What is Wesker ransomware? And how does it implement its attack?

Wesker ransomware is a dangerous file-encrypting virus that can do serious damage to your computer’s files. It is designed to lock these files to make them inaccessible and demand ransom from its victims. It uses the “WESKER_ENC” file marker in marking the files it encrypts.

Wesker Ransomware

Once it infects a computer, it drops a malicious payload used to establish a connection between the infected computer and a remote server controlled by the attackers. From this remote server, several malicious components are then downloaded and placed in the system folders. They are used to help Wesker ransomware in executing its attack. It also modifies some entries and sub-keys in the Windows Registry which allows it to run on every system boot.

After it modifies system settings, it starts to encrypt various files in the system, especially the common user-generated ones like images, documents, videos, databases, audio files, and many more. It uses the AES encryption algorithm in encrypting them and after the encryption, it adds the “WESKER_ENC” suffix to every affected file and opens a file named “!!! INSTRUCTION_RNSMW !!!.txt” that states:

“the Hello, dear friend E

It isn’t practical paying the ransom which is why it isn’t advised that you do so. The best thing you can do when infected with this ransomware Trojan is to remove it carefully from your system first and then try out free recovery options, be it through a free decryption software or using the Windows Previous Versions feature.
