Vatq virus – what is it?

Vatq ransomware can correctly be classified as a STOP/Djvu malware family. That sort of computer virus is aimed on individuals. This specification supposes that Vatq does not bring any sort of additional viruses, which sometimes helps ransomware of other families to control your system. Since most users do not have anything valuable , there is no reason to inject other malware that increases the risk of failure of the whole ransomware operation.

The usual signs of that virus activity is the emersion of .vatq files in your folders, instead of the document you used to have. The photo.jpg turns into photo.jpg.vatq, report.xlsx – into report.xlsx.vatq and so on. You cannot to prevent this operation, as well as can’t open these files – they are encrypted with pretty strong cipher.

You can also spectate various other signs of malware activity. Abruptly blocked Microsoft Defender and inability to check the popular anti-malware forums or websites, where the removal and file decryption guides are published. You will see how it is conducted in the paragraph below. The removal and decryption guide are also available – read below how to remove Vatq virus and get the .vatq files back.

How did Vatq ransomware encrypt my files?

After the injection, the Vatq ransomware establishes a connection with its command and control server. This server is controlled by malware maintainers – fraudsters who manage the distribution of this malware. Another activity which is done by these crooks is answering the email messages of victims, who want to decrypt their files.

The files are ciphered with one of the strongest encryption algorithm – AES-256. The “256” digit in the name of this algorithms means the power of two – 2^256 for this case. 78-digit number of possible decryption password variations – it is not real to brute force it. As analysts say, it will need more time than the Earth can approximately exist, even if you use the most powerful computers. In each folder that contains the encrypted documents, Vatq ransomware creates the _readme.txt file with the following contents:

Nonetheless, you can still open some of your files. The Vatq ransomware ciphers only the first 150 KB of each file, but the other piece of this document can be opened. Primarily, it works best with audio/video files, which are surely bigger than 150 kilobytes. Not each media player is able to open these files – WinAmp is the best solution, since it is free and well-tested. First seconds of each recording will be silent – this part is encrypted – but the rest of the video or music will be accessible like nothing happened.

Is Vatq ransomware dangerous for my PC?

As it was mentioned several paragraphs before, ransomware is not only about ciphering the files. Vatq virus makes the changes in your OS in order to prevent looking for the virus removal and file decryption guides. Vatq virus does not establish the software barrier – it just alters the system settings, primarily – networking and security configurations.

Among the networking configurations, the most damaged item is the HOSTS configuration file. This text file has the DNS-address configurations, which are used by the browsers while requesting to the website server. If you add a specific DNS-address for the certain web page, your web browser will connect that site through this DNS next time. Ransomware modifies that file, adding the non-existent DNS, so any of the web browsers will show you the “Unable to resolve the DNS-address” error.

Error 404

Other changes done by the ransomware are targeted on prevention of fast spotting of itself, and also disabling the installation of the majority of anti-malware programs. Vatq malware implements several modifications in Group Policies – the system configuration app which gives you the right to modify the rights of each program. In such a way, malware disables the Microsoft Defender and several other antivirus programs, and also prevents the launch of anti-malware installation files.

How did I get infected?

Throughout the whole term while STOP/Djvu family existed, it was using dubious software as a primary way of ransomware injection. Under the term of questionable programs I mean applications that are already not updated by the maintainer and distributed through the third-party websites. These apps may be hacked, to make them usable without buying any license. One more example of such a program class is various hacking tools – cheat engines, keygens, Windows activation tools and so on.

These software may be spread in many ways – through the website that offers a downloading link, as well as through the peering networks – ThePirateBay, eMule and so on. All these sources are known as the biggest computer piracy resources. Folks use these sites to get a wide range of apps or games for free, even if these apps must be purchased. No one can stop the users who crack these apps from adding viruses of some sort to the files of the hacked app. Hacktools, however, are created for outlaw targets, so their developers can easily insert the ransomware under the guise of some program element.

These cracked apps, regardless of their source, are one of the most often sources for various viruses, and definitely the most used one for Vatq virus. The best solution is to avoid using of it, and not only because of virus installation risks. Avoiding the license buying is an outlaw action, and both hackers and users who use hacked programs fall under the charge of piracy.

How do I remove Vatq virus?

The Vatq ransomware is really hard to wipe out manually. In fact, because of the amount of changes it makes in your system, it is almost unreal to spot them all and fix. The best decision is to use anti-malware software. But which one to choose?

You may read the offers to make use of Microsoft Defender, that is already in your system. But as it was mentioned earlier, the majority of STOP/Djvu virus examples disable it even before the ciphering process. Using the third-party tool is the only possible option – and I can advice you the GridinSoft Anti-Malware as an option for this case. It has perfect detection abilities, so the Vatq ransomware will not be missed. It is also capable of system recovery, that is heavily needed after the Vatq virus attack.

To remove Vatq malware infections, scan your computer with legitimate antivirus software.

  • Download and install GridinSoft Anti-Malware by the button above. After the installation, you will see an offer to start a 6-day free trial. During this term, the security tool has its full functionality, so you will surely be able to both delete the virus and fix your system. To activate a trial period, you just need to type your email address.
  • Free trial activation GridinSoft Anti-Malware

  • After activating the free trial, launch the full scan of your system. It will last for about 15-20 minutes, and check each folder you have in your system. Ransomware will not hide!
  • Full scan in GridinSoft Anti-Malware

  • When the scan is finished, press the Clean Now button to wipe out the Vatq ransomware and all other malware detected by a program.
  • Clean the viruses

    After the ransomware removal, you can go to file decryption. Virus removal is needed to prevent the repeating ciphering of your files: while Vatq ransomware is active, it will not pass any unencrypted file.

    How to decrypt the .vatq files?

    There are two ways to decrypt your files after a Vatq malware attack. First one and the most obvious is file decryption. It is performed with a special app, designed by Emsisoft, and named Emsisoft Decryptor for STOP/Djvu. This program is free. Analysts update its decryption keys databases as often as possible, so you will definitely get your files back, sooner or later.

    Another way to get your files back is to try to recover them from your disks. Since ransomware deletes them and substitutes with an encrypted copy, the residue of the files are still kept on the disk. After the removal, the information about them is removed from the file system, but not from a disk drive. Special programs, like PhotoRec, are able to recover these files. It is free, too, and may also be used for file recovery in case when you have deleted something unintentionally.

    Decrypting the .vatq files with Emsisoft Decrypter for STOP/Djvu

    Download and install Emsisoft Decrypter tool. Agree with its EULA and continue to the interface.

    The interface of this program is extremely easy. All you have to do is to select the folder where the encrypted files are stored, and wait. If the program has the decryption key which corresponds to your ransomware case – it will decrypt it.

    Emsisoft Decrypter decryption process

    During the use of Emsisoft Decrypter for STOP/Djvu, you may observe various error messages. Don’t worry, that does not mean that you did something wrong or a program does not work properly. Each of these errors refer to a specific case. Here is the explanation:

    Error: Unable to decrypt file with ID: [your ID]

    The program does not have a corresponding key for your case. You need to wait for some time until the key database will be updated.

    No key for new variant online ID: [your ID]

    Notice: this ID appears to be an online ID, decryption is impossible.

    This error means that your files are encrypted with an online key. In such a case, the decryption key is unique and stored on the remote server, controlled by crooks. Unfortunately, the decryption is impossible.

    Result: No key for new variant offline ID: [example ID]

    This ID appears to be an offline ID. Decryption may be possible in the future.

    Ransomware uses the offline key to encrypt your files. This key is not unique, so you likely have it in common with another victim. Since offline keys must be collected, too, it is important to keep calm and wait until the analysts team finds one which will fit your case.

    Remote name could not be resolved

    This error indicates that the program has problems with DNS on your computer. That’s a clear sign of malicious alterations in your HOSTS file. Reset it using the official Microsoft guide.

    Recovering the .vatq files with PhotoRec tool

    PhotoRec is an open-source tool, which is designed to recover the deleted or lost files from the disk drive. It checks each disk sector for the remains of deleted files, and then attempts to recover them. That app is able to recover the files of more than 400 different formats. Because of the described feature of ransomware encryption mechanism, it is possible to use this tool to get the original, unencrypted files back.

    Download PhotoRec from the official website. It is absolutely free, however, its developer warns that he does not guarantee that this program will be 100% effective for file recovery purposes. Moreover, even paid apps can barely give you such a guarantee, because of the chain of random factors that can make the file recovery harder.

    Unzip the downloaded archive to the folder you like. Don’t worry because of its name – TestDisk – this is the name of the utility developed by the same company. They decided to spread it together since PhotoRec and TestDisk are often used together. Among the unzipped files, search for qphotorec_win.exe file. Run this executable file.

    PhotoRec and TestDisk

    Before you can start the recovery process, you need to specify several settings. In the drop-down list, choose the logic disk where the files were stored before the encryption.

    PhotoRec recovering choose disk drive

    Then, you need to specify the file formats you need to recover. It may be difficult to scroll all 400+ formats, luckily, they are sorted by alphabetical order.

    PhotoRec file formats

    Finally, name the folder you want to use as a container for recovered files. The program will likely dig out a lot of useless files, which were deleted intentionally, so desktop is a bad solution. The best option is to use the USB-drive.

    After these easy manipulations, you may just press the “Search” button (it turns active if you specified all required parameters). The recovery process may take several hours, so keep patient. It is recommended not to use the computer during this term, since you may overwrite some files you are intending to recover.

    Frequently Asked Questions

    ✔️Are the files encrypted by Vatq virus dangerous?

    No. Vatq files is not a virus, it is not able to inject its code into the files and force them to execute it. The .EXT files are just the same as regular ones, but encrypted and cannot be opened in the usual way. You may store it together with normal files without any fears.

    ✔️Is it possible that antivirus software will delete the encrypted files?

    As I have mentioned in a previous paragraph, encrypted files are not dangerous. Hence, good anti-malware programs like GridinSoft Anti-Malware will not trigger on them. Meanwhile, some of the “disk cleaning tools” may remove them, stating that they belong to the unknown format and are likely broken.

    ✔️The Emsisoft tool says my files are encrypted with the online key and cannot be decrypted. What do I need to do?

    It is very unpleasant to hear that the files you have are likely lost. Ransomware creators lie a lot in order to scare their victims, but they tell the truth in claims about the strength of the encryption. Your decryption key is stored on their servers, and it is impossible to select it because of the strength of the encryption mechanism.

    Try other recovery methods – through the PhotoRec, or using the previously created backups. Search for the previous versions of these files – getting back a part of your dissertation, for example, is better than missing it all.

    Last option is just waiting. When the cyber police caughts the crooks who create and distribute ransomware, first get the decryption keys and publish it. Emsisoft analysts will surely take these keys and add them to the Decryptor databases. In some cases, virus creators may publish the rest of the keys when they stop their activity.

    ✔️Not all of my .vatq files are decrypted. What do I need to do?

    The situation when the Emsisoft Decryptor failed to decrypt several files usually happens when you have not added the correct file pair for the certain file format. Another case when this problem may appear is when some problem occurred during the decryption process – for example, RAM limit reached. Try to perform the decryption process once again.

    Another situation when the Decryptor app may leave your files unencrypted is when ransomware uses different keys for certain files. For example, it may use offline keys for a short period of time when it has connection issues. The Emsisoft tool is not able to check both key types simultaneously, so you need to launch the decryption again, in order to repeat the process.
