Kraken Cryptor Ransomware

First observed in August 2018, Kraken Cryptor is a ransomware tool that is delivered to users disguised as a legitimate anti-virus application called SuperAntiSpyware.

The file name for the legitimate SuperAntiSpyware Free installer is called SUPERAntiSpyware.exe. The Kraken Cryptor installer spotted by VirusTotal was called SUPERAntiSpywares.exe. The only difference between the two names is the addition of a s to the malicious executable. This malicious executable is no longer available from superantispyware.com.

Kraken Cryptor was initially distributed as a malicious executable file hosted on the SuperAntiSpyware website, an anti-virus and malware program. Both the real and malicious versions were available for download until late August 2018, presumably when the owners of the site were notified, at which point they removed the malicious file. However, numerous other download portal sites continue to host the malicious version.

Once installed, Kraken Cryptor will check the system language of the infected device before deployment. If the languages of any 17, mainly former USSR, countries are detected it will not proceed any further. It will then attempt to close a number of processes and delete or disable Windows recovery services before encrypting all available files with extensions that match a hard-coded list. Kraken Cryptor will also use the SDelete tool to overwrite all free space on the affected drives, possibly to hinder file recovery.

Unfortunately, at this time there is no way to decrypt files encrypted by the Kraken Cryptor Ransomware variant for free.

When encrypting a computer, it will scan the computer for files with the following extensions.
