What is Tsar ransomware?

Tsar ransomware – a file locking virus that threatens to delete decryption key after five days

Tsar ransomwareTsar ransomware is a file locking virus which is also a variant of BlackHeart malware

Tsar ransomware is a type of malware that focuses on money extortion from victims after encrypting all pictures, documents, videos, music, databases, and other files on the targeted computers. As pointed out by security researcher dnwls0719 on Twitter who first spotted the threat in the wild, it appends .Tsar extension to each of the files, and then drops “ReadME-Tsar.txt” ransom note on the desktop, as well as other folders on the system. Additionally, Tsar virus also shows a pop-up window – it claims that the data was locked with the combination of RSA, AES, and ChaCha20 algorithms[1] and that the only way to recover it is by paying the ransom of $1,000 in Bitcoin cryptocurrency.

Crooks behind Tsar ransomware claim that if they are not contacted via MR_Liosion@protonmail.com or Decrypt.Russ@protonmail.com emails within five days, the unique decryption key will be permanently deleted. While it is unclear whether such a scenario is plausible, paying threat actors is not recommended, and they might not send the required Tsar ransomware decryption tool.

Data decryption

The only secure way to retrieve data without paying the attackers is using backups. If none are available other solutions include:

  • using third-party recovery software (low success rate)
  • paying ransomware authors (not recommended)
  • waiting for the decryption tool to be developed
Malware removal To get rid of malware and all its components, scan your computer with anti-virus software such as SpyHunter 5Combo Cleaner or Malwarebytes. If unsuccessful, access Safe Mode with networking as explained in the instructions below
System fix In case your Windows operating system starts crashing, lag, or suffer from other stability issues after malware elimination, use FortectIntego to fix virus damage

Tsar ransomware stems from the BlackHeart malware family, which was first spotted back in April 2018. While the strain is not extremely prevalent, the attackers released a few versions over the years, including BlackRouter, Prodecryptor, and a few others. Despite low prevalence, those infected with Tsar ransomware can suffer devastating consequences, as the encryption algorithm used is secure, and no known free decryption tools are currently available.

Tsar file virus targets Windows operating systems and uses a variety of methods to reach them. For example, the attackers might employ malicious spam email attachments/hyperlinks to deliver the payload, as well as exploits, fake updates, software cracks, and other ways. To protect yourself from ransomware infections in the future, check the tips in our malware distribution paragraph below.

Before performing the data locking process, the Tsar virus also modifies Windows in a variety of ways, e.g., deletes Shadow Volume Copies to prevent easy data recovery, modifies Windows registry for persistence, drops a variety of malicious files, disables certain processes and services, etc.

Tsar ransomware typically targets the most common file types, such as .doc, .jpg, .txt, .dat, .mp4, .html, and others, although it skips the most vital Windows system files for it to operate. After the data locking process, a pop-up message shows up immediately, which reads:

You Are Crypted!

What's Happened to my computer?
You Are Crypted By RSA And AES And ChaCha20 Encryption And Not Recovered!
Your important files are encrypted.
Many of your documents,photo,video,database,project
and other files are no longer accessible because they have
been encrypted. maybe you are busy looking for a way to
recover your files, but do not waste your time. nobody can

While it is unknown whether the decryption tool will actually be deleted, many security experts recommend not trusting ransomware authors, as they might demand money after the first payment, or ignore the request completely. Instead, it is better to focus on the Tsar ransomware deletion process.

Tsar ransomware virusTsar ransomware is crypto-malware that locks all personal files with a strong encryption algorithm and then asks for $1,000 in Bitcoin for the decryption software

Most of the anti-malware solutions recognize the malicious executable SF.exe that populates the Tsar virus as follows:[2]

  • Trojan-Ransom.FileCrypter
  • Ransomware-GMZ!E6491ED91A5A
  • Mal/Ramsil-T
  • Ransom.Tsar
  • Generic.Ransom.WCryG.256E2920
  • Trojan:MSIL/Filecoder.DSK!MTB
  • Win32:RansomX-gen [Ransom], etc.

It goes without saying that a comprehensive anti-malware can not only remove Tsar ransomware from the system but also protect it from its intrusion in the first place. As previously stated, there is no working decryption tool available, so the only safe method of data recovery is via backups.

Nevertheless, it is also important to mention that Tsar ransomware removal will not recover your data, as encryption is a separate process that occurs due to malware infection, but it is not reversible unless a unique key is acquired. Thus, simply backup locked files, get rid of malware with anti-virus software and only then try alternative recovery methods listed below. If your system suffered significant damage and Windows starts crashing or malfunctioning otherwise, use FortectIntego repair tool to fix virus damage.

Apply comprehensive security measures to avoid ransomware infections

Ransomware is most definitely one of the most devastating malware types in the wild. It is not only dangerous for home users who might lose precious personal photos or work files but also disastrous for corporations, businesses, and local governments. While the spread of the threat and the popularity of it has been rising in the past years, cybercriminals are constantly coming up with new ways of making victims pay ransoms.

For example, major ransomware distributors behind Maze, Sodinokibi, DoppelPaymer, Nemty, and others are now threatening to publish stolen sensitive information from its victims.[3] Therefore, ransomware has huge implications, and the recovery process might be complicated (in some cases, data recovery might be completely impossible), so it is best not to get infected in the first place.

Security experts from Novirus.uk[4] advice users to practice these precautionary measures in order to reduce the infection chances to a minimum:

  • Employ next-gen security software with machine-learning and other advanced features that can prevent ransomware from entering;
  • Update your operating system and all the installed apps as soon as security patches are deployed;
  • Never download software cracks/keygens or pirated program installers;
  • Do not allow an attachment acquired via a suspicious email to run macro commands (“Allow content”) on your system;
  • Enable anti-spam and anti-phishing tools, as well as ad-blocking extension;
  • Protect all your accounts with secure alphanumeric passwords or use a password manager;
  • Never use default TCP port for your Remote Desktop connections and disable the feature as soon as it is not used anymore.

Additionally, make sure you backup all your most important files on a cloud or an external storage device such as USB/external HDD.

Tsar ransomware encrypted filesUnfortunately, once Tsar ransomware performs the encryption process, recovering data without having backups is difficult

Delete Tsar ransomware securely

In many cases, users who get infected with ransomware do not know how to proceed next, and whether their files can be saved. Because the Tsar virus does not have a working decryption tool, recovering data without paying criminals is highly unlikely, although not impossible. Therefore, you should remove Tsar ransomware and then try applying alternative methods we provide below; maybe ransomware failed to delete Shadow Volume Copies, and you will be able to retrieve everything with ShadowExplorer.

Nevertheless, before you perform Tsar ransomware removal, you should copy over all the encrypted data, as malware termination might permanently damage your data, and even threat actors will not be able to help you. For that, employ anti-malware software – scan your computer in Safe Mode if the normal mode does not suffice. Note that while there are many AV engines that detect the threat, not every anti-malware will be able to terminate the virus, so you might have to employ several removal tools.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Tsar 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 Tsar, you can use several methods to restore them:

Data Recovery Pro method may be successful in some cases

Data recovery software may sometimes be effective, as it may be able to extract working copies of some of your files on the hard drive.

  • 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 Tsar ransomware;
  • Restore them.

Previous Windows Versions feature can help you with individual files

This method can only be used on files one-by-one, and only works if the System Restore point was established before ransomware struck.

  • 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 might suffice

In case of Tsar file virus failed to get rid of Shadow Volume Copies, this still should be able to retrieve most, if not all, 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.

No decryption software is currently available

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

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
