What is Scarab Leen ransomware? And how does it carry out its attack?

Scarab Leen ransomware is a data-encrypting malware which also happens to be an addition to the ever growing family of Scarab ransomware. This is one of the new variants released by the infamous ransomware group and this time it uses the .leen extension in marking its encrypted files. It still uses the same tactics and encryption algorithm in carrying out its attack.

Once the Scarab Leen ransomware attack takes place, a series of malicious activities will be implemented in the targeted computer. It starts by placing its malicious payload into a system folder which is the one to employ an information gathering module. During this process, the malware collects information about the infected system and user and send the gathered data to a remote server. From there, a couple of malicious files will then be added into the computer which helps in keeping the crypto-virus from getting detected by any program in the computer like antivirus programs. Some of these malicious files are also responsible for modifying the Windows Registry that keeps the malware running on every system boot. Following these changes, Scarab Leen ransomware will look for files to encrypt and locks them using a strong encryption algorithm and adds the .leen extension to the encrypted files. Moreover, it will drop a file named “INSTRUCTIONS FOR RESTORING FILES.txt” which contains the following message:
