Hackers Steal Sessions, Bypass All Logins
8 Apr
Summary
- Storm malware steals session cookies, bypassing passwords and MFA.
- Data is processed server-side, evading endpoint security detection.
- Malware sold as a subscription service, lowering cybercrime entry barriers.

A novel infostealer malware, identified as Storm, has emerged, fundamentally altering account compromise tactics. This malware targets session cookies, enabling attackers to bypass password requirements and even multi-factor authentication, thereby hijacking legitimate user sessions remotely. Storm operates server-side, processing encrypted browser data including credentials and session tokens for both Chromium and Gecko-based browsers. This stealthy approach diminishes visibility for endpoint security solutions by avoiding local decryption of sensitive information.
