Why should you worry about PUBG Ransomware?

PUBG Cryptovirus will encrypt your data but is suspected to be a kind of prank program for it demands the victim to play a game in order to decrypt the files locked by it. The PUBG Ransomware Virus is similar to RensenWare Ransomware which also required the users to play a certain game to restore the files back. The ransom instructions on the ransom note state two ways to decrypt the files, one of which requires the user to play the game known as “PlayerUnknown’s Battlegrounds”. The developers seem to have no intention to extort money from the users but just have fun by making them play this multiplayer online battle royal game. The victim is instructed to play the said game for an hour so as to be able to decrypt the files. The ransom note presented by the PUBG Ransomware screen states the following:

PUBG Ransomware

Your files, images, musics, documents are Encrypted!

 

Your files is encrypted by PUBG Ransomware!

But don’t worry! It is not hard to unlock it.

I don’t want money!

Just play PUBG 1 Hours!

Or Restore code is [s2acxx56a2sae5fjh5k2gb5s2e]

 

The message as given above clearly states two methods to restore the data that has been decrypted by the Ransomware. The first one is to play the game for which the running process is overseen by the malware so as to check, if the game is being played. But since the malware is not that advanced, it simply checks the running process of the game called “TslGame.exe”. Though the note instructs the users to play the said game for an hour but the users will be able to decrypt the files just after running the executable file for merely 3 seconds. The decryptor is activated as soon as it detects the running process and the user is able to restore all the data encrypted. The second one is to enter the given decryption code (s2acxx56a2sae5fjh5k2gb5s2e) if the user doesn’t wish to play the game.

 

How did PUBG Rasomware get  installed on your PC?

The cybercriminals use various strategies for malware distribution which include –

  1. Software Bundling: Software bundling is the process in which a malicious program is distributed with other free software, to get an unnoticed entry into your computer system. When a user installs a free application, the malicious programs gains a front door entry with the free application, the user has downloaded.

These attachments can be named as anything which can grab the user’s attention and triggers him/her to open the attachment. As soon as the user opens this attachment, the malware infects the user’s computer system.
