2024’s Most Dangerous Malware: A Wake-Up Call for Cybersecurity

 

OpenText, a leader in cybersecurity insights, has released its eagerly awaited “Nastiest Malware of 2024” list, highlighting some of the most destructive and adaptive cyber threats of the year. The list illustrates how ransomware and other malicious software continue to evolve, particularly regarding their impact on critical infrastructure. As cybercriminals refine their tactics, the need to strengthen cybersecurity measures has become increasingly urgent. Organizations around the globe are projected to boost their cybersecurity spending by 14.3% in 2024, raising total investments to over $215 billion, which reflects the magnitude of the challenges posed by these threats. 

LockBit claimed the title of the most dangerous malware of the year. This ransomware-as-a-service (RaaS) entity has demonstrated its ability to evade law enforcement efforts, including those from the FBI. Its ongoing attacks on critical infrastructure showcase its resilience and technical prowess. According to the FBI, LockBit was responsible for 175 reported attacks on essential systems in 2023 alone. The group’s bold ambition to target one million businesses emphasizes its threat level and solidifies its position in the ransomware landscape. 

Akira, a relatively new player, has rapidly gained infamy for its aggressive tactics. This ransomware has been particularly active in industries such as healthcare, manufacturing, and finance, using advanced encryption methods to cause significant disruption. Its retro-inspired branding contrasts sharply with its destructive potential, making it a popular choice among cybercriminal affiliates. 

Meanwhile, RansomHub, which may have connections to the infamous Black Cat (ALPHV) group, has made headlines with its high-profile attacks, including a daring strike on Planned Parenthood that compromised sensitive patient data. 

Other significant threats include Dark Angels, recognized for its precision-targeted attacks on Fortune 50 companies, and Play Ransomware, which takes advantage of vulnerabilities in FortiOS systems and RDP servers. Redline Stealer, while not technically ransomware, this type of threat significantly endangers organizations by focusing on stealing credentials and sensitive information. Each of these threats illustrates how cybercriminals are continually pushing the limits, employing advanced tactics to stay ahead of defenses. 

Muhi Majzoub, OpenText’s EVP and Chief Product Officer, notes that the increase in ransomware targeting critical infrastructure highlights the growing risks to national security and public safety. At the same time, the heightened emphasis on cybersecurity investments is a positive indication that organizations are recognizing these threats. However, the ability of ransomware groups to adapt remains a significant worry, as these criminals continue to leverage new technologies, including artificial intelligence, to create more sophisticated attacks. 

The findings from this year reveal a harsh truth: while progress in cybersecurity is being made, the rapid pace of innovation in malware development poses an ongoing challenge. As companies enhance their vigilance and dedicate more resources to protect vital systems, the battle against cyber threats is far from finished. The changing nature of these attacks requires ongoing adaptation, collaboration, and investment to protect the essential services that support modern society.

C2 Chinese Hackers Chinese Threat Actors Cyber Attacks Malware Attack NCSC Sophos TLS

NCSC Unveils “Pigmy Goat” Malware Targeting Sophos Firewalls in Advanced Chinese Cyberattack

 

The National Cyber Security Centre (NCSC) recently disclosed the presence of a Linux malware, “Pigmy Goat,” specifically designed to breach Sophos XG firewall devices. This malware, allegedly developed by Chinese cyber actors, represents a significant evolution in network infiltration tactics due to its complexity and advanced evasion methods. 

This revelation follows Sophos’ recent “Pacific Rim” reports, which detail a five-year campaign involving Chinese threat actors targeting network devices at an unprecedented scale. Among the identified tools, “Pigmy Goat” stands out as a rootkit crafted to resemble legitimate Sophos product files, making it challenging to detect. This strategy is known to use stealth by masking its identity within commonly named system files to evade basic detection protocols. “Pigmy Goat” enables threat actors to establish persistent, unauthorized access to the target’s network. Using the LD_PRELOAD environment variable, it embeds itself in the SSH daemon (sshd), allowing it to intercept and alter incoming connections. 

The malware seeks specific sequences called “magic bytes” to identify backdoor sessions, which it redirects through a Unix socket, thereby concealing its presence from standard security monitoring. Once a connection is established, it communicates with command and control (C2) servers over TLS. The malware cleverly mimics Fortinet’s FortiGate certificate, blending into networks where Fortinet devices are prevalent, to avoid suspicion. This backdoor offers threat actors multiple capabilities to monitor, control, and manipulate the network environment. Through commands from the C2, attackers can remotely open shell access, track network activity, adjust scheduled tasks, or even set up a SOCKS5 proxy, which helps them remain undetected while maintaining control over the network. These actions could allow unauthorized data access or further exploitation, posing significant threats to organizational cybersecurity. 

The NCSC report aligns “Pigmy Goat” with tactics used in “Castletap” malware, which cybersecurity firm Mandiant has linked to Chinese nation-state actors. The report’s insights reinforce concerns over the evolving sophistication in state-sponsored cyber tools aimed at infiltrating critical network infrastructure worldwide. Detection and prevention of “Pigmy Goat” are crucial to mitigating its impact. The NCSC report provides tools for identifying infection, including file hashes, YARA rules, and Snort rules, which can detect specific sequences and fake SSH handshakes associated with the malware. 

Additionally, monitoring for unusual files and behaviours, such as encrypted payloads in ICMP packets or the use of ‘LD_PRELOAD’ within the sshd process, can be effective. These insights empower network defenders to recognize early signs of compromise and respond swiftly, reinforcing defences against this sophisticated threat.

ATM Hacking Cyber Attacks Hidden Cobra Linux Malware Malware Attack North Korea North Korea Hackers

North Korean Hackers Develop Linux Variant of FASTCash Malware Targeting Financial Systems

 

A new Linux variant of FASTCash malware has surfaced, targeting the payment switch systems of financial institutions. North Korean hackers, linked to the Hidden Cobra group, have expanded their cyber arsenal to now include Ubuntu 22.04 LTS distributions. Previously, the malware targeted Windows and IBM AIX systems. These payment switches route transactions between ATMs and banks, and the malware intercepts ISO8583 messages, modifying transaction responses from “decline” to “approve.” This manipulation authorizes fraudulent cash withdrawals through money mules. The discovery, made by security researcher HaxRob, revealed the Linux variant’s ability to bypass security tools, as it was first submitted to VirusTotal in June 2023 with no detection. 

It operates by injecting a shared library into a running process on the payment switch server using the ‘ptrace’ system call. FASTCash’s history of ATM cash-out attacks dates back to 2016, with incidents stealing tens of millions of dollars across multiple countries. The U.S. Cyber Command in 2020 attributed these schemes to APT38, part of the Lazarus Group. North Korea’s involvement in global financial theft is well-documented, with the theft of over $1.3 billion linked to this malware and other campaigns. The Linux variant’s ability to evade standard defenses puts financial institutions at heightened risk. Its discovery emphasizes the evolving tactics of North Korean cyber actors, who are continually refining malware to expand their reach. 

HaxRob also noted a new Windows version of FASTCash, submitted in September 2024, demonstrating the ongoing development of this malware. To mitigate this growing threat, financial institutions must strengthen security around payment switch systems, implement real-time monitoring of unusual transaction patterns, and upgrade defenses to detect advanced attack techniques like FASTCash. 

As North Korean hackers continue to develop sophisticated malware variants, financial organizations must prioritize protecting against this persistent threat to prevent unauthorized cash withdrawals and financial losses.

CosmicBeetle Cyber Attacks ESET ESET Research Malware Attack ransomware attacks small business security Small Businesses Turkey

CosmicBeetle Exploits Vulnerabilities in Small Businesses Globally

 

CosmicBeetle is a cybercriminal group exploiting vulnerabilities in software commonly used by small and medium-sized businesses (SMBs) across Turkey, Spain, India, and South Africa. Their main tool, a custom ransomware called ScRansom, is still under development, leading to various issues in the encryption process. This sometimes leaves victims unable to recover their data, making the ransomware not only dangerous but also unpredictable. 

Based on analysis by Slovakian cybersecurity firm ESET, CosmicBeetle’s skills as malware developers are relatively immature. This inexperience has led to chaotic encryption schemes, with one victim’s machines being encrypted multiple times. Such issues complicate the decryption process, making it unreliable for victims to restore their data, even if they comply with ransom demands. Unlike well-established ransomware groups that focus on making the decryption process smoother to encourage payment, CosmicBeetle’s flawed approach undermines its effectiveness, leaving victims in a state of uncertainty. 

Interestingly, the group has attempted to boost its reputation by implying ties to the infamous LockBit group, a well-known and more sophisticated ransomware operation. However, these claims seem to be a tactic to appear more credible to their victims. CosmicBeetle has also joined the RansomHub affiliate program, which allows them to distribute third-party ransomware, likely as an attempt to strengthen their attack strategies. The group primarily targets outdated and unpatched software, especially in SMBs with limited cybersecurity infrastructure. They exploit known vulnerabilities in Veeam Backup & Replication and Microsoft Active Directory. 

While CosmicBeetle doesn’t specifically focus on SMBs, their choice of software vulnerabilities makes smaller organizations, which often lack robust patch management, easy targets. According to ESET, businesses in sectors such as manufacturing, pharmaceuticals, education, healthcare, and legal industries are particularly vulnerable. CosmicBeetle’s attacks are opportunistic, scanning for weak spots in various sectors where companies might not have stringent security measures in place. Turkey, in particular, has seen a high concentration of CosmicBeetle’s attacks, suggesting that the group may be operating from within the region. 

However, organizations in Spain, India, and South Africa have also been affected, illustrating the group’s global reach. CosmicBeetle’s focus on exploiting older vulnerabilities demonstrates the need for businesses to prioritize patching and updating their systems regularly. One key issue with CosmicBeetle’s operations is the immaturity of their ransomware development. Unlike more experienced cybercriminals, CosmicBeetle’s encryption tool is in a constant state of flux, making it unreliable for victims. While ESET has been able to verify that the decryption tool technically works, its rapid and frequent updates leave victims uncertain whether they can fully recover their data. To reduce the risk of falling victim to such attacks, SMBs must prioritize several cybersecurity measures. 

First and foremost, regular software updates and patch management are essential. Vulnerabilities in widely used platforms like Veeam Backup and Microsoft Active Directory must be addressed promptly. Businesses should also invest in employee cybersecurity training, emphasizing the importance of recognizing phishing attacks and suspicious links. In addition to these basic cybersecurity practices, companies should back up their data regularly and have robust incident response plans. Having a reliable backup strategy can mitigate the damage in the event of a ransomware attack, ensuring that data can be restored without paying the ransom. Companies should also invest in cybersecurity solutions that monitor for unusual network activity, providing early warning signs of potential breaches.

Babylon RAT Malaysia Government Cyberattack malware Malware Attack

Cyberattack Targets Malaysian Officials with Babylon RAT Malware

An investigation by the Cyble Research and Intelligence Lab (CRIL) has uncovered a sophisticated cyberattack aimed at Malaysian political figures and government officials. Initiated in July 2024, the attack utilizes fake ISO files to deploy Babylon RAT, a dangerous malware that allows cybercriminals to gain full control of infected devices and steal sensitive information. 

The ISO files look harmless but actually contain dangerous elements like a shortcut, a hidden PowerShell script, a harmful program, and a fake PDF. When someone opens the file, it quietly installs Babylon RAT on their computer. The Cyble Vision platform has linked this attack to previous malware campaigns involving Quasar RAT, suggesting a consistent strategy targeting high-profile individuals in Malaysia. 

The fake documents used in the attack often focus on political and governmental topics, including those related to the Majlis Amanah Rakyat (MARA), adding a layer of credibility to the malicious files. 

When a victim opens the ISO file, a hidden PowerShell script runs in the background, launching a decoy PDF while installing the malicious executable. This ensures that Babylon RAT is installed and can operate on the victim’s device. The malware enables the hacker to monitor keystrokes, steal passwords, track clipboard activity, and execute remote commands. 

Babylon RAT also persists on the device even after it is restarted. Babylon RAT, which first appeared on dark web forums in 2015, has been a staple in phishing attacks across multiple industries. It can spread across networks, initiate DDoS attacks, and act as a proxy to capture network traffic from compromised systems. 

CRIL researchers recommend implementing advanced email filters, keeping security systems updated, monitoring network activity for anomalies, and training staff to recognize phishing attempts to mitigate the risk of such attacks. Additionally, ensuring that software is always up to date with the latest security patches is essential for safeguarding against future threats.

Browser Security CyberCrime Data Breach Data Theft Malware Attack Malware Strains Online Security STYX

New Styx Stealer Malware Targets Browsers and Instant Messaging for Data Theft

 

A new malware strain known as Styx Stealer has recently emerged, posing a significant threat to online security. Discovered in April 2024, Styx Stealer primarily targets popular browsers based on the Chromium and Gecko engines, such as Chrome and Firefox. The malware is designed to pilfer a wide range of sensitive information from these browsers, including saved passwords, cookies, auto-fill data (which may include credit card details), cryptocurrency wallet information, system data like hardware specifics, external IP addresses, and even screenshots. 

The implications of such a broad data theft capability are alarming, as the stolen information could be used for identity theft, financial fraud, or even more targeted cyberattacks. Styx Stealer doesn’t stop at browsers. It also targets widely used instant messaging applications like Telegram and Discord. By compromising these platforms, the malware can gain access to users’ chats, potentially exposing sensitive conversations. This further exacerbates the threat, as the attackers could exploit this data to compromise the victim’s online identity or carry out social engineering attacks. The origins of Styx Stealer trace back to a Turkish cybercriminal who operates under the alias “Sty1x.” The malware is sold through Telegram or a dedicated website, with prices ranging from $75 per month to $350 for unlimited access. 

Interestingly, the malware’s discovery was aided by a critical mistake made by its developer. During the debugging process, the developer failed to implement proper operational security (OpSec) measures, inadvertently leaking sensitive data from their own computer to security researchers. This blunder not only exposed details about Styx Stealer’s capabilities and targets but also revealed the developer’s earnings and their connection to another notorious malware strain, Agent Tesla. Further forensic analysis uncovered a link between Sty1x and a Nigerian threat actor known by aliases such as Fucosreal and Mack_Sant. This individual had previously been involved in a campaign using Agent Tesla malware to target Chinese firms in various sectors. 

The connection between these two cybercriminals suggests potential collaboration, making Styx Stealer an even more formidable threat. Styx Stealer appears to be a derivative of the Phemedrone Stealer malware, inheriting core functionalities while introducing enhancements like auto-start and crypto-clipping features. These improvements make Styx Stealer more dangerous, increasing its potential to cause significant financial harm to its victims. The discovery of Styx Stealer highlights the ongoing evolution of cyber threats. Although the leak by the developer has likely disrupted Styx Stealer’s initial operations, it’s crucial to remain vigilant as cybercriminals adapt quickly.

RansomHub Deploys EDRKillShifter Malware to Disable Endpoint Detection Using BYOVD Attacks

 

Sophos security researchers have identified a new malware, dubbed EDRKillShifter, used by the RansomHub ransomware group to disable Endpoint Detection and Response (EDR) systems in attacks leveraging Bring Your Own Vulnerable Driver (BYOVD) techniques. This method involves deploying a legitimate but vulnerable driver on a target device to gain escalated privileges, disable security measures, and take control of the system. 

The technique has gained popularity among various threat actors, including both financially motivated ransomware groups and state-sponsored hackers. The EDRKillShifter malware was discovered during an investigation of a ransomware incident in May 2024. The attackers tried to use this tool to disable Sophos protection on a targeted computer but were unsuccessful due to the endpoint agent’s CryptoGuard feature, which prevented the ransomware executable from running. Sophos’ investigation revealed two different malware samples, both exploiting vulnerable drivers with proof-of-concept code available on GitHub. These drivers include RentDrv2 and ThreatFireMonitor, the latter being part of an obsolete system-monitoring package. 

The malware’s loader execution process follows a three-step procedure. Initially, the attacker launches the EDRKillShifter binary with a password string to decrypt and execute an embedded resource named BIN in memory. This code then unpacks and executes the final payload, which installs and exploits a vulnerable driver to elevate privileges and disable active EDR processes. Once the driver is loaded, the malware creates a service and enters an endless loop that continuously monitors and terminates processes matching names on a hardcoded target list. Interestingly, the EDRKillShifter variants discovered were compiled on computers with Russian localization, and they exploit legitimate but vulnerable drivers, using modified proof-of-concept exploits found on GitHub. 

Sophos suspects that the attackers adapted portions of these proofs-of-concept and ported the code to the Go programming language. To mitigate such threats, Sophos advises enabling tamper protection in endpoint security products, separating user and admin privileges to prevent the loading of vulnerable drivers, and keeping systems updated. Notably, Microsoft continually de-certifies signed drivers known to have been misused in previous attacks. Last year, Sophos identified another EDR-disabling malware, AuKill, which similarly exploited a vulnerable Process Explorer driver in Medusa Locker and LockBit ransomware attacks.

New Ransomware Threat: Hunters International Deploys SharpRhino RAT

 

In a troubling development for cybersecurity professionals, the Hunters International ransomware group has introduced a sophisticated new remote access trojan (RAT) called SharpRhino. This C#-based malware is specifically designed to target IT workers and breach corporate networks through a multi-stage attack process. The malware’s primary functions include achieving initial infection, elevating privileges on compromised systems, executing PowerShell commands, and ultimately deploying a ransomware payload. 

Recent findings from Quorum Cyber researchers reveal that SharpRhino is distributed via a malicious site masquerading as Angry IP Scanner, a legitimate networking tool widely used by IT professionals. The deceptive website uses typosquatting techniques to lure unsuspecting users into downloading the malware. This approach highlights a new tactic by Hunters International, aiming to exploit the trust IT workers place in well-known tools. The SharpRhino RAT operates through a digitally signed 32-bit installer named ‘ipscan-3.9.1-setup.exe.’ 

This installer contains a self-extracting, password-protected 7z archive filled with additional files necessary for the malware’s execution. Upon installation, SharpRhino modifies the Windows registry to ensure persistence on the compromised system and creates a shortcut to Microsoft.AnyKey.exe, which is normally a Microsoft Visual Studio binary but is abused here for malicious purposes. Additionally, the installer drops a file named ‘LogUpdate.bat,’ which executes PowerShell scripts to run the malware stealthily. To facilitate command and control (C2) operations, SharpRhino creates two directories: ‘C:\ProgramData\Microsoft: WindowsUpdater24’ and ‘LogUpdateWindows.’ 

These directories are used to manage communication between the malware and its operators. SharpRhino also includes hardcoded commands such as ‘delay’ to set the timer for the next POST request and ‘exit’ to terminate communication. This enables the malware to execute various dangerous actions, including launching PowerShell commands. For instance, Quorum Cyber researchers demonstrated the malware’s capability by launching the Windows calculator. Hunters International, which began operations in late 2023, has been associated with several high-profile ransomware attacks. Notable victims include U.S. Navy contractor Austal USA, Japanese optics giant Hoya, Integris Health, and the Fred Hutch Cancer Center. 

In 2024 alone, the group has claimed responsibility for 134 ransomware attacks, ranking it among the top ten most active ransomware operators globally. The deployment of SharpRhino through a fake website underscores Hunters International’s strategic focus on IT professionals, leveraging their reliance on familiar software to infiltrate corporate networks. To protect against such threats, users should exercise caution with search results and sponsored links, use ad blockers, and verify the authenticity of download sources. Implementing robust backup plans, network segmentation, and keeping software up-to-date are essential measures to mitigate the risk of ransomware attacks.

CloudFlare Cyber Attacks LNKs Malware Attack Malware Campaign Malware Trojan RATs

Abuse of Cloudflare Tunnel Service for Malware Campaigns Delivering RATs

 

Researchers have raised alarms over cybercriminals increasingly exploiting the Cloudflare Tunnel service in malware campaigns that predominantly distribute remote access trojans (RATs). This malicious activity, first detected in February, utilizes the TryCloudflare free service to disseminate multiple RATs, including AsyncRAT, GuLoader, VenomRAT, Remcos RAT, and Xworm. Cloudflare Tunnel service allows users to proxy traffic through an encrypted tunnel to access local services and servers over the internet without exposing IP addresses. 

This service is designed to offer added security and convenience by eliminating the need to open public inbound ports or set up VPN connections. With TryCloudflare, users can create temporary tunnels to local servers and test the service without requiring a Cloudflare account. However, threat actors have abused this feature to gain remote access to compromised systems while evading detection. A recent report from cybersecurity company Proofpoint observed that malware campaigns are targeting organizations in the law, finance, manufacturing, and technology sectors with malicious .LNK files hosted on the legitimate TryCloudflare domain. The attackers lure targets with tax-themed emails containing URLs or attachments leading to the LNK payload. 

Once launched, the payload runs BAT or CMD scripts that deploy PowerShell, culminating in the download of Python installers for the final payload. Proofpoint reported that an email distribution wave starting on July 11 sent out over 1,500 malicious messages, a significant increase from an earlier wave on May 28, which contained fewer than 50 messages. Hosting LNK files on Cloudflare offers several advantages to cybercriminals, including making the traffic appear legitimate due to Cloudflare’s reputation. 

Additionally, the TryCloudflare Tunnel feature provides anonymity, and the temporary nature of the subdomains makes it challenging for defenders to block them effectively. The use of Cloudflare’s service is not only free and reliable but also allows cybercriminals to avoid the costs associated with setting up their own infrastructure. 

By employing automation to evade blocks from Cloudflare, these criminals can use the tunnels for large-scale operations. A Cloudflare representative stated that the company immediately disables and takes down malicious tunnels as they are discovered or reported by third parties. Cloudflare has also implemented machine learning detections to better contain malicious activity and encourages security vendors to submit suspicious URLs for prompt action. 

In light of this increasing threat, it is crucial for organizations to remain vigilant and enhance their cybersecurity measures to defend against these sophisticated malware campaigns.

APK CloudSEK Cyber Attacks Hacking Attack Hacking WhatsApp Indian Cyber Security Malware Attack

Vietnamese Hackers Target Indian Users with Fake WhatsApp E-Challan Messages

 

A highly technical Android malware campaign orchestrated by Vietnamese hackers is currently targeting Indian users via fake traffic e-challan messages on WhatsApp. Researchers from CloudSEK, a cybersecurity firm, have identified this malware as part of the Wromba family. So far, it has infected over 4,400 devices, resulting in fraudulent transactions amounting to more than ₹16 lakh by just one scam operator. 

Vikas Kundu, a threat researcher at CloudSEK, reported that these scammers send messages impersonating Parivahan Sewa or Karnataka Police, tricking recipients into downloading a malicious app. Once the link in the WhatsApp message is clicked, it leads to the download of a harmful APK disguised as a legitimate application. This malware then requests excessive permissions, including access to contacts, phone calls, SMS messages, and even the ability to become the default messaging app. By intercepting OTPs and other sensitive messages, the attackers can log into victims’ e-commerce accounts, purchase gift cards, and redeem them undetected. 

Kundu explained that once the app is installed, it extracts all contacts from the infected device, enabling the scam to propagate further. Additionally, all SMS messages are forwarded to the attackers, allowing them access to various e-commerce and financial apps. The attackers cleverly use proxy IPs to avoid detection and maintain a low transaction profile. The report indicates that the attackers have accessed 271 unique gift cards, conducting transactions worth ₹16,31,000. 

Gujarat has been identified as the most affected region, followed by Karnataka. To guard against such malware threats, CloudSEK advises users to stay vigilant and adopt security best practices. These include installing apps only from trusted sources like the Google Play Store, regularly reviewing and limiting app permissions, maintaining updated systems, and enabling alerts for banking and sensitive services. This campaign underscores the growing sophistication of cyber threats and the importance of robust cybersecurity measures. 

As cybercriminals continue to develop new methods to exploit vulnerabilities, it is crucial for users to remain cautious and proactive in protecting their personal and financial information. Collaboration between cybersecurity firms and users is essential to effectively combat these evolving threats and safeguard against future incidents. By staying informed and adopting best practices, users can significantly reduce their risk of falling victim to such malicious campaigns.

Cyber Attacks data security ISP Malware Attack Service Provider South Korea User Privacy Webhards And Torrents

Korean ISP Accused of Installing Malware to Block Torrent Traffic

 

A major scandal has emerged in South Korea, where the internet service provider KT is accused of intentionally installing malware on the computers of 600,000 subscribers. This invasive action was reportedly designed to interfere with and block torrent traffic, a move driven by the financial pressures associated with the high bandwidth costs of torrenting. This revelation has significant implications for user privacy and the ethics of ISP practices. 

According to an investigative report by Korean outlet JBTC, KT—formerly known as Korea Telecom—took extreme measures to combat torrenting. Despite a decrease in filesharing traffic over the years, torrenting remains popular in South Korea, particularly through Web Hard Drive services (Webhard). These services use the BitTorrent-enabled ‘Grid System’ to keep files available, leading to significant bandwidth usage that caught the attention of ISPs like KT. KT, one of the largest ISPs in South Korea, had previously been involved in a court case in 2020 over throttling user traffic, citing network management costs. 

The court ruled in KT’s favor, but new reports indicate the company went beyond merely slowing downloads. Users of Webhard services began experiencing unexplainable errors and service outages around four years ago, all of whom were KT subscribers. JBTC’s investigation uncovered that KT had installed malware on these users’ computers, causing these disruptions. A dedicated team at KT, consisting of sections for malware development, distribution and operation, and wiretapping, allegedly planted malware to eavesdrop on subscribers and interfere with their file transfers. This malware not only limited torrent traffic but also allowed the ISP to access and alter data on users’ computers, raising serious legal and ethical concerns. 

The Gyeonggi Southern District Police Office, after conducting a search and seizure of KT’s data center and headquarters, believes the company may have violated the Communications Secrets Protection Act and the Information and Communications Network Act. In November last year, police identified 13 people of interest, including KT employees and employees of partner companies. 

The investigation is ongoing, with a supplementary probe continuing since last month. KT’s actions, ostensibly aimed at reducing network management costs, now appear likely to result in significant legal repercussions and potential financial losses. This case highlights the need for stricter regulatory oversight and transparency in ISP practices to protect consumer privacy and maintain trust.

AIVD Chinese Cyber Espionage Campaign Cyber Security Dutch intelligence FortiGate devices Fortnite Malware Attack

Dutch Intelligence Warns of Extensive Chinese Cyber-Espionage Campaign


 

The Dutch Military Intelligence and Security Service (MIVD) has issued a warning about the far-reaching consequences of a Chinese cyber-espionage operation disclosed earlier this year. According to the MIVD, the scale of this campaign is "much larger than previously known," impacting numerous systems across multiple sectors. 

In a joint report with the General Intelligence and Security Service (AIVD) released in February, the MIVD described how Chinese hackers exploited a critical vulnerability in FortiOS/FortiProxy (CVE-2022-42475). This remote code execution flaw was used over several months between 2022 and 2023 to deploy malware on susceptible Fortigate network security devices. During this "zero-day" period, about 14,000 devices were compromised. Targets included various Western governments, international organizations, and many companies within the defense industry. 

The malware, identified as the Coathanger remote access trojan (RAT), was detected on a network used by the Dutch Ministry of Defence for research and development (R&D) of unclassified projects. However, network segmentation prevented the attackers from spreading to other systems. The MIVD highlighted that this previously unknown malware strain could persist through system reboots and firmware upgrades. It was used by a Chinese state-sponsored hacking group in a political espionage campaign targeting the Netherlands and its allies. 

This persistent access allowed the state actor to maintain control over compromised systems even after security updates were applied. "The exact number of victims with malware installed is unknown," stated the MIVD. "However, the Dutch intelligence services and the NCSC believe that the state actor could potentially expand its access to hundreds of victims worldwide and engage in further actions such as data theft." Since February, the Dutch military intelligence service discovered that the Chinese threat group had accessed at least 20,000 FortiGate systems globally over a span of a few months in 2022 and 2023, beginning at least two months before Fortinet disclosed the vulnerability. 

The Coathanger malware's ability to intercept system calls to avoid detection and its resilience against firmware upgrades make it particularly difficult to remove. Fortinet disclosed in January 2023 that the CVE-2022-42475 vulnerability was exploited as a zero-day to target government organizations and related entities. The MIVD's findings mirror the characteristics of another Chinese hacking campaign that targeted unpatched SonicWall Secure Mobile Access (SMA) devices with cyber-espionage malware designed to withstand firmware updates. 

The revelations from Dutch intelligence underscore the increasing sophistication and persistence of state-sponsored cyber-espionage campaigns. As cyber threats continue to evolve, the importance of robust cybersecurity measures and vigilant monitoring becomes ever more critical to protect sensitive information and infrastructure from these advanced persistent threats.

ChatGPT Hallucinations Open Developers to Supply Chain Malware Attacks

Researchers have discovered a concerning vulnerability in ChatGPT that could potentially be exploited by attackers to propagate harmful code packages. This particular weakness stems from ChatGPT's tendency to provide inaccurate information, which could be leveraged to introduce malicious software and Trojans into trusted applications and code repositories such as npm, PyPI, GitHub, and various others. 

This represents a substantial threat to the software supply chain. In a recent blog post, researchers from Vulcan Cyber's Voyager18 research team have shed light on a concerning method employed by threat actors, known as "AI package hallucinations." This technique exploits ChatGPT's capability to generate recommendations, leading to the creation of seemingly legitimate code packages that contain malicious elements. 

Developers who interact with the chatbot may unknowingly download these packages and integrate them into their software, which can subsequently be widely distributed. This discovery highlights the potential risks associated with the misuse of ChatGPT and its impact on software security. 

What is AI- Hallucination? 

In the realm of artificial intelligence, the term "hallucination" refers to a response generated by AI that appears reasonable but falls short in terms of accuracy, bias, or outright falsehood. This phenomenon arises due to the nature of ChatGPT and similar large language models (LLMs) that form the foundation of generative AI platforms. 

When posed with questions, these models rely on information sourced from the vast expanse of the Internet, which includes various types of data such as sources, links, blogs, and statistics. However, the training data available to these models may not always be reliable or of the highest quality. Consequently, the AI's responses can be influenced by this imperfect training data, leading to hallucinations that do not align with factual information. 

In the blog post authored by Bar Lanyado, the lead researcher at Voyager18, he highlighted that LLMs such as ChatGPT possess extensive training and exposure to vast amounts of textual data. As a consequence, these models have the ability to generate responses that may appear plausible but are actually fictional. 

Furthermore, he said that LLMs have a tendency to extrapolate beyond their training, potentially leading to the production of responses that seem credible but lack accuracy. 

Researchers Conducted an Experiment Of An AI Hallucination 

In their demonstration, the researchers conducted an experiment utilizing ChatGPT 3.5 to validate their concept. They constructed a scenario where an attacker posed a coding problem to the platform, requesting a solution. As a response, ChatGPT generated a set of packages, including some that were non-existent, indicating they were not available within a reputable package repository. 

This practical demonstration served to illustrate how the platform could generate misleading and potentially malicious package recommendations. According to the researchers, the fabricated code packages produced by ChatGPT could serve as a novel avenue for attackers to distribute malicious software, bypassing conventional techniques like typosquatting or masquerading. 

By presenting these fabricated packages as genuine recommendations from ChatGPT, attackers can exploit the trust developers place in the platform's suggestions. Consequently, there is a significant risk of malicious code infiltrating legitimate applications and code repositories, thereby posing a major threat to the software supply chain. 

How To Detect Bad Code Libraries?

According to the researchers, detecting malicious packages can be challenging, especially when threat actors employ obfuscation techniques or create functional Trojan packages. However, developers can take preventive measures by thoroughly validating the libraries they download. It is crucial to ensure that these libraries not only perform their intended functions but also aren't cleverly disguised Trojans posing as legitimate packages, as highlighted by Lanyado. 

Risks Of the AI-Language Model 

Since its release in November, ChatGPT has gained popularity not only among users but also among threat actors who exploit it for cyberattacks. In the first half of 2023, security incidents have included scams targeting user credentials, theft of Chrome cookies through malicious ChatGPT extensions, and phishing campaigns utilizing ChatGPT as bait for malicious websites. 

While some experts argue the security risk may be exaggerated, the researchers emphasized that the rapid adoption of generative AI platforms like ChatGPT has indeed introduced potential security concerns due to their integration into daily professional activities and workload management.
