What is Qazx Ransomware

Qazx Ransomware is called so, because of .qazx extension, added to affected files, modifying original extensions of various types of sensitive data. This version appeared in the middle of March, 2023. In fact, technically it is STOP Ransomware, that uses AES encryption algorithms to encrypt user’s files. This suffix is one of the hundreds of different extensions used by this malware. Does it mean you lost your valuable data? Not necessarily. There are certain methods, that allow you to recover your files fully or partially. Also, there is free decryption utility called STOP Djvu Decryptor from EmsiSoft, that is constantly updated and is able to decrypt hundreds of types of this virus. After finishing its disastrous activity Qazx Ransomware creates _readme.txt file (ransom note), where it informs users about the fact of encryption, amount of ransom, and payment conditions:

The authors of the virus report that the victim’s files are encrypted and the only way to decrypt them is to buy a key and a decryptor, that is, to pay a ransom. Attackers demand $980, if the victim agrees to pay the ransom within 72 hours, then the ransom is reduced to $490. Criminals offer to decrypt one file for free and thus confirm that it is possible that the victim can return all his files. Of course, successful decryption of one file does not guarantee that after the ransom is paid in full, the victim will receive a key and a decryptor. We strongly recommend removing the STOP virus, using special anti-malware programs. Before proceeding with this, you need to know that when you start deleting a virus and attempting to independently recover files, you block the ability to decrypt files by paying the authors of the virus the amount they requested. After complete removal, you can try STOP Djvu Decryptor from EmsiSoft, the most comprehensive utility to decrypt files, encrypted by Qazx Ransomware. All standard Windows features to restore files are worth trying, although the threat technically reduces the prospects of a successful outcome. The final step is using file-recovery software. The experience shows, that this can be a workaround, that helps to return the information at least partially. Stellar Data Recovery Professional is one of the best file-recovery tools and, if used properly, may recover copies and duplicates of encrypted files, that were removed prior to infection. The only option for a successful 100% recovery is using existing backups. Read this tutorial to remove Qazx Ransomware and decrypt .qazx files for free in Windows 11, 10, 8, 7.

How Qazx Ransomware infected your computer

Qazx Ransomware, as subversion of STOP/Djvu Ransomware, is typically spread through spam email campaigns, malicious software downloads, fake software updates, and exploit kits. Here are some of the most common ways that the ransomware can infect computers:

  • Spam email campaigns: The attackers may use email messages that appear to be legitimate, such as invoices, job offers, or shipping notifications, to trick the recipients into downloading an infected attachment or clicking on a malicious link.
  • Malicious software downloads: The attackers may distribute the ransomware through fake software downloads or updates on various websites, including torrent and file-sharing sites.
  • Fake software updates: The attackers may use pop-ups or other notifications that claim to be software updates or security patches, but are actually designed to trick users into downloading the ransomware.
  • Exploit kits: The attackers may use exploit kits, which are software tools that identify and exploit vulnerabilities in computer systems, to deliver the ransomware.

Once the ransomware infects a computer, it will encrypt the files on the system and demand a ransom payment in exchange for the decryption key. It is important to note that paying the ransom does not guarantee that the attackers will provide the decryption key or that the files will be restored, so it is always best to avoid becoming infected in the first place by practicing safe browsing habits and keeping software up to date with the latest security patches.
