Jigsaw ransomware-affected file
File type: Ransomware encrypted file
Files with the .paymrss file extension are encrypted files affected by Jigsaw ransomware.
The extension is appended to files that Jigsaw has encrypted and does not identify a normal, independently usable file format.
File type category:
Ransomware encrypted file
Date updated: October 5, 2026
Jigsaw ransomware encrypts users' files and appends the .paymrss file extension. The affected files contain the encrypted contents of the original files, so their original applications cannot normally open them.
Jigsaw demands a ransom paid in bitcoins in exchange for restoring access to the encrypted files. The extension is therefore associated with a ransomware-encrypted file rather than with a regular document, image, or archive format.
The Jigsaw Ransomware Decryptor by Michael Gillespie is available for Microsoft Windows and is intended to decrypt affected files.
A .paymrss file cannot normally be opened directly. On Microsoft Windows, use the Jigsaw Ransomware Decryptor to attempt to decrypt the affected files.
After successful decryption, open each restored file with the application that supports its original file type.
The .paymrss file is an encrypted ransomware-affected file, not a format that can be meaningfully converted. Decrypt it first with the Jigsaw Ransomware Decryptor.
After decryption, the restored file can be exported or converted using software that supports its original format.
