RakhniDecryptor is a general purpose ransomware decryptor created by Kaspersky Labs. Instead of creating a separate decryptor for each ransomware infection, they created on decryptor that can handle a variety of different families.

A guide explaining how to use the RakhniDecryptor can be found here: Kaspersky Releases Decryptor for the Dharma Ransomware.

Currently RakhniDecryptor can decrypt the following ransomware families:

  Trojan-Ransom.Win32.Rakhni, Trojan-Ransom.Win32.Agent.iih, Trojan-Ransom.Win32.Aura, Trojan-Ransom.Win32.Autoit, Trojan-Ransom.AndroidOS.Pletor, Trojan-Ransom.Win32.Rotor, Trojan-Ransom.Win32.Lamer, Trojan-Ransom.MSIL.Lortok, Trojan-Ransom.Win32.Cryptokluchen, Trojan-Ransom.Win32.Democry, Trojan-Ransom.Win32.Bitman version 3 and 4, Trojan-Ransom.Win32.Libra, Trojan-Ransom.MSIL.Lobzik, Trojan-Ransom.Win32.Chimera, Trojan-Ransom.Win32.Mircop, and Trojan-Ransom.Win32.Crusis

Of these families, RakhniDecryptor can decrypt files that have their filenames encrypted and renamed to the one of the following formats:
