliance on advanced technology heightens vulnerability to cyberattacks. Furthermore, these organizations possess extensive repositories of sensitive medical information, making them particularly attractive to malicious actors. The potential disruptions to patient care resulting from cyber incidents also underscore the unique and profound impact of such breaches within the healthcare sector.

From Code to Chaos: BlackSuit Ransomware and The CDK Global Cyber Crisis


In recent days, the automotive industry has been hit by a significant IT outage that has disrupted operations for car dealerships across North America. The culprit? The notorious BlackSuit ransomware gang. In this blog post, we’ll delve into the details of the attack, its impact, and what it means for CDK Global and its customers.

The Incident

According to people familiar with the situation, the BlackSuit ransomware gang is responsible for CDK Global's significant IT failure and interruption to car dealerships throughout North America.

The conversations follow the BlackSuit ransomware assault, which led CDK to lock down its IT infrastructure and data centers, including its car dealership platform, to prevent the attack from spreading. The company attempted to restore services on Wednesday, but a second cybersecurity attack forced it to shut down all IT systems again.

The Attack

CDK Global, a leading provider of technology solutions for auto dealerships, found itself in the crosshairs of cybercriminals. 

While the company has yet to officially confirm the ransomware attack, multiple sources indicate that BlackSuit is behind the incident. The attack likely exploited vulnerabilities in CDK’s systems, leading to widespread disruption.

Impact on Dealerships

Two of the largest public car dealership companies, Penske Automotive Group and Sonic Automotive, disclosed that they, too, were impacted by the outages.

The fallout from the CDK Global outage has been substantial. Car dealerships rely heavily on CDK’s software for inventory management, sales, and customer service. 

With the systems down, dealers have had to resort to manual processes, including pen-and-paper record-keeping. Imagine the chaos in a busy dealership trying to manage sales, service appointments, and parts inventory without their usual digital tools.

Data Theft Concerns

Beyond the immediate operational challenges, there are serious concerns about data theft. Ransomware attacks often involve stealing sensitive information before encrypting files and demanding a ransom.

CDK Global must now investigate whether customer data, financial records, or other critical information has been compromised. The potential fallout from such a breach could be long-lasting and damaging.

Response and Recovery

In November 2023, the FBI and CISA published in a joint advisory that Royal and BlackSuit's encryptors use similar strategies and have coding overlaps.

CDK Global’s response to the attack is crucial. They need to assess the extent of the breach, restore systems, and enhance security measures. Communication with affected dealerships is equally important. Dealers need transparency about the situation, timelines for resolution, and guidance on how to navigate the outage.

Hackers Reveal Their Strategy of Stealing Snowflake's Ticketmaster Data

 

Ticketmaster and other organisations' Snowflake accounts were said to have been accessed by a ShinyHunters hacker via a breach of software engineering firm EPAM Systems, validating a Mandiant report attributing some of the intrusions to third-party contractor hacks, Wired reported. 

According to the hacker, information-stealing malware and a remote access trojan deployed against one of EPAM Systems' Ukraine-based employees allowed ShinyHunters to gain access to unencrypted credentials used by the employee to access the firm's customers' Snowflake accounts, which were then used to infiltrate the Snowflake accounts, including the one owned by Ticketmaster. 

EPAM ruled out the ShinyHunters hacker's claims, but independent security researcher "Reddington" discovered an infostealer-harvested data repository online, including the internal EPAM URL to Ticketmaster's Snowflake account and the credentials employed by the EPAM worker to access Ticketmaster's account. 

"This means that anyone that knew the correct URL to [Ticketmaster’s] Snowflake could have simply looked up the password, logged in, and stolen the data" noted Reddington. 

In the hacking campaign targeting Snowflake's clients, nearly 165 customer accounts were potentially compromised, but only a few of these have been identified thus far. In addition to Ticketmaster, the banking corporation Santander has recognised that their data was stolen but has neglected to name the account from which it was taken. 

However, a local media outlet has confirmed that it was a Snowflake account; the stolen data included bank account information for 30 million customers, including 6 million account numbers and balances, 28 million credit card numbers, and human resources information about employees, according to a post published by the hackers. Lending Tree and Advance Auto Parts have also confirmed that they could possibly be victims of this campaign. 

In a notice published earlier this week, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) urged that organisations follow Snowflake's recommendations to look for signals of odd behaviour and take precautions to prevent unauthorised access. A similar advice issued by the Australian Signals Directorate's Australian Cyber Security Centre (ACSC) warned of "successful compromises of several companies using Snowflake environments.”

White House
CISA Cyber Security data security Google Mandiant Mandiant Threat Intelligence ransomware attacks Social Engineering White House

Rising Ransomware Attacks Highlight Persistent Cybersecurity Challenges

 


Despite global law enforcement efforts and heightened attention from the White House, ransomware incidents continue to rise unabated, according to a new report from cybersecurity firm Mandiant. Researchers at the Google-owned company identified 50 new ransomware variants in 2023, with about a third branching off existing malware. This underscores the pervasive nature of the problem and the challenges in curbing cyber extortion. 

In 2023 alone, cybercriminals amassed over $1 billion from victim ransom payments, highlighting the lucrative nature of these attacks. The healthcare sector has been particularly hard-hit, with hospitals experiencing significant disruptions. The report noted that Ascension, one of the nation's largest healthcare systems with 140 hospitals across 19 states, was recently impacted by the Black Basta ransomware variant. The ongoing outage is raising concerns about patient safety and the potential risk to lives. Mandiant's findings align with a recent White House report on national cybersecurity, which also noted an increase in ransomware attacks. 

However, one significant issue is that reporting ransomware incidents is largely voluntary. This means assessments of ransomware prevalence often rely on data from cybersecurity companies, whose understanding is based on their customer base and the cybercriminal communities they monitor. To address this, the Cybersecurity and Infrastructure Security Agency (CISA) is finalizing a mandate requiring critical infrastructure owners and operators to report ransomware payments within 24 hours. This mandate aims to provide a more comprehensive view of ransomware activity and enhance response efforts. 

Mandiant's assessment highlights a 75% year-over-year increase in posts on data leak sites, which extortionists use to pressure companies into paying ransoms. The firm noted that 2023 saw the highest number of data-leak site posts since tracking began in 2020. Additionally, there was a 20% increase in the number of investigations led by Mandiant, indicating a significant rise in ransomware activities. The most prolific ransomware variants observed were ALPHV and LOCKBIT, each accounting for 17% of all activity. The surge in ransomware attacks in 2023 followed a slight dip in extortion activities in the previous year. Mandiant researchers suggested that the dip in 2022 might have been an anomaly caused by external factors such as the Russian invasion of Ukraine or the leaked Conti chats, which may have temporarily disrupted cybercriminal operations. 

As law enforcement agencies continue to conduct global operations against ransomware gangs, the evolving tactics and persistent nature of these cybercriminals highlight the need for continuous vigilance and enhanced cybersecurity measures. The collaboration between government agencies, cybersecurity firms, and critical infrastructure operators is crucial in building a robust defense against the relentless threat of ransomware.

New Ransomware Threat Hits Hundreds of Organisations Worldwide

 


In a recent joint report by the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI), a new ransomware gang named Black Basta has been identified as breaching over 500 organisations globally between April 2022 and May 2024. This group has targeted various sectors, including healthcare, spanning across North America, Europe, and Australia.

Black Basta, coming through as a Ransomware-as-a-Service (RaaS) operation in April 2022, has quickly gained notoriety by attacking numerous high-profile victims such as Rheinmetall, Hyundai, Capita, and the American Dental Association, among others. Believed to have connections to the former Conti cybercrime syndicate, Black Basta operates with sophistication and a steady stream of initial access to its targets.

One of the key tactics employed by Black Basta involves stealing corporate data before encrypting a company's devices. This stolen data is then used in double-extortion attacks, where victims have demanded a ransom to prevent the publishing of their sensitive information. The gang's data leak site, 'Black Basta Blog' or 'Basta News,' lists victims and progressively releases data to pressure them into paying the ransom.

Technical analysis reveals that Black Basta utilises the ChaCha20 encryption algorithm to encrypt files, rendering them inaccessible without the decryption key. Victims are left with a custom extension appended to their encrypted files (.basta), along with a ransom note providing instructions on how to negotiate with the threat actors.

Responding to this spreading threat, federal agencies advise organisations to maintain up-to-date operating systems, employ phishing-resistant Multi-Factor Authentication (MFA), and train users to identify and report phishing attempts. Moreover, securing remote access software and implementing recommended mitigations are essential steps in blocking the risks posed by Black Basta and similar ransomware attacks.

Healthcare organisations are particularly vulnerable, given their size, technological reliance, and access to sensitive patient information. CISA and the FBI have suggested adhering to the StopRansomware Guide in order to dodge potential attacks in the healthcare sector.

Recent incidents, including an attack on healthcare giant Ascension, accentuate the urgency of addressing the threat posed by Black Basta. With the gang's ability to readily expand its victim pool and employ coercive tactics, organisations must remain particularly careful and implement robust cybersecurity measures to mitigate the risk of falling victim to ransomware attacks.

Considering the course of events, cybersecurity experts emphasise the importance of ardent measures, including regular backups, system updates, and employee training, to strengthen defences against ransomware threats like Black Basta. This calls for collective efforts to combat the growing menace of ransomware and protect critical infrastructure from malicious actors.

CISA Company Security FBI Path Traversal Vulnerabilties and Exploits

CISA Ask Companies to Fix Path Traversal Vulnerabilities


CISA and FBI urge companies to take patch actions 

CISA and the FBI recommended software companies today to assess their products and fix route traversal security flaws before selling.

Attackers can leverage path traversal vulnerabilities (also known as directory traversal) to create or overwrite important files used to execute malware or circumvent security systems such as authentication. 

“Additionally, this Alert highlights the prevalence, and continued threat actor exploitation of, directory traversal defects. Currently, CISA has listed 55 directory traversal vulnerabilities in our Known Exploited Vulnerabilities (KEV) catalog,” says the CISA and FBI joint report.

Impact of these security loops

Such security holes can also allow threat actors to acquire sensitive data, such as credentials, which can then be used to brute-force existing accounts and compromise the targeted systems.

Another option is to disable or limit access to vulnerable systems by overwriting, destroying, or altering critical authentication files (which would lock out all users).

CISA and the FBI propose that software buyers ask vendors if they completed formal directory traversal testing. 

To eliminate this type of problem from all goods, manufacturers should ensure that their software developers immediately install the necessary mitigations. Integrating security into products from the start can eliminate directory traversal issues.

About directory traversal vulnerabilities

Directory traversal vulnerabilities occur when users manipulate inputs, such as file paths, to gain unauthorized access to application files and directories. Malicious cyber actors can use these exploits to access restricted directories and read, change, or write arbitrary files, which can have adverse effects.

How Can Software Vendors Avoid Directory Traversal Risks?

To minimize directory traversal vulnerabilities in software products, developers should apply proven mitigations such as:

  • Use random identification and store metadata independently (e.g., in a database) instead of relying on user input for a file name.
  • If the previous strategy is not followed, restrict file names to alphanumeric characters. Please ensure that submitted files do not have executable permissions.

Path vulnerabilities ranked eighth on MITRE's list of the 25 dangerous software issues, trailing only out-of-bounds write, cross-site scripting, SQL injection, use-after-free, OS command injection, and out-of-bounds read flaws.

In March, CISA and the FBI released another "Secure by Design" alert, advising executives of software manufacturing companies to develop mitigations to prevent SQL injection (SQLi) security risks.

SQLi vulnerabilities were listed third among MITRE's top 25 most hazardous software vulnerabilities between 2021 and 2022, trailing only out-of-bounds writes and cross-site scripting.

Protecting Users Against Bugs: Software Providers' Scalable Attempts

Protecting Users Against Bugs

Ransomware assaults, such as the one on Change Healthcare, continue to create serious disruptions. However, they are not inevitable. Software developers can create products that are immune to the most frequent types of cyberattacks used by ransomware gangs. This blog discusses what can be done and encourages customers to demand that software companies take action.

Millions of Americans recently experienced prescription medicine delays or were forced to pay full price as a result of a ransomware assault. While the United States has begun to make headway in reacting to cyberattacks, including the passage of incident reporting requirements into law, it is apparent that much more work remains to be done to combat the ransomware epidemic. 

Ransomware gangs flourish because they usually attack genuinely easy weaknesses in software that serve as the basis for critical operations and services.

Providing scalable solutions: Company duty

Business leaders of software manufacturers hold the key: They can build products that are resilient against the most common classes of cyberattacks by ransomware gangs.

The security community has known how to eliminate classes of vulnerabilities across software for decades. What is needed is not perfectly secure software but “secure enough” software, which software manufacturers are capable of creating.n exploit remarkably simple vulnerabilities in software that is the foundation for the essential processes and services.

Systemic classes of defects like SQL injection or insecure default configurations, such as a lack of multi-factor authentication by default or hardcoded default passwords, enable the vast majority of ransomware attacks and are preventable at scale.

The expense of preventing some types of vulnerabilities during the design stage is substantially less than dealing with the complex aftermath of a breach. 

According to a recent Google study, it has nearly eliminated many common types of vulnerabilities in its products, such as SQL injection and cross-site scripting. Furthermore, Google claims that such tactics were cost-effective and, in some cases, saved money ultimately as a result of having to worry about bugs.

Fighting lack of action

Inaction is exactly what has occurred in the software business. The Biden administration's National Cybersecurity Strategy asks for a shift in this direction, with software manufacturers accepting responsibility for product security from the start.

For example, whereas conventional vulnerability assessment approaches urge a sequential approach to identifying and patching vulnerabilities one by one, the agency's SQL injection alert promotes software manufacturers' executives to lead codebase reviews and eliminate all potentially unsafe functions to prevent SQL injection at the source.

How to identify bugs

Software vendors may assess vulnerability classes on two levels: impact, or the degree of damage that can be done by that class of vulnerability, and the cost of avoiding that flaw at scale.

SQL injection vulnerabilities are likely to be high in impact but inexpensive in cost to eliminate, whereas memory-safety issues have extremely high impact but need large investments to rewrite codebases systematically. Businesses can create a priority list of the most cost-effective tasks for fixing specific types of flaws in their products.

Customer's role: What can you do?

Companies should ask how their vendors attempt to remove entire classes of threats, such as implementing phishing-resistant multi-factor authentication and developing a memory-safe plan to address the most prevalent type of software vulnerability.

It is feasible that future ransomware assaults may be far more difficult to carry out. It's high time for software businesses to make this possibility a reality and safeguard Americans by including security from the beginning. Customers should insist that they do this.
