Moscow drag racers, an opulent Russian wedding and a malware code named after the Greek god of thunder - how do they all connect? A cyber-sleuth and “dark hero of the internet” Lawrence Baldwin sees signs of an emerging underworld. As money vanishes from accounts across the US, Lawrence follows the trail, infiltrating the gang - holding out for clues. But who are these audacious hackers?

Hosted by Joe Tidy, the BBC’s cyber correspondent, one of the few Western journalists to have met an alleged member of Evil Corp, and Sarah Rainsford, who spent more than two decades reporting from Moscow.
