Researchers at the University of Toronto have built a worm that thinks for itself. Using free off-the-shelf AI models it works out how to break into each new computer it encounters, and hijacks the powerful ones to host its own AI brain. And then the researchers discovered their creation had quietly removed the list of machines it wasn't supposed to attack. Meanwhile, Meta's shiny new AI customer support agent has been cheerfully helping hackers help themselves to other people's Instagram accounts.

All this and more in episode 471 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest James Ball.

A 23-year-old radio enthusiast spent £300 on a piece of kit from the internet, and used it to bring four packed high-speed trains to a screeching halt. His defence in court? Possibly the most creative excuse we've heard all year. Meanwhile, owners of $4,000 robot lawnmowers are discovering that their gadget can be hijacked over the internet, redirected at journalists who foolishly lie down in front of it, and used to harvest Wi-Fi passwords, email addresses, and GPS coordinates. Change the default password? Sure - until the next firmware update silently resets it back. Plus - don't miss our featured interview with XBOW's Brendan Dolan-Gavitt about how AI is transforming penetration testing.
