What is Lilocked ransomware? And how does it implement its attack?
Lilocked ransomware, also known as Lilu, is a dangerous ransomware threat that can corrupt important data in an infected computer. Based on the reports, this new crypto-malware circulates the web via outdated WordPress sites. Its encrypted files can be identified by the “.lilocked” extension and it uses the AES encryption algorithm in locking them.
The instant it implement its attack, Lilocked ransomware runs a malicious payload file in the system which will establish a connection to a remote server controlled by the attackers. After that, it may download a couple of malicious components from this remote server and place them to system folders. Lilocked ransomware then employs a data gathering module used to obtain information about the user and the system. The data gathered, along with the malicious components are used for the stealth protection module which protects Lilocked ransomware from any security or antivirus programs that could interrupt its attack. It also modifies some registry entries and keys so that it can automatically run on every system boot. After that, it starts to encrypt its targeted files using both AES ciphers. Following data encryption, it appends .Lilocked extension to every affected file and releases a file named “#README.lilocked.txt” or “#README.txt” which contains the following message:
“WE APOLOGIZE BUT YOU NEED TO PAY THE RANSOM – ALL YOUR FILES HAS BEEN LILOCKED
IT IS STRONG ENCRYPTION AND YOU LOSS YOUR DATA UNLESS YOU PAY US
