Hunter Ransomware is a newly discovered variant of the Prince Ransomware family. This malicious software encrypts victims’ files, appending the “.Hunter” extension, and demands a ransom in cryptocurrency for file recovery. It also drops a ransom note named “Decryption Instructions.txt” and modifies the desktop wallpaper to warn victims about the attack.

How Hunter Ransomware Works
Once Hunter infiltrates a system, it begins encrypting files and renaming them with the “.Hunter” extension. For example:
- 1.jpg → 1.jpg.Hunter
- 2.png → 2.png.Hunter
- 3.exe → 3.exe.Hunter
After encryption, it drops a ransom note titled “Decryption Instructions.txt”, demanding payment in cryptocurrency. The attackers warn victims against renaming or modifying the encrypted files, claiming this may lead to permanent data loss.
