The net tightens on the Jabber Zeus crew. Police and intelligence services across borders are poised to synchronise raids, but cops in London are thrown a last-minute curveball that could see the whole operation implode.

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.
