Remove Mamona Ransomware (HAes)

Mamona is a highly destructive ransomware-type program that encrypts files on the victim’s system and demands payment in exchange for a decryption tool. This ransomware appends the “.HAes” extension to all encrypted files, rendering them inaccessible. After the encryption process is completed, Mamona changes the desktop wallpaper and drops a ransom note titled “README.HAes.txt” in affected folders.

This ransomware follows the double extortion tactic, meaning that in addition to encrypting files, it also steals sensitive data and threatens to leak it publicly if the victim refuses to pay. Victims are warned against seeking external help, modifying encrypted files, or involving law enforcement. Like most ransomware threats, Mamona spreads through malicious email attachments, deceptive downloads, and exploit kits.
