During routine Dark Web Monitoring activities, Our Threat Intelligence Team identified a newly active ransomware operation calling itself The Green Blood Group. The group operates a dedicated Tor-based leak site and follows a double-extortion model, threatening public disclosure of victim data when negotiations fail. The screenshot shown above captures the group’s Tor portal in its current state.

CVE-2026-24858 is a critical authentication bypass vulnerability(CWE-288: Authentication Bypass Using an Alternate Path or Channel) in Fortinet products. It affects FortiOS, FortiAnalyzer, FortiManager, and potentially FortiProxy. An attacker with a FortiCloud account and registered device can log into devices registered to other accounts if FortiCloud SSO is enabled. Disclosed January 27, 2026, as actively exploited zero-day. CVSS 9.4 (some sources cite 9.8).

Let’s be honest: in 2026, the traditional “firewall” is a bit of a relic. Having spent years analyzing how threat actors operate, I can tell you they aren’t banging on your front door anymore. Why would they? It’s much easier to build a pixel-perfect replica of your front door down the street and trick your customers into handing over their keys there.

CVE-2026-23745 is a high-severity path traversal flaw in node-tar (the tar library for Node.js). Versions ≤7.5.2 fail to sanitize linkpath in hardlink and symlink entries when preservePaths is false (default secure mode). Malicious tar archives bypass extraction root restrictions, enabling arbitrary file overwrite via hardlinks and symlink poisoning via absolute targets. Discovered January 2026, patched in 7.5.3. Impacts npm ecosystems, CI/CD pipelines, and apps extracting untrusted archives.

CVE-2025-34299 is a critical vulnerability in Monsta FTP, a web-based file transfer tool, unauthenticated arbitrary file write via remote download leading to remote code execution (RCE). Affecting versions 2.11 and earlier, it enables attackers to upload malicious files via a crafted SFTP or FTP connection, compromising servers without credentials. This flaw has seen active exploitation through opportunistic scans. By January 2026, Vulnerable instances remain exposed.
