A newly discovered ransomware family is generating a different encryption key for each of the encrypted files but saves none of them, thus making data recovery impossible.

Dubbed Thanatos, the malware was discovered by MalwareHunterTeam and already analyzed by several other security researchers.

When encrypting files on a computer, the malware appends the .THANATOS extension to them. After completing the encryption, the malware connects to a specific URL to report back, thus allowing attackers to keep track of the number of infected victims.
