Dotmap Virus Ransomware

The Dotmap mean a ransomware-type infection. The virus comes from the Djvu ransomware family. Dotmap was elaborated specifically to encrypt all major file types. As soon as the encryption is completed, Dotmap places a special text file into every folder containing the encrypted data.

The message given by Dotmap text file asking for the ransom is definitely the like the statements given by other ransomware representatives belonging to the Djvu type. It actually discusses that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Sadly, this is absolutely true. The type of cryptography mechanism used by Dotmap is still not correctly examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.

Another technique of Dotmap is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds associated with Dotmap ransomware. To get the key and recover the important info people need to pay the ransom, which amounts to $980. To acquire the payment information users are instructed to contact the frauds through e-mail or telegram. The alert also shows that the users need to contact the Dotmap developers within 72 hours after the encryption occurred. The message says that doing so users will get a 50% discount, so the ransom quantity will drop down to $490.

However, regardless of the requested amount, people should keep away from paying the ransom virus. Cyber frauds are not fair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive outcome and people just waste their money for nothing.

We highly recommend that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Dotmap ransomware and to recover the data data totally free. Thus, the only right decision is to recover the lost information from the available backup.
