NEQP Virus (.NEQP File) ๐Ÿ” Decrypt & Removal Guide

Written by Brendan Smith
We recently identified a new member of the Djvu ransomware family called Neqp. Neqp, which is a malicious software commonly known as ransomware, encrypts files, rendering them inaccessible to victims. During our analysis of samples on the VirusTotal website, we made the discovery of Neqp.

It’s important to note that Neqp can be distributed alongside other types of malware, including information stealers like RedLine or Vidar. Once Neqp infects a system, it modifies the filenames of encrypted files by adding the “.neqp” extension. For instance, “1.jpg” becomes “1.jpg.neqp” and “2.png” becomes “2.png.neqp“, and so on. Additionally, it leaves behind a ransom note titled “_readme.txt“.

I have compiled a comprehensive list of all possible solutions, tips, and techniques to neutralize the Neqp virus and decrypt your data. In certain situations, file recovery can be relatively easy, while it may be extremely challenging or even impossible in other cases.

Neqp generates a unique key for each victim, with one exception:

  • If Neqp fails to connect with the command and control server (C&C Server) before commencing the encryption process, it utilizes offline keys. This key remains the same for all victims, enabling the decryption of files encrypted in a ransomware attack.

Is Neqp virus?

โ˜๏ธ Neqp can be correctly identified as a Djvu ransomware.

Neqp

๐Ÿค” Neqp virus is ransomware that originates from the DJVU/STOP family. Its primary purpose is to encrypt files that are important to you. After that ransomware virus asks its victims for a ransom fee ($490 – $980) in BitCoin.

The Neqp ransomware, a type of malware, encrypts your files and demands payment to restore them. The following image visually represents files with the “.neqp” extension:

This text asking payment is for restore files via decryption key:

_readme.txt (STOP/DJVU Ransomware)

_readme.txt (STOP/DJVU Ransomware) – The scary alert demanding from users to pay the ransom to decrypt the encoded files contains these frustrating warnings

The Neqp ransomware carries out a series of processes on the victim’s computer to perform various tasks. One of the initial processes it launches is winupdate.exe, a deceptive program that displays a fake Windows update prompt during the attack. This program aims to mislead the victim into thinking that sudden system slowdowns are caused by a legitimate Windows update. At the same time, the ransomware executes another process, usually named with four random characters, which scans the system for targeted files and encrypts them. Additionally, the ransomware uses the following CMD command to delete Volume Shadow Copies from the system:

vssadmin.exe Delete Shadows /All /Quiet

Once these copies are deleted, it becomes impossible to restore the computer to its previous state using System Restore Points. The ransomware operators intentionally eliminate Windows OS-based methods that could facilitate free file restoration. Moreover, the perpetrators modify the Windows HOSTS file by adding a list of domains and mapping them to the localhost IP. As a result, victims encounter a DNS_PROBE_FINISHED_NXDOMAIN error when they try to access any of the blocked websites.

Our observations indicate that the ransomware specifically targets websites that provide how-to guides for computer users. By restricting access to these domains, the criminals aim to prevent victims from accessing relevant and helpful information about ransomware attacks. Additionally, the virus creates two text files on the victim’s computer containing critical details about the attack: the victim’s public encryption key and personal ID. These files are named bowsakkdestx.txt and PersonalID.txt, respectively.

Neqp ransomware virus saves public encryption key and victim's id in bowsakkdestx.txt file

After making all these modifications, the malware doesn’t stop. Variants of STOP/DJVU tend to drop the Vidar password-stealing Trojan on compromised systems. This threat has a lengthy list of capabilities, including:

  • Stealing Steam, Telegram, Skype login/password;
  • Stealing cryptocurrency wallets;
  • Downloading malware to the computer and running it;
  • Stealing browser cookies, saved passwords, browsing history, and more;
  • Viewing and manipulating files on the victim’s computer;
  • Allowing the hackers to perform other tasks on the victim’s computer remotely.

The DJVU/STOP virus uses the AES-256 cryptography algorithm. Therefore, if your documents get encrypted with an online decryption key, it is completely unique. The unfortunate reality is that it is impossible to decrypt the files without the unique key.

If Neqp operates in online mode, it is impossible for you to gain access to the AES-256 key. The key is stored on a remote server owned by the criminals who distribute the Neqp ransomware.

To receive the decryption key, the payment required is $980. To obtain the payment details, the victims are encouraged by the message to contact the frauds by email ([email protected]).

The message by the ransomware states the following information:

ATTENTION!

Don't worry, you can return all your files!

Do not pay for Neqp!

Please, try to use the available backups, or Decrypter tool

_readme.txt file also indicates that the computer owners must get in touch with the Neqp representatives during 72 hours starting from the moment of files were encrypted. On the condition of getting in touch within 72 hours, users will be granted a 50% rebate. Thus the ransom amount will be minimized down to $490). However, stay away from paying the ransom!

I definitely recommend that you do not contact these crooks and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use Decrypter tool.

The peculiarity of all such viruses apply a similar set of actions for generating the unique decryption key to recover the ciphered data.

Thus, unless the ransomware is still under the stage of development or possesses with some hard-to-track flaws, manually recovering the ciphered data is a thing you canโ€™t perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.

Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.

For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main PC is surely not a good idea.

How I was infected?

Ransomware has a various methods to built into your system. But it doesn’t really matter what concrete way had place in your case.

Neqp virus attack

Neqp ransomware attack following a successful phishing attempt.

Nevertheless, these are the common leaks through which it may be injected into your PC:

  • hidden installation along with other apps, especially the utilities that work as freeware or shareware;
  • dubious link in spam emails leading to the virus installer
  • online free hosting resources;
  • using illegal peer-to-peer (P2P) resources for downloading pirated software.

There were cases when the Neqp virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing the Neqp ransomware manually, by actually making you directly participate in this process.

Surely, the bogus update alert will not indicate that you are going to actually inject the ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.

Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Neqp ransomware.

To sum up, what can you do to avoid the injection of the Neqp ransomware into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Neqp penetration. You must be cautious while installing free software today.

Make sure you always read what the installers offer in addition to the main free program. Stay away from opening dubious email attachments. Do not open files from the unknown addressees. Of course, your current security program must always be updated.

The malware does not speak openly about itself. It will not be mentioned in the list of your available programs. However, it will be masked under some malicious process running regularly in the background, starting from the moment when you launch your computer.

How To Remove Neqp Virus?

In addition to encode a victim’s files, the Neqp infection has also started to install the Vidar Stealer on system to steal account credentials, cryptocurrency wallets, desktop files, and more.

  7. Trojan Killer for special instances

    In some certain instances, Neqp ransomware can block the running of setup files of different anti-malware programs. In this situation, you need to utilize the removable drive with a pre-installed antivirus tool.

    There is a really little number of security tools that are able to be set up on the USB drives, and antiviruses that can do so in most cases require to obtain quite an expensive license. For this instance, I can recommend you to use another solution of GridinSoft – Trojan Killer Portable. It has a 14-days cost-free trial mode that offers the entire features of the paid version 5. This term will definitely be 100% enough to wipe malware out.

How To Decrypt .neqp Files?

Restore solution for big “.neqp files

Try removing .neqp extension on a few BIG files and opening them. Either the Neqp infection read and did not encrypt the file, or it bugged and did not add the filemarker. If your files are very large (2GB+), the latter is most likely. Please, let me know in comments if that will work for you.

The newest extensions released around the end of August 2019 after the criminals made changes. This includes Weon, Werz, Vatq, etc.

As a result of the changes made by the criminals, STOPDecrypter is no longer supported. It has been removed and replaced with the Emsisoft Decryptor for STOP Djvu Ransomware developed by Emsisoft.

You can download free decryption tool here: Decryptor for STOP Djvu.

  1. Download and run decryption tool.

    Start downloading the decryption tool.

    Make sure to launch the decryption utility as an administrator. You need to agree with the license terms that will come up. For this purpose, click on the “Yes” button:

    Emsisoft Decryptor - license terms

    As soon as you accept the license terms, the main decryptor user interface comes up:

    Emsisoft Decryptor - user interface

  2. Select folders for decryption.

    Based on the default settings, the decryptor will automatically populate the available locations in order to decrypt the currently available drives (the connected ones), including the network drives. Extra (optional) locations can be selected with the help of the “Add” button.

    Decryptors normally suggest several options considering the specific malware family. The current possible options are presented in the Options tab and can be activated or deactivated there. You may locate a detailed list of the currently active Options below.

  3. Click on the “Decrypt” button.

    As soon as you add all the desired locations for decryption into the list, click on the “Decrypt” button in order to initiate the decryption procedure.

    Note that the main screen may turn you to a status view, letting you know of the active process and the decryption statistics of your data:

    Emsisoft Decryptor - the decryption statistics

    The decryptor will notify you as soon as the decryption procedure is completed. If you need the report for your personal papers, you can save it by choosing the “Save log” button. Note that it is also possible to copy it directly to your clipboard and to paste it into emails or messages here if you need to do so.

The Emsisoft Decryptor might display different messages after a failed attempt to restore your neqp files:

โœ“ Error: Unable to decrypt file with ID: [your ID]
There is no corresponding decryption key in the Emsisoft decryptor’s database.
โœ“ No key for New Variant online ID: [your ID]
Notice: this ID appears to be an online ID, decryption is impossible
Your original files were encrypted with an online key. So no one else has the same encryption/decryption key pair. Recovery of neqp files without paying the criminals is impossible. ๐Ÿ™
โœ“ Result: No key for new variant offline ID: [example ID]
This ID appears be an offline ID. Decryption may be possible in the future.
An offline key was used, but files could not be restored (the offline decryption key isn’t available yet). But, receiving this message is good news for you, because it might be possible to restore your neqp files in the future. ๐Ÿ™‚
It can take a few weeks or months until the decryption key gets found and uploaded to the decryptor. Please follow updates regarding the decryptable DJVU versions here.
โœ“ Remote name could not be resolved
Itโ€™s an indication of a DNS issue on your PC. Our first recommendation is to reset your HOSTS file back to default.

How to Restore .neqp Files?

In some case Neqp ransomware is not doom for your files…

Neqp ransomware encryption mechanism feature is next: it encrypts every file byte-by-byte, then saves a file copy, deleting (and not overriding!) the original file. Hence, the information of the file location on the physical disk is lost, but the original file is not deleted from the physical disk. The cell, or the sector where this file was stored, can still contain this file, but it is not listed by the file system and can be overwritten by data that has been loaded to this disk after the deletion. Hence, it is possible to recover your files using special software.

I recently had my pc infected by the Neqp virus. It managed to bypass 2 Antivirus software and 2 malware fighters.

Anyway, after realizing it was an online algorithm, it is impossible to retrieve my encrypted files. I also had my backup drive plugged in at the time of the virus, and this was also infected, or so I thought. Every folder within my backup drive had been infected and was encrypted. However, despite losing some important files, I retrieved almost 80% of my 2TB storage.

When I started going through the folders, I noticed the readme.txt ransom note in every folder. I opened some of the folders and found that all files that were not in a subfolder within that folder had been encrypted. However, I found a flaw and glimmer of hope when I went into the subfolders in other folders and found that these files had not been encrypted. Every folder within my c and d drives, including subfolders, had been encrypted, but this was not the case with the backup drive. Having subfolders created within a folder has saved 80% of my data.

As I said, I believe this to be only a small loophole on a backup drive. Iโ€™ve since found a further 10 % of my data on another hard drive on a different pc. So my advice is if you use a backup drive, create subfolders. I was lucky, I guess. But I was also unlucky that the virus hit as I was transferring some files from my backup.

Hopefully, this can help some other people in my situation.

Some pointers for recovery repair of Neqp files (true for all STOP/DJVU variants):

  • I have seen Neqp variants fail to encrypt deeper nested folders, so that you can check that. You may find those are not encrypted.
  • This ransomware saves encrypted data to a new file, deletes the original. So thereโ€™s a slight chance part of that deleted file can be recovered using file recovery software. Itโ€™s unlikely the folder structure can be restored, so a free tool like PhotoRec may be as good as any.
  • This ransomware only partially encrypts (about the first 150 KB), so depending on file size and type of data, the not encrypted part may be recoverable.
  • Joep

    Recovering Your Files with PhotoRec

    PhotoRec is an open-source program originally created for recovering files from damaged disks or for file recovery in case they are deleted. Over time, this program has gained the ability to recover files of 400 different extensions, making it suitable for data recovery after a ransomware attack.

    To begin, you need to download this app. It is 100% free, but the developer provides no guarantee that your files will be recovered. PhotoRec is distributed as part of a package with another utility from the same developer called TestDisk. Although the downloaded archive will have the name TestDisk, rest assured that the PhotoRec files are included inside.

    To open PhotoRec, locate and open the file named “qphotorec_win.exe”. No installation is required for this program, as it contains all the necessary files within the archive. This means you can store it on a USB drive and use it to assist your friend, parents, or anyone who has been affected by the DJVU/STOP ransomware.

    PhotoRec file in the folder

    After the launch, you will see the screen showing you the full list of your disk spaces. However, this information is likely useless, because the required menu is placed a bit higher. Click this bar, then choose the disk which was attacked by ransomware.

    Choose the disc in PhotoRec

    After choosing the disk, you need to choose the destination folder for the recovered files. This menu is located at the lower part of the PhotoRec window. The best desicion is to export them on USB drive or any other type of removable disk.

    Choosing the destination folder of recovery

    Then, you need to specify the file formats. This option is located at the bottom, too. As it was mentioned, PhotoRec can recover the files of about 400 different formats.

    Choose the file format

    Finally, you can start files recovery by pressing the “Search” button. You will see the screen where the results of the scan and recovery are shown.

    Frequently Asked Questions

    ๐Ÿค” How can I open “.neqp” files?

    No way. These files are modified by ransomware. The contents of .neqp files are not available until they are decrypted.

    ๐Ÿค” Neqp files contain important information. How can I decrypt them urgently?

    If your data remained in the .neqp files are very valuable, then most likely you made a backup copy.
    If not, then you can try to restore them through the system function – Restore Point.
    All other methods will require patience.

    ๐Ÿค” You have advised using GridinSoft Anti-Malware to remove Neqp. Does this mean that the program will delete my encrypted files?

    Of course not. Your encrypted files do not pose a threat to the computer. What happened has already happened.

    You need GridinSoft Anti-Malware to remove active system infections. The virus that encrypted your files is most likely still active and periodically runs a test for the ability to encrypt even more files. Also, these viruses install keyloggers and backdoors for further malicious actions (for example, theft of passwords, credit cards) often.

    ๐Ÿค” Neqp virus has blocked infected PC: I can’t get the activation code.

    In this situation, you need to prepare the memory stick with a pre-installed Trojan Killer.

    ๐Ÿค” Decryptor did not decrypt all my files, or not all of them were decrypted. What should I do?

    Have patience. You are infected with the new version of STOP/DJVU ransomware, and decryption keys have not yet been released. Follow the news on our website.

    We will keep you posted on when new Neqp keys or new decryption programs appear.

    ๐Ÿค” What can I do right now?

    The Neqp ransomware encrypts only the first 150KB of files. So, MP3 files are rather large, and some media players (such as Winamp) may be able to play the files, but the first 3-5 seconds (the encrypted portion) will be missing.

    You can try to find a copy of an original file that was encrypted:

    • Files you downloaded from the Internet that were encrypted and you can download again to get the original.
    • Pictures that you shared with family and friends that they can just send back to you.
    • Photos that you uploaded on social media or cloud services like Carbonite, OneDrive, iDrive, Google Drive, etc.
    • Attachments in emails you sent or received and saved.
    • Files on an older computer, flash drive, external drive, camera memory card, or iPhone where you transferred data to the infected computer.
