RYK virus
RYK is a ransomware virus which urges for BTC as the ransom price.

RYK ransomware is a file locking threat which relates to the infamous RYUK ransomware virus. This dangerous cyber threat was first discovered by security researchers from the Malware Hunter Team. Once installed, RYK virus performs the encryption process by adding the .RYK appendix to each encrypted document. All files that are locked turn unusable currently. Furthermore, this virus uses RYUK ransomware's note named RyukReadMe.txt. This message urges for Bitcoin as the ransom price and threatens users that no computer shutdowns can be performed, otherwise, encrypted files will be permanently lost. Besides, the cybercriminals provide a way to contact them – CharlstonParkwji@protonmail.com or Huntingdonu@tutanota.com email addresses.

No system is safe

Even though there is no explanation what type of algorithm is used by RYK ransomware, crooks often lock up files with unique encryption algorithms. These codes are very hard to identify even for highly-experienced users as their content is unique and differs every time. Mostly used encryption algorithms are:

  • AES;
  • RSA;
  • SHA.[1]

Despite the fact that the decryption process is a very hard act to perform, you should remove RYK virus from your computer immediately. Do not wait until the ransomware virus brings more unwanted consequences to your computer – other malware injection, deletion of all files, etc. Furthermore, we suggest using Reimage software to detect all hidden components that might be malware-laden and cause system struggles.

Performing the RYK ransomware removal is a hard job that requires a lot of effort. This is the main reason why the elimination process cannot be handled by inexperienced users. Better rely on anti-malware tools and leave the job for them. Additionally, continue reading and find out all precautionary measures necessary to avoid ransomware[2] infections in the future, and how to protect valuable files from possible damage.

Talking about the RYK ransomware ransom price, you should avoid paying it. Crooks often demand cryptocurrencies such as Bitcoin as such transfers do not require any sensitive details and stay completely untrackable. Better overthink every option twice and decide whether it is worth paying the price and taking the risk of getting scammed or not.

Keep your computer and files safe from ransomware infections

According to computer technology experts,[3] the best way to take care of important data is to store it on remote servers or devices. For example, purchase a USB Flash Drive and keep all valuable information in it. If you keep the device unplugged from your computer when it is out of use, the data that is stored in it will be unreachable for anyone, including the cybercriminals.

Talking about the distribution techniques of ransomware viruses themselves, they often are spread via phishing email campaigns.[4] The hazardous payload often comes clipped to the email message. Sadly, some crooks are very good at tricking gullible users as they pretend to send emails from trustworthy organizations. However, after opening an email letter make sure that you were expecting it recently and if it makes sense.

Additionally, malware infections can come from unprotected websites such as P2P networks. These sites are promoted by secondary sources and usually do not fit the security requirements. What you have to do is avoid visiting all third-party websites. Also, a good option would be to install anti-malware protection that will prevent various threats from entering the computer.

Use the below-provided data recovery methods. Complete each step as displayed in the instructions to reach the best results.

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

Data Recovery Pro might help you to restore locked files:

  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Shadow Explorer might be a useful tool:

This third-party software might truly help you to recover some of your data, just make sure that the ransomware did not eliminate Shadow Copies of your files.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
