What Is Mppn Virus?
MPPN is a ransomware infection that belongs to the STOP/DJVU ransomware family. Once your computer has been affected, the Mppn ransomware will encrypt all your files and append the .mppn extension to their file names.
The sole purpose of file encryption is demanding a ransom payment for their restoration via a unique decryption key that only the ransomware operators possess. However, there is no guarantee that you will receive such a key, if you pay the demanded ransom. That is why t is advisable not to trust cybercriminals and proceed with the removal of the ransomware and the recovery of your system via alternative ways.
Can Mppn Files Be Decrypted?
Unfortunately, if your files have been encrypted by Mppn ransomware, it most probably means that the battle is lost. The chances to get your files restored on your own or with the help of a company/a professional that advertises decryption capabilities are nearly non-existent.
What most such companies and professionals do is buy a decryption tool from the ransomware operators, and add a markup to the ransom amount upon charging you for their decryption services. In other words, trusting anyone, other than an officially released decrypter, with the decryption of your files is utterly pointless.
We will update this article once we have more information on possible decryption, even though the chances are quite slim. What you should do for now is remove the ransomware from your system, so that it doesn’t reinfect you and it doesn’t spread further. Continue reading to get to the final part of the article where we provide technical removal instructions.

What Are .mppn Files
The .mppn files are encrypted copies of your original data, using AES encryption algorithm. This means that the only way to fix the files is via a decryption key, which can be two types – online and off-line. What the virus does is it scans for the following kinds of files, based on their file extensions and changes their data with the encryption algorithm:
- Archive file formats (.zip, .rar, etc).
- Documents of different types (.docx, .pptx, etc.).
- Audio (.mp3, .wav, etc.).
- Picture file kinds (.jpg, .png, .etc).
- Videos (.mp4, .avi, etc.).
- Others.
The outcome of this encryption process is that the files may assume the following appearance:

The proper way to get a program off your computer is to Uninstall it. To do that:
Step 3: Clean any registries, created by Mppn on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Mppn there. This can happen by following the steps underneath:
