ZOH Virus Removal Guide (+Decode .zoh files) – Dharma Ransomware

ZOH Virus – Details

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

The message given by ZOH text file requesting the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the Dharma type. It literally points out that the info is encrypted and that the only way to restore it is to use a a special decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism used by ZOH is still not correctly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is completely unique. It is difficult to bring back the files without the key available.

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

However, irrespective of the requested amount, people must stay away from paying the virus. Cyber frauds are unfair, so they tend to totally disregard 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 waste their money for absolutely nothing.

We highly advise 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 ZOH ransomware and to recover the information data totally free. Thus, the only best decision is to recover the lost data from the available backup.
