How to Remove ‘Gamma’ Ransomware – Security Tips


Gamma is a dangerous piece of malicious software, classified as ransomware. Discovered by a malware researcher named Jakub Kroustek, Gamma ransomware is designed to stealthily infiltrate the targeted system and hold the victim’s personal files stored on it hostage (convert files into an inaccessible format using encryption) until a ransom payment (in the form of cryptocurrencies) is made. 

It belongs to the family of ransomware viruses called Crysis. Like other ransomware viruses of this family, it doesn’t provide any information regarding the cryptographic algorithm (symmetric or asymmetric) used to encrypt data, though, successful decryption requires a special key/ tool created individually for each affected user.

Once the encryption procedure is done, the Gamma ransomware creates its ransom note within the “FILES ENCRYPTED.txt” file, which can be found on each folder containing encrypted files. Like RedDot, MMTA, Venus, and several other ransomware-type viruses, it uses the ransom note to inform victims’ all data has been locked and now they require to contact the ransomware authors via provided email address to initiate the data recovery process.
