What is “Nppp”?

Nppp can be correctly identify as a ransomware-type infection.

Nppp is similar to other representatives of the same family: Mool, Ooss, Mmnn. It crypted all popular file types. Nppp adds its own “.nppp” extension into all files. For example, the file “video.avi”, will be changed into “video.avi.nppp”. Hence, users cannot use the your documents, and gets a simple text file on his desktop, in which ransomware distributors offering to pay for the decrypting. As soon as the encryption is successfully accomplished, as mentioned, Nppp creates a special file _readme.txt and puts it into all folders that contain the modified files.

Here is a info for the Nppp infection:

This text asking payment is for get files back via decryption key:

The alert demanding from users to pay the ransomware to decrypt the encoded data contains these frustrating warnings

The cryptography algorithm used by Nppp is AES-256. So, if your files got encrypted with a specific decryption key, which is totally and there are no other copies. The sad reality is that it is impossible to recover the information without the unique key available.

In case if Nppp worked in online mode, you can’t gain access to the AES-256 key. It is stored on a remote server owned by the criminals who distribute the Nppp ransomware.

For receiving decryption key the payment should be $980. To obtain the payment details, the victims are encouraged by the message to contact the frauds by e-mail (usually [email protected]), or via Telegram.

Do not pay for Nppp!

Please, try to use the available backups, or Decrypter tool

_readme.txt file also indicates that the computer owners must get in touch with the Nppp representatives during 72 hours starting from the moment of data where encrypted. On the condition of getting in touch within 72 hours, users will be granted a 50% rebate. Encryptor distributors also can force user to pay them via menacig to delete all encrypted files, or to drop any communications with him, so user gets face-to-face with ransomware. Thus the ransom amount will be minimized down to $490). Yet, stay away from paying the ransom!

I definitely recommend that you do not contact these crooks and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use Decrypter tool.

The peculiarity of all such viruses apply a similar set of actions for generating the unique decryption key to recover the ciphered data. They also can just hide inside your computer, until command server would give them an instruction to start their action

Thus, unless the ransomware is still under the stage of development or possesses some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.

Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation. There is no trouble for ransomware to find and encrypt your backup, so you are risking to lose your chance to restore files via backup.

For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

No reason to remind, that when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main computer is surely not a good idea.
