How Mpal ransomware behaves
From our report of May 2020 · not reviewed since
The cleaning process starts with Mpal ransomware termination
You may need to gather some help for the best results of Mpal ransomware removal because this threat can affect much more than your personal files stored on the computer.
When the threat interferes with parts of the system and disables or even damages functions, you need to take care of that damage before you proceed with data recovery.
Also, you need to remove Mpal ransomware completely from the system before you can restore those encrypted files or add copies of them from the backup. Ransomware can possibly run the second wave of encryption and damage those newly added documents or images causing permanent damage of files and even money if you paid for the possible decryption.
Mpal ransomware virus can be cleared once you deleted and terminated the malware using or . These security tools or any anti-malware program that detects the intruder can perform the removal for you and clean all the repeated files or programs. Remember to restore parts of the machine using PC repair or optimization software like before you try to restore encoded files yourself.
[GI=method-1]Remove Mpal ransomware from the system using the AV tool by rebooting the machine in Safe Mode with Networking first
[GI=method-2]You may try the System Restore feature for the cleaning purpose because this method allows resetting the machine in a previous state
Windows Previous Versions is the technique that helps with file recovery after ransomware infections
When the System Restore feature gets enabled, you can rely on Windows Previous Versions and restore files affected by Mpal ransomware
ShadowExplorer - the method for file restoring
When Shadow Volume Copies are left untouched, you can possibly rely on ShadowExplorer and restore Mpal ransomware encrypted data

When Mpal ransomware uses older versions of codes and relies on simpler techniques, you can possibly decrypt data using this DJVU decryption tool
From our report of May 2020 · not reviewed since
Malware spreading methods involving online services and legitimate names of companies
Ransomware typically is delivered via emails since attachments can be injected with malicious macros and scripts leading to direct payload download.
Such emails trick people into opening the notification with names of shopping sites, or companies like DHL, FedEx, and so on. Those emails claim about financial information and orders or invoices, so people open documents and enable the content without notice.
Another, more common method that allows malware creators to attack victims - malicious files in particular packages and cheats or cracks. When torrent services offer such activities as getting cheatcodes for video games or cracks for legitimate software, licensed versions, there are many files that get installed. Many people cannot even notice that some executables or other types of data got added, but ransomware is loaded.
You need to pay attention to services, sources you rely on, and be more suspicious about the content you get exposed to and received emails, even though notifications seem legitimate and real.

Mpal ransomware is a highly dangerous virus encrypting your personal files for ransom
Mpal ransomware - the cryptovirus that adds .mpal extension to affected data and then displays the message with an offer to decrypt files after the cryptocurrency payment is made.
Criminals that develop this virus and other versions of Djvu ransomware prefer Bitcoin cryptocurrency. Also, this family is known for releasing new versions constantly. This is achieved because not many things get changed in the coding, and other features like ransom note file _readme.txt or contact emails remain the same for a while.
Even though Mpal ransomware virus is the first one that came out in May 2020, it is the 223rd in this ransomware family in general. This is a threat that researchers know about and try to monitor as much as possible because of the current activity status of these campaigns and attacks.
Unfortunately, the family was decryptable for a while before, but not anymore because previously useable STOPDecrypter is no longer supported. Malware creators changed the coding and methods of encryption, key generation, so experts cannot offer easy decryption procedures as before. However, some of the victims can get their files recovered with the help of the Emsisofts Djvu decrypted tool.
One thing though, this tool only works for versions that use offline keys. You can determine if the key used in your case is offline or not by checking the ID in the ransom note. If it ends in t1 it is most likely offline-based.
Other versions of the DJVU and STOP ransomware now mostly use an online key generation method that allows forming a unique identification number for each affected device and victim. However, it means that malware makes the connection to a remote server each time it generates this ID, and it is needed for decryption processes too, so victims need to contact criminals to get the tool and the particular decryption key.
Any communication is not safe because malware creators may have different purposes and damage your device further or ask for a bigger amount than the ransom note initially states. More on decryption alternatives below the article.
Mpal ransomware is focusing on file encryption because when the access to images, documents, or archives is blocked, the user may be more eager to pay the demanded amount of cryptocurrency. Criminals promise to recover those files after the money transfer, but there is a possibility that actors can damage your machine after that.
Once the ransom note appears on the screen, you can be sure that Mpal ransomware is done with the encryption process. This happens pretty quick, and in most cases, the victim cannot notice anything suspicious. Djvu versions tend to display the Windows Update window or another fake process indication, so the slowness of the machine is not creating suspicions.
The main payload file of the virus can get dropped in advanced, way before you notice the encryption or other symptoms of Mpal ransomware, so many changes that already get made in the background can affect the performance and cleaning or file recovery processes.
The ransom note _readme.txt is placed on the machine as a final stage of the attack because once all the changes get made, the only thing left is to receive payments from victims:
You need to react to this attack and clear the machine from malware as soon as you receive the money-demanding message. You can remove Mpal ransomware with anti-malware tools, and the sooner you try to do so the better.
Ransomware sometimes can delete the main payload after the encryption process is done, but you need to remove all the files related to the intruder before you even try to restore files or add anything new on the computer.
Mpal ransomware in addition to file encryption can load trojans that steal malware or run separate scripts that focus on data extraction. There are many details that can be valuable and useful for criminals because there are new tactics of ransomware creators. They focus on getting some sensitive information from people or companies, so non-paying victims can be blackmailed after that.
These facts about additional malware and changes that threat does besides encryption affect the Mpal ransomware removal significantly because it keeps AV tools, security features, and programs disabled, avoids detection. You may need to enter the Safe Mode before you can run the anti-malware tool properly, but such a method is the best way to get rid of the malware of this type.
Unfortunately, antivirus programs are not capable of recovering encoded files for you, so you need to rely on different methods for the recovery of your damaged data. Mpal ransomware is a powerful virus, so your options are narrow:
Your machine should be double-checked before moving on with any of these methods, so the threat is completely terminated, and all you have to do is clear Mpal ransomware virus damage with something like and repair files corrupted ins system folders. Then you can rely on the more trustworthy method and replace files affected by the virus with safe copies or try to recover encoded ones.

- data backups stored on the cloud or external device;
- third-party tools designed to restore files;

How to remove Mpal ransomware
Tools you'll need
All of these are free except where noted. Download them on a clean device if the infected PC is offline.
- A USB stick: to keep the ransom note, two or three encrypted files and screenshots off the infected PC.
- Microsoft Defender Offline: built into Windows 11 and Windows 10; scans before Windows starts, so running malware cannot hide.
- Microsoft Safety Scanner: a second, portable scanner with current signatures; each download works for 10 days.
- ID Ransomware: identifies the family from the note and one encrypted file and says whether a decryptor exists.
- No More Ransom: the free decryptors from police and security companies; check it again every few months.
- Fortect (optional): scans Windows for malware and repairs the system files and settings it damaged. The free scan is in the box above.
How to remove Mpal ransomware and get your files back
Work in this order.
Disconnecting comes first, removal comes before any restore, and nothing here asks you to contact the attackers.
Step 1: Disconnect the PC and unplug backup drives
Unplug the network cable or turn off Wi-Fi, and disconnect USB drives, external disks and network shares, so Mpal ransomware cannot reach more files. Pause OneDrive, Google Drive or Dropbox sync, because synced folders upload the encrypted copies over the good ones.
Leave the PC on but offline while you read the next steps, since a restart can let the ransomware run again. This applies to Windows 11 and Windows 10 alike.

Step 2: Save the ransom note and confirm the family
Your files now end in
.mpaland the instructions are in_readme.txt. Save both to a USB stick, a copy of the note and two small encrypted files, before anything else.On another device, check them with ID Ransomware or Crypto Sheriff: the family name decides which decryptor, if any, can help. Keep the note's ID and contact line for your report.

Windows 11: the ransom note and encrypted files to copy for identification. Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 3: Check for a free decryptor
Our last check found that for Mpal ransomware, no free decryptor is known (checked 6 October 2026). Look again yourself in the No More Ransom list and the free decryptor pages of Emsisoft, Avast and Kaspersky, which add new families every year.
A decryptor needs the ransomware gone first, or it encrypts the files again. Keep at least one copy of the encrypted files on an external drive, even if no tool works yet.

Step 4: Remove the ransomware before you restore or decrypt
Removing Mpal ransomware does not bring the files back, but it has to come first. Start with Defender's Full scan, then the offline scan from the same Scan options page, which checks the disk before Windows loads.
If the scan cannot start, use Safe Mode with Networking. Delete the ransom notes only after you have saved a copy, because removal tools sometimes leave them behind on Windows 11 and Windows 10.

Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 5: Look for shadow copies of the files
Windows keeps shadow copies for restore points and backups, and some ransomware fails to delete them.
vssadmin list shadowsin an administrator Command Prompt tells you at once whether any exist.If they do, right-click the folder that held your files, open Properties > Previous Versions, select a version from before the attack, and click Open to check it before you Restore or copy the files out. Windows 11 and Windows 10 both have the tab.

Windows 11: vssadmin list shadows shows whether shadow copies exist. Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 6: Restore the files from a backup or recover deleted originals
A backup made before the attack is the surest way back. Connect it only once the PC is clean, then restore from File History, Windows Backup, OneDrive's Restore your OneDrive or your own external copies.
Without a backup, try file recovery: the originals that Mpal ransomware deleted may still be on the disk until something overwrites them. Install nothing new on the drive you want to recover from on the Windows 11 or Windows 10 PC.

Manual removal using Safe Mode
Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. - it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.

Windows 10 / Windows 8
- Right-click on Start button and select Settings.

- Scroll down to pick Update & Security.

- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.

- Select Troubleshoot.
- Go to Advanced options.

- Select Startup Settings.

- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.

Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.

- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.

- Go back to the process, right-click and pick End Task.

- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.

Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.

- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
Downloads
Recycle Bin
Temporary files - Pick Clean up system files.

- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
%AppData%
%LocalAppData%
%ProgramData%
%WinDir%
After you are finished, reboot the PC in normal mode.
Report it and recover your files
Report it
Report the attack even if you do not expect the files back: insurers and banks ask for the report number, and police use the contacts in the note to link cases.
- United States
- FBI IC3 · FTC ReportFraud
- United Kingdom
- Report Fraud (formerly Action Fraud) · NCSC
- Australia
- ReportCyber (ASD)
- EU countries
- Europol: national reporting sites
Give the victim ID, the note and the date the files were encrypted. A business that holds personal data may also have to notify its data protection authority, in the EU within 72 hours.
Backups: the 3-2-1 rule
Keep three copies of files that matter, on two kinds of storage, with one copy offline or off-site.
A disk that stays plugged in is reached by malware like Mpal ransomware together with the PC; one you connect only for the backup is not.
On Windows 11, File History keeps versions on an external drive, and OneDrive keeps earlier versions of synced files. Before restoring anything, make sure the PC no longer shows files that end in .mpal and no longer open.
Setting it up step by step: 3-2-1 backups on Windows 11 and 10.
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity.
While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important - recover your lost files
Ransomware is one of the biggest threats to personal data.
Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as can also be effective and restore at least some of your lost data.
Questions about Mpal ransomware
How do I open .mpal files?
You cannot open them by renaming or with another program, because the content of files ending in .mpal has been encrypted. The only ways back are a working decryptor for the family, or clean copies from elsewhere:
- OneDrive versions
- File History
- an offline backup drive
- Previous Versions if the ransomware did not delete them
Identify the family first by uploading the ransom note and one encrypted file to ID Ransomware or No More Ransom. Avoid websites and programs that promise to open any encrypted file; they do not work and some are scams.
Is there a free Mpal ransomware decryptor?
We last checked on 6 October 2026, and for Mpal ransomware no free decryptor is known. We check No More Ransom, which collects free tools from police and security companies, and the decryptor pages of the major antivirus vendors. A working decryptor exists only when the encryption has a flaw or the keys were leaked or seized.
Ignore sites and videos that offer a "Mpal ransomware decryptor" for download or for a fee: these are usually scams or malware. Real decryptors are free and come from known security companies or law enforcement. Keep the encrypted files in case a tool appears later.
Did Mpal ransomware steal my files or passwords?
We do not know yet. Nothing published so far shows data theft by Mpal ransomware, but the only confirmed sign is files that end in .mpal and no longer open, which says nothing about what happened before. Many current ransomware attacks copy files or run a password stealer first, so it is wise to act as if they did.
From a clean device, change the passwords that were saved in the browsers on this PC, starting with e-mail and banking, sign out of all sessions and turn on two-step verification. Watch bank statements and account activity for the next few weeks.
Should I pay the ransom?
We advise against it, and so do the FBI, Europol and national cyber agencies. Payment does not guarantee a working tool: some attackers never reply, some tools damage files, and some variants have no decryptor at all. Paying also funds further attacks and can make you a target again.
Before considering payment, try every recovery option in this guide and report the attack. Companies must involve their legal adviser and insurer, because payments to sanctioned groups can be illegal. If files are truly irreplaceable, store the encrypted copies and wait; decryptors sometimes appear later.
Can a data-recovery company decrypt my files for a fee?
Only if a decryptor already exists or the company pays the attackers for you. Some "ransomware recovery" services advertise that they can decrypt families with no known flaw; in practice they negotiate with the attackers and add their own fee. Others use the same free tools listed on No More Ransom.
Before you hire anyone, ask in writing how they will recover the files, whether they will contact the attackers and what happens if they fail. A legitimate service answers clearly. If a free decryptor exists for your family, you can run it yourself.
How did Mpal ransomware get on my computer?
The way Mpal ransomware spreads has not been documented yet, so look at your own recent activity. On home PCs, ransomware most often comes with cracked programs, game cheats, key generators and fake updates, or with an e-mail attachment that was opened. On business networks, attackers usually log in through Remote Desktop with a stolen or guessed password.
Think back to what was downloaded or installed in the days before files that end in .mpal and no longer open, and check the Downloads folder and Installed apps sorted by date. Keep anything suspicious for your report, but do not run it again.
Is Mpal ransomware the same as other ransomware with a similar name?
Not necessarily. Ransomware names come from the file extension, the note or a word in the code, so unrelated families often end up with similar names, and one family can appear under several names. The difference matters: a decryptor or advice for one family does not fit another and can damage files.
Compare the ending added to your files and the exact name of the note with the summary table at the top of this guide, then upload the note and one encrypted file to ID Ransomware from a clean device. If the result names another family, follow the guide for that family instead.
Can I delete _readme.txt?
Yes, the note itself is harmless text and deleting it does not affect your files. Keep at least one copy first, outside the infected PC. _readme.txt contains your personal ID and the attackers' contact details, which identification services use to tell which family encrypted your files, and which a decryptor may need later.
Police reports also ask for it. Once you have saved a copy, you can remove the notes from every folder after the ransomware program has been removed and your files are restored or backed up.
Should I reinstall Windows after the .mpal attack?
Reinstalling removes the ransomware but not the encryption: your files ending in .mpal stay encrypted afterwards. So first copy the encrypted files and the ransom note to a separate drive, in case a decryptor appears later. Then decide:
- a clean-up with an offline scan is often enough for home PCs
- while a full reset is safer if remote access was involved
- scans keep finding new items
Restore your backups only after the PC is clean, and change passwords from another device.
Will Fortect remove Mpal ransomware?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Mpal ransomware, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
