Smashing Security podcast #468: High-speed train hacks and homicidal lawnmowers

Graham Cluley @ 12:04 am, May 21, 2026  @grahamcluley.com  / grahamcluley 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. All this and more in episode 468 of the “Smashing Security” podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Geoff White.
