Google Chrome 2026: Device Bound Session Credentials Enhance Security Against Infostealer Threats
In April 2026, Google introduced Device Bound Session Credentials (DBSC) in Chrome 146 for Windows, aiming to combat the escalating threat of session cookie theft by infostealer malware. DBSC cryptographically binds authentication sessions to a user's specific device using hardware-backed security modules like the Trusted Platform Module (TPM). This binding ensures that even if session cookies are exfiltrated, they cannot be utilized on unauthorized devices, thereby mitigating unauthorized access to user accounts. ([security.googleblog.com](https://security.googleblog.com/2026/04/protecting-cookies-with-device-bound.html?utm_source=openai)) The deployment of DBSC is particularly timely given the rise of sophisticated infostealer malware, such as LummaC2, which harvests session cookies to bypass traditional authentication mechanisms, including multi-factor authentication (MFA). By rendering stolen session cookies ineffective on unauthorized devices, DBSC addresses a critical vulnerability in current web authentication practices.
