Session Hijacking

Session hijacking is a cyberattack technique where an attacker intercepts or takes control of an authenticated user session, typically by stealing session tokens or cookies. This threat is particularly relevant to AI governance because enterprise AI systems often process sensitive data and require robust access controls to maintain compliance with regulations like HIPAA and SOC 2. Organizations must implement secure session management practices, encryption protocols, and real-time monitoring to prevent unauthorized access to AI platforms and the confidential information they handle.

Infostealer Malware Bypasses MFA to Hijack Claude Accounts

Anthropic has disclosed that infostealer malware families including Vidar, LummaC2, StealC, RedLine, and Atomic Stealer are stealing authenticated browser session tokens to access Claude accounts without requiring passwords or multi-factor authentication. The company is revoking compromised sessions, removing saved payment methods, and issuing refunds for unauthorized charges it can identify. Enterprise compliance teams face a post-authentication access risk that standard AI platform credential controls do not address.
