NoBit Virus 🔐 (.BIT File) Wire – @vetobit

The Nobit virus falls under the ransomware type of infection. Harmful software of this type encrypts all the data on your PC (images, documents, excel tables, music, videos, etc) and appends its extra extension to every file.

What is known about the Nobit virus?

Nobit adds its extra .bit extension to every file’s name. For instance, a file named “photo.jpg” will be renamed to “photo.jpg.bit”. In the same manner, the Excel sheet named “table.xlsx” will be altered to “table.xlsx.bit”, and so on.

The ransom note usually contains a description of how to purchase the decryption tool from the tamperers. You can get this tool after contacting [email protected] through email. That is pretty much the scheme of the crime.

How did Nobit ransomware end up on my PC?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most exploited methods for criminals to have the Nobit virus working in your digital environment. These are email spam, Trojan introduction and peer file transfer.

  • Another thing the hackers might try is a Trojan horse model. A Trojan is a program that infiltrates into your machine disguised as something different. For instance, you download an installer for some program you want or an update for some service. However, what is unpacked reveals itself a harmful agent that encodes your data. As the installation wizard can have any name and any icon, you’d better be sure that you can trust the resource of the files you’re downloading. The optimal way is to use the software companies’ official websites.
  • As for the peer networks like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you’d better be using trustworthy resources. Also, it is reasonable to scan the directory containing the downloaded objects with the antivirus as soon as the downloading is done.

How to remove ransomware?

It is crucial to note that besides encrypting your files, the Nobit virus will most likely deploy Vidar Stealer on your machine to seize your credentials to different accounts (including cryptocurrency wallets). That spyware can extract your logins and passwords from your browser’s auto-filling cardfile.

How сan I avert ransomware infiltration?

Nobit ransomware doesn’t have a endless power, so as any similar malware.

You can defend your computer from its attack in three easy steps:

  • Ignore any emails from unknown mailers with unknown addresses, or with content that has nothing to do with something you are waiting for (how can you win in a lottery without even taking part in it?). In case the email subject is more or less something you are expecting, scrutinize all elements of the suspicious letter carefully. A hoax email will surely contain mistakes.
  • Do not use cracked or unknown programs. Trojan viruses are often distributed as an element of cracked software, possibly under the guise of “patch” which prevents the license check. But dubious programs are very hard to tell from reliable software, because trojans sometimes have the functionality you seek. Try to find information about this software product on the anti-malware message boards, but the optimal solution is not to use such software.

FAQ

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

Negative. That is why ransomware is so frustrating. Until you decode the “.bit” files you will not be able to access them.

🤔 The encrypted files are very important to me. How can I decrypt them quickly?

If the “.bit” files contain some really important information, then you probably have them backed up. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. The rest of the methods require patience.

🤔 What to do if the Nobit ransomware has blocked my PC and I can’t get the activation key.

🤔 And what should I do now?

Many of the encrypted files might still be at your disposal

  • If you sent or received your important files through email, you could still download them from your online mail server.
  • You may have shared images or videos with your friends or family members. Just ask them to send those pictures back to you.
  • If you have initially downloaded any of your files from the Web, you can try to do it again.
  • Your messengers, social media pages, and cloud storage might have all those files as well.
  • It might be that you still have the needed files on your old computer, a notebook, cellphone, external storage, etc.

USEFUL TIP: You can employ data recovery utilities1 to get your lost data back since ransomware arrests 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 remember: you can do it only after you kill the virus with an antivirus program.
