Crypton – ransomware virus that returned into the wild several days ago

Crypton ransomware spreaks Russian

Crypton virus is a dangerous ransomware that is targeting Russian, Portuguese and English-speaking computer users. After noticing that your your files cannot be opened and and that they are labeled with specific extensions, you can guess that the ransomware is on your computer. The most popular extension used by Crypton ransomware is “[file_name].id-[victim’s ID]_steaveiwalker@india.com_”. However, having in mind that this virus keeps updating since 2016, you can also see other extensions added to your data as well.

In addition to the encryption procedure, the virus changes computer's desktop background with its ransom note called ”COMO_ABRIR_ARQUIVOS.txt.” Its copies can appear in every single folder on victim's computer. The ransom message typically informs victims about steps that are required to recover encrypted files. From now on, Crypton removal becomes a must-to-do task because new files can also be encrypted if it is kept on the system.

According to the developer of this ransomware, victims must pay 1 Bitcoin if they want to get the decryption key and restore their files. Cybercriminals trick people into paying them by saying that these files are encrypted with high-risk ransomware. However, note that after you fall for their commands and send the ransom, these hackers can vanish away. Keep in mind that there is no guarantee that you will get the decryption key from cyber criminals after making a payment.

To protect yourself, you should discuss no details with hackers and remove Crypton from your computer system with the help of Reimage Reimage Cleaner Intego or similar security software. While you may be convinced that keeping this virus on the system cannot change anything because your files are already encrypted, we must warn you that ransomware may start another round and encrypt another portion of your files. Yet, you can avoid this issue by eliminating this infection without any delay.

Unfortunately, at the moment there are no official tools that could help you restore files encrypted by Crypton. You can try restoring them from backup or by using third party software that is mentioned below this article. To protect yourself in the future, you need to take care of backups of your most important files and also launch occasional system scans to make sure that your system is virus-free.

Crypton virus is still activeCrypton ransomware virus was spotted in 2016. Two years later, it is still actively spreading

Fake software updates and spam emails are used for the distribution of malware

Unsafe download websites, file hosting and sharing sites, and fake software updates, to name the few, are methods used for spreading ransomware around the globe. Also, hackers often employ spam bots to distribute millions of phishing emails that contain malicious attachments. DO NOT open these attachments as malicious payload will be executed straight away. To be particularly safe, delete spam emails without even opening them.

Another helpful habit keeping your software up-to-date. Cybercriminals often use software vulnerabilities to inject their malicious programs into weakened machines. Software developers often release patches that fix these bugs and prevent hackers from using exploit kits.

If your computer is infected with potentially unwanted programs or you often visit suspicious websites, you can encounter fake updates which pretend to belong to legitimate software. Be careful, as these pop-ups might seem real. Therefore, we advise you to enable automatic updates or download them from official websites only.  

Finally, don't forget that every computer should be protected by a certified anti-spyware software with a real-time scanning function. 

Remove Crypton from your computer now

The Crypton virus is a malicious program and needs to be eliminated from your computer as soon as possible. You should be aware that you can easily infect your computer with other malware. Even after you remove Crypton ransomware, your files will remain encrypted. Nevertheless, you can restore them from a backup, using third-party software or trying a free decryptor from Emsisoft. Always start with malware removal – otherwise decrypted files will get contaminated again.

We recommend you use Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes for full Crypton removal. Before you proceed, however, you should enter Safe mode with networking, as explained below (malware can prevent security software from starting).

Bonus: Restore your files

Using the tutorial provided above you should be able to eliminate Crypton from the infected device. novirus.uk team has also prepared an in-depth data recovery guide which you will also find above.

We highly discourage users paying ransom. Instead, use the published decryptor or check third-party apps if it does not work for you. As already mentioned, the safest way to recover data is by restoring it from a backup.

There are a couple of methods you can apply to recover data encrypted by Crypton:

Data Recovery Pro

  • Download Data Recovery Pro;
  • Install Data Recovery on your computer following the steps indicated in the software’s Setup;
  • Run the program to scan your device for the data encrypted by Crypton ransomware;
  • Recover the data.

Windows Previous Versions feature

  • Right-click on the encrypted document you want to recover;
  • Click “Properties” and navigate to “Previous versions” tab;
  • In the “Folder versions” section look for the available file copies. Choose the desired version and press “Restore”.


  • Download Shadow Explorer (http://shadowexplorer.com/);

  • Run the program. Navigate to the menu on the top-left corner and select a disk containing your encrypted files. Look through the available folders;
  • When you find the folder you want to recover, right-click it and select “Export”. Also, choose where the recovered data will be stored.

Use Emsisoft decryptor tool for file decryption

The decryptor by Emsisoft and virus researcher Fabian Wosar is available to download from here

It is strongly recommended to take precautions and secure your computer from malware attacks. To protect your PC from Crypton and other dangerous viruses, you should install and keep a powerful malware removal tool, for instance, Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes.

A proper web browser and VPN tool can guarantee better safety

As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. While browsers cannot create complete privacy and security, some of them are much better because of privacy-oriented services such as sandboxing, active content blocking, phishing protection, HTTPS upgrading, etc.

But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service. This tool successfully reroutes traffic across different servers, so your IP address and location remain protected. It is also important that this tool is based on a strict no-log policy, so no data is collected and cannot be leaked or made available to first or third parties. If you want to feel safe on the internet, a combination of a secure web browser and a Private Internet Access VPN will help you.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. Backing up your files daily or weekly should become your habit.

By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
