Remove NPPP Ransomware Virus (2021 Removal Guide)

NPPP ransomware creators are greedy for money: encrypts data to scare victims

NPPP ransomware is the 210th version of DJVU virus which encrypts files on Windows computer systems. Victims affected by this virus discover that all files now have .nppp file extension and can no longer be opened. What is more, the virus drops _readme.txt notes containing a message from the criminals. The attackers suggest that the only way to decrypt corrupted data is to pay a ransom worth $490 (if paid within 3 days) or $980 (if paid later). They leave two contact emails so that the victim could contact them.

NPPP ransomware encrypts all files discovered on victim’s computer. It searches and affects all types of files, including documents, videos, audio files, images, archives, databases, and even more.

The file-encrypting malware turns data collected for years and years into junk in a few moments. Once the encryption is complete, the virus deletes Volume Shadow Copies and installs Azorult (Trojan that steals private information such as passwords, logins, etc.).

The message from the criminals demands money

The virus drops _readme.txt notes all over the computer. This file contains a threatening message from the attackers, who suggest that all files were encrypted with “the strongest encryption and unique key. The only method of recovering files is to purchase NPPP decrypt tool and unique key for you.“

The attackers suggest decrypting one chosen file for free as a proof of the decryption tool’s functionality. The victim needs to send the personal ID included in the ransom note to the criminals via helpdatarestore@firemail.cc or helpmanager@mail.ch. If there is no response, the victim is advised to check Spam or Junk folders.

In order to protect your file system and private information, remove NPPP ransomware virus as soon as you can. We suggest following the step-by-step guide provided below.

Why free decryption is almost impossible

The primary matter for each NPPP file virus’ victim is to figure out a way to decrypt files so that they could go back to their original state. Unfortunately, this STOP DJVU ransomware variant is extremely sophisticated and dangerous.

It is so because its encryption algorithm can be compared to the most secure mechanisms used to lock military-grade secrets. It would take a supercomputer and many years to crack just one encryption/decryption key pair. Therefore victims who were attacked by this virus should check for data backups instead.

However, you must know that NPPP ransomware uses online or offline key to encrypt files. Such encryption methods are described below.

STOP/DJVU encryption routine explained

• ONLINE encryption. The virus successfully connects to its remote server and gets the individual encryption key from there. Each victim gets assigned with individual encryption/decryption keys in criminals’ database. Free decryption is impossible.
• OFFLINE encryption. Such encryption uses an encryption key hidden in the ransomware itself. The offline encryption occurs if the virus fails to connect to its C&C server. Therefore, you can understand that the key is the same for all computers on which the connection to C&C failed.

You can check whether you’re affected by the offline key by going to C:/SystemID/PersonalID.txt file. If the key ends in t1, you might recover files in the future. Learn more about STOP Decryptor and known offline decryption keys here.

Distributon methods employed by ransomware developers

NPPP file virus, just like BBOO, OOSS, MMNN, MOOL or other DJVU versions, hunt for victims in a very specific way. The creators of the virus hide the malware in software cracks or other illegal paid software activation tools (for example, KMSPico).

We strongly recommend to follow cyber security experts’ advice and avoid ransomware attacks this way:

• Do not open suspicious links online, such as those aggressively promoting various download links, adult games, gambling, and similar sites;
• Never open links or attachments added to suspicious emails;
• Use RDP Gateways and use strong passwords;
• Enable real-time protection anti-malware solution.
