QEPI Ransomware Virus: How It Works & What To Do If Infected
Written by: Stelian
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 QEPI 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 QEPI 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.
Overview of QEPI Ransomware
QEPI ransomware is the newest version of the notorious STOP/DJVU ransomware family. It uses robust encryption algorithms to lock files and appends the .QEPI 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 .QEPI extension added to inaccessible files, it signifies an active infection.
QEPI 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
QEPI 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, QEPI 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 .QEPI extension appended. This prevents any program from opening them, essentially holding your data hostage.
Ransom Demands
With files encrypted, QEPI 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 QEPI 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 QEPI ransomware:
Ransomware family: STOP/DJVU ransomware
Extensions: .QEPI
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 “.QEPI” extension and cannot be opened by any programs
File recovery: Unfortunately, it is not currently possible to decrypt the files encrypted by the QEPI 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 QEPI Ransomware Works
Now let’s explore the step-by-step process of how a QEPI 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 QEPI ransomware infection. It utilizes evasion techniques to avoid detection by antivirus software.
3. Environment Reconnaissance
QEPI 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, QEPI may attempt to spread laterally to infect more devices and servers. It leverages techniques like SMB exploitation.
5. Targeted Encryption
QEPI 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 .QEPI 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, QEPI deploys persistence techniques like creating registry run keys and scheduled tasks to execute on system reboots.
9. Command & Control Communication
Finally, QEPI contacts the command & control servers operated by the threat actors to report a successful infection and transmit data.
This multi-stage attack chain allows QEPI 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 QEPI 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 .QEPI 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 QEPI’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 QEPI 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.
It’s recommended to create a backup image of the encrypted drives or files before proceeding with the malware removal instructions so that you can restore them if the decryption keys are recovered from the cybercriminals’ servers.

10 Rules to Avoid Online Scams
Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
