BASN Virus 🔐 (.BASN Files) — How to Remove?

The Basn virus belongs to the ransomware type of infection. A harmful program of this type encrypts all the data on your computer (images, text files, excel sheets, music, videos, etc) and adds its extra extension to every file, leaving the unlock your files.txt text files in each folder with the encrypted files.

It is better to prevent, than repair and repent!

What is known about the Basnvirus?

☝️ A scientifically correct designation for the Basn would be “a ransomware-type malicious agent”.

Basn adds its extra .basn extension to every file’s title. For instance, an image named “photo.jpg” will be turned into “photo.jpg.basn”. Just like the Excel sheet named “table.xlsx” will end up as “table.xlsx.basn”, and so forth.

In every folder that contains the encoded files, a unlock your files.txt file will be found. It is a ransom money note. It contains information about the ways of paying the ransom and some other information. The ransom note usually contains a description of how to buy the decryption tool from the tamperers. That is how they do it.

Basn abstract:

In the image below, you can see what a directory with files encrypted by the Basn looks like. Each filename has the “.basn” extension added to it.

That is how encrypted “.basn” files look.

How did my computer get infected with Basn ransomware?

There are plenty of possible ways of ransomware infiltration.

There are currently three most exploited methods for criminals to have ransomware acting in your digital environment. These are email spam, Trojan injection and peer networks.

If you open your mailbox and see letters that look just like notifications from utility services providers, postal agencies like FedEx, web-access providers, and whatnot, but whose mailer is strange to you, beware of opening those letters. They are most likely to have a harmful file enclosed in them. So it is even more dangerous to download any attachments that come with letters like these.

Another option for ransom hunters is a Trojan virus model¹. A Trojan is an object that gets into your computer pretending to be something legal. For instance, you download an installer for some program you need or an update for some software. However, what is unboxed reveals itself a harmful program that encodes your data. Since the update package can have any title and any icon, you have to make sure that you can trust the source of the files you’re downloading. The optimal thing is to use the software companies’ official websites.

As for the peer file transfer protocols like BitTorrent or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the directory containing the downloaded files with the antivirus as soon as the downloading is finished.

How to remove the Basn virus?

It is important to inform you that besides encrypting your data, the Basn virus will most likely install the Azorult Spyware on your computer to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned program can extract your logins and passwords from your browser’s auto-filling data.

Sometimes tamperers would unblock few of your files so you know that they indeed have the decryption tool. Since Basn virus is a relatively recent ransomware, safety measures engineers have not yet found a way to undo its work. However, the decryption tools are constantly updated, so the effective countermeasure may soon arrive.

Understandably, if the hackers do the job of encoding victim’s essential files, the hopeless person will probably comply with their demands. Despite that, paying to criminals does not necessarily mean that you’re getting your files back. It is still dangerous. After receiving the ransom, the racketeers may send a wrong decryption key to the victim. There were reports about ransomware developers simply disappearing after getting the money without even writing back.

The best solution against ransomware is to have aan OS restore point or the copies of your essential files in the cloud disk or at least on an external disk. Obviously, that might be not enough. The most important thing could be that file you were working upon when it all went down. But at least it is something. It is also wise to scan your PC for viruses with the anti-malware utility after the system restoration.

Basn 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 Goaq, Qotr, Coaq, and some others. The two major differences between them and the Basn are the ransom amount and the method of encryption. The rest is almost identical: documents become encrypted, their extensions changed, ransom notes are found in every directory containing encrypted files.

Some fortunate users were able to decode the arrested files with the help of the free tools provided by anti-ransomware developers. Sometimes the racketeers accidentally send the decryption code to the victims in the ransom readme. Such an extraordinary fail allows the victim to restore the files. But naturally, one should never rely on such a chance. Remember, ransomware is a tamperers’ tool to lay their hands on the money of their victims.

How сan I avoid ransomware injection?

Basn ransomware doesn’t have a superpower, so as any similar malware.

You can protect your system from its infiltration within several easy steps:

• Never open any emails from unknown mailboxes 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 expecting, scrutinize all elements of the suspicious letter with caution. A hoax letter will always contain a mistake.
• Avoid using cracked or unknown software. Trojan viruses are often shared as an element of cracked software, possibly as a “patch” to prevent the license check. But untrusted programs are very hard to tell from reliable ones, as trojans sometimes have the functionality you seek. Try searching for information about this program on the anti-malware forums, but the best solution is not to use such software.
• And to be sure about the safety of the files you downloaded, scan them with GridinSoft Anti-Malware. This program will be a perfect defense for your personal computer.

Frequently Asked Questions

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

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

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

Hopefully, you have made a copy of those important files. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. There are other ways to beat ransomware, but they take time.

🤔 Will GridinSoft Anti-Malware remove all the encrypted files alongside the Basn virus?

No way! Your encrypted files are no threat to your PC.

With the help of GridinSoft Anti-Malware, you can clean your PC off the actual threats. The ransomware that has infiltrated your PC is must be still active and launching checks every so often to encode any new files you might create on your PC after the initial attack. As it has been said above, the Basn virus does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide hackers with easy access to your system in the future.

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

In such a case, you need to have a flash memory drive with a previously installed Trojan Killer. Use Safe Mode to execute the procedure. You see, the ransomware runs automatically as the system boots and encrypts any new files created or imported into your computer. To stop this function – use Safe Mode, which allows only the vital programs to run automatically. Consider reading our manual on running Windows in Safe Mode.

🤔 What could help the situation right now?

Many of the encrypted files might still be at your disposal

• If you sent or received your critical files via email, you could still download them from your online mail server.
• You might have shared photographs or videos with your friends or relatives. Just ask them to post 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 disks might have all those files as well.
• It might be that you still have the needed files on your old computer, a notebook, mobile, external storage, etc.

HINT: You can employ data recovery programs⁴ to get your lost data back since ransomware arrests the copies of your files, deleting the original ones. In the tutorial below, you can see how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you remove the ransomware itself with an anti-malware program.

Also, you can contact the following official 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.
