What is a FONIX file?

A FONIX file is a file that has been encrypted by Fonix ransomware, which is malware distributed by cybercriminals. It contains a file, such as a .PDF, .JPG, or .DOCX file, that the virus has renamed and encrypted. FONIX files can be decrypted and restored to their original state using Kaspersky RakhniDecryptor.

More Information

In June 2020, some PC users began reporting that their computers had been infected by a new form of ransomware called Fonix. The ransomware encrypts a variety of users' files using four methods of encryption, renames the files to use the .fonix or .xinof extensions, and produces a ransom message named # How to Decrypt Files #.hta. Between June 2020 and January 2021, Fonix infected over 5,000 PCs.

In January 2021, the criminals behind Fonix decided to stop producing the ransomware and to provide decryption companies with the keys needed to decrypt FONIX files. As a result, numerous groups have produced free Fonix decryptors that can be used to restore users' files.

How to open a FONIX file

FONIX files can be decrypted for free using Kaspersky RakhniDecryptor (Windows). Detailed instructions for how to use RakniDecryptor can be found on Kaspersky's website, which is linked below.


FileInfo.com recommends you never pay a ransom to decrypt files encrypted by ransomware. Paying a ransom encourages ransomware distributors to continue their efforts, and there is no guarantee that paying a ransom will give you access to your files. Instead, you should restore your data from a recent backup created before the ransomware infected your computer.
