What is Tsar ransomware?

Discovered by dnwls0719, Tsar is the title of a malicious program, classified as ransomware. It operates by encrypting the data of infected systems and demanding payment for the decryption. During the encryption process, all affected files are appended with the ".Tsar" extension. For example, a file like "1.jpg" would appear as "1.jpg.Tsar" - following encryption. After the encryption is complete, a pop-up window is displayed and a text file - "ReadME-Tsar.txt" is created on the desktop. Both the pop-up and text file contain ransom notes.

The pop-up informs victims that their data has been encrypted with RSA, AES and ChaCha20 cryptographic algorithms. The note states that the only method to restore it - is to purchase the decryption tools/software from the cyber criminals behind Tsar ransomware. To do so, users are instructed to establish contact with the criminals via email (this can be done using the appropriate fields in the pop-up window) and pay 1000 USD. The window has a countdown and once the time runs out - the price will double. The ransom-demanding message in "ReadME-Tsar.txt" file clarifies that the ransom has to be paid in Bitcoin cryptocurrency (the text file also has links leading to sites detailing how to and from where to acquire Bitcoins). Decryption will be available for five day, afterwards the decryption key will be deleted. Hence, victims are urged to make the payment as soon as possible, else they risk losing their data. Before paying, users can test decryption by sending the cyber criminals one encrypted file. The test file cannot contain important information; however, it can be in .jpg, .png, .txt and similar formats. This note warns users that using third party decryption tools and/or running an anti-virus program - will result in permanent data loss. Unfortunately, in most cases of ransomware infections - without the interference of the individuals responsible - decryption is impossible. It might be, if the malware is still development and/or has bugs/flaws. Regardless, it is expressly advised against meeting the ransom demands. Often, despite paying - victims do not receive the necessary tools/software to decrypt their files. Therefore, the compromised data remains encrypted and users' experience significant financial losses. To prevent Tsar from further encryptions, this malicious program must be removed from the operating system. However, removal will not restore already affected files. The only viable solution is recovering the data from a backup, if one was created prior to the infection and was stored in a separate location.

SepSysMaMo434376Pxj and MARRACRYPT are a couple examples of other ransomware-type programs. Malware classified as such is designed to encrypt data and demand a ransom to be paid for the appropriate decryption tools/software. Ransomware has two main differences in-between: the cryptographic algorithm (symmetric or asymmetric) used for the encryption and the demanded payment size. Digital currencies (primarily, cryptocurrencies) are used for the ransoms, due to transactions of them being difficult/impossible to trace. To avoid permanent data loss, it is recommended to keep backups in remote servers and/or unplugged storage devices.

How did ransomware infect my computer?

The most common proliferation methods of ransomware and malware are via trojans, spam campaigns, software "cracking" tools and fake updates, as well as untrustworthy download channels. Trojans are malicious programs, capable of causing chain infections (i.e download/install additional malware). Spam campaigns are used to send thousands of deceptive emails with infectious files attached to (or linked inside) them. Virulent attachments can be in a variety of formats (e.g. archive and executable files, PDF and Microsoft Office documents, JavaScript, etc.) and when they are opened - it initiates the infection. Rather than activate the desired product, illegal activation ("cracking") tools can download/install malware. Illegitimate updaters cause infections by exploiting weaknesses of outdated software and/or by installing malicious programs instead of the promised updates. Download sources like: unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders - are considered to be untrustworthy and can offer malicious content for downloading.

How to protect yourself from ransomware infections?

Dubious and/or irrelevant emails should not be opened, especially any attachments or links present in such mail - as that can result in a high-risk infection. All downloads should be done from official and verified sources. It is recommended to only activate and update products with tools/functions, provided by genuine developers. Illegal activation tools ("cracks") and third party updaters - can download/install malicious programs; therefore, they are advised against use. It is crucial to have a dependable anti-virus/anti-spyware suite installed and kept up-to-date. This software is to be used to perform regular system scans and to remove all detected/potential threats. If your computer is already infected with Tsar, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Tsar ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Tsar ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Tsar are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Tsar, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Tsar ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
