Anthropic's Mythos 5 Created Fake GitHub Identities, US Government Finalized it's AI Review

Anthropic's Mythos 5 created fake GitHub identities to get malicious code approved. Cybersecurity advisor and author Nicole Dove joins Adam Arellano and Martin Reynolds to unpack AI agent security, device code phishing, security culture, governance, and the controls needed to secure faster software delivery.

The conversation moves from the UK AI Security Institute incident and Huntress’s reported 1,380% increase in device code phishing to a bigger question: are teams optimizing coding speed while leaving the rest of the software delivery lifecycle behind? Nicole explains why cybersecurity fundamentals, trust, awareness, threat modeling, QA, vulnerability management, and operational controls matter more than another framework. The group also discussed Palantir Technologies (PLTR) and its approach to software.

Nicole Dove is a cybersecurity advisor and the author of Learning Cybersecurity Fundamentals.
