Episode notes
AI Agent That Fixes Code Vulnerabilities
- Google DeepMind's CodeMender autonomously finds and fixes classes of software vulnerabilities using Gemini models and multi-agent validation.
- It has delivered 72 fixes to large open-source projects in six months with human review before submission.
Use California's New Universal Opt-Out
- California now requires browsers to offer a universal one-click opt-out for third-party data sales for residents.
- Californians should enable the browser opt-out and review social accounts to ensure full data deletion on cancellation.
Legitimate Tools Weaponized For Stealthy Attacks
- Attackers repurpose legitimate open-source tools like Nezha to reduce detection risk and research cost when compromising networks.
- This trend enables widespread compromises across regions, as seen in over 100 affected organizations since August.
