File Ransomware Goes for a Generic Name

ransomware

File ransomware is the rather generic-sounding name of a newly discovered strain of ransomware. Despite its bland name, the new variant belongs to the Phobos family of ransomware clones - one of the most infamous malware groups.

Upon deployment, the File ransomware will encrypt files on the victim system, leaving system files intact so the OS can keep functioning and encrypting nearly everything else. Affected files include documents, media, archive and database extensions. Once encrypted, files receive a multi-part new extension that includes the victim's ID, the contact email used by File's operator and the ".FILE" string.

This will make a file previously called "document.doc" turn into "document.doc[victim ID].[teamchic@yandex.com].FILE".

The ransom note is dropped inside two separate files, one plain text and one in .hta format, named "info.txt" and "info.hta" respectively. The full text of the ransom note goes as follows:
