Google Groups Used to Deliver Lumma Stealer & Ninja Browser
🔒 CTM360 reports attackers are abusing Google Groups and Google-hosted redirectors to distribute credential-stealing malware, leveraging over 4,000 malicious groups and 3,500 hosted URLs to target organizations worldwide. The campaign uses industry-focused posts and shortened or Docs/Drive redirect links to lure victims and deliver OS-specific payloads. On Windows, victims receive a padded archive that reconstructs an AutoIt-based loader and a memory-resident Lumma infostealer; on Linux, users are served a trojanized Chromium-branded "Ninja Browser" with covert extensions and silent persistence. CTM360 advises inspecting redirect chains, blocking IoCs, auditing browser extensions, and monitoring scheduled tasks and endpoint activity.
