Remove Null Virus (.[nullcipher@cock.li].null Files Ransomware) – Dharma Ransomware

Null Virus – Details

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

The message given by Null text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the Dharma family. It literally points out that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism used by Null is still not appropriately examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is totally distinct. It is difficult to bring back the files without the key available.

Another trick of Null is that the victims cannot access to the key. The key is kept on a specific server run by the frauds connected with Null ransomware. To get the key and recover the important information people need to pay the ransom.

Nonetheless, irrespective of the requested amount, people should keep away from paying the ransom virus. Cyber frauds are unfair, so they tend to totally ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people simply waste their money for nothing.

We strongly recommend 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 Null ransomware and to recover the information data totally free. Hence, the just best decision is to recover the lost information from the available backup.
