When ransomware developers achieve huge media buzz like we saw with the PUBG Ransomware, it is not surprising to see other developers creating copycats. This is the case with two new in-development ransomware programs, if we can even call them that, for both Minecraft and Counter-Strike: Global Offensive (CS: GO).

Discovered by MalwareHunterTeam, neither of these programs actually encrypt any files on the computer. Instead they just display a Window that waits for a particular game related program to launch. Due to their limited functionality, I wouldn't even call them ransomware if it wasn't for the title that they used in the Window.

MC Ransomware

The first one is MC Ransomware, which we expect will force a user to play Minecraft in order to decrypt their files if encryption functionality is ever added. MalwareHunterTeam found 11 different samples of this infection, but when I checked them, the differences were minor between the first and latest one where they fixed a bug in the process detection routine.

Right now it just sits there waiting for someone to run an executable that is not MinecraftLauncher and that contains the string "Minecraft" in it. Once a program that contains the string is executed, the status text will change to "Playing minecraft". Like the PUBG Ransomware, you can name any executable as minecraft.exe and it will trigger the detection.

CSGO Ransomware

The second variant is called CSGO Ransomware and it waits for an executable that contains the string "csgo" to be executed. This program had 7 different variants, with the latest one fixing a bug in the amount of time played being displayed.

Its code, shown below, will properly detect any executable with the string "csgo" in it and increment a timer that is displayed on the screen showing how much time you played the game.

Like MC Ransomware, this program does not encrypt anything.

Ransomware is not a joke

As much as people may find it funny to create programs like this, ransomware is not a joke. Too many businesses and people are harmed by these types of infections and to create this type of program for "educational" purposes or to impress your friends is just irresponsible.

Forget about the fact that someone may accidentally run it and have no idea what to do afterwards, it could have serious legal ramifications for the creator. If a joke ransomware is accidentally, or purposely, installed to a machine and they file a complaint with law enforcement, your little joke may land you in jail.

Be smart people. Don't create malware for educational and joke purposes. No good can come out of it.
