Protecting Cookies with Device Bound Session Credentials

Google has announced the public availability of Device Bound Session Credentials (DBSC) for Windows users on Chrome 146, with macOS support coming soon. This initiative aims to combat session theft, which typically occurs when malware extracts session cookies from browsers. DBSC works by cryptographically binding authentication sessions to specific devices using secure hardware modules, ensuring that exfiltrated cookies quickly expire and become unusable. The protocol is designed to prioritize user privacy, preventing cross-site tracking. Google collaborated with the web community on DBSC’s development and plans to enhance its capabilities for enterprise environments and broader device support in the future.

Google Workspace’s continuous approach to mitigating indirect prompt injections

Adam Gavish from Google’s GenAI Security Team discusses indirect prompt injection (IPI) as a growing threat to AI applications like Workspace with Gemini. Attackers can manipulate AI behavior by embedding malicious instructions within data sources, sometimes without user input. Google employs a multi-faceted strategy to enhance defenses against IPI, including proactive attack discovery, red-teaming simulations, a vulnerability rewards program, and synthetic data generation. They focus on improving LLMs to better identify harmful commands while ensuring operational efficiency. Ongoing defense refinement involves updating configurations, retraining models, and extensive testing to validate improvements. Google’s commitment to AI security emphasizes a robust, agile response to evolving threats, aiming to provide a safe user experience in AI-first environments.
