Jenkins Virus Ransomware

The Jenkins stands for a ransomware-type infection. Jenkins was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. Jenkins adds the “.jenkins” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Jenkins, will be renamed into “myphoto.jpg.jenkins“. As soon as the encryption is finished, Jenkins places a special text file into every folder containing the encrypted data.

The message given by Jenkins text file asking for the ransom is absolutely the like the statements given by other ransomware representatives. It actually points out that the info is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by Jenkins is still not correctly examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is completely distinct. It is impossible to bring back the files without the key available.

Another technique of Jenkins is that the victims cannot gain access to the key. The key is stored on a particular server run by the frauds related to Jenkins ransomware. To get the key and recover the important information people need to pay the ransom.
