Emsisoft releases a free decrypter for the GetCrypt Ransomware

[harlan4096]

Our malware team just released a decrypter for the GetCrypt ransomware.

GetCrypt is a ransomware spread by the RIG exploit kit and encrypts files using Salsa20 and RSA-4096. It appends a random 4-character extension to files that is unique to the victim such as four random uppercase letters (e.g. .NHCR) generated from the victim’s CPU’s serial number. A test version used a static “.EZDZ” extension.

According to BleepingComputer‘s Lawrence Abrams, GetCrypt will utilize the WNewEnumResourceW function to enumerate a list of available network shares, or if it fails, will try to brute force network account credentials instead.

Malware researcher @nao_sec discovered the ransomware and ethical hacker @VK_Intel shared his analysis of the exploit to BleepingComputer.

If you’re a victim of this ransomware, DO NOT PAY the ransom. Download the decrypter and reach out to us if you have any questions.
