MXF1BD Virus (.mxf1bd files) — How to remove virus?

The Mxf1bd virus belongs under the ransomware type of infection. Malware of such sort encrypts all the data on your computer (images, text files, excel tables, audio files, videos, etc) and adds its extra extension to every file, leaving the Инструкция.txt text files in every folder which contains the encrypted files.

What is Mxf1bd virus?

☝️ A strictly accurate denomination for the Mxf1bd is “a ransomware-type malicious agent”.

Mxf1bd will add its own .mxf1bd extension to the name of every encrypted file. For example, a file named “photo.jpg” will be altered to “photo.jpg.mxf1bd”. Just like the Excel file named “table.xlsx” will be altered to “table.xlsx.mxf1bd”, and so on.

In each folder with the encoded files, a Инструкция.txt text file will be created. It is a ransom money note. Therein you can find information about the ways of paying the ransom and some other remarks. The ransom note usually contains instructions on how to purchase the decryption tool from the Mxf1bd developers. That is basically the scheme of the crime.

In the screenshot below, you can see what a folder with files encrypted by the Mxf1bd looks like. Each filename has the “.mxf1bd” extension appended to it.

How did Mxf1bd ransomware end up on my PC?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most exploited ways for malefactors to have the Mxf1bd virus acting in your digital environment. These are email spam, Trojan injection and peer file transfer.

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

As for the peer networks like BitTorrent or eMule, the danger 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. Our suggestion is that you use trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded files with the antivirus as soon as the downloading is done.

How do I get rid of the Mxf1bd virus?

It is crucial to inform you that besides encrypting your files, the Mxf1bd virus will probably deploy the Azorult Spyware on your PC to seize your credentials to different accounts (including cryptocurrency wallets). That program can extract your credentials from your browser’s auto-filling data.

Often tamperers would decrypt few of your files to prove that they really have the decryption program. Since Mxf1bd virus is a relatively recent ransomware, security software designers have not yet found a way to reverse its work. Nevertheless, the decryption tools are frequently upgraded, so the effective countermeasure may soon be available.

Sure thing, if the evildoers succeed in encrypting victim’s critical data, the hopeless person will most likely comply with their demands. Nevertheless, paying to racketeers does not necessarily mean that you’re getting your data back. It is still risky. After receiving the money, the racketeers may send a wrong decryption code to the victim. There were reports of hackers just disappearing 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 drive. Of course, that might be not enough. Your 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 drives with the anti-malware utility after the OS restoration.

Mxf1bd 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 Qbaa, Fgui, Fgnh, and some others. The two main differences between them and the Mxf1bd are the ransom amount and the method of encryption. The rest is almost identical: files become encrypted, their extensions changed, ransom notes emerge in every folder containing encoded files.

Some fortunate people were able to decode the arrested files with the aid of the free software provided by anti-malware specialists. Sometimes the criminals mistakenly send the decryption key to the wronged in the ransom note. Such an extraordinary fail allows the victim to restore the files. But obviously, one should never rely on such a chance. Make no mistake, ransomware is a tamperers’ instrument to pull the money out of their victims.

How to avert ransomware infection?

Mxf1bd ransomware has no superpower, neither does any similar malware.

You can defend your system from its attack 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 expecting (how can you win in a money prize draw without even taking part in it?). If the email subject is likely something you are expecting, check all elements of the dubious letter with caution. A hoax letter will surely contain a mistake.
  • Do not use cracked or untrusted programs. Trojan viruses are often spreaded as a part of cracked software, possibly as a “patch” which prevents the license check. But dubious programs are difficult to tell from trustworthy ones, as trojans may also have the functionality you seek. Try searching for information on this software product on the anti-malware forums, but the best way is not to use such software.

FAQ

🤔 How can I open “.mxf1bd” files?Can I somehow access “.mxf1bd” files?

Unfortunately, no. You need to decipher the “.mxf1bd” files first. Then you will be able to open them.

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

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. 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. All other solutions require time.

🤔 What actions should I take if the Mxf1bd ransomware has blocked my PC and I can’t get the activation code.

🤔 What could help the situation right now?

Many of the encrypted files might still be within your reach

  • If you sent or received your important files by email, you could still download them from your online mailbox.
  • You may have shared photographs or videos with your friends or family members. Just ask them to give those images back to you.
  • If you have initially downloaded any of your files from the Internet, you can try doing it again.
  • Your messengers, social networks pages, and cloud drives might have all those files as well.
  • Maybe you still have the needed files on your old PC, a laptop, mobile, flash memory, etc.

HINT: You can employ file recovery utilities4 to get your lost data back since ransomware encodes the copies of your files, removing the original ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but be advised: you can do it only after you kill the ransomware itself with an anti-malware program.

Also, you can contact the following official fraud and scam sites to report this attack:

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.
