Davda – Ransomware

The Davda mean a ransomware-type infection. The infection comes from the Djvu ransomware family. Davda was elaborated specifically to encrypt all major file types. When the file is encrypted people are not able to use them. Davda adds the “.davda” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Davda, will be renamed into “myphoto.jpg.davda“. As quickly as the encryption is completed, Davda places a special text file into every folder containing the encrypted data.

The message given by Davda text file asking for the ransom is absolutely the like the statements given by other ransomware representatives belonging to the Djvu clan. It actually points out that the information is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism used by Davda is still not properly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is totally distinct. It is impossible to restore the files without the key available.

Another trick of Davda is that the victims cannot gain access to the key. The key is stored on a specific server run by the frauds related to Davda ransomware. To get the key and recover the important information people need to pay the ransom, which totals up to $980.
