The Bruhnet virus belongs to the Xorist ransomware family. Ransomware of such sort encrypts all user’s data on the computer (images, documents, excel tables, music, videos, etc) and adds its extra extension to every file, creating the КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt files in every directory with the encrypted files.
What is Bruhnet virus?
☝️ A scientifically accurate description for the Bruhnet is “a Xorist family ransomware infection”.
Bruhnet will add its specific .bruhnet extension to the title of each encrypted file. For example, an image entitled “photo.jpg” will be altered to “photo.jpg.bruhnet”. Just like the Excel sheet named “table.xlsx” will end up as “table.xlsx.bruhnet”, and so forth.
In every folder that contains the encoded files, a КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt text document will be created. It is a ransom money memo. Therein you can find information on the ways of contacting the racketeers and some other remarks. The ransom note usually contains a description of how to purchase the decryption tool from the Bruhnet developers. That is how they do it.
Bruhnet outline:
| Name | Bruhnet Virus |
| Ransomware family1 | Xorist ransomware |
| Extension | .bruhnet |
| Ransomware note | КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt |
| Detection | Win32/TrojanDownloader.Small.ARE, Trojan.Win32.Packre.pef, MSIL/ClipBanker.KY |
| Symptoms | Your files (photos, videos, documents) get a .bruhnet extension and you can’t open them. |
| Fix Tool | See If Your System Has Been Affected by Bruhnet virus |
In the image below, you can see what a folder with files encrypted by the Bruhnet looks like. Each filename has the “.bruhnet” extension added to it.
How did Bruhnet ransomware end up on my PC?
There is a huge number of possible ways of ransomware infiltration.
There are currently three most exploited ways for tamperers to have the Bruhnet virus settled in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.
If you access your mailbox and see emails that look like familiar notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose mailer is strange to you, beware of opening those emails. They are most likely to have a malicious file enclosed in them. Thus it is even more dangerous to download any attachments that come with letters like these.
As for the peer file transfer protocols like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never know what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is done.
How to remove the Bruhnet virus?
It is important to note that besides encrypting your files, the Bruhnet virus will probably install the Azorult Spyware on your PC to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned program can extract your logins and passwords from your browser’s auto-filling data.
Sometimes racketeers would decode several of your files so you know that they really have the decryption tool. As Bruhnet virus is a relatively recent ransomware, security software designers have not yet found a method to undo its work. Nevertheless, the decryption tools are constantly upgraded, so the solution may soon be available.
Of course, if the evildoers succeed in encoding someone’s critical data, the desperate person will probably fulfill their demands. However, paying a ransom gives no guarantee that you’re getting your data back. It is still dangerous. After getting the ransom, the racketeers may deliver a wrong decryption code to the injured party. There were reports about ransomware developers simply disappearing after getting the money without even writing back.
The optimal solution 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. Obviously, that might be insufficient. The most important thing could be that one you were working on when it all started. But at least it is something. It is also wise to scan your drives with the antivirus program after the system restoration.
Bruhnet is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Mmvb, Mmdt, Oopu, and some others. The two basic differences between them and the Bruhnet are the ransom amount and the method of encryption. The rest is almost identical: documents become encrypted, their extensions altered, ransom notes are created in every directory containing encrypted files.
Some fortunate users were able to decrypt the arrested files with the aid of the free software provided by anti-malware developers. Sometimes the racketeers mistakenly send the decoding key to the wronged in the ransom readme. Such an extraordinary fail allows the injured part to restore the files. But obviously, one should never expect such a chance. Make no mistake, ransomware is a tamperers’ instrument to lay their hands on the money of their victims.
How to avert ransomware infection?
Bruhnet ransomware doesn’t have a endless power, neither does any similar malware.
You can armour your PC from its attack in three easy steps:
- Never open any emails from unknown mailboxes with strange addresses, or with content that has nothing to do with something you are waiting for (can you win in a money prize draw without participating in it?). In case the email subject is more or less something you are expecting, check all elements of the suspicious letter with caution. A fake email will surely contain mistakes.
- Never use cracked or untrusted software. Trojan viruses are often distributed as a part of cracked software, most likely under the guise of “patch” which prevents the license check. Understandably, untrusted programs are very hard to distinguish from reliable ones, as trojans sometimes have the functionality you need. You can try searching for information on this software product on the anti-malware forums, but the optimal solution is not to use such programs at all.

Frequently Asked Questions
🤔 How can I open “.bruhnet” files?Can I somehow access “.bruhnet” files?
Unfortunately, no. You need to decipher the “.bruhnet” files first. Then you will be able to open them.
🤔 I really need to decrypt those “.bruhnet” files ASAP. How can I do that?
If the “.bruhnet” files contain some really important information, then you probably have them backed up. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. All other solutions require time.
🤔 What should I do if the Bruhnet malware has blocked my PC and I can’t get the activation code.
🤔 What can I do right now?
Some of the encrypted data can be located elsewhere.
- If you exchanged your important files through email, you could still download them from your online mailbox.
- You might have shared photographs or videos with your friends or family members. Just ask them to give those pictures back to you.
- If you have initially got any of your files from the Internet, you can try downloading them again.
- Your messengers, social networks pages, and cloud storage might have all those files as well.
- It might be that you still have the needed files on your old PC, a laptop, mobile, memory stick, etc.
HINT: You can employ data recovery programs5 to retrieve your lost information since ransomware arrests the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a recovery, but be advised: you can do it only after you kill the ransomware itself with an antivirus program.
Also, you can contact the following governmental fraud and scam sites to report this attack:
- In the United States: On Guard Online;
- In Canada: Canadian Anti-Fraud Centre;
- In the United Kingdom: Action Fraud;
- In Australia: SCAMwatch;
- In New Zealand: Consumer Affairs Scams;
- In France: Agence nationale de la sécurité des systèmes d’information;
- In Germany: Bundesamt für Sicherheit in der Informationstechnik;
- In Ireland: An Garda Síochána;
To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
