"The January snow lay thick on the Moscow ground, as masked officers of the FSB - Russia's fearsome security agency - prepared to smash down the doors at one of 25 addresses they would raid that day.
Their target was REvil, a shadowy conclave of hackers that claimed to have stolen more than $100m (£74m) a year through "ransomware" attacks, before suddenly disappearing.
As group members were led away in cuffs, FSB officers gathered crypto-wallets containing untold volumes of digital currency such as bitcoin. Others used money-counting machines to tot up dozens of stacks of hundred dollar bills."
"Ukraine has been hit by a "massive" cyber-attack, with the websites of several government departments including the ministry of foreign affairs and the education ministry knocked out.
