What is NSMF ransomware virus?

Developers of NSMF ransomware asks to pay more than $13.500 for data recovery

Ransom note by NSMF ransomware virus

NSMF is a new ransomware[1] that encrypts files using AES cryptography. It belongs to the group of Hidden Tear based viruses and during data encryption appends .nsmf file extension.

Following data encryption, malware drops a ransom note called readme.txt. The message does not look like a real letter from cyber criminals. It sounds more like a joke.

The ransom note informs that user’s files were encrypted by NSMF (Nigga Stone My Files). In order to get back access to the data, users have to pay 5 Bitcoins or send a pizza. However, location, where pizza's order should be delivered, is not provided.

Currently, 5 Bitcoins equals to more than $13.500. Thus, hacker asks for an enormous amount of money. However, does not provide clear instructions about the transaction. It seems that paying the ransom is not a data recovery option.

Furthermore, developer of the ransomware talks about things he or she hates. It includes night clubs, desserts and being drunk. What victims can do with this information we cannot tell. However, we are certain that once you read this ransom note, you have to remove NSMF from the PC using FortectIntego.

Nevertheless, the ransom demanding message does not seem real; the virus is actually capable of encrypting files. It aims at the most popular file extensions and might encrypt Microsoft Office, various multimedia, databases, archives, etc.

One .nsmf file extension is added to each of the targeted files; victims cannot open and use them. However, it might be possible to restore data from backups, using Hidden Tear Decrypter or other third-party software.

Nevertheless, data recovery seems like the most important task; it’s not. First of all, you have to focus on NSMF removal. Only then you can look up for the best recovery solution.

Ransomware elimination is important because this cyber threat makes computer’s system vulnerable and might open backdoor. Thus, your PC might suffer from other cyber attacks.

The most common ways to get infected with ransomware

Authors of the NSMF virus is suspected of using multiple distribution methods:

  • malicious spam emails and their attachments;
  • fake downloads;
  • malvertising.[2]

These three distribution strategies are common among cyber criminals. Thus, you have to be aware of these methods in order to avoid similar cyber threats in the future.

Malicious spam emails are the most popular ransomware distribution technique. Crooks use social engineering techniques and send thousands of different phishing emails that include malicious links or attachments. Once they are clicked/opened, the payload is executed on the system.

Before opening Word, PDF or other safe-looking files, you have to look up for suspicious details that might identify a dangerous content. Usually, email services mark such emails as dangerous. However, crooks are getting better and better in bypassing security filters.

NSMF might also be distributed as a fake program on various file-sharing websites, P2P networks or torrents. If you need to install particular software, please choose credible download sources, such as publisher’s site.

When browsing the web, you might encounter numerous online ads. Nevertheless, they might promote useful stuff; some of them might include malware.

We recommend staying away from online ads that notify about won prizes, delivers security alerts or delivers huge discounts for expensive products because they are usually dangerous.

Guide which is presented above is supposed to help you remove NSMF from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

There are several ways how you can try to recover your files. However, the best method is backups. But if you do not have them, please try methods described below.

If your files are encrypted by NSMF, you can use several methods to restore them:

  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by NSMF ransomware;
  • Restore them.

Take advantage of Windows Previous Versions feature

If System Restore has been activated before ransomware attack, you can try this useful Windows feature. By following steps below, you can access previously saved versions of encrypted files.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
