What is Cezor ransomware? And how does it carry out its attack?
Cezor ransomware is a data-encoding malware designed to lock commonly user-generated files in an infected computer. It is yet another variant of the Djvu/STOP ransomware and uses a “.cezor” suffix in marking the files it encrypts. Like other variants of this infamous ransomware family, Cezor ransomware demands a ransom of either $980 or $490 and it still follows the same sequence in carrying its attack as its predecessors.
The instant it starts to implement its attack, Cezor ransomware will make a series of changes in the computer. These changes involve downloading other malicious files and placing them in several system folders. This is done in order to launch or repress system processes. Apart from controlling processes, Cezor ransomware also modifies the Windows Registry by messing with the values of registry keys and sub-keys. This allows the crypto-virus to execute its attack automatically each time the computer starts.
Following system modification, Cezor ransomware encrypts important files in the system using the AES encryption algorithm. After the encryption, it appends either the .cezor extension to every encrypted file and opens the _readme.txt file which contains the following message:
“ATTENTION!
Don’t worry my friend, you can return all your files!
All your files like photos, databases, documents, and other important are encrypted with the strongest encryption and unique key.
