What is Gamma Ransomware?
Gamma is yet another crypto-malware from Crysis family which has fallen into disrepute for creating dangerous Dharma ransomware and many others. Like previous ones, Gamma Ransomware encodes personal files and then leaves a note demanding money. The ransom amount is not public (cybercriminals usually demand $500-$1000 in Bitcoins), it is established individually after the user sends them assigned ID number. Even though you have the funds available to decrypt your files, we still advise you not to do it. The point is, a lot of people fall into the trap of this type of scam. There are a lot of cases where cybercriminals do not help their victims, even if they pay up. Remember, you are up against fraudsters so nobody will give any guarantees that they will fulfill their commitments. Hence, there is a high risk of being left without decryptor and money. Instead, you may try using this guide to remove Gamma Ransomware and decrypt .gamma files without spending any money.
The principle of work of the ransomware is always the same – to encrypt files and then to require payment. Gamma Ransomware encodes users’ personal files using AES encryption algorithm. As a result, each infected file will be renamed and appended with “.gamma” extension. For example, file “myfamily.jpg” will turn into “myfamily.jpg.id-1W453R12.[firstname.lastname@example.org].gamma”. Once all the data is encrypted, the ransomware displays pop-up window and creates FILES ENCRYPTED.txt file, where the user may find the demands of criminals:
Here’s text from Gamma Ransomware pop-up:
