Hacking the hackers: How cyber gang Lockbit were 'locked out'

One of the world's most prolific cyber crime gangs has been taken down by law enforcement agencies including the FBI, Europol and the UK's National Crime Agency.

Lockbit is an extortion website that held its victims’ data for ransom – some of biggest UK bodies affected were the Royal Mail and the NHS.

Five Russian nationals have been charged by US authorities and dozens of crypto accounts frozen.

On the Sky News Daily Niall Paterson is joined by science and technology editor Tom Clarke and crime correspondent Martin Brunt to discuss who Lockbit are, Operation Cronos and what this means for other cyber gangs.
