Usagoo – Ransomware

The Usagoo mean a ransomware-type infection. The virus comes from the Makop ransomware family. Usagoo was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Usagoo adds the “.[vassago0225@airmail.cc].usagoo” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Usagoo, will be renamed into “myphoto.jpg.[vassago0225@airmail.cc].usagoo“. As quickly as the encryption is completed, Usagoo places a special text file into every folder containing the encrypted data.

The message given by Usagoo text file asking for the ransom is absolutely the like the statements given by other ransomware virus representatives coming from the Makop clan. It actually mentions that the info is encrypted which the only way to restore it is to use a a special decryption key. Regretfully, this is definitely true. The type of cryptography mechanism applied by Usagoo is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is absolutely unique. It is impossible to bring back the files without the key available.

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

However, regardless of the asked for amount, people must keep away from paying the virus. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not provide any positive result and people simply lose their money for absolutely nothing.

We highly encourage 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 Usagoo ransomware and to recover the information data for free. Thus, the only right decision is to recover the lost data from the available backup.
