QUAL Ransomware Virus: How It Works & What To Do If Infected
Written by: Stelian Pilici
Published on:
Ransomware attacks have been on the rise, inflicting damage and extorting money from victims globally. The latest emerging threat is a new variant called QUAL ransomware. This insidious cyberattack encrypts personal files on infected devices and restricts access until a ransom is paid.
This comprehensive guide will provide an in-depth look at QUAL ransomware, how it works, detection signs, and most importantly, what you can do if you become a victim. With the right preventative measures and recovery steps, the impact of this virus can be minimized.
This article contains:
Overview of QUAL Ransomware
QUAL ransomware is the newest version of the notorious STOP/DJVU ransomware family. It uses robust encryption algorithms to lock files and appends the .QUAL extension to encrypted filenames. Once infected, victims cannot open their files, including documents, images, videos, and more.
The ransomware then displays a ransom note named _readme.txt with payment instructions. It demands payment in Bitcoin cryptocurrency to allegedly send a decryption key for restoring file access. If users see the .QUAL extension added to inaccessible files, it signifies an active infection.
QUAL joins the ranks of the most harmful ransomware threats. It can lead to permanent data loss if proper precautions are not exercised. Understanding how it spreads, encrypts, and demands payment is crucial to protect yourself.
Infection Vectors
QUAL ransomware uses various infection mediums to compromise devices:
Once executed on a system, the ransomware runs a scan searching for specific file types like documents, images, videos, and more.
Encryption Process
During the encryption phase, QUAL ransomware targets and encrypts selected file types using a symmetric AES algorithm. A unique encryption key is generated to lock each file.
The original files are deleted, leaving only encrypted versions with the .QUAL extension appended. This prevents any program from opening them, essentially holding your data hostage.
Ransom Demands
With files encrypted, QUAL displays a _readme.txt ransom note with payment instructions:
Contact the developers at support@fishmail.top and datarestorehelp@airmail.cc
Visit the payment website to purchase a decryptor tool
Pay the ransom in Bitcoin cryptocurrency
Ransom starts at $490 worth of Bitcoin and increases to $980 if not paid promptly
The note claims only they can provide the decryption key to restore data access. But even paying does not guarantee file recovery.
This is the ransom note that the QUAL ransomware will show to its victims:
ATTENTION!
Don’t worry, you can return all your files! All your files like pictures, databases, documents and other important are encrypted with strongest encryption and unique key. The only method of recovering files is to purchase decrypt tool and unique key for you. This software will decrypt all your encrypted files. What guarantees you have?

Here is a summary of the QUAL ransomware:
Ransomware family: STOP/DJVU ransomware
Extensions: .QUAL
Ransomware note: _readme.txt
Ransom: From $490 to $980 (in Bitcoins)
Contact: support@fishmail.top and datarestorehelp@airmail.cc emails
Symptoms: The images, videos, and other documents have the “.QUAL” extension and cannot be opened by any programs
File recovery: Unfortunately, it is not currently possible to decrypt the files encrypted by the QUAL ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can decrypt them in the future.
How QUAL Ransomware Works
Now let’s explore the step-by-step process of how a QUAL ransomware attack unfolds:
1. Initial Compromise
An infection begins by compromising a vulnerable system through an infected email attachment, malicious ad, compromised site, or other vector. Once clicked or accessed, the malicious payload secretly downloads.
2. Malware Execution
The malware payload then executes on the system, initiating the QUAL ransomware infection. It utilizes evasion techniques to avoid detection by antivirus software.
3. Environment Reconnaissance
QUAL scans the infected system’s environment, gathering information like the operating system version, system language, computer name, and more.
4. Internal Network Propagation (Optional)
If connected to a larger network, QUAL may attempt to spread laterally to infect more devices and servers. It leverages techniques like SMB exploitation.
5. Targeted Encryption
QUAL initiates an encryption loop, scanning for and encrypting high-value files like documents, images, videos, databases, and source code. Each file is encrypted with a unique key.
6. Appending New Extension
The original files are deleted after encryption. The encrypted versions receive the .QUAL extension appended to the filenames.
7. Ransom Note Deployment
The ransomware drops _readme.txt containing payment instructions to allegedly decrypt files by purchasing a tool from the attackers.
8. Persistence Mechanisms
To maintain access, QUAL deploys persistence techniques like creating registry run keys and scheduled tasks to execute on system reboots.
9. Command & Control Communication
Finally, QUAL contacts the command & control servers operated by the threat actors to report a successful infection and transmit data.
This multi-stage attack chain allows QUAL to infiltrate systems, encrypt data, and demand ransom payments. Understanding how it works can help equip you with defenses.
What To Do If You Are Infected
Falling victim to QUAL can be devastating but do not panic. There are steps you can take to handle the infection and work to recover files. Here are tips if your system is compromised:
1. Isolate the Infected Device
Disconnect the infected computer from any networks or external devices immediately. This prevents further spreading of the ransomware.
2. Take Photos of the Ransom Note
Photograph any ransom notes or payment instructions that appear. Save this evidence in case it disappears during deeper analysis.
3. Check for Encrypted Files
Search for file types like DOC, JPG, PDF that now have the .QUAL extension. This confirms the presence of file encryption.
4. Report the Crime
Contact law enforcement and cybersecurity authorities to report the ransomware attack. Provide any evidence like the ransom note.
5. Seek Help from IT Security Firms
Engage IT security firms that specialize in ransomware attacks. They may assist with remediation and file recovery efforts.
6. Avoid Paying the Ransom
As difficult as it may be, avoid paying the ransom. There are no guarantees you will get decryption keys or file access.
7. Restore from Backups
Check if clean file backups exist that can restore your data. Ensure backups are disconnected from infected systems first.
8. Use Shadow Volume/System Restore
If available, leverage Shadow Volume copies or System Restore to recover previous versions of encrypted files.
9. Reset Passwords and Accounts
Once your system is clean, reset all account passwords and credentials to prevent further misuse.
10. Monitor Accounts and Credit
Keep close watch on accounts and financial statements for any fraudulent activity following an infection.
While QUAL’s encryption is robust, taking prompt action gives you the best chance of recovering your data. Be ready with contingency plans in case of infection.
Remove the QUAL ransomware and recover the files
It’s important to understand that by starting the removal process you risk losing your files, as we cannot guarantee that you will be able to recover them. Your files may be permanently compromised when trying to remove this infection or trying to recover the encrypted documents. We cannot be held responsible for losing your files or documents during this removal process.

How to Stay Safe Online
Here are 10 basic security tips to help you avoid malware and protect your device:
Use a good antivirus and keep it up-to-date.
It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.
Keep software and operating systems up-to-date.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.
Be careful when installing programs and apps.
Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."
Install an ad blocker.
Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.
Be careful what you download.
A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.
Be alert for people trying to trick you.
Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.
Back up your data.
Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.
Choose strong passwords.
Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.
Be careful where you click.
Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.
Don't use pirated software.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
