What is Bbnm virus (ransomware)?
Bbnm virus is a new ransomware virus. A ransomware virus is a malicious program that encrypts files and then displays a ransom message on the computer screen. In some cases, the virus does not show the ransom demand message on the screen, but saves it to a specially created file. This file is located in the root of the hard drive or in directories where files are encrypted. Ransomware viruses often rename encrypted files, thus trying to attract the attention of the computer user. Bbnm ransomware encrypts the files and then renames them by adding the extension “.bbnm” to their name. For example, a file named “photo.jpg” will be renamed to “photo.jpg.bbnm”, the file “document.docx” to “document.docx.bbnm” and so on. This virus does not display the ransom demand message on the screen, but saves it in the file “_readme.txt”. The virus places this file in different directories on the hard drive. The content of the file does not depend on its location, it is the same.
Files encrypted with .bbnm extension
Almost always, ransomware viruses display a ransom message on the screen or place it in a file. This message contains an instruction stating that the user’s files are encrypted. In addition, it contains the contact information of the ransomware authors. In some cases, a ransom demand message also contains the ransom size and e-wallet address. Bbnm places a ransom demand message in files named “_readme.txt”. These files say that the victim’s files are encrypted with strong encryption and a unique key. The attackers claim that encrypted files cannot be decrypted without a decryptor and a key. They demand $980 for a decryptor-key pair and offer a 50% discount to all victims who contact them within 72 hours of the files being encrypted. The Bbnm creators left two email addresses for communication: helpteam@mail.ch and helpmanager@airmail.cc.
QUICK LINKS:
Paying the ransom does not guarantee that attackers will contact you and provide a decryptor and a key. There are many stories on the Internet in which victims of ransomware report that after they paid, they received nothing – neither a decryptor nor a key. However, victims of ransomware often have no choice but to pay the ransom or restore files from backups. In the case of the Bbnm virus, there is a chance to recover some or even all of the encrypted files. How to do this is described in detail below. But in any case, if your computer is infected with Bbnm virus, you need to isolate the infected computer as soon as possible, find and remove the virus. This will help prevent more files from being encrypted.

The most common method for distributing ransomware is through torrents and file-sharing sites. Attackers disguise ransomware as cracked programs and games, key generators and Windows activators. A file containing ransomware is an archive containing another archive with a program and a small text file. This text file contains a password and a message that says that the user needs to disable the antivirus and use the given password to unpack the internal archive. In reality, the unpacked file is a Trojan designed to download and launch ransomware.

Is my computer infected with Bbnm virus?
Determining whether a computer is infected or not is quite easy. Try opening your files, such as documents, photos, music, etc. in relevant programs. If, for example, when you open a document, Windows reports that the file is of an unknown type, then most likely the document is encrypted and the computer is infected. Of course, the presence of files with the extension .bbnm and files with the name _readme.txt is also a 100% sign of ransomware infection.

How to decrypt .bbnm files
Since Bbnm virus belongs to Stop (djvu) ransomware, ‘STOP (djvu) decryptor’ can be used to decrypt .bbnm files. STOP (djvu) decryptor is a free tool that is created by Emsisoft to decrypt files that were encrypted by malware belonging to Stop ransomware family.
Free .bbnm decryptor (Emsisoft decryptor for stop djvu)
How to use STOP (Bbnm) decryptor to decrypt .bbnm files
- Visit the page linked below to download .bbnm decryptor
STOP Djvu decryptor - Scroll down to ‘New Djvu ransomware’ section.
- Download the ‘decrypt_STOPDjvu.exe’ file to your desktop.
- Run decrypt_STOPDjvu.exe
- Select the directory or drive where the encrypted files are located.
- Click the Decrypt button.
Unfortunately, STOP (djvu) decryptor can decrypt the ecnrypted files only if they were encrypted using the so-called OFFLINE keys, which were obtained by EmsiSoft. OFFLINE keys are the encryption keys that the ransomware uses when the infected computer does not have an Internet connection or its command server was not available for connection. If the STOP (Djvu) decryptor skips encrypted files without decrypting them, then you still have a chance to recover the contents of the encrypted files. To do this, use the steps listed below.
How to restore .Bbnm files
Unfortunately, free Bbnm decryptor is not always able to decrypt files. But even in this case, it is possible to restore the contents of encrypted files. Below in this article we will give several ways, please try all of them. Perhaps one of them will allow you to completely restore the files, or rather, return them to their original state, to the state that was before their encryption.
At this stage, I want to emphasize that before recovering files, you must definitely check your computer for viruses, find and remove malware that encrypted your files. The only way to skip this step is to get the disk with encrypted files and connect it to another computer, then use it to restore your files. Attention, using a disk on another computer, there is a small chance that you accidentally infect that computer with this virus.
Restore .bbnm files using ShadowExplorer
To restore documents, photos, databases and other important files, that is, practically “decrypt .bbnm files without a key,” we first recommend using a free program called ShadowExplorer. If you have not come across this program, then here is some information about it. It is a small utility that allows you to easily access copies of files that are created automatically by a standard Windows function called ‘Windows Previous Versions’.
Download the program using the link that you can find below. We recommend that you save the downloaded file to your desktop, so you can easily find it after the download is complete.
When the program download is complete, you will see a file called ShadowExplorer-0.9-portable.zip. The utility is in the archive, so you need to unzip the archive before starting the program. Right-click on this file and select the option called Extract All. Now open folder ShadowExplorerPortable.
In the list of files, find the ShadowExplorerPortable program and run it.
The main program window will open before you, as in the following example. The main window is divided into two parts – left and right. In the left part of the window, select the drive on which the encrypted files are located and select the date closest to the moment when the virus attacks your computer, encrypts the files and has changed the file extension to .bbnm. In the right part of the window, select the file you want to restore, then right-click on it.
A small pop-up menu will open before you, select Export in it. In the next window, select the directory where the recovered files will be saved.
What else do I want to say about the process of recovering encrypted files using the ShadowExplorer tool. Unfortunately, very often ransomware disable the Windows Previous Versions function and delete all saved copies of files. Therefore, after starting the ShadowExplorer, you may find that it is impossible to recover files. In this case, use another method of recovering encrypted .bbnm files, which is given below.
Restore .bbnm files using PhotoRec
Another way to recover encrypted .bbnm files is the ability to use utilities designed to find and recover accidentally deleted and lost data. We recommend that you use the free PhotoRec tool. It is one of the best and has already helped readers of our site repeatedly recover encrypted files in a seemingly absolutely hopeless situation.
Before using the program, you need to download it. Use the link below.
When the file is downloaded, in the folder where you saved it you will see a file with the name ‘testdisk-7.0.win_.zip’. This file is the archive that contains the PhotoRec. To use the PhotoRec, this archive must be unzipped. Right-click on the file and select the item called Extract All. Open the folder with the name testdisk-7.0, you will see a list of files similar to the one below.
In the contents of the directory that opens, find the file with the name QPhotoRec_Win and run it. You will be shown a window similar to the one in the following figure. This is the main PhotoRec window.
Here you need to select the physical disk and the disk partition (disk name) where the encrypted .bbnm files are located. Note that in section ‘File System Type’, option ‘FAT/NTFS’ must be selected. Now select the folder where the recovered files will be written. We recommend using a partition or drive that does not contain encrypted files. It is better to use external media. It is very important! Since the PhotoRec restores files that were deleted by the Windows OS, if you restore them to the same drive on which you are trying to find them, a situation may occur when the Windows simply physically overwrites them and you can no longer recover such files.
Next, at the bottom of the window, click File Formats. A small window opens that lists the types of files that the PhotoRec can find and restore.
Leave only those file types that you need to recover selected. For example, if you want to restore images of ‘jpg’ format, then select the file type ‘jpg’. Having decided which files to recover, click OK button.
Having completed the steps listed above, you have made all the settings necessary to search and restore encrypted .bbnm files. It remains only to click on the Search button. The process of searching and restoring files can take a very long time, be sure not to turn off the computer or restart it. During this process, the program will show the current search location (disk sector), how many and which files were found and restored.
When the file recovery process is complete, click the Quit button. Then open the directory that you previously selected as the place where the recovered files will be written.
Here you will see one or more directories with the name recup_dir (recup_dir.1, recup_dir.2, …). Check these folder to find the files you need. The file name may not be restored, so to find what you need, use file sorting, as well as the standard Windows OS search by file contents.
