AZQT Virus (.AZQT File) 🔐 Decrypt & Removal Guide

The Azqt virus, also recognized as ransomware, belongs to the STOP family. This malware family is notorious for encrypting files maliciously. When the Azqt virus infiltrates a computer system, it scans the system for files such as photos, videos, documents, and more. It alters the file structure and appends the “.azqt” extension to each encrypted file, rendering them unusable without the decryption key.

Azqt Virus Overview

The Azqt virus is a type of malware that encrypts your files and makes you pay for their decryption. This ransomware ciphers different file types. Encrypted files are identifiable by a distinct “.azqt” extension. The files touched by ransomware become impossible to access and use.

After that, the ransomware asks for a file decryption payment in Bitcoin from the victims, ranging from $490 to $980. Usually, a ransom text file is named as “_readme.txt“.

Azqt Ransomware uses Salsa20 encryption algorithms to scramble the contents of the targeted files. Since Azqt virus utilizes such a robust encryption method, it becomes incredibly hard, if even possible, to pick the decryption key without cooperating with the attackers.

Once Azqt malware finishes the encryption, it shows a ransom note to the victim, asking for a ransom payment in exchange for the decryption key. The ransom note provides instructions on the ways of making the payment and also often contains threats of permanent data loss or ransom amounts surge if the ransom is not paid within a specified timeframe.

I have made an all-encompassing list of the solutions, advice, and methods to neutralize the Azqt malware and decrypt and recover your files. There are cases when you can regain access to the files, while sometimes, it may be impossible.

Azqt uses a unique key for every victim, with one exception:

• If Azqt fails to establish a connection with its command and control server (C&C Server) before starting the encryption process, it resorts to using offline keys. An offline key is not unique and is the same for all users, which allows for the decryption of files encrypted by the ransomware.

The Azqt virus bears resemblance to other DJVU ransomware samples like Azhi, Wwhu, Wwpl, and Wwty. This virus encrypts a wide range of common file types and appends its distinct “.azqt” extension to all files. For instance, a file named “1.jpg” would be altered to “1.jpg.azqt” and “2.png” to “2.png.azqt“.

After successful encryption, AZQT creates a special text file named “_readme.txt” and places it in every folder containing the encrypted files. It also adds this file to the desktop, so the victim will not miss the attack even without opening folders.

The image below provides a visual representation of files with the “azqt” extension:

Encrypted Files by STOP/DJVU Ransomware

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

_readme.txt (STOP/DJVU Ransomware) – The terrifying warning demanding users to pay the ransom to decrypt the encoded data contains these exasperating admonitions.

Azqt ransomware arrives as a set of tasks that are meant to execute certain functions on a victim’s computer. One of the initial processes being launched is winupdate.exe, a sneaky process that displays a false Windows update alert during the attack. Such a trick helps to convince the victim that their PC has become slow because of a Windows update.

At the same time, the ransomware runs another process (named as 4 random chars) which commences scanning the system for target files and ciphering them. Then the ransomware deletes Volume Shadow Copies from the system using the following CMD command:

vssadmin.exe Delete Shadows /All /Quiet

Once removed, it becomes virtually impossible to retrieve the previous computer state using System Restore Points. The problem is, ransomware operators are getting rid of any built-in Windows approaches that could assist the victim to recover files for free. In addition, the crooks modify the Windows HOSTS file by including a list of domains to it and linking them to the localhost IP. As a result, the victim will witness a DNS_PROBE_FINISHED_NXDOMAIN error when accessing one of the blacklisted websites.

We noticed that ransomware tries to block websites that publish various how-to guides for computer users. It is evident that by hindering specific domains, the malefactors are trying to stop the victim from reaching relevant and helpful ransomware-attack-related information online. Malware also keeps two .txt files on the victim’s computer that present particulars related to the attack – the public key of this victim and personal ID. These two files are named bowsakkdestx.txt and PersonalID.txt.

After all these modifications, the malware doesn’t cease. Variants of STOP/DJVU tend to install Vidar password-stealing Trojan on compromised systems. This threat has an huge list of capabilities, including:

• Gathering sensitive data by running malicious software on the victim’s computer.
• Acquiring unauthorized login credentials of Steam, Telegram, and Skype accounts.
• Manipulating and viewing files on the victim’s computer without their knowledge.
• Stealing cryptocurrency wallets from the victim’s system.
• Granting the hackers remote control over the victim’s computer for various malicious activities.
• Extracting sensitive information such as browser cookies, saved passwords, and browsing history.

The cryptography algorithm used by DJVU/STOP virus is AES-256. So, once your data is encrypted with an online decryption key, the possibility to get your files back without paying the ransom are quite low. Thing is, this key is unique for each victim, and finding a suitable one will take too much time.

Retrieving the online key in another way is also merely impossible. It is kept on a remote server owned by the criminals who promote the Azqt infection. For receiving decrypting code the payment should be $980. To obtain the payment details, the victims should contact the fraudsters by email (support@fishmail.top).

The message by the ransomware states the following information:

ATTENTION!

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

Do not pay the ransom!

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

The _readme.txt document also requests that the computer owner must get in touch with the hackers within 72 hours since the file encryption. If user contacts hackers within 72 hours, hackers grant a 50% off. This decreases the ransom sum down to $490.

Yet, stay away from paying off the ransom! I highly recommend that you do not contact these fraudsters and do not pay. One of the most real working solution to retrieve the lost data is just using the available backups, or using Decrypter tool from Emsisoft.

The peculiarity of all such viruses is the application a similar set of actions to generate the unique decryption key. Thus, unless the ransomware is still under the stage of development or has some hard-to-track flaws, manual data recovery is a thing you can’t perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your critical files.

Remember that even if you do create such backups regularly, they ought to be placed 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 optional external hard drive storage. Optionally, you may turn to the help of online (cloud) information storage.

It goes without saying, when you maintain your backup on your regular device, it may be ciphered together with other data. For this reason, storing the backup on your main computer is surely not a wise idea.

How I was infected?

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

Ransomware attack following a successful phishing attempt.

However, these common leaks may inject it into your PC:

• Online free hosting resources can be used to distribute the virus undetected.
• The virus installer disguises itself alongside various apps, particularly those offered as freeware or shareware.
• The virus spreads through spam emails containing deceptive links that lead to its installation.
• Obtaining pirated software from illegal peer-to-peer (P2P) resources exposes users to potential malware threats.

Cases have occurred where the Azqt virus disguised itself as a legitimate procedure, such as messages requesting the installation of a browser update or a much-needed codec for online media playback. This is commonly how some online frauds aim to force you to install the ransomware manually, by actually making you directly engage in this process.

Surely, the bogus update alert will not inform you that you are installing the threat. This installation will be concealed under some alert stating that you must install an urgent security update or some questionable program.

Undoubtedly, cracked apps also pose a threat. Using P2P is both illegal and may result in the introduction of serious malware, including the Azqt ransomware.

In summary, what can you do to prevent the ransomware from penetrating your system? Although there is no 100% guarantee to thwart your PC from getting compromised, there are some tips I want to give you to shield against Azqt penetration. You must be careful when installing free software today.

Make sure you always read what the installer offers aside from the main free program. Keep away from launching suspicious email attachments. Do not run files from unknown senders. Certainly, your current security program must always be updated.

The malware does not openly state its presence. It will not appear in the list of your available programs. Instead, it will be masked under some malevolent process running consistently in the background, starting from the moment you boot up your computer.

How to Restore .azqt Files?

In some case ransomware is not doom for your files…

The Azqt ransomware encryption mechanism sequence is next: it encodes every file byte-by-byte, then saves a duplicate, deleting (not overriding!) the initial file. Thus, the data 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 kept, can still hold this file, but it is not listed by the file system and can be replaced by data that has been loaded to this disk after the deletion. Hence, it is possible to retrieve your files using special software.

Recovering your files with PhotoRec

PhotoRec is an free program, which is originally created for file retrieval from damaged disks, or for file retrieval in case if they are unintentionally deleted. However, as time has gone by, this program adopted the ability to recover the files of 400 different file types. Hence, it can be used for file restoration after the Azqt attack.

First, you need to download this app. It is 100% free, but the developer notifies that there is no warranty that your files will be restored. PhotoRec is spread in a pack with other utility of the same developer – TestDisk. The resulting archive will bear TestDisk name, but don’t worry. PhotoRec files are right inside.

To launch PhotoRec, you need to find and open “qphotorec_win.exe” file. No installation process is required – the program has all the files it need inside of the archive, hence, you can mount it on your USB drive, and help your friends/parents/anyone who has been attacked by Azqt ransomware.

After the start, you will observe the screen showing you the complete list of your disk drives. However, this data is probably futile, because the required menu is placed a bit higher. Click this bar, then choose the disk which was attacked by ransomware.

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

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

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