HUIS_BN Virus Files of Ransomware — How to remove?

The Huis_bn virus falls within the Xorist ransomware family. Ransomware of such sort encrypts all user’s data on the PC (photos, documents, excel tables, music, videos, etc) and adds its extra extension to every file, leaving the КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt files in every folder with the encrypted files.

What is Huis_bn virus?

☝️ A strictly accurate designation for the Huis_bn is “a Xorist family ransomware malicious agent”.

Huis_bn will add its own .huis_bn extension to every file’s name. For example, a file named “photo.jpg” will be changed to “photo.jpg.huis_bn”. Just like the Excel file named “table.xlsx” will be changed to “table.xlsx.huis_bn”, and so on.

In each directory with the encrypted files, a КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt file will appear. It is a ransom money memo. It contains information about 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 tamperers. That is it.

In the picture below, you can see what a directory with files encrypted by the Huis_bn looks like. Each filename has the “.huis_bn” extension appended to it.

How did Huis_bn ransomware end up on my PC?

There are plenty of possible ways of ransomware injection.

There are currently three most popular ways for malefactors to have ransomware acting in your system. These are email spam, Trojan infiltration and peer-to-peer file transfer.

If you access your mailbox and see emails that look like familiar notifications from utility services companies, delivery agencies like FedEx, web-access providers, and whatnot, but whose addresser is unknown to you, be wary of opening those emails. They are most likely to have a malicious item enclosed in them. Therefore, it is even riskier to open any attachments that come with emails like these.

As for the peer-to-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. So you’d better be using trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded items with the antivirus as soon as the downloading is complete.

How do I get rid of the Huis_bn virus?

It is important to inform you that besides encrypting your files, the Huis_bn virus will probably deploy the Azorult Spyware on your computer to seize your credentials to different accounts (including cryptocurrency wallets). That program can derive your credentials from your browser’s auto-filling cardfile.

Sometimes criminals would decrypt some of your files to prove that they really have the decryption tool. Since Huis_bn virus is a relatively new ransomware, anti-malware engineers have not yet found a way to undo its work. Nevertheless, the anti-ransomware tools are frequently updated, so the solution may soon be available.

Sure thing, if the tamperers succeed in encrypting someone’s critical data, the hopeless person will probably comply with their demands. Despite that, paying a ransom does not necessarily mean that you’re getting your blocked information back. It is still dangerous. After obtaining the ransom, the racketeers may send a wrong decryption code to the injured party. There were reports of criminals simply disappearing after getting the money without even bothering to reply.

The best safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud storage or at least on an external drive. Surely, that might be insufficient. Your most crucial thing could be that one you were working on when it all went down. But at least it is something. It is also wise to scan your drives with the antivirus program after the system is rolled back.

There are other ransomware products, besides Huis_bn, that work similarly. Examples of those are Ygvb, Tuid, Udla, and some others. The two basic differences between them and the Huis_bn are the ransom amount and the method of encryption. The rest is almost identical: files become inaccessible, their extensions altered, ransom notes are found in every directory containing encrypted files.

Some fortunate victims were able to decrypt the arrested files with the aid of the free tools provided by anti-malware developers. Sometimes the hackers mistakenly send the decoding key to the victims in the ransom readme. Such an extraordinary fail allows the user to restore the files. But naturally, one should never rely on such a chance. Make no mistake, ransomware is a tamperers’ technology to pull the money out of their victims.

How сan I avert ransomware infection?

Huis_bn ransomware doesn’t have a superpower, neither does any similar malware.

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

• Ignore any emails from unknown senders with strange addresses, or with content that has likely no connection to 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, check all elements of the suspicious letter with caution. A hoax email will always contain a mistake.
• Avoid using cracked or unknown programs. Trojans are often spreaded as a part of cracked products, most likely under the guise of “patch” which prevents the license check. Understandably, potentially dangerous programs are very hard to tell from trustworthy software, because trojans sometimes have the functionality you need. You can try to find information about this software product on the anti-malware forums, but the best solution is not to use such programs at all.

Frequently Asked Questions

🤔 How can I open “.huis_bn” files?Can I somehow access “.huis_bn” files?

Unfortunately, no. You need to decipher the “.huis_bn” files first. Then you will be able to open them.

🤔 What should I do to make my files accessible as fast as possible?

If the “.huis_bn” 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. The rest of the methods require patience.

🤔 What actions should I take if the Huis_bn virus has blocked my PC and I can’t get the activation code.

🤔 And what should I do now?

Some of the encrypted data can be located elsewhere.

• If you sent or received your critical files by email, you could still download them from your online mail server.
• You might have shared images or videos with your friends or relatives. Simply ask them to give those pictures back to you.
• If you have initially downloaded any of your files from the Internet, you can try to do it again.
• Your messengers, social media pages, and cloud disks might have all those files too.
• Maybe you still have the needed files on your old PC, a laptop, mobile, memory stick, etc.

USEFUL TIP: You can use data recovery utilities⁵ to retrieve your lost information since ransomware blocks the copies of your files, deleting the authentic ones. In the video below, you can see how to use PhotoRec for such a restoration, but remember: you can do it only after you remove the virus 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.
