What is Mpag virus?
Mpag virus is a new ransomware that attacks the victim’s computer by encrypting files and demanding a ransom for decrypting them. The ransomware attack can lead to data loss and financial losses. Mpag encrypts files, renames them by appending the .mpag extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “document.docx” will be renamed to “document.docx.mpag”, a “image.jpg” file to “image.jpg.mpag”, “invoice.pdf” to “invoice.pdf.mpag”, and so on.

Mpag ransomware is a new malware, the latest variant of STOP (djvu) ransomware. Like other variants, it encrypts all files on the computer and then demands a ransom for decryption. Mpag encrypts files using a strong encryption method, which eliminates the possibility of finding a key in any way. For each victim, it uses a unique key with a small exception. If the ransomware cannot establish a connection with its command and control server (C&C) before starting the encryption process, then it uses an offline key. This key is the same for different victims, which makes it possible in some cases to decrypt files that were encrypted during the ransomware attack.
Mpag ransomware has the ability to encrypt files of any type, regardless of what is in them. But it skips files with the extension: .ini, .dll, .lnk, .bat, .sys and files named ‘_readme.txt’. Thus, the following common file types can be easily encrypted:
.bkp, .csv, .ppt, .ibank, .apk, .wpe, .sr2, .xmind, .z3d, .esm, .eps, .orf, .dxg, .forge, .xlsx, .cer, .fsh, .zif, .xlsx, .y, .wsh, .wotreplay, .pst, .wsc, .icxs, .bkf, .vcf, .raf, .rgss3a, .doc, .dmp, .ff, .css, .bc6, .dcr, .wm, .das, .zip, .mlx, .xls, .desc, .tor, .wmd, .dazip, .itdb, .bsa, .wdp, .zdc, .webp, .xll, .wsd, .pptx, .mcmeta, .wgz, .wmv, .wp7, .wpb, .rw2, .fos, .m2, .js, .gdb, .d3dbsp, .wbk, .ybk, .kf, .ltx, .xwp, .wn, .snx, .pdf, .3fr, .sav, .sb, .accdb, .mdbackup, .xml, .gho, .pptm, .sid, .hplg, .wma, .avi, .indd, .x, .wpl, .dbf, .xar, .zdb, .ncf, .arw, .cas, .lrf, .vdf, .erf, .qdf, .zabw, .wbm, .xbplate, .rofl, .3dm, .zi, .srf, .hvpl, .pem, .ysp, .t12, .yml, .xmmap, .arch00, .png, .mrwref, .wpd, .qic, .crt, .odt, .z, .bay, .wp5, .wmo, .xlk, .r3d, .wbz, .rar, .xyp, .rwl, .rtf, .bc7, .wp4, .jpeg, .ptx, .pkpass, .xy3, .x3f, .re4, .1, .tax, .t13, .flv, .wpg, .iwi, .wcf, .xx, .wma, .big, .lvl, .rim, .pef, .yal, .sidd, .w3x, .x3d, .fpk, .wpd, .itl, .wri, .zw, .pak, .map, .vpp_pc, .xlsm, .xf, .p7b, .wpw, .crw, .mdb, .wbmp, .jpg, .sidn, .bar, .dba, .sql, .txt, .dng, .py, .0, .xbdoc, .sie, .ws, .wb2, .cr2, .xdl, .wpt, .xld, .xls, .7z, .upk, .kdc, .ztmp, .syncdb, .slm, .pfx, .1st, .cfr, .xpm, .sis, .mp4, .m3u, .p12, .odc, .wp6, .itm, .xdb, .2bp, wallet, .menu, .ods, .odm, .vfs0, .wp, .wmv, .srw, .wire, .odp, .mov, .raw, .wbd, .mdf, .wps, .wps, .ai, .xlsb, .hkx, .wmf, .x3f, .psd, .mef, .svg, .bik, .wdb, .psk, .pdd, .zip, .mddata, .ntl, .xlgc, .wpa, .p7c, .der, .kdb
Each file that has been encrypted will be renamed. This means the following. If a file was called ‘document.docx’, then after encryption, it will be named ‘document.docx.mpag’. Mpag ransomware can encrypt files located on all drives connected to the computer. Therefore, files located in network attached storage and external devices can also be encrypted. It encrypts file by file, when all the files in the directory are encrypted, it drops a new file in the directory, which is called ‘_readme.txt’. Below is the contents of this file.
All directories with encrypted files have this file. But the contents of this file are the same everywhere. This file contains a message from Mpag creators. In this message, the criminals report that all the files were encrypted and the only way to decrypt them is to buy a decryptor and key. Attackers demand a ransom of $490, if the victim does not pay the ransom within 72 hours, then the ransom will double to $980. Mpag authors left two email addresses that the victim must use to contact them. To confirm the possibility of decryption, criminals offer to decrypt one file that does not contain important information for free. But it’s obvious that there is no guarantee that even by paying the ransom, the victim will be able to decrypt all files that have been encrypted.
Text presented in the Mpag ransom note:
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.

|Decryption||Mpag File Decrypt Tool|
Mpag authors claim that it is impossible to decrypt files that have been encrypted. Unfortunately, this is true. Security researchers confirm that a key and a decryptor are required to decrypt files. As we said above, in some cases, the Mpag ransomware encrypts files with an offline key that can be determined by security researchers. Files encrypted with this key can be decrypted using a free Mpag File Decrypt Tool. In all remaining cases, decryption is not yet possible. But there are several alternative ways that can allow everyone to recover the contents of encrypted files.
How to remove Mpag ransomware virus
Before you start decrypting or recovering .mpag files, you need to remove Mpag ransomware and its autostart entries. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection. Read this entire manual, then open it on your smartphone or print it. So it will be more convenient for you to carry out all the necessary actions.
It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Mpag ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Mpag virus, then let us know in the comments, we will try to help you.
To remove Mpag ransomware, follow the steps below:
Kill Mpag virus
Press CTRL, ALT, DEL keys together.
Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Mpag virus then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.
It is not difficult to detect a process related to the Mpag ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Mpag ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.
Disable Mpag start-up
Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.
Close Task Manager.
Delete Mpag task
Type “Task Scheduler” in the search bar. Click Task Scheduler app in the search results. Click “Task Scheduler Library” in the left panel. On the right panel, right-click to “Time Trigger Task” and select Delete.
Close Task Scheduler.
Remove Mpag virus
Run Task Manager and select the “Start-Up” tab. Right click to the Mpag Start-Up entry and select Open File Location as shown below.
A directory containing one file will open in front of you, this file is the Mpag virus. It needs to be removed. If you try to delete it immediately, then you will not succeed, since this file is protected from deletion.
To delete this file, you need to do the following. Right-click on the file, select Properties. In the window that opens, select Security tab. Next, click the Advanced button below. A window will open as shown in the following example.
Click Disable inheritance. In the Block inheritance dialog box that opens, select the first item (Convert inherited permissions…) as shown below.
In the Permission entries list, select “Deny Everyone”, click Remove button and then OK. Close the file properties window. You should now be able to remove the Mpag virus. Right-click on the file and select Delete.

How to decrypt .mpag files
All files with the ‘.mpag’ extension are encrypted. Their contents cannot be unlocked simply by removing this extension or completely changing the filename. To decrypt .mpag files, you need a Mpag File Decrypt Tool. Fortunately, Emsisoft has created a free decryptor called STOP Djvu decryptor.
To decrypt .mpag files, use free Mpag File Decrypt Tool
- Download Mpag File Decrypt Tool from the following link.
STOP Djvu decryptor
- Scroll down to ‘New Djvu ransomware’ section.
- Click the download link and save the ‘decrypt_STOPDjvu.exe’ file to your desktop.
- Run decrypt_STOPDjvu.exe, read the license terms and instructions.
- On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
- Click the ‘Decrypt’ button.
Mpag File Decrypt Tool is a free tool that allows everyone to decrypt .mpag files for free. At the moment, the decryptor can only decrypt files that have been encrypted with an offline key. Unfortunately, if the files were encrypted with an online key, then the free decryptor is completely useless. The online key is unique to each infected computer, and at the moment there is no way to find this key. Of course, criminals have this key, but we do not think that paying a ransom is a way to decrypt .mpag files. In the case when the files are encrypted with an online key, there is a chance to restore the encrypted files using alternative methods, which are described below.
How to find out which key was used to encrypt files
Since Mpag File Decrypt Tool only decrypts files encrypted with the offline key, each Mpag’s victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them. We recommend using the second method, as it is more accurate.
Find out the type of key using ‘_readme.txt’ file
- Open the ransom demand message (‘_readme.txt’ file).
- Scroll down to the end of the file.
- There you will see a line with the text ‘Your personal ID’.
- Below is a line of characters that starts with ‘0438’ – this is your personal id.
Find out the type of key using ‘PersonalID.txt’ file
- Open disk C.
- Open directory ‘SystemID’.
- Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the Mpag ransomware used to encrypt files.
The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, the Mpag ransomware used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.
Mpag File Decrypt Tool : “No key for New Variant online ID”
If, when you try to decrypt .mpag files, Mpag File Decrypt Tool reports:
No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible
It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the mpag authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.
Mpag File Decrypt Tool : “No key for New Variant offline ID”
If, during decryption of .mpag files, Mpag File Decrypt Tool reports:
No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.
It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data.
If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .mpag files.
This video step-by-step guide will demonstrate How to remove Mpag virus, Decrypt/Recover .mpag files.
How to restore .mpag files
As we already said, Mpag File Decypt Tool can only decrypt files encrypted using the so called ‘offline key’. What to do when files were encrypted with an online key? Even in this case, everyone has a chance to recover the contents of encrypted files. This is possible due to the existence of several alternative ways to restore files. Each of these methods does not require a decryptor and a unique key, which is in the hands of criminals. The only thing we strongly recommend that you perform (if you have not already done so) is to perform a full scan of the computer. You must be 100% sure that Mpag virus has been removed. To find and remove ransomware, use the free malware removal tools.
Restore .mpag files using Shadow Explorer
The Windows OS (10, 8, 7 , Vista) has one very useful feature, it makes copies of all files that have been modified or deleted. This is done so that the user can recover, if necessary, the previous version of accidentally deleted or damaged files. These copies of the files are called ‘Shadow copies’. One tool that can help you recover files from the Shadow copies is ShadowExplorer. It is very small tool and easy to use. Unfortunately, ransomware often delete Shadow copies, thus blocking this method of recovering encrypted files. Nevertheless, be sure to try this method.
ShadowExplorer can be downloaded from the following link. Save it to your Desktop.
