On 24 March 2026, two versions of the litellm Python package on PyPI were found to contain malicious code.  The packages (versions 1.82.7 and 1.82.8) were published by a threat actor known as TeamPCP after they obtained the maintainer's PyPI credentials through a prior compromise of Trivy, an open source security scanner used in litellm's CI/CD pipeline.

The malicious versions were available for approximately three hours before PyPI quarantined the package. litellm is downloaded roughly 3.4 mill

Throughout early 2026, SentinelOne’s® Digital Forensics & Incident Response (DFIR) team has responded to several incidents in which FortiGate Next-Generation Firewalls (NGFW) have been compromised to establish a foothold in the targeted environment.  Each incident was detected and stopped during the lateral movement phase of the attack.  Fortinet disclosed and issued patches for several high-severity vulnerabilities, allowing unauthorized access during our investigation period.  Successful explo

North Korea's state-sponsored Lazarus Group has added yet another ransomware strain to its arsenal. New research from the Symantec and Carbon Black Threat Hunter Team reveals that the group has been observed deploying Medusa ransomware in an attack against an unnamed entity in the Middle East and, separately, attempting an unsuccessful breach of a healthcare organization in the United States.  The findings represent a notable evolution in Lazarus's tactics. The group has previously been linked t

FortiGuard Labs recently observed several targeted phishing campaigns in Taiwan that use themes designed to exploit local business processes.  These campaigns disseminate Winos 4.0 (ValleyRat) and subsequent malicious plugins through weaponized attachments or embedded links.  The lures mimic official communications, such as tax audit notifications, tax filing software installers, and cloud-based e-invoice downloads.

While analyzing one of the affiliate programs, Doctor Web’s researchers discovered a unique piece of malware with clicker functionality and called it a Trojan.ChimeraWire. This malware targets computers running Microsoft Windows and is based on the open-source projects zlsgo and Rod for automated website and web application management.

Trojan.ChimeraWire allows cybercriminals to simulate user actions and boost a website's behavioral ranking by artificially increasing its search engine rankings.

At the end of October, during a global disruption of AWS connections, FortiGuard Labs observed malware named “ShadowV2” spreading via IoT vulnerabilities.  These incidents affected multiple countries worldwide and spanned seven different industries.  To date, the malware appears to have been active only during the large-scale AWS outage.  Researchers believe this activity was likely a test run conducted in preparation for future attacks.  The following article provides a detailed analysis of the
