Google Chrome Rolls Out Advanced Session Binding: Eliminating Cookie Theft Account Takeovers

Cryptographically Binding Web Sessions to Hardware Security Modules

Google Chrome has deployed a groundbreaking security feature known as Device Bound Session Credentials (DBSC). The protocol binds active web session cookies directly to the user's hardware Trusted Platform Module (TPM) or Secure Enclave.

Infostealer malware has increasingly targeted browser cookie databases to bypass multi-factor authentication (MFA). DBSC renders stolen session tokens useless on unauthorized secondary devices by requiring local cryptographic proof per request.

Neutralizing Infostealer Malware and Hijacked Session Token Exploits

Security analysts have hailed DBSC as the single most effective browser security advancement in a decade, virtually eliminating session hijacking for participating web services.
