Episode Details

Anthropic's Claude found a genuine cryptographic weakness in a post-quantum signature scheme that two years of expert review missed, plus a new attack on round-reduced AES. Microsoft became the fourth major lab to ship cyber capability as a separately gated model, joining OpenAI, Anthropic, and Google in treating defensive AI as its own access-controlled product line. Meanwhile OpenAI and Nvidia's new security alliance are both racing to standardize the harness layer that sits between models and the actions they're allowed to take.
