NSMF Ransomware – Infection Methods

NSMF ransomware could spread its infection with various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your PC will become infected. You can see the detections of such a file on the VirusTotal service:

NSMF ransomware might also distribute its payload file on social media and file-sharing services. Freeware found on the Web which is presented as useful might also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware found in the forum.

NSMF Ransomware – More Information

NSMF is a virus that encrypts your files and extorts you to pay a ransom to get them back to normal. Malware researchers have confirmed that it is a variant of the HiddenTear project.

NSMF ransomware could make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

The ransom message is stored in a file called readme.txt. Below, you can see the ransom message that is inside that file:

That ransom message reads the following:

Files has been encrypted with NSMF (Nigga Stone My Files)
Send me 5 bitcoins or pizza
And I also hate night clubs, desserts, being drunk.

The above ransom message of the NSMF ransomware states that your files are encrypted. Instructions are written on how to potentially get your data back by paying a ransom equal to five Bitcoins or a pizza. You shouldn’t do either as nobody could give you a guarantee for your files getting restored afterward. Furthermore, giving money to cybercriminals will likely motivate them to create more ransomware or do similar criminal activities.

NSMF Ransomware – Encryption Process

As NSMF ransomware is a HiddenTear variant it probably seeks to encrypt files with the following extensions:

→.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp

Files that get encrypted will receive the same extension appended to them which is .nsmf. Currently, the ransomware only encrypts files found in your Desktop folder. The encryption algorithm that is used is believed to be AES since it is a variant of HiddenTear.

The NSMF file cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the command stated above is executed that would make the encryption process more efficient as it will dismiss one of the ways for restoring your data. You could keep on reading below to see how you can potentially recover your data.
