Remove Artemis Virus (.[UltimateHelp@techmail.info].ultimate Files Ransomware) – Filecoder Ransomware

Artemis Virus – Details

The Artemis stands for a ransomware-type infection. The infection comes from the Filecoder ransomware family. Artemis was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Artemis adds the “.[UltimateHelp@techmail.info].ultimate” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Artemis, will be renamed into “myphoto.jpg.[UltimateHelp@techmail.info].ultimate“. As soon as the encryption is finished, Artemis places a special text file into every folder containing the encrypted data.

The message given by Artemis text file asking for the ransom is definitely the same as the statements given by other ransomware representatives belonging to the Filecoder type. It actually mentions that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Unfortunately, this is absolutely true. The sort of cryptography mechanism applied by Artemis is still not properly examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is totally unique. It is difficult to bring back the files without the key available.

Another trick of Artemis is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds connected with Artemis ransomware. To get the key and recover the important info people have to pay the ransom.

However, irrespective of the asked for amount, people must stay away from paying the ransom virus. Cyber frauds are not fair, so they tend to entirely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people just lose their money for absolutely nothing.

We strongly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Artemis ransomware and to recover the information data for free. Therefore, the just best decision is to recover the lost data from the available backup.
