Fsociety ransomware-affected file
File type: Ransomware encrypted file
A file with the [email protected] file extension has been encrypted by Fsociety ransomware.
The ransomware changes the original file's suffix after encrypting its contents, so the affected file cannot normally be opened in its original application.
File type category:
Ransomware encrypted file
Date updated: October 5, 2026
Fsociety ransomware encrypts users' files and appends the [email protected] suffix to their names. The suffix identifies files affected by this ransomware and does not represent a usable file format.
The ransomware also creates a fs0ciety.html file containing its ransom note. The note includes an ID associated with the infection, which may be needed when seeking assistance or investigating possible recovery options.
A file with this suffix cannot normally be opened by the program that created the original file. Do not rename the file or remove the suffix, because doing so does not decrypt its contents.
Open fs0ciety.html in a web browser to read the ransom note. For assistance, consult a reputable ransomware-help resource such as BleepingComputer's ransomware help forum and keep the ID from the note available.
This file cannot be converted in the usual sense. Its contents must first be recovered or decrypted; after recovery, the resulting original file can be opened or exported using a suitable application.
