CEZOR Virus Removal Guide (+Decode .cezor files) – DJVU Ransomware

CEZOR – Ransomware

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

The message given by CEZOR text file asking for the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the DJVU family. It actually mentions that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Regretfully, this is definitely true. The sort of cryptography mechanism applied by CEZOR is still not correctly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is absolutely distinct. It is impossible to restore the files without the key available.

Another trick of CEZOR is that the victims cannot access to the key. The key is kept on a particular server run by the frauds associated with CEZOR ransomware. To get the key and recover the important information people need to pay the ransom, which totals up to $980. To get the payment information users are instructed to contact the frauds through e-mail or telegram. The alert also indicates that the users require to contact the CEZOR developers within 72 hours after the files encryption happened. The message says that doing so users will get a 50% discount, so the ransom quantity will fall to $490.

However, regardless of the asked for amount, people must keep away from paying the ransom virus. Cyber frauds are unfair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive outcome and people just lose their money for absolutely nothing.

We strongly 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 CEZOR ransomware and to recover the information data totally free. Hence, the only right decision is to recover the lost data from the available backup.
