Marnet is a ransomware threat that encrypts and renames files, adding the extension '.marnet2' to the original filenames. The Marnet Ransomware also drops a ransom note in the form of an HTML file called 'how_to_back_files.html.' Once infected, users may find their files renamed with that extension, such as '1.jpg.marnet2,' '2.png.marnet2,' and so on, with the number in the extension potentially changing from case to case. The Marnet Ransomware belongs to a family of ransomware known as MedusaLocker.

Marnet Ransomware’s Demands
Victims of this ransomware are warned that attempting to restore their files using third-party software will permanently damage them, and their files cannot be decrypted without the interference of the attackers. The ransom note also states that personal data has been gathered and will be disclosed to the public or sold to competitors/third parties if victims refuse to pay the ransom. To contact the threat actors, victims are provided with a Tor website and two email addresses ('firstname.lastname@example.org' and 'email@example.com'). Furthermore, failure to contact the cybercriminals within 72 hours will result in an increased price for decryption.
How is a Ransomware Attack Executed?
One of the common infection strategies used by attackers is to send out lure emails containing corrupted links or attachments disguised as being from trusted sources, such as banks, e-commerce sites or other known companies. If the users fall for it, they will click on the link and be directed to a Web page hosting malware that is used to infect their systems with ransomware.
Cyberattackers also often exploit weaknesses in unpatched software and operating systems so they can gain access to the targeted devices without users knowing it. Once they gain access, they can install ransomware that will encrypt the data on the system.
