Ziggy announces retirement 

In early February 2021, the Ziggy group announced via Telegram that they would be shutting down their ransomware operation and releasing victims’ decryption keys.  

The group’s early retirement was apparently motivated by guilt and fear of legal repercussion. Speaking with BleepingComputer, an administrator for the Ziggy group said that they felt guilty about their actions and expressed concerns over global law enforcement efforts, which recently saw charges brought against Emotet and Netwalker affiliates. 

Following the announcement, the Ziggy ransomware admin released an SQL file containing 922 decryption keys, 340 of which are unique IDs. We can confirm that the keys are legitimate.

The admin also released a decryptor that victims of Ziggy can use with the decryption keys listed in the SQL file. However, the decryptor is cumbersome to use and crashes frequently. We strongly recommend that victims use our decryptor instead of the attacker-provided decryptor. 

The Emsisoft decryptor is simple to use and requires just one encrypted file and an Internet connection. The decryptor then pulls decryption keys from our server based on the victim’s ID, and also the offline keys. Victim IDs are based on the volume serial of the C: drive of the infected machine.
