CIZER Virus Removal Guide (+Decode .Cizer files) – Djvu Ransomware

CIZER – General Info

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

The message given by CIZER text file requesting the ransom is absolutely the like the statements given by other ransomware virus representatives coming from the Djvu family. It actually discusses that the information is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism applied by CIZER is still not correctly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is totally distinct. It is impossible to bring back the files without the key available.

Another trick of CIZER is that the victims cannot access to the key. The key is stored on a specific server run by the frauds related to CIZER ransomware. To get the key and recover the important information people have to pay the ransom, which amounts to $980. To obtain the payment details users are advised to contact the frauds through email or telegram. The alert also suggests that the users need to contact the CIZER developers within 72 hours after the encryption happened. The message says that doing so users will get a 50% discount, so the ransom amount will drop down to $490.

Nevertheless, irrespective of the asked for amount, people need to stay away from paying the ransom virus. 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 outcome and people just lose their money for absolutely nothing.

We highly 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 CIZER ransomware and to recover the information data free of charge. Thus, the just right decision is to recover the lost information from the available backup.
