Bbii malware – what is it?
Bbii malware can correctly be classified as a STOP/Djvu malware family. That type of virus is aimed on individuals. This specification supposes that Bbii does not bring any type of additional viruses, which sometimes helps ransomware of various other families to take control of your system. Because of the fact that most users do not have anything valuable , there is no reason to inject additional malware that increases the risk of failure of the whole ransomware operation.
The usual signs of that virus activity is the emersion of .bbii files in your folders, instead of the files you used to have. The photo.jpg turns into photo.jpg.bbii, report.xlsx – into report.xlsx.bbii and so on. You cannot to stop this action, and can’t open that files – they are encrypted with pretty strong cipher.
You can also spectate different other signs of malware activity. Abruptly suspended Microsoft Defender and inability to check the famous anti-malware forums or websites, where the malware removal and file decryption guides are published. You will see how it is conducted in the paragraph below. The malware removal and decryption guide are also available – check below how to delete Bbii ransomware and get the .bbii files back.
How did Bbii ransomware encrypt my files?
After the malware injection, the Bbii ransomware establishes a connection with its command and control server. This server is controlled by malware maintainers – fraudsters who manage the distribution of this ransomware. Another activity which is done by those crooks is answering the emails of sufferers, who intend to get their files back.
The files are ciphered with one of the strongest encryption algorithm – AES-256. The digit in the name of this algorithms means the power of two – 2^256 for this case. 78-digit number of possible decryption keys variations – it is not real to brute force it. As analysts say, it will take more time than our planet can estimate to exist, even in case if you make use of the most powerful computers. In each folder that keeps the encrypted documents, Bbii virus leaves the _readme.txt file with the following contents:

Nonetheless, you can still open some of your files. The Bbii virus encrypts only the initial 150 KB of each file, but the other piece of this file can be opened. Primarily, it works best with audio/video files, which are definitely bigger than 150 kilobytes. Not each media player can open these files – WinAmp is the best option, since it is free and well-tested. First seconds of each recording will be missing – this part is encrypted – but the rest of the document will be accessible like nothing happened.
Is Bbii ransomware dangerous for my PC?
As it was mentioned several paragraphs above, ransomware is not only about encrypting the files. Bbii virus makes the changes in your OS in order to prevent looking for the ransomware removal and file decryption guides. Malware does not establish the software obstacle – it just modifies the settings, primarily – networking and security configurations.
Through the networking configurations, the most changed item is the HOSTS configuration file. This text file has the DNS-address configurations, which are used by the browsers while sending a request to the website server. If you add a specific DNS-address for the certain web page, your web browser will connect that page through this DNS next time. Ransomware edits that file, adding the non-existent DNS, so any of the web browsers will show you the “Unable to resolve the DNS-address” error.
Other changes done by the ransomware are targeted on prevention of fast detection of itself, and also blocking the installation of the majority of anti-malware programs. Bbii ransomware implements some alterations in Group Policies – the system configuration interface which allows to modify the abilities of each application. In such a way, malware stops the Microsoft Defender and various other antivirus programs, and also prevents the launch of antivirus installation files.
How did I get infected?
Throughout the whole term while STOP/Djvu family existed, it was using questionable applications as the main method of ransomware injection. Under the term of questionable software I mean applications that are already not supported by the creator and distributed through the file sharing websites. These programs may be hacked, to make them possible to use without purchasing any license. Another example of such a program type is different hacking tools – cheat engines, keygens, Windows activation tools and so on.
This kind of software may be distributed in many ways – through the site that offers a downloading link, or through the peer-to-peer networks – ThePirateBay, eMule and so on. All these sources are well-known as the most popular computer piracy websites. Folks use these sites to get different apps or games for free, even if these programs must be purchased. No one can stop the users who crack these programs from adding malware of some type to the files of the hacked app. Hacktools, however, are created for outlaw targets, so their developers may easily add the virus under the guise of some program part.
These hacked programs, regardless of their source, are one of the most often sources for various malware, and 100% the most popular one for Bbii malware. The best solution is to avoid making use of it, and not only because of virus installation risks. Avoiding the license purchase is an outlaw action, and both hackers and folks who make use of hacked apps fall under the charge of piracy.
How do I remove Bbii virus?
The Bbii virus is really hard to remove manually. In fact, because of the amount of modifications it makes into your system, it is almost unreal to find them all and fix. The best option is to make use of anti-malware software. But which one to choose?
You may read the advices to make use of Microsoft Defender, that is already in your Windows. However, as it was mentioned earlier, most of STOP/Djvu virus examples disable it even before the ciphering procedure. Using the third-party program is the only possible option – and I can offer you the GridinSoft Anti-Malware as a solution for this case. It has perfect detection abilities, so the virus will not be missed. It is also capable of system repairing, which is heavily needed after the Bbii virus attack.
To remove Bbii malware infections, scan your computer with legitimate antivirus software.
After the ransomware removal, you can go to file decryption. Virus removal is needed to prevent the repeating encryption of your files: while Bbii ransomware is active, it will not miss any unencrypted file.
How to decrypt the .bbii files?
There are two ways to recover your files after a Bbii ransomware attack. First one and the most obvious is file decryption. It is performed with a special tool, designed by Emsisoft, and named Emsisoft Decryptor for STOP/Djvu. This program is absolutely free. Analysts update its decryption keys databases as often as possible, so you will definitely get your files back, sooner or later.
Another option to get your documents and photos back is to try to recover them from your physical disks. Since Bbii virus deletes them and substitutes with an encrypted copy, the residue of the files are still stored on the disk. After the removal, the information about them is wiped from the file system, but not from a disk. Special tools, like PhotoRec, are able to recover these files. It is free, too, and may also be used for file recovery in case when you have deleted a thing unintentionally.
Decrypting the .bbii files with Emsisoft Decrypter for STOP/Djvu
Download and install Emsisoft Decrypter tool. Agree with its EULA and continue to the interface.
The interface of this program is extremely easy. All you have to do is to select the folder where the encrypted files are stored, and wait. If the program has the decryption key which corresponds to your ransomware case – it will decrypt it.
During the use of Emsisoft Decrypter for STOP/Djvu, you may observe various error messages. Don’t worry, that does not mean that you did something wrong or a program does not work properly. Each of these errors refer to a specific case. Here is the explanation:
Error: Unable to decrypt file with ID: [your ID]
The program does not have a corresponding key for your case. You need to wait for some time until the key database will be updated.
No key for new variant online ID: [your ID]
Notice: this ID appears to be an online ID, decryption is impossible.
This error means that your files are encrypted with an online key. In such a case, the decryption key is unique and stored on the remote server, controlled by crooks. Unfortunately, the decryption is impossible.
Result: No key for new variant offline ID: [example ID]
This ID appears to be an offline ID. Decryption may be possible in the future.
Ransomware uses the offline key to encrypt your files. This key is not unique, so you likely have it in common with another victim. Since offline keys must be collected, too, it is important to keep calm and wait until the analysts team finds one which will fit your case.
Remote name could not be resolved
This error indicates that the program has problems with DNS on your computer. That’s a clear sign of malicious alterations in your HOSTS file. Reset it using the official Microsoft guide.
Recovering the .bbii files with PhotoRec tool
PhotoRec is an open-source tool, which is created to recover the deleted or lost files from the disk. It checks each disk sector for the remains of deleted files, and then attempts to recover them. That app is able to recover the files of more than 400 different extensions. Because of the described feature of ransomware encryption mechanism, it is possible to use this tool to get the original, unencrypted files back.
Download PhotoRec from the official website. It is absolutely free, however, its developer warns that he does not guarantee that this program will be 100% effective for file recovery purposes. Moreover, even paid apps can barely give you such a guarantee, because of the chain of random factors that can make the file recovery harder.
Unzip the downloaded archive to the folder you like. Don’t worry because of its name – TestDisk – this is the name of the utility developed by the same company. They decided to spread it together since PhotoRec and TestDisk are often used together. Among the unzipped files, search for qphotorec_win.exe file. Run this executable file.
Before you can start the recovery process, you need to specify several settings. In the drop-down list, choose the logic disk where the files were stored before the encryption.
Then, you need to specify the file formats you need to recover. It may be difficult to scroll all 400+ formats, luckily, they are sorted by alphabetical order.
Finally, name the folder you want to use as a container for recovered files. The program will likely dig out a lot of useless files, which were deleted intentionally, so desktop is a bad solution. The best option is to use the USB-drive.
After these easy manipulations, you may just press the “Search” button (it turns active if you specified all required parameters). The recovery process may take several hours, so keep patient. It is recommended not to use the computer during this term, since you may overwrite some files you are intending to recover.
Frequently Asked Questions
✔️Are the files encrypted by Bbii virus dangerous?
No. Bbii files is not a virus, it is not able to inject its code into the files and force them to execute it. The .EXT files are just the same as regular ones, but encrypted and cannot be opened in the usual way. You may store it together with normal files without any fears.
✔️Is it possible that antivirus software will delete the encrypted files?
As I have mentioned in a previous paragraph, encrypted files are not dangerous. Hence, good anti-malware programs like GridinSoft Anti-Malware will not trigger on them. Meanwhile, some of the “disk cleaning tools” may remove them, stating that they belong to the unknown format and are likely broken.
✔️The Emsisoft tool says my files are encrypted with the online key and cannot be decrypted. What do I need to do?
It is very unpleasant to hear that the files you have are likely lost. Ransomware creators lie a lot in order to scare their victims, but they tell the truth in claims about the strength of the encryption. Your decryption key is stored on their servers, and it is impossible to select it because of the strength of the encryption mechanism.
Try other recovery methods – through the PhotoRec, or using the previously created backups. Search for the previous versions of these files – getting back a part of your dissertation, for example, is better than missing it all.
Last option is just waiting. When the cyber police caughts the crooks who create and distribute ransomware, first get the decryption keys and publish it. Emsisoft analysts will surely take these keys and add them to the Decryptor databases. In some cases, ransomware creators may publish the rest of the keys when they stop their activity.
✔️Not all of my .bbii files are decrypted. What do I need to do?
The situation when the Emsisoft Decryptor failed to decrypt several files usually happens when you have not added the correct file pair for the certain file format. Another case when this problem may appear is when some problem occurred during the decryption process – for example, RAM limit reached. Try to perform the decryption process once again.
Another situation when the Decryptor app may leave your files unencrypted is when ransomware uses different keys for certain files. For example, it may use offline keys for a short period of time when it has connection issues. The Emsisoft tool is not able to check both key types simultaneously, so you need to launch the decryption again, in order to repeat the process.
