What is a KIFR file?

A file with the .kifr extension has been encrypted and renamed by KIFR ransomware. It contains a document, image, video, or other type of file the ransomware is holding hostage. These files have the .kifr extension added to their original extension, producing a compound extension such as .docx.kifr.

More Information

KIFR ransomware first appeared in April 2023. It is one of many variants of .STOP ransomware, which various cybercriminals use to attack users' computers and maliciously encrypt their files.

After encrypting a user's files, KIFR ransomware produces a plain text ransom note named _readme.txt in every folder that contains an infected file. In theory, this ransom note contains instructions users can follow to pay a ransom and decrypt their files. However, ransomware distributors are not trustworthy, and therefore you should not pay a ransom to decrypt your files.

How did my computer get infected by KIFR ransomware?

KIFR ransomware is most commonly distributed within programs that appear to be legitimate but are actually adware and malware bundles. If you recently downloaded and installed an unverified program, that may be how your computer became infected by KIFR ransomware.

How to open a KIFR file

Because KIFR files are encrypted, you cannot open them. At this time, there is no way to decrypt KIFR files. The best way to restore files encrypted by KIFR ransomware is to retrieve them from a recent backup or perform a System Restore.


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.
