How to remove Locknet Ransomware and decrypt .locknet files

What is Locknet Ransomware

Locknet Ransomware is a type of malicious software that belongs to the MedusaLocker family. Its primary purpose is to encrypt files on a victim’s computer, making them inaccessible. The ransomware also renames files by adding the .locknet extension to filenames. For instance, it changes a file named 1.jpg to 1.jpg.locknet, 2.png to 2.png.locknet, and so forth. Locknet Ransomware uses a combination of RSA and AES encryption algorithms to encrypt the files on the infected computer. These encryption methods are robust and secure, making it extremely difficult to decrypt the files without the specific decryption key. After encrypting the files, Locknet Ransomware creates a ransom note named HOW_TO_BACK_FILES.html. This note informs victims that their network has been breached and all important files have been encrypted. It warns against attempting to restore the files with third-party software, as this could permanently damage them. The attackers claim that only they can provide the decryption solution.

As of the current date, there are no free decryption tools available for Locknet Ransomware. The attackers claim that they are the only ones who can provide a decryption solution, and they typically demand a ransom in exchange for this. Given the robustness of the encryption used by Locknet Ransomware, decrypting .locknet files without the specific decryption key is extremely challenging. As mentioned earlier, no free decryption tools are currently available. Therefore, the best course of action is to prevent the infection in the first place by following the best cybersecurity practices. These include regularly updating software, avoiding suspicious emails and downloads, and maintaining regular backups of important files.

In case of an infection, it’s recommended to remove the ransomware from the system using a reliable anti-malware tool. After removal, if you have a recent backup of your files, you can restore them. If not, you may need to consider professional data recovery services. However, it’s essential to note that paying the ransom is not recommended, as it does not guarantee that the attackers will provide a working decryption key, and it encourages them to continue their malicious activities.

How Locknet Ransomware infected your computer

Locknet Ransomware can infect computers through various methods. One common method is through phishing emails, where the ransomware is hidden in an attachment or a link. When the recipient opens the attachment or clicks the link, the ransomware is downloaded and executed on their system. Another method is through malicious advertisements or third-party downloaders. Engaging with these deceptive ads or using these downloaders can result in the ransomware being installed on the user’s computer. Additionally, obtaining or utilizing counterfeit or illicit software can also lead to a Locknet Ransomware infection.
