This malware encrypts your files unless you play PUBG

Yes, you read the title correctly. MalwareHunterTeam has discovered a new malware that calls itself “PUBG Ransomware“. It locks your files and gives you two options of decrypting them — Play PUBG for one hour, or enter the restore code.

The ransom screen states that you need to play the game for an hour, but it actually only checks your running processes for “TslGame.exe”, so you actually only need to have it running for a few seconds. Any .exe named TslGame will also work

Of course, if you’re not in the mood for some battle royale action, you can simply enter “s2acxx56a2sae5fjh5k2gb5s2e” in the ‘Restore code’ dialog box shown in the ransom screen.

Looking at how PUBG Ransomware actually works, it’s not really intended to be a harmful piece of malware, and is better suited to be called jokeware.
