Google is introducing a new prototype feature called 'Device Bound Session Credentials' in the Chrome browser to enhance security against cookie theft by hackers. The system will utilize encryption keys to secure a user’s login sessions, ultimately aiming to establish it as a new open web standard. Internet cookies, which store website preferences including authentication details, are vulnerable to theft by malware after login, bypassing two-factor authentication and antivirus detection. To combat this, Google intends to bind the authentication cookies to the user’s PC using public key cryptography and store them within a TPM chip on Windows devices. This approach will substantially reduce the success rate of cookie theft malware and, if successful, will be extended to Mac and Linux devices. The company plans to run trials of the prototype and engage with website developers and users in the near future to enhance overall account security. Despite the privacy concerns, the DBSC system is receiving support from third-party companies and aims to present a standard that preserves privacy while ensuring security against cookie theft.
