What is Nifr virus/ransomware?
Nifr is a type of ransomware that primarily targets Microsoft Windows users. The malware uses advanced techniques to lock a victim’s data and demands payment from the victim to provide the key to decrypt the files. Nifr is usually spread through social engineering, and malicious software bundling.
Once Nifr is executed, it creates a folder in the Windows system directory and changes some settings to ensure it starts up every time the computer is restarted. The malware then attempts to establish a connection with its command server to receive an encryption key. If a connection is established, Nifr sends information about the infected computer to the server and receives the key in return. If the virus cannot connect to its command server, it uses a fixed encryption key.
Nifr uses a strong encryption algorithm to encrypt files and skips some files, including those located in Windows system directories and those with specific extensions or names. Each encrypted file is renamed with the “.Nifr” extension, and the virus places a file called “_readme.txt” in every directory with encrypted files. The file contains a message from the attackers demanding payment to restore access to the encrypted files.
The ransom note typically warns the victim not to attempt to decrypt the files using third-party tools, as it may lead to permanent data loss. The attackers also provide instructions on how to purchase the decryption tool and unique key to restore the encrypted files.
It is worth noting that there are free decryptors available that can restore files encrypted by Nifr, such as the Emsisoft decryptor. Additionally, victims can explore alternative ways of restoring their data. However, as Nifr is a severe threat that can cause significant damage, it is crucial to take precautionary measures to prevent infection in the first place. Users can protect themselves from Nifr and other ransomware threats by avoiding suspicious links and email attachments, using reputable anti-virus software, and regularly backing up their data to an external source. Being aware of the latest trends in cybersecurity and keeping your operating system and software up-to-date are also essential to minimize the risk of a ransomware attack.

Steps to determine the type of key used for file encryption
To decrypt files encrypted by Nifr File Decrypt Tool, it is important to know which key was used during encryption. You can find out the type of key used through two methods. Both methods are effective, but the second method is considered to be more accurate and therefore recommended.
Identifying the Type of Key Using the ‘_readme.txt’ File
- Open the ‘_readme.txt’ file, which is the ransom demand message created by the Nifr ransomware.
- Scroll down to the end of the file.
- Look for a line of text that says ‘Your personal ID’.
- Below this line, you should see a string of characters. This is your personal ID, which is unique to your computer and is used to generate the decryption key.
Identifying the Type of Key Using the ‘_readme.txt’ File
- Open the C drive on your computer.
- Open the ‘SystemID’ directory.
- Look for the ‘PersonalID.txt’ file and open it./li>
- This file contains a list of ‘Personal IDs’ that match the keys that the ransomware used to encrypt files./li>
The ‘Personal ID’ is not the actual key that was used to encrypt files, but rather an identifier that corresponds to it. If the ID ends with ‘t1’, the files were encrypted with an offline key, whereas if it does not, the Nifr virus used an online key. If you are unable to determine which key was used, you can request assistance by submitting a query here or in the comments section.
