An anonymous reader writes: The author of the original Petya ransomware — a person/group going by the name of Janus Cybercrime Solutions — has released the master decryption key of all past Petya versions. This key can decrypt all ransomware families part of the Petya family except NotPetya, which isn’t the work of Janus, but is believed to be the work of a nation-state actor that targeted Ukraine.
