What is Li ransomware? And how does it execute its attack?

Li ransomware is a new crypto-malware designed to lock important data in a computer. It also happens to be a new addition to the Scarab ransomware group. This new Scarab variant adds a “.li” extension to every file it encrypts. Like other Scarab variants, this one only has minimal changes like the extension it uses, ransom note, and the email address but when it comes to the execution of its attack, it’s pretty much the same as other variants of Scarab ransomware.

Once it is loaded in the computer, Li ransomware initiates a sequence of malicious activities that affects important system settings and processes. It starts by establishing a connection to a Command and Control server managed by the attackers. After it establishes the connection, it downloads its other malicious components which will be used on its attack. It then employs an information gathering module as well a stealth protection module used to collect information from the computer and prevent any AV programs installed in the system from detecting the ransomware. Moreover, it also modifies some registry keys and sub-keys in the Windows Registry like the Run and RunOnce key to make sure that it can automatically run on every system startup. Following all these system changes, Li ransomware encrypts its targeted files and appends the .li extension. It then drops a file named “DECRYPT YOUR FILES.txt” which contains the following context:

“Hello.
Many vulnerabilities detected on your server.
Because of this, all your files have been encrypted with the strongest encryption.
All attempts to decrypt files on their own will lead to data corruption.

How does Li ransomware spread over the web?

It could also spread via malicious spam email campaigns – a common method used by ransomware developers to spread ransomware threats.
