Symantec Links Betruger Backdoor Malware to RansomHub Ransomware Attacks

 

A sophisticated custom backdoor malware called Betruger has been discovered in recent ransomware campaigns, with Symantec researchers linking its use to affiliates of the RansomHub ransomware-as-a-service (RaaS) group. The new malware is considered a rare and powerful tool designed to streamline ransomware deployment by minimizing the use of multiple hacking tools during attacks. 

Identified by Symantec’s Threat Hunter Team, Betruger is described as a “multi-function backdoor” built specifically to aid ransomware operations. Its functions go far beyond traditional malware. It is capable of keylogging, network scanning, privilege escalation, credential theft, taking screenshots, and uploading data to a command-and-control (C2) server—all typical actions carried out before a ransomware payload is executed. Symantec notes that while ransomware actors often rely on open-source or legitimate software like Mimikatz or Cobalt Strike to navigate compromised systems, Betruger marks a departure from this norm. 

The tool’s development suggests an effort to reduce detection risks by limiting the number of separate malicious components introduced during an attack. “The use of custom malware other than encrypting payloads is relatively unusual in ransomware attacks,” Symantec stated. “Betruger may have been developed to reduce the number of tools dropped on a network during the pre-encryption phase.” Threat actors are disguising the malware under file names like ‘mailer.exe’ and ‘turbomailer.exe’ to pose as legitimate mailing applications and evade suspicion. While custom malware isn’t new in ransomware operations, most existing tools focus on data exfiltration. 

Notable examples include BlackMatter’s Exmatter and BlackByte’s Exbyte, both created to steal data and upload it to cloud platforms like Mega.co.nz. However, Betruger represents a more all-in-one solution tailored for streamlined attack execution. The RansomHub RaaS operation, previously known as Cyclops and Knight, surfaced in early 2024 and has quickly become a major threat actor in the cybercrime world. Unlike traditional ransomware gangs, RansomHub has focused more on data theft and extortion rather than just data encryption. Since its emergence, RansomHub has claimed several high-profile victims including Halliburton, Christie’s auction house, Frontier Communications, Rite Aid, Kawasaki’s EU division, Planned Parenthood, and Bologna Football Club. 

The group also leaked Change Healthcare’s stolen data after the BlackCat/ALPHV ransomware group’s infamous $22 million exit scam. More recently, the gang claimed responsibility for breaching BayMark Health Services, North America’s largest addiction treatment provider. BayMark serves over 75,000 patients daily across more than 400 locations in the US and Canada. According to the FBI, as of August 2024, RansomHub affiliates have compromised over 200 organizations, many of which are part of critical infrastructure sectors such as government, healthcare, and energy. 

As ransomware groups evolve and adopt more custom-built malware like Betruger, cybersecurity experts warn that defenses must adapt to meet increasingly sophisticated threats.

Fourlis Group Confirms €20 Million Loss from IKEA Ransomware Attack

 

Fourlis Group, the retail operator responsible for IKEA stores across Greece, Cyprus, Romania, and Bulgaria, has revealed that a ransomware attack targeting its systems in late November 2024 led to significant financial losses. The cyber incident, which coincided with the busy Black Friday shopping period, disrupted critical parts of the business and caused damages estimated at €20 million (around $22.8 million). 

The breach initially surfaced as unexplained technical problems affecting IKEA’s e-commerce platforms. Days later, on December 3, the company confirmed that the disruptions were due to an external cyberattack. The attack affected digital infrastructure used for inventory restocking, online transactions, and broader retail operations, mainly impacting IKEA’s business. Other brands under the Fourlis umbrella, including Intersport and Holland & Barrett, were largely unaffected.  

According to CEO Dimitris Valachis, the company experienced a loss of approximately €15 million in revenue by the end of 2024, with an additional €5 million impact spilling into early 2025. Fourlis decided not to comply with the attackers’ demands and instead focused on system recovery through support from external cybersecurity professionals. The company also reported that it successfully blocked a number of follow-up attacks attempted after the initial breach. 

Despite the scale of the attack, an internal investigation supported by forensic analysts found no evidence that customer data had been stolen or exposed. The incident caused only a brief period of data unavailability, which was resolved swiftly. As part of its compliance obligations, Fourlis reported the breach to data protection authorities in all four affected countries, reassuring stakeholders that personal information remained secure. Interestingly, no known ransomware group has taken responsibility for the attack. This may suggest that the attackers were unable to extract valuable data or are holding out hope for an undisclosed settlement—though Fourlis maintains that no ransom was paid. 

The incident highlights the growing risks faced by digital retail ecosystems, especially during peak sales periods when system uptime is critical. As online platforms become more central to retail operations, businesses like Fourlis must invest heavily in cybersecurity defenses. Their experience reinforces the importance of swift response strategies, external threat mitigation support, and robust data protection practices to safeguard operations and maintain customer trust in the face of evolving cyber threats.

Ransomware Attacks Surge in Q1 2025 as Immutable Backup Emerges as Critical Defense

Ransomware attacks have seen a dramatic rise in the first quarter of 2025, with new research from Object First revealing an 84% increase compared to the same period in 2024. This alarming trend highlights the growing sophistication and frequency of ransomware campaigns, with nearly two-thirds of organizations reporting at least one attack in the past two years. 

The findings suggest that ransomware is no longer a matter of “if” but “when” for most businesses. Despite the increased threat, Object First’s study offers a silver lining. A large majority—81% of IT decision-makers—now recognize that immutable backup storage is the most effective defense against ransomware. Immutable storage ensures that once data is written, it cannot be changed or deleted, offering a critical safety net when other security measures fail. This form of storage plays a key role in enabling organizations to recover their data without yielding to ransom demands. 

However, the report also highlights a concerning gap between awareness and action. While most IT professionals acknowledge the benefits of immutable backups, only 59% of organizations have actually implemented such storage. Additionally, just 58% maintain multiple copies of their data in separate locations, falling short of the recommended 3-2-1 backup strategy. This gap leaves many companies dangerously exposed. The report also shows that ransomware actors are evolving their methods. A staggering 96% of organizations that experienced ransomware attacks in the last two years had their backup systems targeted at least once. Even more concerning, 10% of them had their backup storage compromised in every incident. 

These findings demonstrate how attackers now routinely seek to destroy recovery options, increasing pressure on victims to pay ransoms. Many businesses still place heavy reliance on traditional IT security hardening. In fact, 61% of respondents believe this approach is sufficient. But ransomware attackers are adept at bypassing such defenses using phishing emails, stolen credentials, and remote access tools. That’s why Object First recommends adopting a “breach mentality”—an approach that assumes an eventual breach and focuses on limiting damage. 

A Zero Trust architecture, paired with immutable backup, is essential. Organizations are urged to segment networks, restrict user access to essential data only, and implement multi-factor authentication. As cloud services grow, many companies are also turning to immutable cloud storage for flexible, scalable protection. Together, these steps offer a stronger, more resilient defense against today’s aggressive ransomware landscape.

CVE CVEs Cyber Attacks Malware Attack Malwares Microsoft ransomware attacks Ransomware group Ransomwares

Windows CLFS Zero-Day CVE-2025-29824 Exploited by Ransomware Group Storm-2460

 

A newly disclosed Windows zero-day vulnerability, tracked as CVE-2025-29824, is being actively exploited in cyberattacks to deliver ransomware, Microsoft has warned. This flaw affects the Windows Common Log File System (CLFS) driver and enables local privilege escalation—a method often used by attackers after gaining initial access. 

Microsoft’s Threat Intelligence and Security Response teams revealed that the bug is classified as a “use-after-free” vulnerability with a severity score of 7.8. While attackers need to compromise a system before they can exploit this flaw, it remains highly valuable in ransomware operations. Cybercriminals often rely on these types of vulnerabilities to turn a limited foothold into full administrative control across networks. 

The cybercrime group currently leveraging this zero-day is known as Storm-2460. Microsoft reports that the group is using the exploit to deploy a custom backdoor named PipeMagic, which in turn facilitates the installation of RansomEXX ransomware—a variant not commonly observed but still capable of serious disruption. So far, Storm-2460 has targeted organizations in industries such as IT, finance, and retail, with victims located in countries including the United States, Spain, Saudi Arabia, and Venezuela. 

Microsoft emphasized that the number of known cases remains small, but the sophistication of the exploit is concerning. This attack is notable for being part of a “post-compromise” campaign, meaning the attacker already has a presence within the system before using the flaw. These types of exploits are frequently used to escalate privileges and move laterally within a network, eventually leading to broader ransomware deployment. Microsoft issued a security advisory for CVE-2025-29824 on April 8 and urged organizations to install updates immediately. Failure to do so could leave critical systems vulnerable to privilege escalation and full network compromise. 

To mitigate risk, Microsoft advises businesses to prioritize patch management, restrict unnecessary administrative privileges, and closely monitor for unusual behavior across endpoints. Cybersecurity teams are also encouraged to review logs for any indicators of compromise related to PipeMagic or RansomEXX. As ransomware tactics continue to evolve, the exploitation of vulnerabilities like CVE-2025-29824 reinforces the need for proactive defense strategies and rapid incident response protocols.

Cyber Security Extension Malware Detection Malwares Marketplace Microsoft Microsoft security Ransomwares Security Flaws

Ransomware Found in VSCode Extensions Raises Concerns Over Microsoft’s Security Review

 

Cybersecurity experts have discovered ransomware hidden within two Visual Studio Code (VSCode) Marketplace extensions, raising concerns about Microsoft’s ability to detect malicious software in its platform. The compromised extensions, named “ahban.shiba” and “ahban.cychelloworld,” were downloaded by users before security researchers flagged them and they were subsequently removed. 

Despite Microsoft’s security measures, the extensions remained publicly accessible for a significant period, highlighting potential gaps in the company’s review process. The “ahban.cychelloworld” extension was first uploaded on October 27, 2024, followed by “ahban.shiba” on February 17, 2025. The VSCode Marketplace, designed to provide developers with additional tools for Microsoft’s popular coding platform, has come under scrutiny for failing to identify these threats. 

Researchers at ReversingLabs determined that both extensions included a PowerShell script that connected to a remote Amazon Web Services (AWS) server to download further malicious code. This secondary payload functioned as ransomware, though evidence suggests it was still in a testing phase. 

Unlike traditional ransomware that encrypts entire systems, this malware specifically targeted files stored in C:\users%username%\Desktop\testShiba.  Once the encryption was complete, victims received a Windows notification stating: “Your files have been encrypted. Pay 1 ShibaCoin to ShibaWallet to recover them.” However, no further instructions or payment details were provided, suggesting the malware was not yet fully developed.  

Although Microsoft eventually removed the extensions, security researcher Italy Kruk from ExtensionTotal disclosed that their automated detection system had identified the malicious code much earlier. Kruk stated that they had alerted Microsoft about the issue but received no response. Further analysis revealed that the initial version of “ahban.cychelloworld” was clean, but the ransomware was introduced in version 0.0.2, which was released on November 24, 2024. ExtensionTotal flagged this version to Microsoft on November 25, yet the extension remained available for months. 

During this time, five more versions were uploaded, all containing the same ransomware. This case has intensified concerns about Microsoft’s ability to monitor third-party extensions effectively. The security lapse within the VSCode Marketplace highlights the risk developers face when downloading extensions, even from official sources. Microsoft has previously faced criticism for both slow responses to security threats and for mistakenly removing non-malicious extensions. 

A notable example involved two popular VSCode themes, ‘Material Theme – Free’ and ‘Material Theme Icons – Free,’ which were taken down due to suspected obfuscated JavaScript. However, after further review, Microsoft determined the extensions were safe, reinstated them, and apologized, promising improvements to its security screening process. The presence of ransomware in widely used developer tools underscores the need for stronger security measures. Developers must stay cautious, regularly update security protocols, and carefully evaluate third-party extensions before installing them, even when they come from official platforms like the VSCode Marketplace.

Betruger Backdoor Linked to RansomHub Ransomware Attacks on Critical Infrastructure

 

A newly discovered backdoor malware, dubbed Betruger, has been identified in multiple recent ransomware attacks. Researchers at Symantec believe at least one affiliate of the RansomHub ransomware-as-a-service (RaaS) operation is using this sophisticated tool to facilitate cyber intrusions. 

Unlike many conventional malware strains, Betruger functions as a multi-purpose backdoor designed to prepare networks for ransomware deployment while minimizing the need for additional malicious software. Betruger comes equipped with several advanced features commonly associated with pre-ransomware attack stages. These include keylogging, network scanning, privilege escalation, credential theft, screenshot capture, and the ability to upload files to a command-and-control (C2) server. 

Its design suggests that attackers are looking to streamline their intrusion process, reducing reliance on multiple external tools and instead using a single, custom-built malware to execute various attack functions. This approach is relatively rare, as ransomware operators typically rely on widely available tools such as Mimikatz and Cobalt Strike to conduct their attacks. To avoid detection, cybercriminals are disguising Betruger under the filenames ‘mailer.exe’ and ‘turbomailer.exe,’ making it appear like a legitimate email-related application. 

While other ransomware groups have developed proprietary tools for data exfiltration, such as BlackMatter’s Exmatter and BlackByte’s Exbyte, Betruger appears to have a broader range of capabilities beyond just stealing data. The emergence of Betruger coincides with ongoing attacks by RansomHub, a ransomware operation that has been active since February 2024. Previously known as Cyclops and Knight, RansomHub has gained a reputation for focusing on extortion through data theft rather than encrypting victim files. 

Over the past year, the group has targeted several major organizations, including Halliburton, Christie’s, Frontier Communications, Rite Aid, and Kawasaki’s EU division. It was also responsible for leaking Change Healthcare’s stolen data after the BlackCat/ALPHV group’s $22 million exit scam. More recently, RansomHub claimed responsibility for breaching BayMark Health Services, a leading addiction treatment provider in North America. 

The company operates over 400 treatment centers across the U.S. and Canada, serving approximately 75,000 patients daily. The FBI has linked RansomHub affiliates to more than 200 ransomware attacks affecting various critical infrastructure sectors in the U.S., including government agencies, healthcare institutions, and other essential services. With the deployment of Betruger, the group’s operations appear to be evolving, indicating a continued threat to businesses and organizations worldwide.

Hackers Exploit Fortinet Firewall Bugs to Deploy Ransomware

 

Cybersecurity researchers have uncovered a new attack campaign in which hackers are exploiting vulnerabilities in Fortinet firewalls to breach corporate networks and deploy ransomware. The hacking group, tracked as “Mora_001,” is leveraging two specific flaws in Fortinet’s firewall software to infiltrate systems and launch a custom ransomware strain called “SuperBlack.” 

These vulnerabilities, tracked as CVE-2024-55591 and CVE-2025-24472, have been actively exploited since December 2024, despite Fortinet releasing patches in January 2025. Many organizations have yet to apply these critical updates, leaving their networks vulnerable. Once inside a network, the attackers conduct reconnaissance to identify valuable data before deploying ransomware. Instead of immediately encrypting files, they first exfiltrate sensitive information, a tactic that has become increasingly common among ransomware groups seeking to pressure victims into paying a ransom to prevent data leaks. 

Security researchers at Forescout observed that the Mora_001 group selectively encrypted file servers only after stealing critical data, making their attacks more damaging and difficult to recover from. There is strong evidence linking Mora_001 to the notorious LockBit ransomware gang. The SuperBlack ransomware strain appears to be based on a leaked builder from LockBit 3.0 attacks, and the ransom notes left by Mora_001 include the same contact details previously used by LockBit affiliates. This suggests that Mora_001 may be a current LockBit affiliate with distinct operational methods or a separate group that shares infrastructure and communication channels. 

Cybersecurity experts believe that Mora_001 is primarily targeting organizations that have not yet applied Fortinet’s security patches. Companies that failed to update their firewalls or properly harden their network configurations when the vulnerabilities were first disclosed are at the highest risk. The ransom notes used in these attacks also bear similarities to those used by other cybercriminal groups, such as the now-defunct ALPHV/BlackCat ransomware gang, further indicating connections within the ransomware ecosystem. 

Despite Fortinet releasing fixes for the affected vulnerabilities, unpatched systems remain an easy target for attackers. Security professionals are urging organizations to update their firewalls immediately and implement additional security measures to prevent unauthorized access. Best practices include applying all available patches, segmenting networks to restrict access to critical systems, monitoring for suspicious activity using endpoint detection and response tools, and maintaining secure offline backups. Organizations that fail to take these precautions risk falling victim to sophisticated ransomware attacks that can result in severe financial and operational damage.

Akira Akira Ransomware Camera Hack Cyber Attacks EDR Ransomware attack Ransomwares RDP S-RM

Ransomware Group Uses Unpatched Webcams to Deploy Attacks

 

A recent cybersecurity report by S-RM has revealed a new tactic used by the Akira ransomware group, demonstrating their persistence in bypassing security defenses. When their initial attempt to deploy ransomware was blocked by an endpoint detection and response (EDR) tool, the attackers shifted their focus to an unexpected network device—a webcam. 

This strategy highlights the evolving nature of cyber threats and the need for organizations to secure all connected devices. The attack began with the use of remote desktop protocol (RDP) to access a target’s server. When the group attempted to deploy a ransomware file, the victim’s EDR successfully detected and neutralized the threat. However, rather than abandoning the attack, the adversaries conducted a network search and identified other connected devices, including a fingerprint scanner and a camera. The camera was an ideal entry point because it was unpatched, ran a Linux-based operating system capable of executing commands, and had no installed EDR solution. 

Exploiting these vulnerabilities, the attackers used the camera to deploy ransomware via the Server Message Block (SMB) protocol, which facilitates file and resource sharing between networked devices. According to cybersecurity experts, this kind of attack is difficult to defend against because it targets overlooked devices. Rob T. Lee, chief of research at the SANS Institute, compared detecting such threats to “finding a needle in a haystack.” The attack underscores how cybercriminals are constantly adapting, looking for the weakest points in a network to infiltrate and execute their malicious operations. 

The Akira ransomware group has gained traction following law enforcement takedowns of major ransomware organizations like AlphV and LockBit. S-RM reported that Akira accounted for 15% of the cyber incidents it analyzed, and in January 2024, CISA confirmed that the group had impacted over 250 organizations, extorting approximately $42 million in ransom payments. Ransom demands from Akira typically range from $200,000 to $4 million. The growing threat to internet of things (IoT) devices is further supported by data from Zscaler, which blocked 45% more IoT malware transactions between June 2023 and May 2024. 

Devices such as webcams, e-readers, and routers are particularly vulnerable due to outdated software and poor security practices. To mitigate risks, cybersecurity experts recommend several best practices for securing IoT devices. Organizations should place IoT devices on restricted networks that prevent unauthorized access from workstations or servers. Unused devices should be turned off, networked devices should be regularly audited, and software patches must be applied promptly. Additionally, changing default passwords on IoT devices is essential to prevent unauthorized access. 

Cybercriminals are continuously thinking outside the box to exploit vulnerabilities, and security professionals must do the same to defend against emerging threats. If attackers can compromise a webcam, they could potentially target more complex systems, such as industrial machinery or medical devices. As ransomware groups evolve, staying ahead of their tactics is crucial for safeguarding sensitive data and preventing costly breaches.

CISA & FBI CISA advisory Cyber Attacks Malwares Medusa Attacks Medusa Ransomware RaaS ransomware attacks ransomware-as-a-service (RaaS) Ransomwares

Medusa Ransomware Attacks: CISA, FBI, and MS-ISAC Issue #StopRansomware Advisory

 

The Cybersecurity and Infrastructure Security Agency (CISA), in partnership with the FBI and the Multi-State Information Sharing and Analysis Center (MS-ISAC), has issued a #StopRansomware advisory, warning organizations about the increasing threat of Medusa ransomware. 

Medusa, a ransomware-as-a-service (RaaS) variant, was first detected in 2021 and has since targeted over 300 victims across multiple critical infrastructure sectors. Industries such as healthcare, law, education, insurance, technology, and manufacturing have been particularly affected, highlighting the wide reach and severity of the ransomware’s impact. Medusa initially operated as a closed ransomware variant, meaning its developers had full control over its deployment and operations. 

Over time, it transitioned to an affiliate-based model, allowing external cybercriminals to use the ransomware while keeping certain aspects, such as ransom negotiations, under the control of the original developers. This shift has allowed Medusa to expand its reach, increasing its effectiveness as a cyber threat. Medusa demands ransoms ranging from $100,000 to as much as $15 million. 

Like many modern ransomware variants, it employs double extortion tactics—stealing sensitive data before encrypting victim networks. This strategy puts additional pressure on victims, as attackers can threaten to leak or sell stolen data if the ransom is not paid. Cybersecurity researchers from Symantec’s Threat Hunter team recently reported a rise in Medusa-related attacks over the past year. 

Medusa’s developers use initial access brokers (IABs) to gain entry into victim networks. These brokers operate within cybercriminal forums and marketplaces, selling access to compromised systems for amounts ranging from $100 to $1 million. Medusa affiliates rely on phishing campaigns and vulnerability exploitation to gain initial access, making it crucial for organizations to bolster their email security and patch known vulnerabilities. Once inside a system, Medusa operators use “living-off-the-land” (LotL) techniques, leveraging legitimate system tools to evade detection while conducting reconnaissance, data theft, and lateral movement.

Given Medusa’s evolving tactics, cybersecurity experts stress the importance of proactive defense measures. Organizations should deploy security patches, implement network segmentation, and restrict access to critical services from untrusted sources. Dan Lattimer, area vice president for Semperis in the UK and Ireland, emphasized the need for an “assumed breach” mindset, urging companies to shift from a prevention-focused approach to rapid detection, response, and recovery. 

As ransomware attacks grow more sophisticated, organizations must remain vigilant, continuously updating their cybersecurity strategies to mitigate risks and strengthen their defenses against threats like Medusa.

Tata Technologies Cyberattack: Hunters International Ransomware Gang Claims Responsibility for 1.4TB Data Theft

 

Hunters International, a ransomware group known for high-profile cyberattacks, has claimed responsibility for a January 2025 cyberattack on Tata Technologies. The group alleges it stole 1.4TB of sensitive data from the company and has issued a threat to release the stolen files if its ransom demands are not met. Tata Technologies, a Pune-based global provider of engineering and digital solutions, reported the cyberattack in January. 

The company, which operates in 27 countries with over 12,500 employees, offers services across the automotive, aerospace, and industrial sectors. At the time of the breach, Tata Technologies confirmed that the attack had caused disruptions to certain IT systems but stated that client delivery services remained unaffected. The company also assured stakeholders that it was actively restoring impacted systems and conducting an internal investigation with cybersecurity experts. 

However, more than a month later, Hunters International listed Tata Technologies on its dark web extortion page, taking responsibility for the attack. The group claims to have exfiltrated 730,000 files, totaling 1.4TB of data. While the ransomware gang has threatened to publish the stolen files within a week if a ransom is not paid, it has not provided any samples or disclosed the nature of the compromised documents. Tata Technologies has yet to release an update regarding the breach or respond to the hackers’ claims. 

BleepingComputer, a cybersecurity news platform, attempted to contact the company for a statement but did not receive an immediate response. Hunters International emerged in late 2023, suspected to be a rebranded version of the Hive ransomware group. Since then, it has carried out multiple high-profile attacks, including breaches of Austal USA, a U.S. Navy contractor, and Japanese optics company Hoya. 

The group has gained notoriety for targeting various organizations without ethical restraint, even engaging in extortion schemes against individuals, such as cancer patients from Fred Hutchinson Cancer Center. Although many of the gang’s claims have been verified, some remain disputed. For example, in August 2024, the U.S. Marshals Service denied that its systems had been compromised, despite Hunters International’s assertions.  

With cybercriminals continuing to exploit vulnerabilities, the Tata Technologies breach serves as another reminder of the persistent and evolving threats posed by ransomware groups.

Cyberattacks on Single Points of Failure Are Driving Major Industry Disruptions


Cybercriminals are increasingly targeting single points of failure within companies, causing widespread disruptions across industries. According to cybersecurity firm Resilience, attackers have shifted their focus toward exploiting key vulnerabilities in highly interconnected organizations, triggering a “cascading effect of disruption and chaos downstream.” This strategy allows cybercriminals to maximize the impact of their attacks, affecting not just the initial target but also its partners, clients, and entire industries. 


The financial consequences of these attacks have been severe. According to IBM research, the global average cost of a data breach in 2024 was nearly $4.9 million. However, some breaches were far more expensive. One of the most significant incidents involved a ransomware attack on Change Healthcare, a subsidiary of UnitedHealth that processes billions of medical claims annually. UnitedHealth reported that the attack cost the company $3.1 billion in response efforts, making it one of the most financially damaging cyber incidents in recent history. 

The attack caused major disruptions across the healthcare sector, impacting hospitals, insurance providers, and pharmacies. John Riggi, national cybersecurity advisor for the American Hospital Association, described the incident as “the most significant and consequential cyberattack in the history of U.S. health care.” Another major ransomware attack targeted CDK Global, a software provider for car dealerships across the U.S. The breach resulted in over $1 billion in collective losses for affected dealerships, according to estimates from Anderson Economic Group. 

This attack further demonstrated how cybercriminals can cripple entire industries by targeting critical service providers that businesses rely on for daily operations. Resilience’s analysis indicates that third-party risk has become a dominant driver of cyber insurance claims. In 2024, third-party breaches accounted for 31% of all claims filed by its clients. While the number was slightly higher in 2023 at 37%, none of those incidents resulted in material financial losses. The report also found that ransomware targeting vendors has become a significant concern, contributing to 18% of all incurred claims.  

Ransomware remained the top cause of financial loss in cyber incidents last year, responsible for 62% of claims involving monetary damages. However, Resilience’s research suggests that while ransomware remains a major threat, its frequency may be declining in broader markets. This trend is attributed to cybercriminals shifting their focus from random, large-scale attacks to more strategic operations against high-value targets that offer larger payouts. 

The evolving threat landscape underscores the need for organizations to strengthen cybersecurity measures, particularly in highly interconnected industries. With cyberattacks becoming more sophisticated and financially motivated, businesses must prioritize risk management, enhance third-party security assessments, and invest in cyber resilience to prevent large-scale disruptions.

Lee Enterprises Faces Prolonged Ransomware Attack Disrupting Newspaper Operations

 

Lee Enterprises, one of the largest newspaper publishers in the United States, is facing an ongoing ransomware attack that has severely disrupted its operations for over three weeks. The company confirmed the attack in a filing with the U.S. Securities and Exchange Commission (SEC), revealing that hackers illegally accessed its network, encrypted critical applications, and exfiltrated certain files. 

The publishing giant is now conducting a forensic investigation to determine whether sensitive or personal data was stolen. The attack has had widespread consequences across Lee’s business, affecting essential operations such as billing, collections, vendor payments, and the distribution of print newspapers. Many of its 72 publications have experienced significant delays, with some print editions not being published at all. 

The Winston-Salem Journal in North Carolina reported that it was unable to print several editions, while the Albany Democrat-Herald and Corvallis Gazette-Times in Oregon faced similar disruptions, preventing the release of at least two editions. Digital services have also been affected. On February 3, Lee Enterprises notified affected media outlets that one of its data centers, which supports applications and services for both the company and its customers, had gone offline. 

This outage has prevented subscribers from logging into their accounts and accessing key business applications. Several Lee-owned newspaper websites now display maintenance messages, warning readers that subscription services and digital editions may be temporarily unavailable. The full impact of the attack is still being assessed, but Lee has acknowledged that the incident is “reasonably likely” to have a material financial impact. With print and digital disruptions continuing, the company faces potential revenue losses from advertising, subscription cancellations, and operational delays. 

Law enforcement has been notified, though the company has not disclosed details about the perpetrators or whether it is considering paying a ransom. Ransomware attacks typically involve cybercriminals encrypting a company’s data and demanding payment in exchange for its release. If Lee refuses to negotiate, it may take weeks or months to fully restore its systems. 

Cyberattacks targeting media organizations have become increasingly common, as newspapers and digital publications rely on complex networks that can be vulnerable to security breaches. The Freedom of the Press Foundation is currently tracking the scope of the attack and compiling a list of affected newspapers. For now, Lee Enterprises continues its recovery efforts while its newspapers work to restore regular operations. 

Until the attack is fully resolved, readers, advertisers, and employees may continue to face disruptions across print and digital platforms. The incident highlights the growing threat of ransomware attacks on critical infrastructure and the challenges companies face in securing their networks against cyber threats.

Ransomware Tactics Evolve as Hackers Shift Focus to Data Theft

 

Ransomware groups are adapting their strategies to outsmart stronger cybersecurity defenses and increasing law enforcement pressure, according to the Huntress 2025 Cyber Threat Report. The findings reveal that attackers are moving beyond traditional encryption-based ransomware, instead focusing on data theft and extortion to bypass modern protections. 

In 2024, 75% of ransomware cases Huntress investigated involved remote access Trojans (RATs), allowing hackers to infiltrate systems discreetly. Additionally, 17.3% of incidents featured the misuse of legitimate remote management tools such as ConnectWise ScreenConnect, TeamViewer, and LogMeIn. This shift reflects a growing reliance on “living off the land” techniques, where attackers use trusted administrative tools to avoid detection. 

A significant trend noted in the report is that sophisticated tactics once reserved for targeting large enterprises are now common across businesses of all sizes. Huntress observed that cybercriminals are increasingly disabling or tampering with security software to maintain access and avoid detection, effectively closing the gap between attacks on major corporations and smaller organizations.  

Huntress’ analysis of over 3 million endpoints also revealed that nearly 24% of ransomware incidents in 2024 involved infostealer malware, while malicious scripts designed to automate attacks and evade security tools appeared in 22% of cases. Greg Linares, principal threat intelligence analyst at Huntress, states that ransomware groups must constantly evolve to survive in the competitive cybercrime landscape.

“If malware isn’t staying ahead of detection techniques, it becomes obsolete fast,” Linares explained. Another key insight from the report was the speed of modern ransomware campaigns. On average, the time from initial access to the delivery of a ransom demand — known as time-to-ransom (TTR) — was just 17 hours. Some groups, including Play, Akira, and Dharma/Crysis, were even faster, with TTRs averaging around six hours.  

Interestingly, Huntress noted a clear shift in ransomware tactics: rather than encrypting data, many attackers now opt to exfiltrate sensitive information and threaten to leak it unless a ransom is paid. This change is seen as a direct response to stronger ransomware defenses and increased law enforcement efforts, which led to the takedown of major groups like Lockbit. 

However, this shift presents new challenges for companies. While endpoint detection and ransomware protections have improved, the report points out that data loss prevention (DLP) measures remain underdeveloped. Linares noted that DLP solutions are often overlooked, especially in organizations with remote work and bring-your-own-device (BYOD) policies. These environments, he said, often lack the comprehensive monitoring and control needed to prevent data exfiltration. 

To stay ahead of these evolving threats, Huntress recommends that businesses not only strengthen their ransomware defenses but also implement more robust DLP strategies to protect sensitive data. As ransomware gangs continue to adapt, companies must be proactive in addressing both encryption and data theft risks.

Emerging Cybersecurity Threats in 2025: Shadow AI, Deepfakes, and Open-Source Risks

 

Cybersecurity continues to be a growing concern as organizations worldwide face an increasing number of sophisticated attacks. In early 2024, businesses encountered an alarming 1,308 cyberattacks per week—a sharp 28% rise from the previous year. This surge highlights the rapid evolution of cyber threats and the pressing need for stronger security strategies. As technology advances, cybercriminals are leveraging artificial intelligence, exploiting open-source vulnerabilities, and using advanced deception techniques to bypass security measures. 

One of the biggest cybersecurity risks in 2025 is ransomware, which remains a persistent and highly disruptive threat. Attackers use this method to encrypt critical data, demanding payment for its release. Many cybercriminals now employ double extortion tactics, where they not only lock an organization’s files but also threaten to leak sensitive information if their demands are not met. These attacks can cripple businesses, leading to financial losses and reputational damage. The growing sophistication of ransomware groups makes it imperative for companies to enhance their defensive measures, implement regular backups, and invest in proactive threat detection systems. 

Another significant concern is the rise of Initial Access Brokers (IABs), cybercriminals who specialize in selling stolen credentials to hackers. By gaining unauthorized access to corporate systems, these brokers enable large-scale cyberattacks, making it easier for threat actors to infiltrate networks. This trend has made stolen login credentials a valuable commodity on the dark web, increasing the risk of data breaches and financial fraud. Organizations must prioritize multi-factor authentication and continuous monitoring to mitigate these risks. 

A new and rapidly growing cybersecurity challenge is the use of unauthorized artificial intelligence tools, often referred to as Shadow AI. Employees frequently adopt AI-driven applications without proper security oversight, leading to potential data leaks and vulnerabilities. In some cases, AI-powered bots have unintentionally exposed sensitive financial information due to default settings that lack robust security measures. 

As AI becomes more integrated into workplaces, businesses must establish clear policies to regulate its use and ensure proper safeguards are in place. Deepfake technology has also emerged as a major cybersecurity threat. Cybercriminals are using AI-generated deepfake videos and audio recordings to impersonate high-ranking officials and deceive employees into transferring funds or sharing confidential data. 

A recent incident involved a Hong Kong-based company losing $25 million after an employee fell victim to a deepfake video call that convincingly mimicked their CFO. This alarming development underscores the need for advanced fraud detection systems and enhanced verification protocols to prevent such scams. Open-source software vulnerabilities are another critical concern. Many businesses and government institutions rely on open-source platforms, but these systems are increasingly being targeted by attackers. Cybercriminals have infiltrated open-source projects, gaining the trust of developers before injecting malicious code. 

A notable case involved a widely used Linux tool where a contributor inserted a backdoor after gradually establishing credibility within the project. If not for a vigilant security expert, the backdoor could have remained undetected, potentially compromising millions of systems. This incident highlights the importance of stricter security audits and increased funding for open-source security initiatives. 

To address these emerging threats, organizations and governments must take proactive measures. Strengthening regulatory frameworks, investing in AI-driven threat detection, and enhancing collaboration between cybersecurity experts and policymakers will be crucial in mitigating risks. The cybersecurity landscape is evolving at an unprecedented pace, and without a proactive approach, businesses and individuals alike will remain vulnerable to increasingly sophisticated attacks.

FunkSec Ransomware Group: AI-Powered Cyber Threat Targeting Global Organizations

 

A new ransomware group, FunkSec, has emerged as a growing concern within the cybersecurity community after launching a series of attacks in late 2024. Reports indicate that the group has carried out over 80 cyberattacks, signaling a strategic blend of hacktivism and cybercrime. According to recent findings, FunkSec’s activities suggest that its members are relatively new to the cyber threat landscape but have been using artificial intelligence (AI) to amplify their capabilities and expand their reach. 

FunkSec’s ransomware, developed using the Rust programming language, has caught the attention of security analysts due to its complexity and efficiency. Investigations suggest that AI tools may have been used to assist in coding and refining the malware, enabling the attackers to bypass security defenses more effectively. A suspected Algerian-based developer is believed to have inadvertently leaked portions of the ransomware’s code online, providing cybersecurity researchers with valuable insights into its functionality. 

Operating under a ransomware-as-a-service (RaaS) framework, FunkSec offers its malware to affiliates, who then carry out attacks in exchange for a percentage of the ransom collected. Their approach involves double extortion tactics—encrypting critical files while simultaneously threatening to publish stolen information unless the victim meets their financial demands. To facilitate their operations, FunkSec has launched an underground data leak website, where they advertise stolen data and offer additional cybercrime tools, such as distributed denial-of-service (DDoS) attack capabilities, credential theft utilities, and remote access software that allows for covert control of compromised systems. 

The origins of FunkSec date back to October 2024, when an online persona known as “Scorpion” introduced the group in underground forums. Additional figures, including “El_Farado” and “Bjorka,” have been linked to its expansion. Investigators have noted discrepancies in FunkSec’s communications, with some materials appearing professionally written in contrast to their typical informal style. This has led experts to believe that AI-generated content is being used to improve their messaging and phishing tactics, making them appear more credible to potential victims. 

FunkSec’s ransomware is designed to disable security features such as antivirus programs, logging mechanisms, and backup systems before encrypting files with a “.funksec” extension. The group’s ransom demands are relatively modest, often starting at around $10,000, making their attacks more accessible to a wide range of potential victims. Additionally, they have been known to sell stolen data at discounted rates to other threat actors, further extending their influence within the cybercriminal ecosystem. Beyond financial motives, FunkSec has attempted to align itself with hacktivist causes, targeting entities in countries like the United States and India in support of movements such as Free Palestine. 

However, cybersecurity analysts have expressed skepticism over the authenticity of their claims, noting that some of the data they leak appears to have been recycled from previous breaches. While FunkSec may be a relatively new player in the cyber threat landscape, their innovative use of AI and evolving tactics make them a significant threat. Security experts emphasize the importance of proactive measures such as regular system updates, employee training on cybersecurity best practices, and the implementation of robust access controls to mitigate the risks posed by emerging ransomware threats like FunkSec.

Play Ransomware Threat Intensifies with State-Sponsored Links and Advanced Tactics

 

Play ransomware continues to be a formidable cybersecurity threat, with over 300 successful attacks reported globally since its first detection in 2022. Named for the “.PLAY” extension it appends to encrypted files, this ransomware has been linked to Andariel, a North Korean state-sponsored hacking group operating under the Reconnaissance General Bureau. 

This connection highlights the increasing involvement of state-backed actors in sophisticated cybercrime campaigns targeting both public and private sector organizations worldwide. Recent analysis by AhnLab sheds light on how Play ransomware gains access to its victims’ networks. The attackers exploit vulnerabilities in widely used software systems or misuse valid user accounts. 

Known flaws in Microsoft Exchange Server’s ProxyNotShell vulnerabilities (CVE-2022-41040 and CVE-2022-41082) and Fortinet’s FortiOS (CVE-2020-12812 and CVE-2018-13379) have been frequently abused by these attackers. After infiltrating a network, they use port scanning techniques to gather information about active systems and services, collect Active Directory data, and identify paths for privilege escalation. These escalated privileges allow the attackers to obtain administrator-level access, steal credentials, and ultimately gain control over the domain environment. 

One of the key challenges in detecting Play ransomware lies in its ability to blend malicious activities with legitimate operations. The attackers often use tools like Process Hacker to disable security products. Many of these tools are not inherently malicious and are commonly used for legitimate purposes, making it difficult for security systems to distinguish between normal and nefarious activities. This ability to evade detection underscores the sophistication of Play ransomware and its operators. 

The impact of a Play ransomware attack goes beyond encryption. Like many modern ransomware variants, Play uses double-extortion tactics, exfiltrating sensitive data before locking systems. This exfiltrated data is then leveraged to pressure victims into paying ransoms by threatening to leak the information on dark web forums. The combination of system disruption and the risk of public data exposure makes Play ransomware particularly damaging to its targets. To mitigate the risks posed by Play ransomware, cybersecurity experts and the Federal Bureau of Investigation (FBI) recommend implementing proactive defenses. 

Organizations should ensure that software, operating systems, and firmware are regularly updated to address vulnerabilities. Phishing-resistant multi-factor authentication (MFA) is crucial to reduce the risk of unauthorized access, while employee training on recognizing phishing attempts remains essential. Additionally, network segmentation can limit the attackers’ ability to move laterally, reducing the overall impact of an attack. 

Play ransomware illustrates the evolving complexity of cyber threats, particularly those linked to state-sponsored groups. Its reliance on exploiting known vulnerabilities, combined with its use of legitimate tools, highlights the critical need for organizations to adopt comprehensive cybersecurity measures. By prioritizing vulnerability management, user education, and proactive defenses, organizations can better protect themselves against the ongoing threat posed by Play ransomware and similar cyber campaigns.
