Sijr

Sijr uses encryption to lock the users’ files and then blackmail its victim for a ransom payment. Sijr belongs to the file-encrypting subcategory of ransomware.

The Sijr virus file ransom note

PC viruses of the ransomware category are different from most other forms of malware in the sense that they do not seek to harm or steal anything from your computer. If a ransomware virus infects your machine, there will likely be no actual damage done. This, however, doesn’t mean that a ransomware infection isn’t a real problem – quite the opposite. These viruses are actually some of the nastiest malware programs you could possibly encounter.

These cyber threats tend to be really advanced and sophisticated and in many cases even security experts have a hard time handling this kind of malware. There are several important aspects to ransomware threats that need to be pointed out in order to get a good idea about the nature of these viruses and we will go over those aspects in a moment. For now, what you need to know is that Sijr is one of those cryptoviruses and if you have landed this threat on your computer, you should probably read the rest of this article as the information included here might help you minimize harm of this malware piece.

The Sijr virus

Variants like the Sijr virus will normally target your files in an attempt to lock them up and then blackmail you for a ransom payment if you want to receive the key that can unlock the sealed data. The use of encryption is an important element that needs to be factored in since this is one of the main reasons behind the high success rate of ransomware like the Sijr virus.

The encryption process used by viruses such as Sijr, Hhjk, Jhgn, Mmob is not harmful to anything on the targeted machine. Sure, it locks the files but they are still intact. The lack of any real harm, however, typically allows the virus program to stay under the radar as it would trigger pretty much no symptoms during the ongoing encryption process. Even if you have an antivirus program on your PC, there’s no guarantee that it would notice the threat precisely because no actual damage is being inflicted on anything inside the PC system.

The Sijr file encryption

Once the Sijr file encryption is over and all selected data has been rendered inaccessible, the user is asked to make a payment. The payment is in order to “purchase” the decryption key for the Sijr file decryption.

Now, here comes the question if it is actually a viable idea to go for the payment if the requested sum isn’t too high. Well, we can’t tell you what to do but what we can tell you is that even if you pay, that is no guarantee that the files on your computer would get unlocked. After all, the hacker might decide to keep the key to themselves and not send it to you even after you have paid. There are more than enough real-life examples of this happening. There, however, are alternative solutions you can try. One such possible alternative is the Sijr removal guide posted on this page. You can use it and see if it works and while we can’t promise you that it will bring everything back to normal, it is still worth giving it a go before you decide to risk your money by sending it to the hackers in hopes of getting the decryption key.

A ransomware threat such as Sijr can be difficult to detect. What is more, if left unresolved, this danger has the potential to do considerable damage to the system over an extended period of time.

As soon as this ransomware has infected your computer, one of the most difficult challenges you’ll have to confront is recognizing and stopping its malicious processes. That’s why, to ensure the safety of your computer, we highly recommend that you follow the instructions below with attention to every detail.

On your computer’s keyboard, press CTRL+SHIFT+ESC. You’ll see a Windows Task Manager window on the screen. Click on the Processes tab and search for processes that might be related to the ransomware. If you isolate a process that looks suspicious, right-click on it and then select “Open File Location” from the quick menu.

You can use the free online scanning tool given below to ensure that the files associated with this process are clean of any possibly dangerous code.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    The right-click menu can be used to end the associated process if the scanner identifies a risk in any of the scanned files. Once you’ve ended the suspicious process, go back to the infected files and delete them.

    Next, we’ll explain to you how to get rid of any potentially harmful startup items that might still be on your computer. This can be done by opening the System Configuration window. System Configuration can be found by typing msconfig in the Windows search bar. You will see a number of start-up items shown on the Startup tab:

    Unchecking any startup items associated with the ransomware should be your first concern. Look for startup items that aren’t generally linked with the applications that normally start when the system boots up. Uncheck their checkboxes if you find adequate evidence to support their deactivation. Don’t disable any operating system or trustworthy program components while doing this, though!

    In this step, you will need to delete any dangerous registry entries identified in your registry editor in order to eradicate the ransomware and ensure that it does not reappear or leave any hazardous components behind.

    The Registry Editor can be launched by searching for it in the Windows search bar and pressing Enter. You can search for ransomware-related files in the Registry Editor by using the CTRL and F keyboard keys combination. Just type the name of the ransomware in the Find box that appears inside the Editor and then click Find Next. Right-clicking on a potentially harmful entry will remove it.

    Attention! Remove only the registry entries that are linked to the ransomware infection. If you alter the registry or remove anything unrelated to the threat, you risk damaging your system and installed programs. If you find yourself in trouble and are not sure that needs to be deleted, this article contains a link to a professional malware cleanup tool that can assist you in the removal of the Sijr ransomware and other malicious software from your PC.

    Another thing we recommend you to do, after cleaning the Registry Editor,  is to manually search the locations listed below for any other potentially hazardous files and subfolders. Using the Windows search bar, type the name of the location you want to open and click Enter.

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Any suspicious-looking files or subfolders that have been recently added to each of the locations above should be properly investigated. It is also a good idea to empty the Temp folder and delete everything within to ensure your PC is free of any potentially hazardous temporary files.

    The next step is to look for any malicious modifications to the Hosts file on your machine. After launching the Run dialog box (by pressing the Windows key and the R key at the same time), copy/paste the following command in the Run box, and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    If, as shown in the sample screenshot below, the Hosts file contains a number of questionable IP addresses under “Localhost“, please let us know in the comments. If you detect any other changes in your Hosts file or have any questions or concerns, please do not hesitate to contact us.

    How to Decrypt Sijr files

    It is possible to try a variety of methods to decrypt encrypted files after a ransomware attack has occurred. Depending on the variant that has infected you, there are some file-restoration options may not work. Therefore, the first thing you need to know when deciding how to recover your files is the variant of Ransomware you’re dealing with. This information can be accessed from the encrypted files by looking for newly-added file extensions.

    New Djvu Ransomware

    STOP Djvu Ransomware is one of the most recent versions of the Djvu ransomware. You may have been infected by this variation if your encrypted files have the .Sijr file extension at the end.

    If this ransomware’s encryption relies on an offline key, then those who have had their data encrypted may have some hope of recovering it. There is a file decryption tool available for this specific ransomware variant if you click on the link below.
