NetForceZ Ransomware

The Netforcez virus falls within the ransomware type of malicious agent. Malware of this type encrypts all the data on your computer (images, text files, excel sheets, music, videos, etc) and appends its own extension to every file, creating the ReadMe.txt text files in each directory with the encrypted files.

What is Netforcez virus?

Netforcez will append its specific .NetForceZ extension to every file’s name. For example, a file named “photo.jpg” will be changed to “photo.jpg.NetForceZ”. Likewise, the Excel sheet named “table.xlsx” will end up as “table.xlsx.NetForceZ”, and so forth.

In each directory that contains the encrypted files, a ReadMe.txt text document will appear. It is a ransom money note. It contains information on the ways of paying the ransom and some other remarks. The ransom note usually contains a description of how to purchase the decryption tool from the racketeers. You can get this decrypting software after contacting @xpolarized via email. That is how they do it.

How did Netforcez ransomware end up on my PC?

There is a huge number of possible ways of ransomware infiltration.

Nowadays, there are three most popular methods for hackers to have ransomware acting in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.

  • If you access your mailbox and see letters that look like familiar notifications from utility services companies, postal agencies like FedEx, web-access providers, and whatnot, but whose addresser is strange to you, beware of opening those emails. They are most likely to have a ransomware file attached to them. So it is even more dangerous to download any attachments that come with letters like these.
  • Another thing the hackers might try is a Trojan horse scheme. A Trojan is an object that infiltrates into your computer disguised as something different. Imagine, you download an installer for some program you want or an update for some software. However, what is unboxed reveals itself a harmful program that corrupts your data. As the update wizard can have any title and any icon, you have to make sure that you can trust the source of the stuff you’re downloading. The optimal thing is to use the software developers’ official websites.
  • As for the peer networks like torrents or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded items with the antivirus as soon as the downloading is done.

How to remove ransomware?

It is crucial to inform you that besides encrypting your data, the Netforcez virus will probably install Vidar Stealer on your computer to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can extract your logins and passwords from your browser’s auto-filling cardfile.

How to avoid ransomware injection?

Netforcez ransomware doesn’t have a endless power, neither does any similar malware.

You can armour your PC from ransomware attack in three easy steps:

  • Never open any letters from unknown senders with unknown addresses, or with content that has nothing to do with something you are waiting for (can you win in a lottery without even taking part in it?). In case the email subject is likely something you are waiting for, check all elements of the questionable email carefully. A fake email will surely contain a mistake.
  • Avoid using cracked or unknown software. Trojan viruses are often spreaded as a part of cracked products, most likely under the guise of “patch” to prevent the license check. But untrusted programs are difficult to distinguish from reliable software, as trojans sometimes have the functionality you seek. You can try searching for information about this software product on the anti-malware forums, but the optimal solution is not to use such software.

FAQ

🤔 How can I open “.NetForceZ” files?Are the “.NetForceZ” files accessible?

There’s no way to do it, unless the files “.NetForceZ” files are decrypted.

🤔 I really need to decrypt those “.NetForceZ” files ASAP. How can I do that?

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. There are other ways to beat ransomware, but they take time.

🤔 What should I do if the Netforcez malware has blocked my computer and I can’t get the activation code.

🤔 What could help the situation right now?

Many of the encoded files might still be within your reach

  • If you sent or received your critical files through email, you could still download them from your online mailbox.
  • You may have shared images or videos with your friends or relatives. Simply ask them to send those pictures back to you.
  • If you have initially got any of your files from the Web, you can try to do it again.
  • Your messengers, social networks pages, and cloud storage might have all those files as well.
  • Maybe you still have the needed files on your old computer, a notebook, phone, memory stick, etc.

USEFUL TIP: You can employ data recovery programs1 to retrieve your lost information since ransomware blocks the copies of your files, removing the authentic ones. In the tutorial below, you can see how to use PhotoRec for such a restoration, but be advised: you won’t be able to do it before you kill the ransomware itself with an antivirus program.
