Ransomware

In what could only be a joke, a new ransomware has been discovered called "PUBG Ransomware" that will decrypt your files if you play the game called PlayerUnknown's Battlegrounds. Discovered by MalwareHunterTeam, when the PUBG Ransomware is launched it will encrypt a user's files and folders on the user's desktop and append the .PUBG extension to them. When it has finished encrypting the files, it will display a screen giving you two methods that you can use to decrypt the encrypted files.

Underground ransomware is deployed by the Russia-based RomCom group (Storm-0978) and has victimized companies across multiple industries since July 2023 by exploiting CVE-2023-36884, encrypting files without changing extensions and deleting Volume Shadow Copies and Windows event logs in double-extortion campaigns.
