Arai Ransomware Goes for Double Extortion

Arai is the name of a newly discovered strain of file-encrypting malware. The new variant does not seem to belong to any particular ransomware family.

The ransomware works largely as you would expect it to - it encrypts almost all files on the victim system and leaves them unusable. Encrypted files receive the ".araicrypt" extension, appended after their old one. This means that a file named "music.mp3" will turn into "music.mp3.araicrypt" once it has been encrypted.

The Arai ransomware will scramble most document, media, archive and database file types, making it a significant data security threat.

The ransom note is deposited in a plain text file named "READ_TO_RESTORE_YOUR_FILES.txt". The note threatens a leak of potentially sensitive data stolen in the attack, in what has become a standard method for double extortion among ransomware operators.

The full text of the note is as follows:
