What is Lbkut ransomware? And how does it implement its attack?
Lbkut ransomware is a data-encrypting virus and a new variant of the infamous Scarab ransomware that uses a “.lbkut” extension, hence the name. Its ransom note is written in Russian which indicates that it mostly targets Russian-speaking users. Other than the extension and ransom note, there are no other noticeable changes in this new Scarab variant. It still uses the same sequence when implementing its attack.
The instant Lbkut ransomware infects a targeted computer, it will establish a connection to a remote server where it downloads several malicious files as well as send data about the infected machine. The malicious files are placed into system folders to repress ad create system processes that allow Lbkut ransomware to remain undetected. Aside from that, it also modifies the Windows Registry in order to run on every system boot. After these changes are applied, it will begin its search for targeted files which are usually user-generated ones like music, videos, pictures, documents, and many more. It uses a strong encryption algorithm in locking files. After the encryption, it adds the .lbkut suffix on every encrypted file and opens a ransom note that contains the following text:
