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

LIGMA ransomware is a dangerous file-encrypting malware that can cause irreversible damage to an infected computer. Based on the analysis of this crypto-malware, it does not contain any code snippet from any ransomware group. What’s interesting about it is the modules in this thread which shows that this ransomware is built around an engine that calls different functions.

Once it infects a computer, it follows a predesigned behavioral pattern. It launches a combination of information gathering module and stealth protection module which are both used to obtain data about the infected computer and user as well as protect the malware from any security programs installed in the system. It scans the computer for any security software that might interfere with the execution of the crypto-malware. This process is done via signature scans that look for antivirus engines as well as virtual machine hosts and debug environments. After it finds them, it terminates them and in some cases, delete the security software altogether. Aside from these capabilities, LIGMA ransomware can also manipulate files – it can delete and modify user files. It can also obtain administrative privileges in the system and sends the report to a remote server controlled by the attackers.

LIGMA ransomware is not a typical ransomware threat as it includes a dangerous Master Boot Record or MBR Wiper. This means that not only can it encrypt files but also delete the MBR files in the system. It scans the computer for the files with the following extensions:
