Cybersecurity Firms Report Record-Breaking Quarter for Ransomware Attacks
Several cybersecurity companies have released Q1, 2025 reports on the current state of ransomware, and while the figures vary across the different reports due to different methodologies for tracking ransomware activity, there is consensus that the year so far has been a record-breaker with a historic high in terms of new victims. There has also been a significant increase in active ransomware groups due to the fragmentation of the ransomware landscape, with many more smaller groups emerging as seasoned affiliates of previously dominant ransomware-as-a-service (RaaS) choose their own paths. The BlackFog State of Ransomware 2025 report shows a record-breaking number of ransomware attacks disclosed by victims in Q1, 2025. BlackFog tracked 278 disclosed incidents in Q1, 2025, up 45% from Q1, 2024. BlackFog said March set a new record with 107 disclosed attacks, following on from new records set in January and February, which were up 22% and 36% respectively from Q1, 2024. Healthcare Continues to be Top Target for Ransomware Groups As has been the case in previous quarters, healthcare...

Windows CLFS Flaw Being Actively Exploited by Ransomware Group
Microsoft has patched a vulnerability in the Windows Common Log File System (CLFS) that is being actively exploited by a threat actor tracked as Storm-2460 after first deploying PipeMagic malware. The malware is used to exploit the flaw to elevate privileges to facilitate the widespread deployment of ransomware on victims’ systems. Windows CLFS is a logging system used for managing transactional records. The vulnerability is tracked as CVE-2025-29824 and is a use-after-free vulnerability affecting the CLFS kernel driver. The vulnerability has been assigned a CVSS base score of 7.8 (high severity), as it cannot be remotely exploited without first compromising a vulnerable system. PipeMagic malware was first identified in 2022 and provides a backdoor into compromised systems and serves as a gateway. The malware has previously been used to facilitate the exploitation of other vulnerabilities and has been observed being delivered via a fake ChatGPT application, although the initial access vector used in the latest attacks has yet to be determined. Microsoft has observed the...
Lawsuit Filed Against Teaching Hospital Over Pharmacist’s Decade-long Cyber-Spying Campaign
A class action lawsuit has been filed against University of Maryland Medical System Corporation and University of Maryland Medical Center (UMMC) by six current and former employees who claim they were victims of cyber-voyeurism and cyber stalking by a former UMMC pharmacist. The lawsuit names six Jane Doe plaintiffs, and was filed individually and on behalf of similarly situated individuals. According to the lawsuit, the former UMMC pharmacist Matthew Bathula installed keylogging software on approximately 400 laptops and workstations in clinics, treatment rooms, laboratories, and other locations at UMMC over the course of a decade. The spyware granted him access to the devices without requiring his credentials and allowed him to obtain the credentials of at least 80 staff members. The keylogger recorded keystrokes on devices as they were entered and allowed him to obtain credentials for personal accounts, including email accounts, financial accounts, dating apps, home surveillance systems, and more. The lawsuit claims he learned username and password patterns from the spyware,...
