KJH – General Info
The KJH mean a ransomware-type infection. The virus comes from the Dharma ransomware family. KJH was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. KJH adds the “.kjh” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by KJH, will be renamed into “myphoto.jpg.kjh“. As quickly as the encryption is finished, KJH places a special text file into every folder containing the encrypted data.The message given by KJH text file asking for the ransom is absolutely the like the statements given by other ransomware representatives belonging to the Dharma type. It literally discusses that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Sadly, this is definitely true. The kind of cryptography mechanism used by KJH is still not correctly examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.
Another technique of KJH is that the victims cannot access to the key. The key is saved on a particular server run by the frauds related to KJH ransomware. To get the key and recover the important information people have to pay the ransom.
KJH encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

Nonetheless, irrespective of the requested amount, people must stay away from paying the virus. Cyber frauds are not fair, so they tend to entirely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive outcome and people just waste 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 KJH ransomware and to recover the information data totally free. Thus, the only right decision is to recover the lost information from the available backup.
