Demon Ransomware Uses Terse Ransom Note

ransomware

Demon ransomware is the name of a newly discovered ransomware variant. While there is no hard evidence that it belongs to any bigger ransomware family, some antivirus products are detecting it as a variant of the Babuk family, which means it may be using chunks of Babuk code.

Demon works predictably, encrypting the victim system and leaving most files on it in an unopenable state. Once the ransomware encrypts a file, it appends the ".demon" extension to it. This process will turn a file named "document.doc" into "document.doc.demon" once it has been fully encrypted.

The encryption process will affect most file types and extensions, including document, media, archive and database files.

The ransomware deposits its ransom note inside a plain text file with the name "How To Recover Your Files.txt". The full contents of the ransom note are as follows:
