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 jbvetobit@anonym.im through email. That is pretty much the scheme of the crime.

In the image below, you can see what a folder with files encrypted by the Nobit looks like. Each filename has the “.bit” extension appended to it.
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.
- If you open your mailbox and see letters that look like familiar notifications from utility services companies, postal agencies like FedEx, Internet providers, and whatnot, but whose sender is strange to you, be wary of opening those emails. They are most likely to have a malware item enclosed in them. So it is even riskier to download any attachments that come with letters like these.
- 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.

Sometimes racketeers would unblock some of your files so you know that they do have the decryption program. Since Nobit virus is a relatively recent ransomware, safety measures designers have not yet found a way to reverse its work. However, the decoding tools are constantly updated, so the effective countermeasure may soon arrive.
Sure thing, if the malefactors do the job of encrypting someone’s essential files, the hopeless person will probably comply with their demands. However, paying to criminals gives no guarantee that you’re getting your files back. It is still dangerous. After obtaining the money, the racketeers may send a wrong decryption key to the injured party. There were reports of criminals simply vanishing after getting the ransom without even writing back.
The best safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud disk or at least on an external disk. Surely, that might be not enough. The most important thing could be that one you were working upon when it all happened. But at least it is something. It is also advisable to scan your PC for viruses with the anti-malware utility after the OS is rolled back.
Nobit is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. For instance, Jaqw, Jasa, Jaoy, and some others. The two basic differences between them and the Nobit are the ransom amount and the encoding method. The rest is the same: documents become blocked, their extensions altered, ransom notes are found in each directory containing encoded files.
Some lucky users were able to decrypt the arrested files with the help of the free software provided by anti-ransomware experts. Sometimes the criminals mistakenly send the decryption key to the wronged in the ransom note. Such an extraordinary fail allows the injured part to restore the files. But naturally, one should never expect such a chance. Remember, ransomware is a tamperers’ instrument to pull the money out of their victims.
How Ρan I avert ransomware infiltration?
Nobit ransomware doesnβt 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 βpatchβ 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.
- And to be sure about the safety of the files you downloaded, use GridinSoft Anti-Malware. This program will be a powerful defense for your system.
FAQ
π€ 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.
π€ The encrypted files are very important to me. How can I decrypt them quickly?
If the β.bitβ 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.
π€ If GridinSoft deletes the Nobit malware, will it also delete my files that were encrypted?
No way! The encrypted files are not harmful, so they won’t be deleted.
GridinSoft Anti-Malware will remove actual threats from your computer. The ransomware that has attacked your system is most likely still active and running scans from time to time to encode any new files you might create on your computer after the attack. As it has been said above, the Nobit virus does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide malefactors with easy access to your PC after some time.
π€ What to do if the Nobit ransomware has blocked my PC and I can’t get the activation key.
In such an unfortunate situation, you need to have a memory stick with a pre-installed Trojan Killer. Use Safe Mode to perform the procedure. You see, the ransomware runs automatically as the system launches and encrypts any new files created or brought into your PC. To block this function – use Safe Mode, which allows only the vital programs to run upon system boot. Consider reading our manual on running Windows in Safe Mode.
π€ 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.
