Hackers who targeted Ukraine clean out bitcoin ransom wallet

'NotPetya' ransomware creators move 8,000 in bitcoin, leaving observers uncertain over the attack's motive

The hackers behind the NotPetya ransomware, which wiped computers in more than 60 countries in late June, have moved more than 8,000 worth of bitcoins out of the account used to receive the ransoms.

The transfer has added credence to messages purporting to be from the attackers offering to decrypt every single infected computer for a one-off payment of 200,000, after security researchers suggested they may be state-sponsored actors.
