Author of Original Petya Ransomware Publishes Master Decryption Key

This key can decrypt all ransomware families part of the Petya family except NotPetya...This list includes:
* First Petya ransomware version (flashed white skull on red background during boot-up screens)
* Second Petya version that also included Mischa ransomware (flashed green skull on black background during boot-up screens)
* Third Petya version, also known as GoldenEye ransomware (flashed yellow skull on black background during boot-up screens)

...The key will only help those victims who cloned their drives and saved a copy of the encrypted data.

...This key won't help NotPetya victims because the NotPetya ransomware was created by "pirating" the original Petya ransomware and modifying its behavior by a process called patching. NotPetya used a different encryption routine and was proven to have no connection to the original Petya...

It seems that Hasherezade has added a decoder for Petya RED / GREEN / GOLDENEYE with the resulting master key.

I checked the decoding of the RED, GREEN, GOLDENEYE snapshots.

Antipetya_ultimate CD did not work for me on virtual snapshots,

but with the help of the utility petya_key_v0.1_win32 I got the decryption keys and the decryption was successful.

 

Congratulations to Hasherezade on the great work done!
