What is Shrug ransomware? And how does it execute its attack?

Shrug ransomware is one of the latest ransomware discovered on July 6, 2018. This new crypto-malware is one of those typical ransomware infections that only implement a basic ransomware attack. It begins to execute its attack by employing a data gathering module that records all sensitive data in the machine including the user’s data. The data it collects will be processed and used by another component called stealth protection which counters any security programs found in the infected computer to make sure that nothing’s going to stop Shrug ransomware in completing its attack. It then makes modifications in the Windows Registry to achieve persistence and make it hard for victims to terminate it from their PCs.

It then looks for its targeted data and uses a strong encryption algorithm in locking them. It uses the .SHRUG extension in marking its encrypted files. After the encryption, it locks the computer screen which prohibits victims from accessing their computers. The note on the screen states:

“Oh shit waddup ¯\_(ツ)_/¯

I know what you’re thinking. “What happened?”

Well, the answer is quite simple. Before I tell you, promise me you will not get mad. Okay. Your PC was a victim of a Ransomware attack.

That means every important file is now encrypted and you can’t access them. Oh, and there is this screen locker too. You don’t have access to your PC anymore.

What a shame, huh?

There is only one way to get your stuff back. $50. It isn’t that much, cmon! I’ll give you instructions on how to pay. Alright. To successfully pay the ransom and unlock all your sh*t, you will need Bitcoins. But wait, it is only 50 USD in Bitcoins, no worries. Nothing to worry about. You can buy it on the internet.

Oh, and don’t even Google “how to remove a ransomware” because it will not help. When buying Bitcoins you will need a wallet. You can create one at a website called Blockchain. Now find a way to buy 50 USD in BTC. Google is your friend.

Then you must send the Bitcoins to the wallet specified in the right of the screen. After that, write your wallet inside that text box and finally click the button “I paid!”. Wait some time until I confirm your payment and fix your files.

If you are one of the victims of Shrug ransomware, you must not pay the demanded ransom as the files encrypted by this crypto-malware are totally decryptable. But before you do file recovery, you need to terminate Shrug ransomware first.
