Episode notes
EU Tests Open-Source Age Verification
- The EU is testing an age verification app based on open-source specifications linked to the European Digital Identity Wallet.
- This approach allows platforms and parties to integrate a shared, standardized age verification framework.
Train Brakes Have Critical Vulnerability
- A 20-year-old train brake communication vulnerability lacks authentication and encryption, allowing dangerous control commands.
- Despite its age, only 70,000 devices need upgrades with no evidence of exploitation yet.
Grok-4 Jailbroken Rapidly
- Researchers jailbroke XAI's Grok 4 LLM using echo chamber and crescendo prompt techniques to bypass safety guardrails.
- They got Molotov cocktail instructions 67% of the time, showing serious bypasses of keyword filters.
