Gremit ransomware affected file
File type: Ransomware encrypted file
Files with the .rnsmwr file extension have been encrypted and renamed by Gremit ransomware.
File type category:
Ransomware encrypted file
Date updated: October 7, 2026
The .rnsmwr file extension is associated with Gremit Locker, a ransomware strain. It encrypts users' files and renames them, then demands a ransom, typically in Bitcoin (BTC).
This is not a normal file format used by an application. The extension identifies a file affected by the ransomware, and the original content cannot be accessed normally while it remains encrypted.
No regular application can open a .rnsmwr file as its original document, image, or other data. Removing the extension or renaming the file does not decrypt it.
As far as is known, no publicly available decryptor is known for .rnsmwr files. A compatible decryptor and the required key would be needed to recover the encrypted content.
A .rnsmwr file cannot be meaningfully converted while it is encrypted. Decryption must come first, and no known public decryptor is available for these files.
