ACUTE Virus Removal Guide (+Decode .acute files) – Phobos Ransomware

ACUTE Virus – Details

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

The message given by ACUTE text file requesting the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the Phobos family. It actually discusses that the information is encrypted and that the only way to bring back it is to use a an unique decryption key. Regretfully, this is absolutely true. The kind of cryptography mechanism used by ACUTE is still not appropriately examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is totally distinct. It is difficult to bring back the files without the key available.

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

However, irrespective of the requested quantity, people should keep away from paying the virus. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people just waste their money for nothing.

We strongly recommend 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 ACUTE ransomware and to recover the information data for free. Thus, the only right decision is to recover the lost data from the available backup.
