Three Buddy Problem - Episode 115: We into Anthropic's Frontier Red Team fear-mongering on Zhipu's open-weight GLM 5.3 model and wonder why the AI labs' cyber programs do so little for defenders.
Plus, Citrix NetScaler zero-days, a new iOS zero-day tied to WhatsApp, AI agents that act on your behalf, and whether security teams should buy DGX Sparks to run models locally.
Cast: Juan Andres Guerrero-Saade, Ryan Naraine and Costin Raiu.
