REvil ransomware gang arrested in Russia

Authorities in Russia say they have dismantled the ransomware crime group REvil and charged several of its members.

The United States had offered a reward of up to $10m (£7.3m) for information leading to the gang members, following ransomware attacks.

Russia's intelligence bureau FSB said the group had "ceased to exist".

However, it does not appear that any Russian members of the gang will be extradited to the United States.

The agency said it had acted after being provided with information about the REvil gang by the US.
