Alleged attacks and disputed responsibility

As the cyber criminals reinvent themselves, FBI Special Agent Keith Mularski goes undercover to infiltrate the operation. But as kingpin Tank is finally arrested, another leader rises with the creation of a new crew: Evil Corp. The group’s alleged leader, Maksim Yakubets, would go on to steal millions using “one of the most prolific and successful malware strains” in the history of cyber-crime.

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 the BBC’s Sarah Rainsford, who spent more than two decades reporting from Moscow.
