Cyble Details DOGE Big Balls Ransomware Campaign - A new ransomware operation, DOGE BIG BALLS Ransomware, uses a finance-themed ZIP file to deliver a kernel-mode exploit tool and reconnaissance modules, employing psychological manipulation and attempting to misdirect attention.
Cyble Research and Intelligence Labs (CRIL) has uncovered a new ransomware operation dubbed "DOGE BIG BALLS Ransomware." This campaign uses a finance-themed ZIP file named "Pay Adjustment.zip" to trick users into executing malicious shortcut files. These files then trigger multi-stage PowerShell scripts, ultimately delivering custom payloads that include a kernel-mode exploit tool and reconnaissance modules. The ransomware itself is a modified version of Fog, further customized with a provocative name that references a known public figure.

The attention-grabbing name is likely a deliberate attempt to misdirect attention and create confusion, potentially questioning the effectiveness of governmental cybersecurity efforts. Despite the name's provocative nature, the attack mechanism is relatively simple. The ransomware is typically distributed via a compressed ZIP file, sometimes disguised as a PDF document. Once opened, the malicious payload bypasses traditional security defenses using obfuscation and anti-detection techniques.

The DOGE Big Balls ransomware attack highlights the evolving tactics of cybercriminals, blending technical sophistication with psychological manipulation. It also demonstrates the increasing trend of ransomware attacks targeting the healthcare sector, as seen with the recent attack on DaVita, a Denver-based dialysis firm. This incident underscores the critical need for organizations to bolster their cybersecurity defenses and incident response capabilities to protect sensitive data and maintain operational continuity.

EDR and AV Solutions Miss Two-Thirds of Malware Infections - SpyCloud's study indicates that 66% of malware infections bypass EDR and antivirus solutions, highlighting the need for enhanced detection methods to address sophisticated tactics used by threat actors.
SpyCloud has released new research indicating a significant gap in the effectiveness of endpoint detection and response (EDR) and antivirus (AV) solutions. According to their analysis of recaptured darknet data, a staggering 66% of malware infections occur on devices that already have endpoint security solutions installed. This highlights the increasing ability of threat actors to bypass traditional security measures.

The report emphasizes that modern infostealer malware employs sophisticated tactics to evade detection, even by EDR solutions with advanced AI and telemetry analysis. These tactics include polymorphic malware, memory-only execution, and exploiting zero-day vulnerabilities or outdated software. Data from 2024 showed that nearly one in two corporate users were victims of malware infections, and in the prior year, malware was the cause of 61% of all breaches.

Damon Fleury, Chief Product Officer at SpyCloud, stated that the consequences of undetected malware infections can be "catastrophic." He emphasized the ongoing "arms race" where attackers constantly evolve their techniques to avoid detection. SpyCloud aims to provide a crucial line of defense by uncovering infostealer infections that slip past EDR and AV solutions, detecting when stolen data surfaces in the criminal underground, and automatically feeding this intelligence back to EDRs to facilitate quarantine and remediation.

Hunters International Shifts to Data Extortion - Hunters International, a ransomware-as-a-service (RaaS) group, has shifted its focus from ransomware to data extortion, rebranding itself as "World Leaks."
The Ransomware-as-a-Service (RaaS) group Hunters International has reportedly shifted its focus from ransomware to data extortion, rebranding itself as "World Leaks" on January 1, 2025. This change in tactics signals a new era in cybercrime, driven by the declining profitability of ransomware and increased scrutiny from law enforcement and governments worldwide. Group-IB researchers revealed that the group's senior personnel decided ransomware was becoming too "unpromising, low-converting, and extremely risky," leading to the development of an extortion-only operation.

The group is reportedly leveraging custom-built exfiltration tools to automate data theft from victim networks, enhancing their ability to carry out extortion-only attacks. Cybersecurity researchers have also linked Hunters International to the infamous Hive ransomware group. There are suggestions that they acquired Hive’s source code and operational tools. While Hunters International denies being a direct continuation of Hive, evidence suggests that they acquired Hive’s source code and operational tools. The group targets various industries, including healthcare, real estate, and professional services, across North America, Europe, and Asia.

EvilCorp Ties with RansomHub Actively Exploited - EvilCorp, a sanctioned Russia-based cybercriminal enterprise, is linked to RansomHub ransomware through shared tactics and malware like SocGholish, which uses fake browser updates for initial access, posing a dilemma for victims due to potential US Treasury fines for ransom payments.
EvilCorp, a Russia-based cybercriminal enterprise already under sanctions, has been linked to the RansomHub ransomware operation, indicating a concerning level of cooperation between the two groups. Intelligence sources confirm that EvilCorp and RansomHub are actively sharing intrusion methods, indicators of compromise (IOCs), and tactics, techniques, and procedures (TTPs). This collaboration poses a significant threat as it combines the capabilities of a sanctioned entity known for large-scale financial cyberattacks with a prominent ransomware-as-a-service (RaaS) operation. RansomHub, active since February 2024 and reportedly run by Russian-speaking cybercriminals, has become increasingly popular among former affiliates of other RaaS platforms such as ALPHV/BlackCat and LockBit.

One of EvilCorp's signature TTPs involves the use of SocGholish JavaScript malware, also known as FAKEUPDATES, to gain initial access to systems. This malware employs drive-by downloads disguised as web browser software updates. Once a system is infected with SocGholish, EvilCorp affiliates can then deploy the RansomHub ransomware. Given the sanctions imposed on EvilCorp since 2019, organizations that fall victim to this attack face a difficult dilemma: paying the ransom is illegal and can lead to substantial fines from the US Treasury’s Office of Foreign Assets Control. This situation is further complicated by the fact that EvilCorp affiliates are known to rebrand their ransomware and become affiliates of other RaaS operations.

The partnership between EvilCorp and RansomHub highlights the evolving and increasingly complex nature of the cybercrime landscape. Maksim Yakubets, a figure reportedly at the helm of EvilCorp, has a long-standing involvement in high-profile hacking campaigns and has been connected to the LockBit ransomware and the Dridex Banking Trojan. The use of Microsoft Teams and other tools to spread malware via vishing scams further demonstrates the diverse range of tactics employed by these threat actors. Cybersecurity experts advise organizations to be vigilant, monitor for PowerShell commands in Teams messages, and investigate any unusual use of Quick Assist or signed binaries running from unexpected locations.

Ransomware Gangs Accelerate Encryption Timelines - Ransomware gangs are accelerating operations, with the average time-to-ransom now at 17 hours, employing advanced evasion and data extortion strategies.
Ransomware gangs are accelerating their operations, significantly reducing the time between initial system compromise and encryption deployment. Recent cybersecurity analyses reveal the average time-to-ransom (TTR) now stands at a mere 17 hours. This marks a dramatic shift from previous tactics where attackers would remain hidden within networks for extended periods to maximize reconnaissance and control. Some groups, like Akira, Play, and Dharma/Crysis, have even achieved TTRs as low as 4-6 hours, demonstrating remarkable efficiency and adaptability.

This rapid pace presents considerable challenges for organizations attempting to defend against these attacks. The shrinking window for detection and response necessitates proactive threat detection and rapid incident response capabilities. The trend also highlights the increasing sophistication of ransomware groups, which are employing advanced tools and techniques to quickly achieve their objectives, often exploiting vulnerabilities in remote monitoring and management tools or using initial access brokers to infiltrate networks, escalate privileges, and deploy ransomware payloads.

Kimsuky Hackers Employ Custom RDP Wrapper for Access - Kimsuky APT employs custom RDP wrappers and proxy tools with spear-phishing tactics to gain unauthorized access for persistent cyber espionage.
The North Korean hacking group Kimsuky has been observed in recent attacks employing a custom-built RDP Wrapper and proxy tools to directly access infected machines. A new report by AhnLab's ASEC team details additional malware used by Kimsuky in these attacks, highlighting the group's intensified use of modified tools for unauthorized system access. This cyber espionage campaign begins with spear-phishing tactics, distributing malicious shortcut files disguised as legitimate documents to initiate the infection chain.

These files, often disguised as PDFs or Office documents, execute commands via PowerShell or Mshta to download malware such as PebbleDash and the custom RDP Wrapper, enabling remote control of compromised systems. Kimsuky's custom RDP Wrapper, a modified version of an open-source utility, includes export functions designed to evade detection by security software, facilitating stealthy remote access. In environments where direct RDP access is restricted, Kimsuky deploys proxy malware to bypass network barriers, maintaining persistent access and employing keyloggers and information-stealing malware to exfiltrate sensitive data.
