Threat Database Ransomware Ooss Ransomware

Ooss Ransomware

The Ooss Ransomware is a potent malware threat, designed to encrypt files and then extort its victims for money. The threat is a variant from the infamous STOP/Djvu Ransomware family, but that doesn't prevent it from being incredibly threatening. It can target a large number of file types and the strong encryption algorithm it uses ensures that the locked data will not be restored without having the specific decryption key.

The Ooss Ransomware follows the typical STOP/Djvu behavior. It appends the name of every encrypted file with a new file extension - '.ooss' in this case, and then drops a ransom note on the compromised machine in the form of a text file named '_readme.txt.'

Ooss Ransomware's Demands

Again, exactly as it should be expected from a STOP/Djvu variant, the Ooss Ransomware states that its operators demand to receive a ransom of exactly $980. However, if victims are to reach out and establish contact within the first 72 hours following the attack, the price will supposedly be decreased by 50% to $490.

The ransom note mentions two email addresses that can be used as communication channels - '' and '' It also clarifies that victims can send a single file to the hackers that will be unlocked for free and returned.
