Pewcrypt ransomware (Virus Removal Guide) - Decryption Steps Included

What is Pewcrypt ransomware?

Pewcrypt ransomware – a virus that is created to increase sub count for the famous YouTube star PewDiePie

Pewcrypt ransomware is a file locker that was created in order to make users subscribe to PewDiePie's YouTube channel

Pewcrypt ransomware is a file locking malware that is not created for money extortion purposes, unlike most of the other crypto-viruses are. The author, who is most likely a fan of a popular YouTuber PewDiePie, asks users to subscribe to his channel in order to surpass the sub count of the of Indian channel that uploads Bollywood movie trailers. Allegedly, the hacker claims that decryptor will be released as soon as the favorite YouTuber gets 100 million subscribers. Pewcrypt ransomware is written in Java programming language and uses AES-256 to encrypt data, and then RSA-2048 encryption for the key. Once the process is complete, all pictures, music, databases, documents and other data receives an extension .PewCrypt and becomes inaccessible for victims. Victims of malware are also introduced with a pop-up window which explains what happened to users' data and also displays T-Series and PewDiePie sub count. However, ransomware author, who goes by the name __JustMe__ on Twitter, has released the decryption tool for everybody to use for free.

Considering the immense popularity of this YouTuber (he has been the most subscribed blogger on the platform for over five years), it is not surprising that hackers are creating malware like Pewcrypt or PewDiePie ransomware. However, while in most cases cybercriminals use malicious actions to extort money from users, these viruses do not ask for that. Instead, they want victims to subscribe to PewDiePie.

Being a fan of somebody is OK, but corrupting users' personal files for the sake of the popularity of the YouTuber is purely malicious, and should still be treated negatively. We must give the author credit for releasing the decryptor for free, however. Nevertheless, you need to remove Pewcrypt ransomware before you can use the tool, as all the data will be encrypted repeatedly.

Once the Pewcrypt virus settles, it heavily modifies various Windows settings, spawns multiple processes, attempts to shut down security applications, writes to Windows registry, injects new processes, etc. This ensures that malware will be launched with every system startup.

As soon as file encryption is complete and .Pewcrypt extension is added to most of the files (note that malware skips files larger than 20MB, as well as .exe, .jar and .dll extensions) users can see a ransom note in a pop-up window, which states:

Your files have been encrypted using a 256 bit AES key which has been encrypted with a 2048 bit RSA key

Instructions:
– Subscribe to Pewdiepie (Hint: Hit the bro fist)
– Wait until Pewdiepie reaches 100 million subs at which point a decryption tool will be realseaed

It is up to you whether or not you want to subscribe to the channel, as it will not change to your personally. For the moment, you need to focus on Pewcrypt ransomware removal. In the early stages of the discovery, researchers warned that only 2 AV engines detected the threat.^[1] However, Virus Total results currently show that the malicious file is detected by 30 vendors under names like Trojan.GenericKD.41039316, Ransom_Agent.R002C0OBP19, PUA:Win32/Presenoker, Java/Filecoder.AF!tr., Win32:Trojan-gen, etc.^[2]

Be attentive while browsing the internet to avoid malware infections

Quite often, users do not take cybersecurity seriously, as they are mostly not aware of the consequences that various malware infection can induce to not only computer but also the user.
