This AI company leaked its own code. It's also built something terrifying

A hacking group claims to have broken into the flood defence system protecting Venice's Piazza San Marco - and is offering to sell access to whoever wants it. The asking price? A frankly insulting $600. Meanwhile, Anthropic accidentally leaked the source code for Claude Code via a basic packaging mistake. Oh, and by the way, they've also just revealed they've built an AI model called Mythos that can find and chain together software vulnerabilities faster than any human. Sleep well. All this and more in episode 463 of the “Smashing Security” podcast with cybersecurity expert and keynote speaker Graham Cluley, joined this week by special guest Tanya Janca.
