Trojanized npm Packages Distribute RedC2 4.0 Linux Backdoor Across Systems


In an investigation uncovered by cybersecurity researchers, 14 trojanized NPM packages have been masquerading as legitimate calendar modules and utility modules while secretly delivering a Linux backdoor powered by artificial intelligence (AI) known as RedC2 4.0. 


Upon importation of the malicious packages, TrendAI, Trend Micro's enterprise cybersecurity company, explains that they execute the payload bundled with the module without any installation hooks required. In the code, the embedded binary is located, permissions are changed to make it executable, and it is then launched as a detached background process. 

As a result, even a transitive dependency can trigger the backdoor when a compromised package is loaded. It is concealed under filenames such as math-core.bin and calc-math.dat that the malicious payload is concealed in order to prevent raising suspicion. Through the embedded Linux beacon, attackers are able to communicate with remote infrastructure and gain access to affected systems to conduct further malicious activities. 

RedC2 4.0 has been actively developed with capabilities extending beyond basic remote access. Along with interactive shell access and system reconnaissance, its Linux component facilitates data collection, including the theft of sensitive information such as SSH keys, through its Linux component. The comprehensive framework also encompasses file transfer, network visualization, host-to-host tunneling, and in-memory payload execution, highlighting the growing threat posed by malicious software packages. 

Malicious Packages Retain Legitimate Functionality

In spite of the fact that the compromised packages do not appear to be obviously malicious, they continue to provide the calendar and date-related functions described in their package descriptions. The malicious code, however, is concealed within the package structure, in which files such as math-core.bin, math-calc.bin, calc-math.dat, calc-cache.bin, calc.bin and calc-mapping.bin are listed as native components. 

There are two types of files stored within the dist/ directory: either directly under the dist/ directory or in dist/internal/ directory. Even though the names of these packages differ, they contain the RedShell Linux beacon that is associated with RedC2 4.0. The package entry file, dist/index.mjs, serves as a loader. It re-exports the valid date utilities while simultaneously initiating the embedded implant. By doing so, the malicious component does not require an installation hook or specific function call to execute. 

RedShell Gives Attackers Remote Access

RedShell beacons establish communication with remote command-and-control servers once they become active and register compromised systems. Prior to entering a command-processing LO, they collect basic information about the host. 

Through /bin/sh, the Linux beacon provides an interactive shell and allows for a wide range of system operations, including system discovery, file management, collection of data, and execution of commands. This implant also has the capability of searching for sensitive information, including SSH keys and browser credentials. In addition to persistence and in-memory ELF execution, it also supports SOCKS5 proxying. 

The network pivoting capabilities further enable an attacker to use compromised systems as an entry point into other environments. This version of RedC2 4.0 also provides similar features across macOS and Windows. The framework provides file operations, host and network reconnaissance, enumeration of users, and data collection. 

The Windows component also offers capabilities such as bypassing UAC, tampering with security tools, and lateral movement. 

RedC2 Framework Adds AI Assisted Operations

For Windows, Linux, and Mac OS, RedC2 4.0 is presented as a cross-platform command-and-control framework. As of August 2025, the framework has been actively developing, with version 3.0 appearing in January 2026 and version 4.0 released in June. In addition to the RedShell Linux beacon, the latest version offers a comprehensive set of post-exploitation functionality. 

There are several features in this framework, including access to terminals, file transfers, staged payload delivery, multi-beacon management, network visualisation, host-to-host tunnelling, and execution of BOFs, .NET assemblies and shellcode in memory. 

As an important addition, Red Agent is an artificial intelligence-assisted component with a large language model. It allows operators to describe tasks in natural language and have these instructions translated into beacon commands by the framework. By incorporating this feature, operations such as network reconnaissance and credential collection can be simplified. Moreover, it decreases the technical knowledge required to operate more complex framework functions. 

Supply Chain Risks Extend Beyond npm

A wider pattern of attacks is being observed against software ecosystems as a result of the incident. In recent years, development teams have increasingly relied on third-party packages, which often include binaries and transitive dependencies that are not visible to developers. 

A package can appear useful and maintain normal behavior while carrying a separate native payload even though it has legitimate functionality present, making it particularly difficult to detect such attacks during routine code reviews. As part of the RedC2 campaign, three legitimate Rust crates were also subjected to a recent supply chain attack. These packages have been modified in order to include a malicious dependency capable of executing malware during cargo builds. 

In addition to targeting multiple development ecosystems rather than focusing exclusively on NPM, the incidents reinforced the need for tighter dependency controls for development and infrastructure teams. When possible, it is recommended that package versions be pinned and dependencies and embedded binaries be reviewed before entering production environments. 

It is possible to detect suspicious activity by monitoring unexpected process creation and outbound network connections from build systems. As the number of malicious packages carrying backdoors continues to increase, software supply chains continue to be an important entry point for malicious entities. By including AI-assisted functionality to frameworks such as RedC2, operational capabilities are further improved following an initial compromise.

Ultra-Wealthy Turn to Premium Services to Erase Their Digital Footprints

 

For the ultra-wealthy, protecting personal information is increasingly becoming a premium service. High-net-worth individuals and corporations are paying specialized privacy firms to track down and remove personally identifiable information (PII) from search engines, data-broker databases and even the dark web.

Unlike automated privacy tools, these high-end services combine data removal with continuous monitoring and manual audits designed to reduce both online exposure and physical security threats.

Consumer-focused services such as DeleteMe, Incogni and Google’s free PII removal tool can help limit exposure, but their reach remains restricted. Data brokers often use measures to prevent automated deletion requests. “insert something like a captcha to ensure that a bot can’t come in and wipe out their database,” Tom Aldrich, chief operating officer of digital exposure reduction firm 360 Privacy, told Observer.

Aldrich said his company, which works with 32 Fortune 100 companies, recently took on a wealthy client who had previously used an automated service. The firm discovered 62 profiles belonging to the individual across hundreds of data aggregation platforms. “We found 62 different profiles on them across hundreds of data aggregator sources,” said Aldrich, who added that 93 percent of those profiles included non-public information and could be removed.

Digital exposure is becoming a physical security concern

Security experts increasingly warn that information available online can create risks in the physical world. Threats against senior executives have risen steadily over the past two decades, with attacks in 2025 more than doubling compared with the previous year.

“Physical and digital can no longer be separate,” Brian Hill, field chief information security officer at personal cybersecurity firm BlackCloak, which serves corporate executives and high-net-worth individuals, told Observer.

The connection became particularly evident in the case of Vance Boelter, the Minnesota gunman sentenced in July to two consecutive life sentences plus 40 years for killing Democratic lawmakers in 2025. Boelter reportedly used data aggregator websites to identify his victims.

Growing concerns around executive safety have also pushed security spending higher. The median security expenditure for executives at S&P 500 companies increased 37.8 percent between 2024 and 2025. During the same period, S&P 500 CEOs earned an average annual compensation of $18.9 million.

Meta was among the biggest spenders, allocating more than $25 million toward physical and digital security for CEO Mark Zuckerberg.

For family offices, celebrities and high-net-worth clients, BlackCloak's services can cost between $10,000 and roughly $200,000 annually. Enterprise contracts covering executives, board members and founders can reach as much as $600,000 per year.

A growing market for digital privacy

The expanding digital footprint of consumers has created an entire economy around personal-data protection. Data brokers collect and sell personal information to third parties, contributing to a North American data-broker market estimated at $40 billion.

Removing such information is often difficult and labor-intensive, increasing demand for specialized providers that can continuously identify and eliminate exposed data.

Only California, Oregon, Texas and Vermont currently require data brokers to identify themselves through state registries. More than 4,000 data brokers are estimated to operate across the U.S., with many outside the reach of comprehensive regulation. California alone has 545 registered data brokers.

Premium privacy firms typically remove information from publicly accessible websites while also monitoring the dark web and strengthening security across users' accounts and devices. Connected household technology, including security cameras, may also be included in these security assessments.

Still, complete digital anonymity is difficult to achieve. “Reducing your digital footprint to zero is virtually impossible,” said Hill. “Our goal is anywhere from 70–90 percent removal of data.”

Certain public records, including newspaper archives and campaign donation records, can also remain difficult or impossible to erase.

Affordable services remain an option

While high-end privacy protection is increasingly being adopted by wealthy individuals and corporations, more affordable services can still help ordinary consumers reduce their exposure.

Aura, for example, offers automated data removal alongside other digital safety services for families at $32 per month. “As data breaches continue, data brokers expand, and A.I. makes it easier to exploit personal information, more people are looking for ways to reduce their digital footprint and regain control of their privacy,” Tom Clayton, president and chief operating officer of Aura, told Observer.

Despite the growing number of services available, adoption remains relatively low. Only 6 percent of American adults use data-removal services, while more than half do not know such services exist.

Smaller businesses are increasingly vulnerable as well. “The attackers are…going after the small companies, the local family businesses. They’re now becoming the targets because they’re the easy ones,” Hill said.

Executives and their families continue to face particular risks. According to a 2025 report from BlackCloak and the Ponemon Institute, 51 percent of security leaders said cyberattacks had targeted the personal accounts of executives or their family members.

As personal and professional digital lives become increasingly intertwined, conventional corporate security teams may not fully protect executives' personal information. That gap is helping drive demand for specialized privacy and cybersecurity providers.

Artificial intelligence and emerging technologies could make the problem even more challenging. “With a lot of this technology,” said Hill about A.I. and quantum computing, “you’re going to see a lot more data collection, and it’s going to be easier to go after the people that don’t set up an LLC or trust because they just don’t think they need to.”

Here's Why Skipping Windows Updates Puts Your PC at Risk

 

Skipping Windows updates may seem harmless, especially when an update requires a restart or temporarily changes familiar settings. Many users postpone updates because they fear slower performance, bugs, or interruptions during work. However, Windows updates are not limited to new features and interface changes. They also contain important security patches that repair weaknesses discovered by Microsoft, cybersecurity researchers, customers, and attackers. When these updates are ignored, a computer can remain exposed to vulnerabilities that criminals already understand how to exploit. 

Once Microsoft releases a patch, attackers can study it to identify the weakness it fixes. They can then search for computers that have not installed the update and target them with malware or other attacks. An unpatched Windows system may face threats such as remote code execution, privilege escalation, ransomware, credential theft, and boot-level compromise. These attacks do not always produce immediate warning signs. A computer may appear to work normally while malicious software quietly steals information, monitors activity, or prepares a larger attack. 

PrintNightmare, identified as CVE-2021-34527, demonstrates how quickly a Windows vulnerability can become dangerous. After public proof-of-concept exploits began circulating in 2021, Microsoft issued emergency updates because exploitation had already been detected. Users who delayed installing the fixes increased the risk that attackers could gain control through the Windows Print Spooler service. The incident showed that waiting for a convenient time to update can be risky when details about a vulnerability and its exploit are already publicly available. 

The WannaCry ransomware outbreak provides an even more dramatic example. Microsoft had released a patch for the exploited SMB vulnerability in March 2017, but many organizations and individuals had not installed it or were still using older, unsupported Windows versions. When WannaCry spread in May, it affected more than 300,000 computers across 150 countries, disrupting hospitals, factories, businesses, and other services. The outbreak proved that a single neglected update can allow malware to spread rapidly across connected networks. 

The safest approach is to install Windows updates as soon as practical, while choosing an appropriate time for the restart. Users should also maintain backups, use reputable security software, and avoid keeping unsupported Windows versions connected directly to the internet. Although updates can occasionally cause inconvenience, a short installation and reboot are usually far less costly than recovering from ransomware, stolen credentials, or a compromised system. Keeping Windows updated is therefore one of the simplest and most effective ways to reduce everyday cybersecurity risks.

Amazon Handbook Warns About Online Shopping and Delivery Box Scams

 

Online shopping has become the new norm with millions of people shopping through online platforms like Amazon and Flipkart. Unfortunately, online shopping comes with its own set of risks as frauds and scammers always look for ways to take advantage of people who shop online. Fake websites, false delivery packages, payment frauds and ‘too-good-to-be-true’ deals are some of the methods used by fraudsters. 

Amazon’s new consumer handbook created by Safer Internet India aims to provide online shoppers with information that can help protect them against online frauds and scams. The book highlights some of the key online shopping scams that are currently affecting shoppers. It provides a vital reminder that shopping online involves many risks and consumers need to be wary of the various online scams that they might stumble upon.  

According to the article, one of the scams highlighted in the book is the Delivery Box scam. When customers shop on e-commerce sites like Amazon or Flipkart, the products they purchase usually come in a box with delivery information. According to the new book, the delivery box usually has the customer’s personal information including their names, email address, telephone number and sometimes the item that has been delivered. After removing the item from the box, many customers usually throw away the box without removing the personal information on the delivery label.

According to the report, fraudsters usually collect discarded delivery boxes with personal information and use the information to contact the customers. The fraudster pretends to be a delivery executive and informs the customer that they need their feedback on the product they purchased. The fraudster further explains that the customer stands to receive a discount of 10% or more if they click on a link provided to give feedback. According to the article, the link provided by the scammer contains malware which infiltrates the customer’s device and gathers private information including banking credentials. 

The article informs consumers that they should consider using a sharp object like a knife to scratch off personal information on delivery packaging before throwing the box away. Alternatively, they could use a permanent marker to mask vital information on the delivery box. The Identity Protection Roller Stamp ID could also be considered to protect personal information. 

Moreover, consumers should be wary of random discount offers and avoid clicking on links provided by unknown individuals or entities. The consumer handbook and warning on Delivery Box scams can help shoppers identify online frauds and protect themselves from falling victim to online scams.

RingCentral Breach Exposes Personal Data of 1.6 Million Accounts


 

An attack on RingCentral, which was targeted at social engineering, has led to a data breach that could have exposed personal information of around 1.6 million individuals. In July, RingCentral detected the unauthorized activity during a campaign. The company said it immediately responded to the incident and launched an investigation with the assistance of an external forensic firm in order to contain the unauthorized activity. 

In light of the remediation measures implemented, RingCentral has not detected any further unauthorized activity. In addition, RingCentral clarified that only a limited number of its customers were affected by the incident and that those who were potentially affected were contacted directly. Furthermore, the company clarified that its services remain operational, and that its core platform was unharmed. 

Despite the lack of identification of the threat actor by the company, the ShinyHunters extortion group reportedly listed RingCentral on its Tor-based leak site in late July. As a result of the group's claim that they obtained over 623GB of data, there is further concern about the size of the attack. After investigating the leaked data, Have I Been Pwned confirmed that the dataset contains information associated with approximately 1.6 million accounts, including names, email addresses, telephone numbers, and physical addresses. 

The disclosure supports ShinyHunters' claims, even though RingCentral has not publicly attributed the incident to the group or provided details concerning how the attackers gained access to their system. A broader pattern of data theft attacks has been claimed by ShinyHunters against customers of major cloud and SaaS providers, including Salesforce and Snowflake, as well as the incident described above. This group has targeted third-party platforms and integrations increasingly, using stolen corporate data to extort companies. 

A recent lawsuit against Oracle PeopleSoft underscores the extent and persistence of the data theft operations of the organization. It has been possible for independent researchers to assess the scope of the exposure after publishing the 280GB archive. Has I Been Pwned reported approximately 1.6 million unique email addresses in the leaked data, along with names, telephone numbers, and physical addresses. 

A RingCentral representative has not independently verified the attacker's claims or disclosed the number of people affected. The incident also illustrates the effectiveness of voice-based social engineering, a strategy increasingly associated with ShinyHunters. Threat actors conduct these attacks by impersonating IT personnel and leading employees to a convincing login page with the intent of capturing passwords and authentication codes. It is possible that conventional one-time-password MFA will not be sufficient to prevent account compromise due to the attack's reliance on manipulating the employee rather than breaking the underlying security technology. 

As a result, security experts are increasingly recommending phishing-resistant methods, such as FIDO2 passkeys. These passkeys bind authentication to a legitimate website, preventing credentials from being regenerated through a fraudulent website. 

The details of the authentication method used by the compromised account have not been disclosed, nor have any controls been implemented to prevent phishing attacks. It is imperative to note that exposing names, phone numbers and physical addresses poses a risk beyond the initial compromise. These disclosures can provide attackers with sufficient context to carry out further impersonations and phishing attempts in a convincing manner. 

ShinyHunters has continued to focus on data theft and extortion rather than traditional ransomware, as demonstrated by the RingCentral incident, which illustrates how a single successful social engineering attack can lead to a much larger privacy and security issue as it progresses. 

The RingCentral incident has raised several questions, primarily regarding the extent of the exposure and the means by which the accounts were compromised. Have I Been Pwned has identified approximately 1.6 million email addresses in the leaked dataset, whereas RingCentral has described the customer base as limited. 

To determine the full impact of this incident, it is critical to reconcile those figures, along with more information about the compromised accounts, in order to determine the full extent. In organizations using RingCentral or similar cloud communication platforms, it is critical to establish strong defenses against social engineering at the earliest opportunity. During security awareness training, attention should be paid to suspicious calls, credential-harvesting websites, and requests for authentication codes. 

Organizations handling sensitive or regulated information should assess notification and compliance requirements for phishing attacks, multiple factor authentication, credential resets for potentially compromised accounts, and monitoring for follow-up phishing attacks and business email compromises. A wider question is raised by the incident about security at the intersection of technology and individuals. 

Even organizations with well-established security controls can be exposed if an attacker convinces an employee to bypass these controls. The breach thus serves as a reminder to RingCentral customers that safeguarding communication systems requires not only strong technical controls, but also preparation for social engineering tactics that are becoming increasingly convincing in order to target employees.

New 'Zapscape' Linux KVM Vulnerability Opens Path for Privileged Guest-to-Host Escape

 



A newly disclosed vulnerability in Linux's Kernel-based Virtual Machine (KVM) could allow an attacker with kernel-level control inside a nested virtual machine to break out of virtualization boundaries and execute code on the underlying host system under specific conditions.

Tracked as CVE-2026-64561 and dubbed Zapscape, the flaw affects KVM's x86 shadow memory management unit (MMU), a core component responsible for maintaining shadow page tables that translate memory between guest virtual machines and the host. Security researcher Hyunwoo Kim, who identified and disclosed the issue, demonstrated that the vulnerability can be leveraged to execute commands on the host with root privileges.

The issue has been addressed upstream, and administrators operating KVM environments that expose nested virtualization to untrusted virtual machines are advised to deploy patched kernel releases or vendor packages containing the backported fix.

Unlike conventional virtualization deployments where guest systems operate in isolation from the host, nested virtualization allows a virtual machine to function as a hypervisor itself. In this configuration, an L1 guest can create and manage additional virtual machines, commonly referred to as L2 guests. While this capability is widely used for cloud infrastructure testing, development environments, virtualization research, and continuous integration workloads, it also introduces additional complexity into memory management, making implementation flaws particularly impactful.

Zapscape requires an attacker to already possess kernel-level privileges inside an L1 guest, which generally translates to root access within that virtual machine. On Intel-based systems, exploitation additionally depends on exposing both Extended Page Table (EPT) page-walk lengths four and five to the L1 guest. AMD platforms do not impose this additional requirement.

At the heart of the vulnerability is a flaw in the ordering of stale-root validation within KVM's shadow MMU bookkeeping. The weakness results in a use-after-free condition, a class of memory safety bug in which software continues interacting with memory after it has already been released.

According to Kim's technical analysis, the issue occurs while KVM is servicing guest-triggered page faults. During this process, KVM may reclaim shadow MMU pages to free memory resources. That reclamation can invalidate the shadow MMU root page currently being used by the ongoing page-fault handling routine. However, because the fault-handling path fails to verify that the root remains valid after the reclamation step, execution continues using an object that has already become stale.

The researcher explained that the vulnerability originates within KVM's recursive "zap" path, which is responsible for reclaiming shadow MMU pages. Before additional MMU pages are made available, KVM performs an initial stale-root validation. The problem arises because the subsequent reclamation process can invalidate that same root after the check has already completed. Rather than restarting with a fresh and valid root, KVM proceeds to construct new child shadow pages beneath the invalid parent.

Those newly created child pages inherit the parent's invalid state while simultaneously being inserted into KVM's active MMU page list. During later cleanup operations, the same list entry can become attached to multiple linked lists simultaneously. Eventually, the affected page may be freed even though stale references continue pointing to it, leaving behind a dangling pointer and enabling writes to memory that should no longer be accessible.

Such memory corruption primitives can provide the foundation for privilege escalation and virtualization escape techniques, particularly when an attacker already controls a privileged guest operating system.

To demonstrate the vulnerability, Kim released a public proof-of-concept that exploits the bug to create a root-owned file named /Zapscape on the vulnerable Linux host, illustrating successful code execution beyond the guest boundary.

The proof-of-concept was developed against AMD nested virtualization using Secure Virtual Machine (SVM) and Nested Page Tables (NPT) on Linux 7.1.3. For safe experimentation, Kim recommends running the demonstration under QEMU's Tiny Code Generator (TCG) mode. However, the researcher emphasized that QEMU itself is not affected by the vulnerability. Instead, the flaw resides entirely within the Linux kernel's KVM implementation and can be triggered independently of QEMU's device emulation.

Although exploit code is publicly available, Kim cautioned that the demonstration should not be interpreted as an immediately deployable attack against production cloud infrastructure. In its current form, the proof-of-concept requires additional engineering before it could be adapted for real-world environments. Among other changes, portions of the L1 guest activity would need to be moved into a guest kernel module, while the exploit would also require customization for the target host's kernel configuration and memory management backend.

At the time of disclosure, no evidence had emerged indicating that CVE-2026-64561 had been exploited in active attacks.

The National Vulnerability Database lists Linux kernel versions beginning with 5.9 as affected until fixed stable releases became available, including versions 6.6.148, 6.12.101, 6.18.42, 7.1.6, and 7.2-rc5.

Security advisories note that administrators should not rely solely on upstream version numbers when assessing exposure. Many enterprise Linux distributions routinely backport security fixes into existing kernel packages without rebasing to newer upstream releases, making vendor advisories the authoritative source for determining whether individual systems have received the necessary patches.

Red Hat assigned the vulnerability a preliminary CVSS score of 7.0 and categorized it under CWE-825: Expired Pointer Dereference, reflecting the use-after-free behavior underlying the flaw.

Package availability also varies across Linux distributions. As of August 6, Debian's security tracker listed kernel packages for bullseye, bookworm, trixie, and forky, including their security repositories, as vulnerable, while sid had already incorporated the fix beginning with version 7.1.6-1.

The coordinated disclosure followed a structured timeline spanning several weeks. Kim privately reported the vulnerability to security@kernel.org on July 11, 2026. A corrective patch was proposed and merged on July 21 before being shared with the linux-distros security mailing list on August 1 under a five-day embargo. The vulnerability subsequently received the identifier CVE-2026-64561 on August 4, with public disclosure taking place on August 6.

The upstream patch, merged as commit 2abd5287f083, modifies KVM's page-fault handling sequence by moving the stale-root validation until after make_mmu_pages_available() completes. If memory reclamation invalidates the current shadow MMU root, KVM now abandons the active page-fault operation and restarts it using RET_PF_RETRY, preventing further memory mappings from being created beneath an invalid root and eliminating the conditions that produced the use-after-free.

Zapscape marks the latest addition to Kim's ongoing security research into Linux virtualization. Earlier this year, the researcher disclosed Januscape (CVE-2026-53359), which affected KVM/x86's shadow MMU, and ITScape (CVE-2026-46316), a separate guest escape vulnerability impacting KVM on Arm64 systems. Together, the disclosures continue to draw attention to the security challenges involved in protecting complex virtualization infrastructure that underpins modern cloud and enterprise computing environments.

Crypto Protocols Lose $35M in Coordinated Attacks

 

In a alarming six-hour window on July 23, 2026, Bitcoin- and Ethereum-linked protocols suffered multiple exploits draining over $35 million in combined losses. The attacks targeted cross-chain bridges and expansion networks, revealing persistent vulnerabilities in operational controls rather than fundamental cryptographic failures. 

The most severe incident struck the Verus blockchain's Ethereum bridge, where attackers exploited a logic flaw to trigger unbacked payouts on the Ethereum side. Blockaid security researchers detected the exploit early Thursday, with approximately $7.54 million siphoned in ether, tokenized bitcoin, and stablecoins including USDC, USDT, EURC, MKR, and scrvUSD. Disturbingly, this represented a repeat offense: the same bridge contract and entry path had been compromised in May with $11.5 million lost, after which the attacker returned most funds for a bounty before Verus redeposited recovered money only to be drained again two weeks later. 

B² network and other victims

B² Network, a Bitcoin scaling solution designed to reduce transaction costs and increase speed, fell victim when an attacker gained unauthorized upgrade powers over its token staking contract during Asian trading hours. Lookonchain tracked around $3.86 million in B2 tokens sold and converted to ether and stablecoins before being moved off-chain. B² responded by pausing staking services and pledging full compensation for affected users. Additional protocols including AFX and Balance also reported losses within the 24-hour period, bringing the total number of exploited teams to four. 

 Common Attack Vector Emerges All incidents shared a critical characteristic: none broke underlying cryptography. Instead, each attack succeeded through either logical bugs—where code executed as written but rules permitted fund extraction—or compromised administrative keys granting attackers control they should never have possessed. This pattern underscores how operational weaknesses, not mathematical vulnerabilities, remain the primary threat to cross-chain infrastructure. 

The Verus protocol's total value locked illustrates the human cost of repeated breaches. Starting 2025 with nearly $100 million according to DefiLlama, Verus now holds approximately $9 million—a gradual decline punctuated by this week's fresh drop. As security firms like Peckshield and BlockAid sharpen their detection tools, the frequency of such exploits highlights the urgent need for rigorous audit practices and key management protocols across the decentralized finance ecosystem.

OpenAI Says AI Agent Breached Hugging Face During Cybersecurity Test

 



OpenAI has disclosed that one of its advanced artificial intelligence agents autonomously breached the boundaries of a controlled cybersecurity evaluation and accessed parts of AI platform Hugging Face's infrastructure, prompting a joint investigation into what both organizations describe as a previously unseen security event.

The incident occurred during an internal assessment designed to measure the cyber capabilities of OpenAI's latest AI agents. According to the company, the models were operating inside a testing environment where certain safety restrictions had been deliberately relaxed to evaluate their ability to complete complex security tasks. During the evaluation, the AI identified weaknesses in the testing environment, escaped its intended confines, and independently attempted to obtain additional information by interacting with external systems.

That activity ultimately led the agent to Hugging Face, a widely used platform that hosts open-source AI models, datasets, and machine learning tools. OpenAI said the model gained access to portions of Hugging Face's internal infrastructure before the activity was detected and contained in collaboration with the platform's security team.

The companies have described the event as unprecedented because the sequence of actions was carried out autonomously after the AI received its initial objective, without operators directing each subsequent step.

Hugging Face Chief Executive Officer Clement Delangue called the incident "mind-blowing" in a post on X, saying the investigation remains ongoing and may represent one of the first known cases of an autonomous AI agent independently conducting a real-world cyber intrusion.

OpenAI said it is working with Hugging Face to determine exactly how the model escaped the evaluation environment and which technical weaknesses enabled the intrusion. The company added that lessons from the investigation will inform future safeguards for advanced AI evaluations.

According to Hugging Face, the intrusion affected parts of its internal systems rather than its public repositories. The company said investigators are continuing to determine whether any customer or partner information was exposed and will notify affected organizations if necessary. Since the incident, Hugging Face has closed the identified vulnerabilities, rebuilt impacted infrastructure, and rotated relevant credentials as part of its remediation efforts.

The company also emphasized that there is no evidence that publicly available AI models, datasets, or software packages hosted on the platform were modified during the incident.

Security researchers say the event illustrates both the growing capabilities of autonomous AI systems and the importance of robust containment mechanisms during frontier AI testing.

Gina Neff, executive director of the Minderoo Centre for Technology and Democracy at the University of Cambridge, said AI evaluations are typically conducted inside isolated environments, commonly referred to as sandboxes, where researchers can safely observe model behavior. Based on the available information, she suggested the evaluation environment did not provide sufficient isolation, allowing the AI agent to exploit weaknesses in the testing infrastructure itself rather than remaining confined to the intended experiment.

Neil Lawrence, Professor of Machine Learning at the University of Cambridge, described the behavior as technically impressive while cautioning that it remains within the capabilities demonstrated by today's most advanced frontier models. He also noted that companies developing increasingly capable AI systems face growing commercial pressure to demonstrate their technological progress amid intensifying competition across the AI industry.

The incident has also drawn the attention of UK authorities. A government spokesperson said the UK's AI Security Institute is studying the behavior observed during the evaluation and continues collaborating with OpenAI and other leading AI developers to strengthen safety standards for advanced models. The government also encouraged organizations to strengthen their cybersecurity posture through established frameworks such as the Cyber Essentials certification scheme.

Cybersecurity professionals say the incident reinforces concerns that autonomous offensive AI capabilities are advancing faster than many organizations' defensive preparedness.

Spencer Starkey, an executive at cybersecurity firm SonicWall, said organizations should treat cyber resilience as a core operational priority as attackers increasingly leverage automation and artificial intelligence to conduct attacks at machine speed.

Travis Lelle, Principal Security Engineer at Guidepoint Security, described the disclosure as a sobering development for the cybersecurity community. He noted that offensive AI systems often operate with fewer practical constraints, while many defensive AI tools remain intentionally restricted by safety guardrails, creating an imbalance that defenders will need to address.

Jake Moore, Global Cybersecurity Advisor at ESET, said the disclosure may also carry strategic implications beyond its technical significance. He suggested the announcement arrives as competition among leading AI developers intensifies, particularly following Anthropic's recent advances and the unveiling of new frontier AI models by other companies, including Chinese startup Moonshot AI.

Beyond the immediate investigation, the incident is expected to influence how AI companies design future cybersecurity evaluations. Researchers increasingly argue that testing environments for highly capable AI systems must assume that models will actively search for opportunities to escape containment rather than simply complete assigned tasks.

As AI systems become capable of independently identifying vulnerabilities, adapting their strategies, and chaining together multiple attack techniques without continuous human guidance, organizations may need to deploy equally sophisticated AI-assisted defensive technologies capable of detecting and responding to threats at comparable speed.

OpenAI and Hugging Face said their joint investigation remains ongoing, with both organizations expected to publish additional technical findings and recommendations as they continue analyzing the incident.

Ransomware Attacks Become More Sophisticated as Experts Debate Effectiveness of Payment Bans

 

iNearly half of organizations hit by ransomware attacks end up paying cybercriminals to regain access to their data or systems, while the average ransom demand continues to rise, according to Sophos' 2025 cybersecurity research. As governments move to curb ransom payments, cybersecurity experts remain divided over whether outright bans will reduce cybercrime or create new risks.

Countries are increasingly exploring restrictions on ransom payments. In the UK, the government is progressing plans to prevent public sector organizations and operators of critical national infrastructure—including the National Health Service (NHS), local councils and schools—from paying cybercriminals following ransomware incidents.

The proposed restrictions come as ransomware attacks have become significantly more advanced, with threat actors increasingly targeting vulnerable small and medium-sized businesses through sophisticated techniques.

“In 2026, the ransomware landscape has evolved into a highly sophisticated, corporate-style ecosystem,” says Haydn Brooks, chief executive of supply chain security group Risk Ledger. “While ransomware groups operate like smart B2B operations to ensure data return, the legal and sanction risks of paying are at an all-time high.”

The rapid adoption of malicious artificial intelligence (AI) tools such as WormGPT, FraudGPT and BruteForceAI has further accelerated ransomware operations. According to Dave Spillane, systems engineering director at Fortinet, confirmed ransomware victims surged by 389% year-on-year in 2025, increasing from nearly 1,600 cases in 2024 to 7,831 worldwide.

“In the time it would have previously taken to commit one ransomware attack, hackers can now target four separate organizations simultaneously,” he says.

“The cost per attack has dramatically decreased, commoditizing sophisticated attacks, whereas the cost to defend is increasing,” agrees Shashi Kiran, chief marketing officer of tech group Nile. “What required nation states earlier can be accomplished by individuals with half-baked skills leveraging the power of AI.”

Despite the growing threat, opinions remain sharply divided on whether organizations should ever pay ransom demands.

Jim Walter, senior threat researcher at SentinelOne, believes ransom payments only strengthen cybercriminal operations.

“Paying extortive threat actors only strengthens the ecosystem and the entities that enable it,” he says, warning that cybercriminals cannot be relied upon to permanently delete stolen information after receiving payment.

He further cautions that repeated extortion attempts and continued misuse of stolen data are common outcomes. “Paying absolutely does not guarantee recovery, it actually encourages further crime and extortion.”

However, some experts argue that blanket payment bans fail to account for complex real-world scenarios.

“Our concern with a ban is what happens when a payment ban is in place but data recovery is not feasible,” says Andy Maus, head of cyber recovery services at DriveSavers, a company specializing in hard drive data recovery. “Situations are almost always more nuanced than a ban accounts for.”

For operators of critical national infrastructure, such as water utilities or power providers, prolonged service disruptions could have severe consequences if systems cannot be restored and ransom payments are prohibited.

“We can see how payment bans make sense where data recovery is a viable alternative; however, blanket prohibition has the potential to cause more harm than it prevents,” Maus says.

He also points to previous statewide payment bans introduced in North Carolina and Florida during 2021 and 2022, stating that “neither ban appears to have materially deterred criminal activity.”

Haydn Brooks believes that limiting ransom payments by public institutions could redirect cybercriminal activity toward private businesses.

If public organizations are prohibited from making payments, “the cyber insurance market will inevitably shift,” he adds, “excluding these payouts and driving premiums sky-high as the costs dwarf the original ransom demands.”

As ransomware incidents continue to increase, a growing ecosystem of specialized service providers—including ransom negotiators, incident response teams and breach recovery consultants—is helping organizations evaluate recovery options after attacks.

According to Maus, decisions on whether to pay should consider multiple factors, including the type of data compromised, whether sensitive personal or healthcare information was exposed, and the identity of the threat group behind the attack.

Several cybersecurity experts argue that preventing attacks should take priority over debating ransom payments.

Gavin Millard, vice-president of product at Tenable, believes the primary focus should be on reducing ransomware profitability by strengthening organizations' security posture. He notes that many attacks continue to exploit known vulnerabilities, exposed systems and existing security gaps, making exposure management a critical defense strategy.

Walter also stresses the importance of maintaining strong cybersecurity practices, including continuous device monitoring and mandatory multi-factor authentication.

“What you really need is visibility over access to internal systems, and the ability to limit impact once they’re inside,” says Spencer Young, international senior vice-president at access management company Delinea. “Strong controls—like giving employees temporary, on-the-spot permission only when needed—shrink the blast radius and stop ransomware actors from achieving their goals.”

Meanwhile, Maus believes governments should focus on proactive cybersecurity investments instead of relying solely on payment bans.

Rather than prohibiting organizations from paying after an attack occurs, he argues that subsidizing secure backup infrastructure and offering tax incentives for cybersecurity investments “would do more to reduce the underlying exposure.”

US Sanctions on VPN Service Briefly Disrupt Telegram’s t.me Link Shortener Due to Compliance Action

 

iTelegram's t.me link-shortening domain briefly went offline earlier this week after a compliance action linked to US sanctions inadvertently affected the entire domain instead of a specific Telegram link.

Users began reporting on Monday that t.me short links were inaccessible after the domain was placed under a "serverHold" status, effectively making it unavailable across the internet. The registry status suggested that the action had been initiated by the domain's registry operator, causing widespread disruption to Telegram's link-sharing functionality.

Following the outage, Telegram CEO Pavel Durov reached out to DomainME, the registry responsible for managing the .me top-level domain, requesting an investigation into the issue.

On Tuesday, DomainME clarified the reason behind the disruption, stating, "t.me was on hold due to the OFAC compliance, but it is back online now."

The reference to OFAC points to the US Treasury Department's Office of Foreign Assets Control, which oversees and enforces US economic and trade sanctions. The same day the domain became unavailable, OFAC announced sanctions against First VPN Service, alleging that the platform had been used by multiple ransomware groups to conceal malicious activities targeting US businesses, hospitals, and government organizations.

As part of the sanctions, OFAC designated the VPN service's alleged administrator, Ukrainian national Dmytro Rashevskyi, along with associated infrastructure, including the domains 1vpns.com and 1vpns.net, as well as cryptocurrency wallet addresses. The sanctions are intended to prevent US individuals and businesses from engaging with the VPN provider.

According to reports, the sanctions documentation specifically referenced the Telegram support link t.me/FirstVPNService. This appears to have led to an unintended compliance action in which the entire t.me domain was placed on hold instead of only the sanctioned Telegram link.

In a subsequent statement, DomainME said, "the .ME Registry works closely with law enforcement to monitor and mitigate issues across the .ME domain in accordance with applicable laws, including sanctions requirements." The company suggested that the suspension was part of its sanctions compliance process rather than a simple technical error.

The t.me domain has since been restored and now redirects users to Telegram's primary website.

Meanwhile, the FBI has warned that First VPN Service, operational since 2014, has been widely used by cybercriminals. Investigators say at least 25 ransomware groups have relied on the VPN platform. While the service promoted itself as a privacy-focused VPN, authorities allege it has also been connected to botnet operations, distributed denial-of-service (DDoS) attacks, online scams, and hacking campaigns.

The FBI further stated, “First VPN Service was almost exclusively advertised in known criminal dark web forums such as Exploit[.]in and XSS[.]is, two of the most prominent Russian-language online forums which provide marketplaces for cyber criminals to buy and sell unauthorized access to computer systems, stolen personal identifying information, hacking tools, and contraband,” the agency added.

Unpatched Backdoor Identified in Firmware of Multiple Wi-Fi Routers


Research has discovered that several Tenda Wi-Fi routers are at risk of being compromised as a result of an undocumented authentication backdoor embedded in their firmware. An attacker can bypass the normal login process and gain administrator-level access to affected devices through this flaw, and no official security patch has been released yet. 

A US-based cybersecurity authority, CERT/CC (CERT/CC), identified the vulnerability and released it as a security advisory. According to the advisory, the backdoor is present in five firmware versions of older Tenda router models. A CVE-2026-11405 vulnerability has been assigned to this vulnerability. 

It is reported that the vulnerability is associated with the web server's login function, where a failed authentication attempt triggers a secondary verification process for passwords. Instead of validating both the username and password, firmware only checks the password value stored within the device configuration, which enables authentication to be successful regardless of the username used. 

In the case of Tenda devices, access is normally limited to administrator credentials via the web-based management interface. It has been discovered that the firmware contains an undocumented authentication mechanism that is activated upon failure of a standard login attempt. The firmware compares only a password stored in the device configuration, rather than validating both the username and password. Regardless of the username entered, administrative access is granted if the supplied password matches. 

Interestingly, researchers noted that the alternative password appears to be "rzadmin", which has previously been discovered in previous security research involving Tenda devices. However, since the authentication process does not validate the username, any username can successfully login when paired with the appropriate backdoor password. Despite the device's administrative interface, hidden functionality is not documented or disclosed. 

Upon matching the alternate password with the device configuration value, the firmware grants full administrator privileges and creates a valid management session. Because of its undocumented nature and inaccessibility through the standard administrative interface, it has been classified as an authentication backdoor by researchers. 

During previous security research involving Tenda devices, the alternate password was identified as "rzadmin", a credential that has previously surfaced. Despite the lack of clear explanations for its presence, experts believe it may have been accidentally left behind as part of a debugging or development tool. 

One of the biggest concerns is the lack of a vendor response. According to CERT/CC, they were unable to reach Tenda to coordinate a fix, resulting in the non-availability of official firmware updates for affected users. As a result, this vulnerability remains unpatched. Successful exploitation could result in router configuration changes, network settings changes, security settings being disabled, and potentially compromise other local networks. 

A security expert considers this vulnerability to be a significant risk for exposed devices due to its ability to grant administrator-level privileges without standard authentication. This firmware is affecting a variety of Tenda networking products, including routers, wireless hotspots, and other networking equipment. 
The following models have been confirmed as affected: 

  • FH1201 High Power AC1200 Dual-Band Wireless Router 
  • W15E v2.0 AC1200 Wireless Hotspot Router 
  • AC10 v1.0 AC1200 Smart Dual-Band Gigabit Router 
  • AC5 v1.0 AC1200 Smart Dual-Band Router 
  • AC6 v2.0 AC1200 Router 

There is a possibility that some of these products are older models and may already have reached end-of-life, resulting in uncertainty about future security updates. The CERT recommends that, until an official patch is available, remote web management be disabled and the router's default LAN IP address be changed to reduce exposure to automated internet scanning. 

If users have not received firmware updates for their affected devices and are unable to secure them, it may be prudent to replace the router with a supported model. Undocumented functionality embedded in networking firmware poses a number of security risks, particularly when vendors fail to provide timely security updates. 

Since there is no official patch available currently, users are advised to take immediate action to mitigate the vulnerability or to upgrade their hardware in order to reduce the risk of unauthorized access.

Microsoft-Signed Driver Used to Disable Security Software in GodDamn Ransomware Attacks

 


A ransomware group known as Hyadina has been observed using a Microsoft-signed Windows kernel driver to disable endpoint security software before deploying its latest ransomware variant, GodDamn, according to researchers at Symantec. The campaign combines trusted administrative software, publicly available offensive security tools and a signed kernel driver to establish control over victim environments before encrypting systems.

Hyadina has operated as a ransomware-as-a-service (RaaS) group for approximately four years, evolving its malware from earlier variants known as Beast and Monster to its current GodDamn locker. The group primarily targets organizations in the United States while reportedly avoiding victims in former Soviet countries. Previous attacks have affected organizations across healthcare, manufacturing, education and several other industries.

Symantec was unable to determine how the attackers initially gained access to the compromised environment. The first confirmed activity appeared on May 29, when an unauthorized copy of AnyDesk was discovered inside the Music folder of an infected system. Although AnyDesk is legitimate remote access software widely used for IT support, threat actors frequently abuse remote monitoring and management applications because they provide persistent access while blending into normal administrative activity.

The following day, the attackers deployed an executable named symantec.exe, which installed a kernel-mode driver called PoisonX. Running in the Windows kernel gives a driver the highest level of system privileges, allowing it to interact directly with core operating system functions. According to Symantec, PoisonX carried a valid Microsoft Hardware Compatibility signature, enabling Windows to load the driver as trusted.

Once active, PoisonX terminated security-related processes and removed user-mode API hooks commonly used by endpoint detection and response (EDR) solutions to monitor application behavior. By disabling those monitoring mechanisms, the attackers reduced the visibility of security software before carrying out the remaining stages of the intrusion.

With endpoint protections weakened, Hyadina expanded its operation using a collection of credential theft and reconnaissance utilities. Investigators observed fourteen open-source tools designed to recover credentials from web browsers, email clients and instant messaging applications, as well as utilities capable of extracting Wi-Fi credentials and capturing live network traffic. All but one of those tools originated from NirSoft, which publishes legitimate Windows administration utilities. The remaining tool, Mimikatz, is widely known for extracting credentials and authentication material from Windows systems and is frequently abused during post-compromise activity.

The attackers also relied on PsExec, Microsoft's remote administration utility, to move laterally across the victim's network. Combined with legitimate remote management software, credential theft utilities and the signed kernel driver, the attackers were able to strengthen their foothold across multiple systems before deploying the GodDamn ransomware payload.

Symantec also examined the origins of PoisonX. The driver was uploaded to GitHub on April 7 by a developer using the name oxfemale, who described it as a research tool. The developer regularly publishes offensive security projects, including exploit proof-of-concepts, credential stealers and software designed to disable antivirus products, while identifying themselves on LinkedIn as a Russian security researcher specializing in reverse engineering and penetration testing. Symantec, however, considers PoisonX to be malware because its primary function is to disable security protections rather than support legitimate defensive research. Researchers said it remains unclear how the driver obtained Microsoft's Hardware Compatibility signature or whether the signing process was manipulated.

Microsoft maintains a Vulnerable Driver Blocklist to prevent known malicious or exploitable drivers from loading, even when they possess valid signatures. However, Symantec noted that newly identified drivers are not added to the blocklist immediately. Updates can take days or, in some cases, weeks to reach enterprise systems, leaving a window during which attackers can continue using newly signed or newly discovered drivers before defensive protections are updated.

Commenting on the broader use of legitimate software during ransomware intrusions, Symantec's Brigid O Gorman noted that nearly any administrative or security tool can become malicious when misused. She said this makes behavioral and adaptive security controls particularly important because they focus on suspicious activity rather than relying solely on known malicious files or applications. In the case of Hyadina, that combination of trusted software, publicly available offensive tools and a signed kernel driver enabled the attackers to disable security protections, steal credentials, move laterally through the environment and ultimately deploy ransomware.

Why Digital Supply Chain Attacks Are Emerging as the Biggest Cybersecurity Threat for Businesses

 

As businesses strengthen their internal cybersecurity defenses, cybercriminals are increasingly shifting their focus to a more vulnerable target—the digital supply chain. Rather than attempting to breach organizations directly, attackers are exploiting trusted third-party vendors, software providers, cloud services, and open-source components that already have authorized access to critical systems and sensitive data.

Traditional cybersecurity strategies have long emphasized protecting internal networks through firewalls, encryption, access controls, and employee awareness programs. However, the growing reliance on interconnected digital ecosystems means these measures alone are no longer enough. Organizations now depend on a broad network of suppliers and technology partners, creating multiple entry points that hackers can exploit.

How Digital Supply Chain Attacks Work

Instead of targeting businesses head-on, cybercriminals increasingly infiltrate suppliers and service providers that support an organization's operations. These may include software vendors, web development companies, cloud storage providers, testing platforms, or third-party integrations.

A supply chain attack typically compromises one or more components that organizations rely on to deliver products or services. Attackers may introduce malicious software updates, steal login credentials, exploit insecure integrations, or take advantage of vulnerable open-source software libraries.

Open-source components present a particularly significant risk. Software developers often integrate publicly available libraries into applications to accelerate development. If attackers successfully insert malicious code into these widely used components, every organization that later incorporates them into their software may unknowingly introduce a serious security vulnerability.

One notable example occurred in 2024, when malicious code was embedded into XZ Utils, a widely used open-source compression utility for Linux systems. Rather than directly hacking organizations, attackers compromised the software supply chain itself. Although the affected versions had not yet reached widespread production deployment, they had already been integrated into development versions of major Linux distributions, forcing maintainers to rebuild packages after the vulnerability was identified.

Computer scientist Alex Stamos warned that if the attack had gone unnoticed, it would have “given its creators a master key to any of the hundreds of millions of computers around the world that run SSH”.

Once attackers successfully compromise a supplier's products or services, they can use that trusted access to infiltrate customer environments. In many cases, these attacks remain undetected until operations are disrupted, sensitive information is stolen or encrypted, or ransomware demands are issued. The XZ Utils compromise itself was only uncovered after a developer noticed unusual system performance during routine testing.

By the time organizations discover such incidents, significant operational and financial damage has often already occurred.

Cyberattacks frequently result in substantial financial losses. Organizations may face costly ransom demands, especially when attackers recognize that disruptions affect multiple customers or essential business services.

Even when no ransom is paid, businesses incur significant expenses related to operational downtime, system restoration, cybersecurity investigations, legal support, and business recovery.

For companies operating primarily through digital platforms, even short periods of downtime can severely impact revenue. Following a cyberattack in 2025, retailer Co-op reported that the incident “impacted both financial and operational areas”, leading to at least £206 million in lost revenue.

Operational disruptions can be equally damaging. If a critical supplier suspends services while containing a cyber incident, organizations may lose access to essential systems, preventing order fulfillment, transaction processing, and other core business functions.

A major example occurred in 2025 when Marks & Spencer (M&S) temporarily suspended online orders for nearly two months and relied on manual processing following a cyberattack. Rather than directly targeting M&S infrastructure, attackers exploited vulnerabilities in MoveIt, a widely used enterprise file transfer platform.

The breach exposed sensitive employee and customer information, including contact details, payroll records, and in certain cases, National Insurance numbers. Although payment information was reportedly unaffected, the scale of the incident triggered formal investigations, internal reviews, and regulatory scrutiny from the Information Commissioner's Office (ICO). The retailer estimated the financial impact at approximately £300 million in lost profits.

Beyond financial losses, reputational harm often proves to be the most enduring consequence of supply chain cyberattacks.

Customers generally do not distinguish between an organization and its suppliers when services fail. Regardless of where the breach originated, customers typically hold the business responsible.

Poor communication or delayed responses following an incident can rapidly erode trust that may have taken years to build. Restoring customer confidence often requires significant investment in communication, service improvements, and strengthened security measures, while long-term effects on customer loyalty and commercial relationships may continue long after systems have recovered.

Growing Regulatory Expectations

Regulators worldwide are increasingly emphasizing digital supply chain resilience as cyber risks extend beyond internal IT environments.

Under the UK's implementation of the General Data Protection Regulation (GDPR) through the Data Protection Act 2018, organizations acting as data controllers remain responsible for protecting personal information, even when third-party providers process that data on their behalf.

This means organizations must ensure their suppliers implement appropriate technical and organizational security measures while also reporting data breaches without unnecessary delay. Failure to meet these obligations can result in regulatory enforcement, financial penalties, and reputational damage.

The EU Artificial Intelligence Act follows a similar principle for AI technologies. Organizations deploying AI systems—including those supplied by external vendors—are expected to understand how those systems function, the associated cybersecurity risks, and how they are secured, particularly when high-risk AI applications are involved.

As a result, regulators increasingly expect businesses to actively manage cyber and AI risks throughout their digital supply chains rather than relying solely on vendor assurances.

Organizations are therefore encouraged to establish comprehensive cybersecurity governance frameworks that include supplier due diligence, continuous monitoring, documented risk management processes, and clearly defined incident response procedures.

Best Practices to Reduce Supply Chain Cyber Risks

While eliminating supply chain risk entirely is impossible, organizations can significantly reduce exposure by adopting proactive security measures, including:

  • Performing comprehensive cybersecurity due diligence before engaging suppliers.
  • Verifying vendors maintain strong security controls such as patch management, employee training, access management, and multi-factor authentication.
  • Conducting regular risk assessments across the supply chain to identify critical vulnerabilities.
  • Including clear cybersecurity obligations, incident reporting requirements, liability provisions, audit rights, and data protection clauses within supplier contracts.
  • Thoroughly testing systems and software developed by external vendors before deployment.
  • Providing guidance and collaboration to strengthen cybersecurity across supplier networks.
  • Developing and regularly updating incident response plans that specifically address third-party cyber incidents, customer communications, regulatory reporting, and ransomware scenarios.
  • Promoting cybersecurity awareness through continuous education and information sharing among internal teams and external partners.
  • Investing in cyber insurance while ensuring key suppliers also maintain appropriate coverage.
As organizations become increasingly dependent on interconnected technologies, digital platforms, and external suppliers, cybersecurity has evolved into a broader governance challenge rather than simply an IT responsibility.

Recent cyber incidents demonstrate how weaknesses within trusted supplier networks can rapidly escalate into severe financial losses, operational disruptions, and long-term reputational damage.

Regulators now expect organizations to proactively identify, assess, and manage supply chain cyber risks before incidents occur. Businesses that invest in stronger supplier oversight, robust governance, and comprehensive risk management strategies will be better positioned to safeguard operations, meet regulatory obligations, and preserve customer trust in an increasingly connected digital landscape.

BeyondTrust Patches Four Vulnerabilities in Remote Support and PRA

 




BeyondTrust has released security updates to remediate four vulnerabilities affecting its Remote Support (RS) and Privileged Remote Access (PRA) solutions, including two Critical authentication bypass flaws that could allow attackers to gain unauthorized access to vulnerable appliances under specific deployment configurations. The products are commonly used by organizations to deliver remote technical support and manage privileged access to enterprise systems, making them attractive targets because they often provide administrative access to critical IT environments.

The most severe issues originate within the products' authentication mechanisms, which verify user identities before granting access. Because the vulnerabilities can be triggered before the authentication process is completed, successful exploitation may allow attackers to bypass an important security control without first supplying valid credentials.

One of the Critical vulnerabilities, tracked as CVE-2026-40138, carries a CVSS score of 9.2 and affects both BeyondTrust Remote Support and Privileged Remote Access. According to the advisory, the flaw stems from improper validation of authentication data within the authentication subsystem. Under specific authentication configurations, a network-positioned attacker could bypass access controls and obtain unauthorized access to the appliance, including accounts with elevated privileges.

BeyondTrust also addressed CVE-2026-40139, another Critical vulnerability assigned a CVSS score of 9.2 that impacts Remote Support. The issue results from improper processing of authentication requests and could enable an unauthenticated remote attacker to circumvent authentication controls and gain unauthorized access to affected appliances, including privileged accounts. Similar to CVE-2026-40138, exploitation depends on a particular authentication configuration being enabled, meaning the exposure varies according to how affected environments are deployed.

In addition to the authentication bypass flaws, the company disclosed CVE-2026-40140, a High-severity vulnerability with a CVSS score of 8.7 affecting the network communication subsystem. The issue arises from insufficient validation of client-supplied input and could allow an unauthenticated remote attacker to trigger a denial-of-service (DoS) condition, disrupting the availability of vulnerable appliances rather than providing direct access to them.

The fourth vulnerability, CVE-2026-40141, received a CVSS score of 8.5 and affects web application components within both Remote Support and Privileged Remote Access. Caused by inadequate validation of user-supplied input, the flaw could enable an authenticated user with limited privileges to access resources or information beyond their intended authorization. BeyondTrust noted that exploitation of this vulnerability is limited to accounts that already possess specific permissions.

The company said the vulnerabilities were identified during ongoing internal security assessments with assistance from publicly available artificial intelligence models, including Anthropic Claude Opus 4.8, alongside BeyondTrust's proprietary security research tooling. The use of AI-supported analysis reflects a growing trend of incorporating large language models into vulnerability research to assist security teams in identifying potential weaknesses alongside conventional testing techniques.

According to BeyondTrust, the most severe vulnerabilities could allow authentication bypass and unauthorized access when affected systems are configured in specific ways. The remaining flaws could result in service disruption, unintended access to data, or expanded privileges for authenticated users under defined conditions, potentially affecting the confidentiality, availability, and integrity of vulnerable systems.

The vulnerabilities have been resolved in Remote Support version 25.3.3 and later and Privileged Remote Access version 25.3.3 and later. Organizations running version 25.3.2 or earlier of either product are advised to upgrade to the latest available release to mitigate the disclosed risks.

BeyondTrust stated that it has not observed evidence of the newly disclosed vulnerabilities being exploited in the wild. Nevertheless, the company noted that its Remote Support and Privileged Remote Access products have previously been targeted by threat actors. Earlier vulnerabilities, including CVE-2024-12356 and CVE-2026-1731, were exploited to deploy web shells and backdoors on compromised appliances, demonstrating the continued interest of attackers in enterprise remote access infrastructure. Given that history and the privileged role these products play within enterprise environments, organizations are encouraged to apply the available security updates promptly to reduce their exposure to potential attacks.
