What is MedusaLocker ransomware? And how does it carry out its attack?
MedusaLocker ransomware is a malicious program that can harm the important data in a computer, leaving them inaccessible to users. This nasty ransomware threat adds a “.encrypted” suffix to each file it encrypts. The instant its malicious payload reaches the targeted computer, it establishes a connection to its remote Command and Control server. It then begins to execute its attack by gathering information about the system. The information gathered is sent to the C&C server. From there, it downloads more malicious files that aid it in executing its attack. These malicious files are used to avoid detection from any AV program.
Additionally, MedusaLocker ransomware also alters the Windows Registry so it can achieve persistence. After that, it starts the encryption process by employing the AES cipher in locking its targeted files. Once the encryption is completed, you will notice that most of your files have the .encrypted extension. This means that files with this extension is encrypted and can’t be accessed. You will find more information about the attack once MedusaLocker ransomware releases the file named “HOW_TO_RECOVER_DATA.html” which contains the following content:
