A cyber-crime kingpin in a US prison speaks for the first time. How did he dodge the FBI when they came to his home? And how did he and his alleged crime gang steal millions of dollars from their victims? We learn that Jabber Zeus boss Tank had friends in high political places in Ukraine – and a budding young business associate in Russia.

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 Eastern and Southern Europe correspondent Sarah Rainsford, who spent more than two decades reporting from Moscow.
