Bboo file extension
.Bboo file extension is a file extension that uses the 205th version of the STOP ransomware to mark files that have been encrypted by it. Like other ransomware, Bboo virus is a malware that encrypts the victim’s files, and then demands a ransom for decrypting them. Fortunately for the ransomware victims, a team of security researchers created a free decryptor that can decrypt .bboo files. In addition to the free decryptor, there are several alternative methods that allow you to restore .bboo files to their original state (before encryption). Read more about this, as well as how to remove the virus and protect your computer from such ransomware below.
Bboo virus
Bboo virus is new version of STOP (Djvu) ransomware. According to security researchers, this version is not much different from previous versions of STOP ransomware, such as Alka and Repp, which were widespread earlier. The ransomware virus is spread by websites offering to download freeware, key generators, activators, cracked games, torrents and so on.
Upon execution, Bboo creates a folder in the Windows system directory where it places a copy of itself and changes some Windows settings so that it starts up every time the computer is restarted or turned on. The virus collects information about the victim’s computer and then tries to establish a connection with its command server (C&C). If the connection has been established, then it sends information about the infected computer to the server, and in response receives the encryption key (the so-called ‘online key’) and additional commands and malware that must be executed on the victim’s computer. If the virus could not establish a connection with its command server, then it uses a fixed key (the so-called ‘offline key’).
Bboo virus encrypts files using a strong encryption algorithm and a long key (‘offline key’ or ‘online key’, as described above). The virus tries to encrypt as many files as possible, for this it only encrypts the first 154kb of the contents of each file and thus significantly speeds up the encryption process. Bboo has the ability to encrypt files on all drives connected to the computer: internal hard drives, flash USB disks, network storage, and so on. It skips without encryption: files located in the Windows system directories, files with the extension .dll, .lnk, .ini, .bat, .sys and files with the name ‘_readme.txt’. The remaining files located on the victim’s computer can be encrypted. For example, the following file types may be the target of ransomware attack:
.blob, .sid, .vtf, .mdf, .w3x, .syncdb, .srf, .rar, .zw, .slm, .cdr, .bkf, .wsc, .sum, .xyp, .sidn, .mov, .wbmp, .xdb, .xdl, .wpl, .re4, .hkx, .lrf, .mef, .ods, .itdb, .zif, .wire, .dwg, .eps, .zdb, .xbplate, .xbdoc, .odm, .xls, .menu, .asset, .ltx, .webp, .doc, .docm, .p12, .ntl, .1, .jpeg, .xlk, .mpqge, .d3dbsp, .dng, .y, .epk, .z3d, .wpe, .py, .cas, .sr2, .css, .xls, .ncf, .layout, .png, .0, .yal, .desc, .sav, .dbf, .vdf, .forge, .ppt, .gho, .zabw, .big, .csv, .hvpl, .dmp, .wbc, .ybk, .raw, .litemod, .wpw, .psk, .orf, .raf, .wp7, .bik, .iwi, .wpt, .mlx, .3fr, .ibank, .pst, .xmind, .apk, .mrwref, .cfr, .x, .tax, .wbz, .xx, .pdf, .zip, .dba, .wmv, .yml, .x3f, .pkpass, .pak, .icxs, .wpd, .x3f, .dazip, .2bp, .bc6, .vfs0, .upk, .gdb, .wbk, .wot, .wsh, .wdp, .pfx, .pptx, .wpd, .bc7, .hplg, .pptm, .bsa, .wma, .svg, .wmo, .txt, .rw2, .mddata, .wmv, .esm, .wotreplay, .cer, .rwl, .mp4, .lbf, .kdb, .xy3, .indd, .arch00, .der, .dxg, .t13, .ysp, .mcmeta, .xxx, .cr2, .ai, .wm, wallet, .sb, .wgz, .sidd, .wbm, .accdb, .jpe, .t12, .wav, .wp4, .m4a, .wpb, .wma, .odc, .ptx, .ws, .xlgc, .m2, .wb2, .wbd, .rgss3a, .7z, .odt, .mdbackup, .r3d, .snx, .xf, .vcf, .sis, .wps, .itl, .wpg, .pem, .flv, .crt, .hkdb, .psd, .wpa, .js, .xmmap, .webdoc, .wmf, .1st, .wp, .zip, .3ds, .nrw, .qic, .docx, .p7c, .itm, .db0, .wdb, .fsh, .das, .avi, .wsd, .wp5
Bboo encrypts file-by-file. Each file that has been encrypted will be renamed, the .bboo extension will be added at the end of its name. Thus, it marks all encrypted files. In every directory where there is at least one encrypted file, the virus places a file named ‘_readme.txt’. The file contains a message from Bboo authors. An example of the contents of this file is given below.
This message says that all files on the computer are encrypted and the only way to decrypt them is to buy a key and a decryptor from the authors of Bboo virus. That is, criminals demand a ransom for unlocking the victim’s files. The size of the ransom is $980, but if the victim is ready to pay the ransom within 72 hours, then its size is halved to $490. Attackers offer victims to verify that encrypted files can be decrypted. To do this, the victim must send them a small file to one of the email addresses specified in the ‘_readme.txt’ file. Of course, it is obvious that a single decrypted file cannot guarantee that after paying the ransom, the criminals will provide the victim with a working key and decryptor.

How to decrypt .bboo files
As we already reported above, files with .bboo extension are files that have been encrypted by Bboo virus. Their contents will remain locked until decrypted using the decryptor and the key. Fortunately, there is a free decryptor that can decrypt .bboo files. Below we provide instructions on where to download and how to use this decryptor.
To decrypt .bboo files, use free STOP (bboo) decryptor
- Download STOP (bboo) decryptor from the following link.
STOP Djvu decryptor - Scroll down to ‘New Djvu ransomware’ section.
- Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
- Run decrypt_STOPDjvu.exe, read the license terms and instructions.
- On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
- Click the ‘Decrypt’ button.
Unfortunately, at the moment, this decryptor is able to decrypt only files encrypted with an offline key, as Emsisoft found a way to identify this key. Files encrypted with an online key cannot yet be decrypted. The online key is unique to each infected computer, and at the moment there is no way to find this key. Of course, the authors of Bboo virus own this key, but we do not think that paying a ransom is the right way to decrypt .bboo files. In the case when the files are encrypted with an online key, there is a chance to restore the encrypted files using alternative methods, which are described below.
How to find out which key was used to encrypt files
Since Bboo decryptor only decrypts files encrypted with the offline key, each virus victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them.
Find out the type of key using ‘_readme.txt’ file
- Open the ransom demand message (‘_readme.txt’ file).
- Scroll down to the end of the file.
- There you will see a line with the text ‘Your personal ID’.
- Below is a line of characters that starts with ‘0205’ – this is your personal id.
Find out the type of key using ‘PersonalID.txt’ file
- Open disk C.
- Open directory ‘SystemID’.
- Open file named ‘PersonalID.txt’. This file lists “Personal ID”s that match the keys that the virus used to encrypt files.
The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Bboo virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.
If STOP (Bboo) decryptor displays message “Error: Unable to decrypt file with ID”, then two cases are possible why this happens:
- bboo files are encrypted with an ‘online key’, in this case, you need to use alternative methods to restore the contents of encrypted files;
- bboo files are encrypted with an ‘offline key’, but the key itself has not yet been found by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data;
Bboo file recovery
As we mentioned above, in addition to using the free Bboo decryptor, there are several more methods for recovering encrypted files. These methods do not require the use of a decryptor and a key, and therefore are suitable for all cases when the virus used an online key, and for the case when the virus used an offline key. It is very important to check your computer for malware before you try to recover encrypted files. You must be 100% sure that Bboo virus is completely removed. To scan your computer for ransomware, use free malware removal tools.
Use ShadowExplorer to restore .bboo files
The Microsoft Windows has a feature called ‘Shadow Volume Copies’ that can help you to recover .bboo files encrypted by the ransomware. A small tool called ShadowExplorer will allow you to easily access the Shadow copies and restore the encrypted files to their original state. Unfortunately, the ransomware can delete these Shadow copies before it starts encrypting files. Therefore, if ShadowExplorer did not help you, then try another method, which is given below.
Click the following link to download ShadowExplorer. Save it on your Microsoft Windows desktop.

On right panel navigate to the file (folder) you wish to restore. Right-click to the file or folder and click the Export button as displayed on the screen below.
And finally, specify a directory (your Desktop) to save the shadow copy of encrypted file and click ‘OK’ button.
Use PhotoRec to restore .bboo files
The last chance to restore .bboo files to their original state is using data recovery tools. We recommend a program called PhotoRec. It has all the necessary functions to restore the contents of encrypted files. It helped many victims recover data when it seemed like there was no more hope.
Download PhotoRec on your machine by clicking on the following link.
Once downloading is complete, open a directory in which you saved it. Right click to testdisk-7.0.win and select Extract all. Follow the prompts. Next please open the testdisk-7.0 folder similar to the one below.

Select a drive to recover as displayed in the figure below.
You will see a list of available partitions. Choose a partition that holds encrypted files as shown on the image below.
Click File Formats button and select file types to restore. You can to enable or disable the recovery of certain file types. When this is done, press OK button.
Next, press Browse button to select where restored files should be written, then click Search.
Count of recovered files is updated in real time. All recovered photos, documents and music are written in a folder that you have selected on the previous step. You can to access the files even if the restore process is not finished.
When the restore is done, click on Quit button. Next, open the directory where recovered photos, documents and music are stored. You will see a contents as displayed on the screen below.
All recovered documents, photos and music are written in recup_dir.1, recup_dir.2 … sub-directories. If you’re looking for a specific file, then you can to sort your restored files by extension and/or date/time.
How to protect your computer from Bboo ransomware
Most antivirus apps already have built-in protection system against the crypto virus. Therefore, if your computer does not have an antivirus application, make sure you install it. As an extra protection, run the HitmanPro.Alert. HitmanPro.Alert is a small security utility. It can check the system integrity and alerts you when critical system functions are affected by malware. HitmanPro.Alert can detect, remove, and reverse ransomware effects.
Visit the page linked below to download HitmanPro.Alert. Save it on your MS Windows desktop.
When the download is complete, open the folder in which you saved it. You will see an icon like below.
