Gunra – Ransomware
The Gunra mean a ransomware-type infection. Gunra was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. Gunra adds the “.ENCRT” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Gunra, will be renamed into “myphoto.jpg.ENCRT“. As quickly as the encryption is finished, Gunra places a special text file into every folder containing the encrypted data.The message given by Gunra text file asking for the ransom is definitely the same as the statements given by other ransomware representatives. It literally discusses that the information is encrypted and that the only way to bring back it is to use a a distinct decryption key. Sadly, this is absolutely true. The kind of cryptography mechanism applied by Gunra is still not properly examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is completely unique. It is impossible to bring back the files without the key available.
Another trick of Gunra is that the victims cannot gain access to the key. The key is stored on a specific server run by the frauds connected with Gunra ransomware. To get the key and recover the important info people need to pay the ransom.
Gunra encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.
