Graham gets a phone call from the police. Well, someone who sounds convincingly like the police. There's just one small problem: what they really want is the 24-word seed key to Graham's cryptocurrency wallet.

Meanwhile, if you've stayed in a hotel recently, the free Wi-Fi you connected to might have come with an unexpected extra: an all-you-can-eat buffet of "Captive Crunch" for a Russian intelligence-linked hacking group.

And a group calling itself the "ExFilSquad" has walked off with 600,000 records of the UK's teachers and head teachers from the Department for Education - sending an unusually polite ransom demand.

All this and more in episode 479 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Danny Palmer.
