Change Healthcare Restores Clearinghouse Services After Nine-Month Recovery From Ransomware Attack

 

Change Healthcare has announced the restoration of its clearinghouse services, marking a significant milestone in its recovery from a debilitating ransomware attack by the ALPHV/Blackcat group in February. 

The attack caused unprecedented disruption to one of the U.S.’s most critical healthcare transaction systems, which processes over 15 billion transactions annually and supports payments and communications for hospitals, healthcare providers, and patients. The breach led to widespread financial and operational issues, with the American Hospital Association (AHA) reporting that 94% of U.S. hospitals relying on Change Healthcare were affected. Many hospitals experienced severe cash flow challenges, with nearly 60% reporting daily revenue losses of $1 million or more. These difficulties persisted for months as Change Healthcare scrambled to restore its services and mitigate the attack’s impact. 

In response to the financial strain on healthcare providers, UnitedHealth-owned Optum launched a Temporary Funding Assistance Program in March. This initiative provided over $6 billion in interest-free loans to healthcare providers to address cash flow shortages. As of October, $3.2 billion of the funds had been repaid, reflecting progress in stabilizing the industry. However, some services, such as Clinical Exchange, MedRX, and the Payer Print Communication System, are still undergoing restoration, leaving providers to navigate ongoing challenges. 

The breach also exposed sensitive information of approximately 100 million individuals, making it one of the most significant healthcare data breaches in history. Victims’ full names, email addresses, banking details, and medical claims records were among the data compromised. Change Healthcare’s parent company, UnitedHealth, confirmed that the attackers gained access through stolen credentials used to log into a Citrix portal that lacked multi-factor authentication (MFA). UnitedHealth CEO Andrew Witty testified before Congress, admitting to authorizing a $22 million ransom payment to the attackers. He described the decision as one of the hardest he had ever made, emphasizing the urgent need to minimize further harm to the healthcare system. 

Cybersecurity experts have criticized Change Healthcare for failing to implement basic security protocols, including MFA and robust network segmentation, prior to the attack. The attack’s aftermath has been costly, with remediation expenses exceeding $2 billion as of the most recent UnitedHealth earnings report. Critics have described the company’s lack of preventive measures as “egregious negligence.” Tom Kellermann, SVP of cyber strategy at Contrast Security, highlighted that the company failed to conduct adequate threat hunting or prepare for potential vulnerabilities, despite its critical role in the healthcare ecosystem. 

Beyond the immediate financial impact, the incident has raised broader concerns about the resilience of U.S. healthcare infrastructure to cyberattacks. Experts warn that the sector must adopt stronger cybersecurity measures, including advanced threat detection and incident response planning, to prevent similar disruptions in the future. The restoration of Change Healthcare’s clearinghouse services represents a major step forward, but it also serves as a reminder of the severe consequences of insufficient cybersecurity measures in an increasingly digital healthcare landscape. 

The attack has underscored the urgent need for organizations to prioritize data security, invest in robust safeguards, and build resilience against evolving cyber threats.

Prometei Botnet: The Persistent Threat Targeting Global Systems

 

The Prometei botnet, active since at least 2016, continues to pose a persistent threat worldwide by exploiting unpatched software vulnerabilities. First identified in 2020, Prometei has since infected over 10,000 systems across diverse regions, including Brazil, Indonesia, Turkey, and Germany. Its resilience stems from its focus on widely used software gaps, particularly in systems with weak configurations, unmonitored security measures, or outdated patches. The Federal Office for Information Security in Germany has labeled it a medium-impact threat, given its extensive reach and ability to bypass security protocols. Prometei operates by exploiting vulnerabilities in widely used software, spreading particularly through unpatched or poorly configured Exchange servers. 

Critical Start’s Callie Guenther highlights Prometei’s strategy of leveraging regions with inadequate cybersecurity, making it highly effective in targeting various systems regardless of location. One notable aspect is its ability to spread through legacy vulnerabilities, such as the BlueKeep flaw in Remote Desktop Protocol (RDP), which has a critical CVSS score of 9.8. By targeting these known issues, Prometei can quickly access poorly maintained systems that remain unprotected. A Prometei attack often starts with a series of network login attempts, typically originating from locations associated with known botnet infrastructure. Once access is secured, the malware tests various system weaknesses, particularly outdated vulnerabilities like BlueKeep and EternalBlue. If successful, it can propagate through Server Message Block (SMB) systems or use ProxyLogon flaws to exploit Windows environments further. 

Prometei’s use of outdated exploits could be seen as less sophisticated; however, its approach is strategic, focusing on identifying vulnerable, under-maintained systems rather than tackling those with robust security protocols. Once established in a target system, Prometei employs several techniques to maintain control and evade detection. For example, it uses a domain generation algorithm (DGA) to enhance its command-and-control (C2) system, allowing continuous operation even if some domains are blocked. It further manipulates firewall settings to ensure its traffic is not obstructed, enabling it to persist even after system reboots. Among its advanced methods is the use of the WDigest protocol, which stores plaintext passwords in memory. 

Prometei forces systems to store passwords in plaintext, then exfiltrates them while bypassing detection by configuring Windows Defender to ignore specific files. The primary goal of Prometei appears to be cryptojacking, as it harnesses infected systems to mine the Monero cryptocurrency without the owners’ knowledge. Additionally, it installs an Apache web server as a web shell, creating a backdoor for attackers to upload more malicious files or execute commands. Prometei’s presence, according to Trend Micro’s Stephen Hilt, often signals deeper security concerns, as it can coexist with other malicious software, highlighting vulnerabilities that attackers may leverage for various purposes. Interestingly, Prometei avoids certain regions, specifically targeting systems outside former Soviet countries. Its command-and-control servers bypass exit nodes within these nations, avoiding accounts tagged as “Guest” or “Other user” in Russian.

Older versions of Prometei also included Russian-language settings, hinting at a potential connection to Russian-speaking developers. The botnet’s name, “Prometei,” references the Greek titan Prometheus, symbolizing a persistence that echoes the botnet’s own sustained presence in global cyber threats. Prometei exemplifies the persistent and evolving nature of modern botnets. Its success in exploiting well-known but unpatched vulnerabilities underscores the importance of maintaining updated security systems. For organizations worldwide, especially those with legacy systems or lax monitoring, Prometei serves as a critical reminder to reinforce defenses against cyber threats, as outdated security leaves systems vulnerable to malicious actors seeking to exploit any gap available.

Mitigating the Risks of Shadow IT: Safeguarding Information Security in the Age of Technology

 

In today’s world, technology is integral to the operations of every organization, making the adoption of innovative tools essential for growth and staying competitive. However, with this reliance on technology comes a significant threat—Shadow IT.  

Shadow IT refers to the unauthorized use of software, tools, or cloud services by employees without the knowledge or approval of the IT department. Essentially, it occurs when employees seek quick solutions to problems without fully understanding the potential risks to the organization’s security and compliance.

Once a rare occurrence, Shadow IT now poses serious security challenges, particularly in terms of data leaks and breaches. A recent amendment to Israel’s Privacy Protection Act, passed by the Knesset, introduces tougher regulations. Among the changes, the law expands the definition of private information, aligning it with European standards and imposing heavy penalties on companies that violate data privacy and security guidelines.

The rise of Shadow IT, coupled with these stricter regulations, underscores the need for organizations to prioritize the control and management of their information systems. Failure to do so could result in costly legal and financial consequences.

One technology that has gained widespread usage within organizations is ChatGPT, which enables employees to perform tasks like coding or content creation without seeking formal approval. While the use of ChatGPT itself isn’t inherently risky, the lack of oversight by IT departments can expose the organization to significant security vulnerabilities.

Another example of Shadow IT includes “dormant” servers—systems connected to the network but not actively maintained. These neglected servers create weak spots that cybercriminals can exploit, opening doors for attacks.

Additionally, when employees install software without the IT department’s consent, it can cause disruptions, invite cyberattacks, or compromise sensitive information. The core risks in these scenarios are data leaks and compromised information security. For instance, when employees use ChatGPT for coding or data analysis, they might unknowingly input sensitive data, such as customer details or financial information. If these tools lack sufficient protection, the data becomes vulnerable to unauthorized access and leaks.

A common issue is the use of ChatGPT for writing SQL queries or scanning databases. If these queries pass through unprotected external services, they can result in severe data leaks and all the accompanying consequences.

Rather than banning the use of new technologies outright, the solution lies in crafting a flexible policy that permits employees to use advanced tools within a secure, controlled environment.

Organizations should ensure employees are educated about the risks of using external tools without approval and emphasize the importance of maintaining information security. Proactive monitoring of IT systems, combined with advanced technological solutions, is essential to safeguarding against Shadow IT.

A critical step in this process is implementing technologies that enable automated mapping and monitoring of all systems and servers within the organization, including those not directly managed by IT. These tools offer a comprehensive view of the organization’s digital assets, helping to quickly identify unauthorized services and address potential security threats in real time.

By using advanced mapping and monitoring technologies, organizations can ensure that sensitive information is handled in compliance with security policies and regulations. This approach provides full transparency on external tool usage, effectively reducing the risks posed by Shadow IT.

The Role of Immutable Data Storage in Strengthening Cybersecurity


 

In today’s rapidly advancing digital world, how organisations store their data is crucial to their cybersecurity strategies. Whether protecting sensitive customer information, securing intellectual property, or ensuring smooth business operations, effective data storage methods can prominently impact an organisation's defence against cyber threats.

Modern businesses are experiencing a massive increase in data generation. This surge is driven by technological innovation, growing customer interactions, and expanding business operations. As data continues to grow at an exponential rate, organisations must find ways to fully utilise this data while also ensuring its security and availability.

Cyberattacks are becoming more frequent and sophisticated, making data protection a top priority for businesses. Ransomware attacks, in particular, are a major concern. These attacks involve cybercriminals encrypting an organisation’s data and demanding a ransom for its release. According to the Verizon 2023 Data Breach Investigations report, ransomware is involved in over 62% of incidents linked to organised crime and 59% of financially motivated incidents. The consequences of such attacks are severe, with businesses taking an average of 9.9 days to return to normal operations after a ransomware incident. Additionally, 1 in 31 companies worldwide faces weekly ransomware attacks, underscoring the urgent need for robust data protection measures.

Immutable data storage has become a key strategy in bolstering cybersecurity defences. Unlike traditional storage methods, which allow data to be modified or deleted, immutable storage ensures that once data is written, it cannot be altered or erased. This feature is crucial for maintaining data integrity and protecting critical information from tampering and unauthorised changes.

By adopting immutable storage solutions, organisations can significantly reduce the risks associated with cyberattacks, particularly ransomware. Even if attackers manage to penetrate the network, the immutable data remains unchanged and intact, rendering ransom demands ineffective. This approach not only protects sensitive information but also helps maintain business continuity during and after an attack.

As businesses continue to face the growing threat of cybercrime, adopting advanced data storage solutions like immutable storage is essential. By ensuring that data cannot be altered or deleted, organisations can better protect themselves from the devastating impacts of cyberattacks, safeguard critical information, and maintain operations without interruption. In an age where data is both a valuable asset and a prime target, robust storage strategies are indispensable to a comprehensive cybersecurity strategy.

Government Struggles with Low Arrest Rate Amidst 31 Lakh Cyber Fraud Complaints

 

From the high-profile AIIMS cyber attack to widespread data leaks like that of the ICMR, the National Cyber Crime Portal (NCRP) has seen an alarming rise in cyber fraud complaints. Since 2020, the portal has received 31 lakh complaints as of February 2024. 

However, the most concerning issue, as highlighted by the Central government's official communication, is the staggeringly low number of arrests in these cases. Despite over 66,000 cases being registered by various law enforcement agencies, the total number of arrests stands at just 500, amounting to less than 1% of the reported cases. 

This discrepancy has been a recurring topic in meetings within the Ministry of Home Affairs and the Ministry of Finance. During a recent Financial Stability and Development Council (FSDC) meeting, several stakeholders voiced their frustration over the minimal progress in arrests. A significant part of the problem lies in the increasing prevalence of fraudulent loan lending apps, which have severely impacted India's financial infrastructure. 

These apps disproportionately affect low-income groups, leading to significant financial losses as money is often funneled out of the country. According to a senior official present at the FSDC meeting, many of these apps operate from China, posing a dual threat to both financial institutions and the economic stability of vulnerable populations. The official noted that some Indian nationals involved in these crimes inadvertently aid China-based operators, thereby becoming victims themselves. 

In response to these growing concerns, the central government has urged tech giants like Google and Meta to deploy experts to combat the menace. There is a heightened alarm over advertisements run by organized threat actors, many of whom operate internationally. A central cyber agency's analysis revealed that numerous mobile applications were conducting ad campaigns on Meta platforms, leading to a slew of suicides linked to harassment and extortion by illegal app operators and loan recovery agents. 

The misuse of app permissions for harvesting credentials and data adds another layer of risk, potentially enabling future cybercrimes. The FSDC meeting underscored the urgency of addressing these issues, with multiple stakeholders pushing for the Ministry of Home Affairs to take immediate action. Sources indicate that the Ministry is now expected to convene a meeting with various agencies to expedite investigations and increase the number of arrests. 

This coordinated effort aims to enhance the pace and effectiveness of law enforcement responses to cyber fraud, thereby protecting India's financial ecosystem and its most vulnerable citizens.

Understanding Vishing and Quishing: Protecting Yourself Against Telephone and QR Code Scams

 

In our digitally interconnected world, cybercriminals continuously devise new methods to exploit technology for their malicious intents. Two prevalent schemes gaining traction are vishing and quishing scams. These fraudulent activities capitalize on telephone calls and QR codes to deceive unsuspecting individuals into revealing sensitive personal and financial information. 

Vishing, derived from "voice" and "phishing," entails perpetrators posing as trusted entities over the phone to trick individuals into sharing confidential data like bank account details or passwords. Employing tactics such as urgent requests or threats of repercussions, these scammers manipulate victims into compliance. For instance, a vishing scam might involve a caller impersonating a bank representative, claiming an account issue that necessitates immediate action from the victim. 

Alternatively, fraudsters may masquerade as technical support agents from reputable companies, coercing victims into paying for unnecessary services or software under false pretenses of fixing non-existent computer problems. Another vishing variant, the "police officer tactic," targets vulnerable individuals, particularly the elderly, by feigning as law enforcement officers. Fabricating stories about imminent criminal threats, these scammers persuade victims to surrender valuables or cash, ostensibly for protection. 

On the flip side, quishing represents a newer cybercrime form exploiting QR codes to entice victims to fraudulent websites for data compromise. With QR code prevalence in daily life, quishing has become an increasingly insidious threat. Cybercriminals send deceptive emails containing QR codes, enticing recipients to scan them with their smartphones under false pretenses. Once scanned, these QR codes redirect users to malicious websites designed to distribute malware-infected files or capture login credentials entered by unsuspecting victims. 

Seamless QR code scanning integration into daily activities makes it easy for individuals to fall prey to quishing attacks without recognizing the danger. Protecting against vishing and quishing necessitates heightened vigilance and adherence to cybersecurity best practices. When receiving unsolicited phone calls, it's crucial to verify the caller's identity by independently contacting the organization they claim to represent using official contact information. 

Refrain from divulging personal or financial information over the phone unless legitimacy is verified. To guard against quishing scams, exercise caution when scanning QR codes, especially from unfamiliar or suspicious sources. Verify the website URL before entering sensitive information and ensure it's encrypted (https). Additionally, consider enabling multi-factor authentication for online accounts to add an extra security layer against unauthorized access. 

By staying informed about vishing and quishing tactics and implementing proactive security measures, individuals can safeguard themselves from falling victim to these malicious schemes. Awareness and caution remain paramount in protecting personal and financial well-being in today's digital landscape.

Strengthening Password Security: Addressing Misconceptions and Best Practices

 

According to recent research by the Institution of Engineering and Technology (IET), conducted to mark World Password Day, only one in five people in the UK can correctly identify a secure password over a risky one. This alarming statistic underscores the widespread lack of awareness and understanding when it comes to password security among the public. 

The study revealed that despite expressing concern about the possibility of being hacked in the future, a significant portion of the population continues to engage in risky password practices. For example, 20% of respondents admitted to using the same password for multiple websites and devices, a practice strongly discouraged by cybersecurity experts. 

Additionally, many individuals rely on easily guessable passwords, such as pet names or significant dates, further compromising their online security. Despite the prevailing fear of cyber threats, there exists a notable discrepancy between public perception and best practices in password security. While 84% of respondents believe that hackers are becoming more inventive, many still hold misconceptions about what constitutes a secure password. 

For instance, a significant portion of the population mistakenly believes that replacing letters with numbers in passwords enhances security, when in reality, this practice does little to deter sophisticated cyberattacks. Dr. Junade Ali, a cybersecurity expert and IET fellow, highlighted the critical importance of strong passwords in today's digital landscape. Weak and predictable passwords serve as easy targets for cybercriminals, who employ various tactics, including credential stuffing, to gain unauthorized access to multiple accounts. Credential stuffing exploits the common practice of using the same password across multiple platforms, allowing hackers to compromise multiple accounts with minimal effort. 

To address these vulnerabilities, the IET has issued recommendations aimed at improving password security awareness and practices. Among these recommendations is the suggestion to create randomly generated, long, and unique passwords for each website or online service. Longer passwords are generally more resistant to brute-force attacks and provide an added layer of security against unauthorized access.  

Additionally, the use of a reputable password manager is encouraged to securely store and manage passwords across various platforms. Password managers not only simplify the process of generating and storing complex passwords but also provide alerts in the event of a data breach, allowing users to take immediate action to protect their accounts.
