Shark ransomware virus. How to remove? (Uninstall guide)

CryptoMix developers update Shark malware

Shark ransomware defines two types of crypto-malware. The first one operates as “Ransomware-as-a-Service” (RaaS)[1] program. The second variation shares the name with the CryptoMix Shark crypto-virus. Speaking of Raas, it has become a trend in the Dark Web. Developers of these malicious programs may offer users to participate in their affiliate campaigns and become official distributors of their fraudulent creations, as in the case of Petya & Mischa RaaS[2].

The above-mentioned sample, CryptoMIx Shark, version follows the manner of another virus, CryptoMix Arena, from the same family as it uses 11 public RSA-1024 keys to encode the AES key which is responsible for encrypting users data.[3] This feature allows the malware to operate offline.

Other improvements are not significant: the demands are presented in the _HELP_INSTRUCTION.TXT. The very message contains scarce information and provides three email addresses: shark01@msgden.com, shark02@techmail.info, or shark003@protonmail.com. Take a look at data recovery instructions. The CryptoMix Decrypter might help you restore affected data.

Speaking of RaaS features, Shark malware is an example of these freely-customizable inventions. According to the service providers, with this free tool, the aspiring hackers can select specific file types they want to target, choose particular folders to encrypt, set the amount of ransom they want to receive for the data decryption and even select the target country.

The Shark ransomware builder package itself consists of three files ReadMe.txt, Payload Builder.exe, and Shark.exe which can only be received directly from the Shark Project’s official page. The finished ransomware is said to be undetectable by the virus-fighting software which already implicates the supposed success.

Nevertheless, in case you got infected, do not panic. You might need to take a few extra steps to decontaminate the virus manually, but we can assure you that professional antivirus software like Reimage or Malwarebytes Anti Malware can remove Shark virus from your computer without much difficulty.

If you have been taking interest in ransomware programs you probably know that their creators are only interested in maximizing their profits. They lock their victim’s files and ask them to pay for the recovery. Even after the payment is made the users are often left stranded without their data and robbed of their money as well.

Thus, it seems that RaaS is also a part of a new plan the scammers came up with to spread their malicious program around the web even wider and earn more illegal profit. The builder also turns out to be paid.

Every 20% of the funds that every Shark-based ransomware collects from its victims will be sent to its original creators. The security experts presume, though, that the Shark developers actually snatch a larger share of the generated profit and the ransomware beginners are exploited simply as virus distributors.

So, either you have become a victim of the already modified virus version or have been involved in its distribution, we strongly suggest you to perform Shark removal immediately. Such dangerous and fraudulent programs do not deserve a place on your computer, and if you use them to generate profit yourself, you should reconsider your priorities.

Prevention tips

Concerning as it sounds, it is virtually impossible to protect your computer from the Shark malware infection a full 100%. But you can decrease this risk by following these steps:

  • Acquire a professional and acknowledged antivirus utility that could prevent you from visiting insecure domains or downloading infected software on your computer.
  • Try to refrain from visiting websites that look suspicious yourself; do not rely on your antivirus only and stay cautious at all times. If you ever end up on a potentially insecure domain, do not download software or fill any surveys and quit the site immediately.
  • Keep away from the spam section in your inbox. Do not open emails received from unfamiliar senders. Most importantly, do not download the added attachments.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Shark from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Shark, you can use several methods to restore them:

What is Data Recovery Pro?

This tool is created for the purpose of restoring damaged or lost files. However, it may come in handy in dealing with Shark Decrypter.

ShadowExplorer option

If you encounter ransomware which does not have a decrypter yet, you might find this tool useful as it uses shadow volume copies to create the copies of your files. However, this tool is only useful if a file-encrypting threat does not delete these copies in advance.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Shark Decrypter

IT experst have not yet created a specific decryption tool for this ransomware variant, but earlier created CryptoMix decrypter by Avast might be of assistance.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Shark and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
