Sardoninir ransomware appends an extension to files and prevents victims from accessing them

The screenshot of Sardoninir malwareSardoninir ransomware urges you to pay the ransom before the time runs out.

Sardoninir virus happens to be another file-encrypting computer program[1]. It is another example of ransomware which threaten users into remitting the payment within the specified amount of time[2]CryptoWall or WannaCry are one of the more prominent examples of such strategy.

Once installed, malware rushes to encrypt all data on the system with AES encryption algorithm, which also applies the .enc extension to the them. Suchlike files can then no longer be accessed or modified. Malware then drops a ransom note window which includes the timer of 24 hours and a demand to pay $100 worth of cryptocurrency.

The ransomware market is full of vivid file-encrypting threats varying in their design, operation modes, the degree of complexity, etc. Fortunately, there are few highly destructive threats. However, they are able to wreck a serious damage worldwide. Speaking of this malware strain, it follows the basic operation pattern.

Though it is still under development, it hides its payload in spam emails[3]. After that, it encrypts the files with a strong algorithm which generates a unique complex key. It results in locking all your important data and attaching .enc file extension to each affected file.

At this stage, the ransom message appears alarming you with the elapsing clock. It instructs the victims to pay the ransom in return for the decryption key. In case you intend to contact the crooks, they provide email address.

You might try paying the ransom but it does not give any guarantees that the crooks will return the files. On the other hand, they may just ignore your plea for mercy. The malware is still suspected to be under development so the virtual community should be vigilant. Instead, proceed to Sardoninir removal.

Ransomware distribution techniques

Ransomware authors devise new ways to break through into users’ computers. Usually, they do so by forcing them to open corrupted spam emails[4]. This is when the infection of ransomware takes over the computer. In addition, you should be aware of trojans and other sorts of malware that serve as mediators for the ransomware to enter your device.

Exploit kits often perform such a role. Therefore, you should be careful not only while browsing online but arm up with proper security applications. It would be better to combine anti-virus and malware removal utility. Update them and run the scan, the latter will help you remove all malware as well.

Bonus: Recover your data

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

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

What is Data Recovery Pro program?

It is the tool which is devised to help users to retrieve lost and damaged files. It is also practical in restoring deleted emails and files in data storage devices.

  • 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 Sardoninir ransomware;
  • Restore them.

How useful is Windows Previous Versions feature?

This function only works if System Restore is enabled. Though it is more time-consuming since you have to go through all the affected files by the virus, you might succeed in recovering some of them.

  • 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”.

ShadowExplorer method

This program uses shadow volume copies to recover lost data. There are no reports whether malware deletes them, so the chances to recover the files are higher.

  • Download Shadow Explorer (;
  • 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.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Sardoninir 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.
