CR1 – General Info
The CR1 stands for a ransomware-type infection. The virus comes from the PureLocker ransomware family. CR1 was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. CR1 adds the “.CR1” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by CR1, will be renamed into “myphoto.jpg.CR1“. As soon as the encryption is finished, CR1 places a special text file into every folder containing the encrypted data.The message given by CR1 text file asking for the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the PureLocker family. It literally points out that the info is encrypted which the only way to restore it is to use a a special decryption key. Sadly, this is definitely true. The sort of cryptography mechanism used by CR1 is still not correctly examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is absolutely unique. It is difficult to restore the files without the key available.
Another trick of CR1 is that the victims cannot access to the key. The key is kept on a particular server run by the frauds connected with CR1 ransomware. To get the key and recover the important information people need to pay the ransom.
CR1 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.
