Kupidon – Ransomware

The Kupidon mean a ransomware-type infection. The virus comes from the Kupidon ransomware family. Kupidon was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Kupidon adds the “.kupidon” extension for each file encrypted by it.

The message given by Kupidon text file asking for the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Kupidon type. It actually points out that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism used by Kupidon is still not properly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.

Another trick of Kupidon is that the victims cannot access to the key. The key is stored on a specific server run by the frauds associated with Kupidon ransomware. To get the key and recover the important info people need to pay the ransom.
