N1N1N1 Virus Remove and Restore .n1n1n1 Files

ransomware-on-focus-sensorstechforumA ransomware virus going by the name N1N1N1 has been reported to use a very stron encryption algorithm to encode the files of unsuspecting users. The virus leaves behind the .n1n1n1 file extension to every file it has encrypted along with ransom instructions, name “how return files” in .txt and .html document. In those instructions the victim is notified that the files can no longer be opened by this ransomware and is asked to make a ransom payoff of 1.5 BTC to get the files back. Everyone who has become victims of the N1N1N1 crypto-virus is strongly advised to follow the instructions in this article to remove this malware and use alternative methods to try and restore encrypted files instead of paying the ransom.

Data Recovery Tool Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.

N1N1N1 Ransomware – Spread

In order to be widespread and infect the maximum amount of victims, N1N1N1 may spread via Exploit kits, JavaScript and even other malware that may currently be residing on the victims computers. The N1N1N1 virus also may use malicious spam campaigns that distribute it’s payload as an e-mail attachment or via a malicious URL that may be placed along a convincing message, motivating the user to click on it. Not only this, but the N1N1N1 ransomware might also infect via malicious web links that may be sent out on various Social Media websites, like Facebook, Twitter and others. Those web links may cause a browser redirect and an infection via a drive by download. To cause a successful infection and slip by any antivirus software and firewalls the N1N1N1 virus may also use malware obfuscators that make it appear as if it is a legitimate application. If it attacks via an exploit kit, this virus takes advantage of an Exploit in Windows, which means that the cyber-criminals behind the N1N1N1 threat may have invested a lot of funds in such software.

N1N1N1 Ransomware – What Does It Do

As soon as it has infected your computer, the N1N1N1 virus may drop several types of malicious files on your computer:

.exe, .dll, .bat, .vbs, .tmp,

The malicious files may be programmed to perform various activities such as changing he wallpaper of the infected computer, changing settings in the registry, connect to the cyber-crooks server and most importantly encrypt the files in it. They may be located in the following folders under different, usually random names:


After having created the malicious files, the N1N1N1 virus may run it’s primary executable which encrypts the files on the compromised computer. The virus may also heavily modify the Windows Registry Editor to make the encryptor run again and again every time you start Windows.

The file types that N1N1N1 is looking for to encrypt are many, but they are primarily associated with often used files, such as:

  • Documents.
  • Audio files.
  • Image files.
  • Database Files.
  • Files associated with programs, like Photoshop, etc.

The N1N1N1 virus also cleverly skips the encryption of files that may pose a direct threat to the operating system and cause it to disfunction.

After having encrypted your files, the N1N1N1 ransomware leaves them with it’s distinctive .n1n1n1 file extension, for example:


The files can no longer be opened since their code structure is no longer the same.

After encrypting the files on a compromised machine, the N1N1N1 malware drops two files in each folder with encrypted files:


The ransom notes have the following ransom message:

“If you don’t speak english then use public online translators https://translate.google.com or https://www.bing.com/Translator or https://www.translate.com .
Your files encrypted.
To decrypt and return control to all your encrypted files you need :
1) Go to https://www.torproject.org/download/download-easy.html.en . Download Tor browser for windows.

The HTML document leads to the primary web page where the user can enter the decryption key after paying the ransom amount. After paying the user is provided with a decrypter and a master key to decode his files.


Remove N1N1N1 Ransomware and Decrypt .n1n1n1 Files

Before trying to restore the encrypted files, it is strongly advisable to get rid of this virus from your computer. You can follow the instructions below to remove N1N1N1 ransomware effectively, but it is also possible to remove it via an advanced anti-malware program automatically, swiftly and effectively.

The encryption algorithm used by the N1N1N1 ransomware is believed to be RSA cipher which generates a unique private and public keys after every infection. Direct decryption may be a time costly process and this is why researchers recommend not to pay any type of ransom money to cyber-criminals and to seek alternative solutions to decode the files, while a free decrypter is released out to the public. This is why we strongly advise using the alternative file restoration methods below in step “3. Restore files encrypted by N1N1N1” to help recover at least some of your files while a free decryptor is released which can happen in the near future. Make sure to often check this article as we will update it as soon as a free decryption method is discovered.
