Remove Arena Virus (Macgregor@aolonline.top) – Dharma Ransomware

Arena Virus – Details

The Arena mean a ransomware-type infection. The virus comes from the Dharma ransomware family. Arena was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are not able to use them. Arena adds the “.[Macgregor@aolonline.top].arena” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Arena, will be renamed into “myphoto.jpg.[Macgregor@aolonline.top].arena“. As quickly as the encryption is completed, Arena places a special text file into every folder containing the encrypted data.

The message given by Arena text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the Dharma family. It literally points out that the info is encrypted and that the only way to bring back it is to use a a special decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism used by Arena is still not appropriately examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.

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

Nonetheless, regardless of the asked for quantity, people need to stay away from paying the ransom virus. Cyber frauds are not fair, so they tend to entirely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive outcome and people just waste their money for absolutely nothing.

We strongly encourage 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 Arena ransomware and to recover the data data free of charge. Therefore, the just right decision is to recover the lost data from the available backup.
