.NM4 File Virus – Infection
The .NM4 file virus could distribute its infection through many diverse methods. One method that is observed to be very commonly utilized is with the help of a payload file. That file launches the malicious script of the ransomware, which in turn infects your computer device. Such payloads are currently spread around the Internet and you should be cautious when browsing the Web.
.NM4 file virus could also distribute its payload file on social media websites and file-sharing networks. Freeware applications which are found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Avoid opening files straight away after you have downloaded them. That stands especially for ones that came from sources like suspicious e-mails or links. What you should rather do is to scan files before opening them with a security tool, while also checking their size and signatures for anything dubious.

Your Key: [redacted]
The makers of the NM4 ransomware are using the TOR network for their ransom payment pages. The following three addresses are currently being used:
Upon loading any of the three URLs provided above, the following “Login” page will load:
From there, you will be asked to enter your ID and the following message about ransom payment will show:
From the above picture, you can clearly see that the cybercriminals who own the .NM4 file virus demand a ransom price of 3 Bitcoin, which equates to nearly 3.858 US dollars. You should NOT under any circumstances contact the cybercriminals, nor pay up. Nobody could give you a guarantee that your files will get recovered if you pay the ransom. Besides, financially supporting cybercriminals is a genuinely bad idea. That will probably inspire the crooks to continue making ransomware viruses or get involved in more criminal activities.
.NM4 File Virus – Encryption
The .NM4 file virus ransomware will encrypt files on your PC, which are from these file type categories:
Currently, a list with file extensions which could be targeted is non-existent. The article will get duly updated if such a list is discovered.Every file that gets encrypted will receive the .NM4 extension appended to it. In the encryption process, a mixture of both the AES and RSA algorithms is being used. More precisely, AES 256-bit and RSA 2048-bit algorithms are used, or at least that is according to the ransom note.
The .NM4 file virus cryptovirus erases the Shadow Volume Copies from the Windows operating system. That makes the encryption process more viable since it eliminates one of the ways for file decryption. The following command with one or more subcommands is initiated:
→vssadmin.exe delete shadows /all /Quiet
