Email Essentials: Securing Communication

In episode 426 of the "Smashing Security" podcast, Graham reveals how you can hijack a train’s brakes from 150 miles away using kit cheaper than a second-hand PlayStation.

Meanwhile, Carole investigates how Grok went berserk, which didn't stop the Department of Defense signing a contract with Elon’s AI chatbot. So who is responsible when your chatbot becomes a bigot?

Plus: Email headaches, SPF rage, and a glowing review for... Taskmaster SuperMax Plus?

All this and more is discussed in the latest edition of the "Smashing Security" podcast by cybersecurity veterans Graham Cluley and Carole Theriault.
