What is RYK ransomware?

RYK ransomware – a virus related to RYUK ransomware

RYK virusRYK 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.

Crooks who spread RYK ransomware also claim that Shadow Volume Copies have been removed and hitting the f8 key will only make more damage:

Your network has been penetrated.

All files on each host in the network have been encrypted with a strong algorithm.

Backups were either encrypted
Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover.

We exclusively have decryption software for your situation.
More than a year ago, world experts recognized the impossibility of deciphering by any means except the original decoder.
No decryption software is available in the public.
Antiviruse companies, researchers, IT specialists, and no other persons cant help you encrypt the data.

DO NOT RESET OR SHUTDOWN – files may be damaged.
DO NOT DELETE readme files.

To confirm our honest intentions.Send 2 different random files and you will get it decrypted.
It can be from different computers on your network to be sure that one key decrypts everything.

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 FortectIntego 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.

Bonus: Recover your data

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

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:

Use this tool to recover documents that were locked by the ransomware virus.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by RYK ransomware;
  • Restore them.

Maybe Windows Previous Versions feature will help with file recovery:

We suggest trying this tool if you have enabled the System Restore function before the virus managed to enter the system and lock files.

  • Find an encrypted file you need to restore and right-click on it;
  • 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;
  • 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.

Sadly, no official RYK virus decryptor has been released by cybersecurity experts recently.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from RYK and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
