MessedUp – Ransomware

The MessedUp stands for a ransomware-type infection. The infection comes from the Phobos ransomware family. MessedUp was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. MessedUp adds the “.[ICQ@FIREYOURITGUY].messedup” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by MessedUp, will be renamed into “myphoto.jpg.[ICQ@FIREYOURITGUY].messedup“. As quickly as the encryption is finished, MessedUp places a special text file into every folder containing the encrypted data.

The message given by MessedUp text file asking for the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Phobos family. It actually discusses that the information is encrypted which the only way to restore it is to use a an unique decryption key. Regretfully, this is absolutely true. The sort of cryptography mechanism applied by MessedUp is still not correctly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is completely distinct. It is difficult to bring back the files without the key available.

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

However, regardless of the asked for quantity, people must keep away from paying the virus. Cyber frauds are not fair, 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 usually does not provide any positive outcome and people just lose their money for nothing.

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