AI Just Became the World's Best Hacker

Anthropic just announced something that should make every founder sit up and pay attention: their new AI model, Claude Mythos, can autonomously find and exploit zero-day vulnerabilities in every major operating system and every major web browser. We're not talking about theoretical weaknesses — the model wrote a fully working exploit for a 17-year-old FreeBSD bug that grants root access to unauthenticated users, with zero human involvement after the initial prompt. It found a 27-year-old bug in OpenBSD, an operating system famous for its security. And non-security-experts asked it to find vulnerabilities overnight and woke up to complete, working exploits the next morning.Chris and David dig into what this means for the cybersecurity landscape and for startups in particular. They explore the massive leap from Anthropic's previous model — which had near-zero success at exploit development — to Mythos Preview, which succeeded 181 times on the same benchmark. They debate Anthropic's decision to withhold the model from public release through "Project Glasswing," sharing it only with critical infrastructure partners, and whether that approach protects the ecosystem or just delays the inevitable arms race between AI-powered attackers and defenders.For entrepreneurs building software products, the implications are immediate and practical. The window between a vulnerability being publicly disclosed and an AI turning it into a working exploit is shrinking to hours. Patch cycles need to accelerate, security testing needs to level up, and the old startup excuse of "we're too small to be a target" just became dangerously outdated. This episode breaks down exactly what founders should be doing right now to prepare for a world where AI is both the lock and the lockpick.
