Remove C4H Virus (+Decrypt .C4H files) – GlobeImposter Ransomware

C4H – Ransomware

The C4H mean a ransomware-type infection. The virus comes from the GlobeImposter ransomware family. C4H was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are unable to use them. C4H adds the “.C4H” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by C4H, will be renamed into “myphoto.jpg.C4H“. As soon as the encryption is finished, C4H places a special text file into every folder containing the encrypted data.

The message given by C4H text file asking for the ransom is definitely the like the statements given by other ransomware virus representatives coming from the GlobeImposter type. It actually mentions that the information is encrypted which the only way to restore it is to use a a special decryption key. Regretfully, this is absolutely true. The type of cryptography mechanism applied by C4H is still not appropriately examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is completely distinct. It is difficult to restore the files without the key available.

Another technique of C4H is that the victims cannot access to the key. The key is saved on a particular server run by the frauds associated with C4H ransomware. To get the key and recover the important info people have to pay the ransom.

Nevertheless, irrespective of the asked for amount, people must keep away from paying the ransom. Cyber frauds are not fair, so they tend to completely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom usually does not give any positive result and people simply lose their money for absolutely nothing.

We strongly recommend that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack C4H ransomware and to recover the data data for free. Thus, the just best decision is to recover the lost information from the available backup.
