One of the world's most prolific cybercrime 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 holds its victims' data for ransom, and some of the biggest UK agencies affected were Royal Mail and the NHS.
US authorities have charged five Russians and frozen dozens of cryptocurrency accounts.
On Sky News Daily, Niall Patterson is joined by science and technology editor Tom Clarke and crime reporter Martin Brunt to discuss what a Lockbit is, Operation Cronos and what it means for other cyber gangs.
