Remove Acuna Virus (.[Cusapool@firemail.cc].Acuna Files Ransomware) – Phobos Ransomware

Acuna Virus – Details

The Acuna stands for a ransomware-type infection. The infection comes from the Phobos ransomware family. Acuna was elaborated particularly to encrypt all major file types. Once the file is encrypted people are not able to use them. Acuna adds the “.[Cusapool@firemail.cc].Acuna” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Acuna, will be renamed into “myphoto.jpg.[Cusapool@firemail.cc].Acuna“. As quickly as the encryption is completed, Acuna places a special text file into every folder containing the encrypted data.

The message given by Acuna text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the Phobos type. It literally 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 definitely true. The kind of cryptography mechanism used by Acuna is still not correctly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is absolutely distinct. It is impossible to restore the files without the key available.

Another technique of Acuna is that the victims cannot access to the key. The key is stored on a particular server run by the frauds connected with Acuna ransomware. To get the key and recover the important info people need to pay the ransom.

Nevertheless, irrespective of the asked for quantity, people should stay away from paying the ransom. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive outcome and people simply waste their money for absolutely nothing.

We highly advise that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Acuna ransomware and to recover the information data free of charge. Hence, the only best decision is to recover the lost information from the available backup.
