What is Mnbzr file
The .Mnbzr extension is a file extension that is used by the Mnbzr ransomware belonging to the Crysis/Dharma family to mark files that have been encrypted. Mnbzr ransomware is a malicious program that encrypts user files and demands a ransom for a key-decryptor pair that is necessary to decrypt the affected files. It uses a strong encryption system and a long key, which virtually eliminates the possibility of decrypting files without a key. Files encrypted with .Mnbzr extension become useless, their contents cannot be read without the key that the criminals have.
Text presented in the Mnbzr ransomware pop-up:
YOUR FILES ARE ENCRYPTED
Don’t worry,you can return all your files!
If you want to restore them, follow this link:email email@example.com YOUR ID xxxxxxxxxxxx
If you have not been answered via the link within 12 hours, write to us by e-mail:firstname.lastname@example.org
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
What is Mnbzr ransomware
Mnbzr ransomware is one of the variants of Dharma/Crysis ransomware. The most common source of infection is cracked apps and games, torrents files, freeware, Windows and Microsoft Office activators, and other similar software. Upon execution, it encrypts files using a key that is individual for each computer. Mnbzr uses a very strong encryption system, which eliminates the possibility of determining the key, even using a super computer. The encryption process is very fast, regardless of what is in the file, the virus can easily encrypt it. Mnbzr ransomware can encrypt almost all files that are on the computer, including those located on network drives. The only thing that the virus does not encrypt is the files that are necessary for the Windows OS to function normally. Below we list some types of files that can be encrypted by the ransomware:
.upk, .sb, .xf, .ztmp, .y, .fos, .lrf, .wp7, .t13, .desc, .wpd, .3fr, .txt, .yml, .xls, .3dm, .psk, .wma, .odc, .menu, .itdb, .zip, .wp6, .dng, .ptx, .zw, .wot, .p7b, .erf, .xxx, .big, .mdbackup, .odt, .fpk, .qic, .docm, .ff, .wire, .ppt, .xbplate, .crw, .wgz, .wmv, .esm, .forge, .blob, .3ds, .wbk, .hvpl, .zabw, .x3f, .svg, .rim, .orf, .dazip, .rofl, .sid, .wbd, .bc7, .xlsx, .pptx, .ltx, .wp, .flv, .xmmap, .kf, .0, .wps, .mcmeta, .xlsm, .psd, .sidn, .m3u, .nrw, .xpm, .dba, .odb, .indd, .pkpass, .bkf, .xlgc, .wma, .das, .accdb, .wotreplay, .wav, .ods, .mlx, .kdb, .wsc, .xwp, .z3d, .1st, .pdf, .dwg, .bkp, .ysp, .xlsb, .x, .itl, .wdb, .wpb, .lbf, .z, .xar, .bc6, .wb2, .xlsx, .srw, .wps, .py, .pdd, .wp4, .rtf, .sav, .map, .sr2, .wp5, .mef, .wm, .xx, .sidd, .wpw, .sie, .xls, .vtf, .dxg, .js, .ibank, .layout, .x3f, .wbmp, .hkx, .d3dbsp, .wmv, .odm, .xdb, .jpe, .jpeg, .wsd, .w3x, .webp, .zdc, .mov, wallet, .xld, .m4a, .xyp, .vdf, .wmd, .p12, .rar, .wpl, .epk, .wmo, .rw2, .arw, .mddata, .png, .wbm, .sql, .vpk, .rgss3a, .wbz, .pptm, .wsh, .mpqge, .xbdoc, .itm, .jpg, .mp4, .xdl, .hplg, .bay, .mdf, .zif, .tax, .dcr, .wpd, .pef, .vpp_pc, .rb, .2bp, .ai, .xml, .ntl, .gdb, .dmp, .raf, .wn, .eps, .qdf, .db0, .slm, .iwd, .ybk, .csv, .cfr, .ws, .rwl, .snx, .iwi, .dbf, .x3d, .arch00, .avi, .fsh, .srf, .cr2
When a file is encrypted, ‘.id-USERID.[EMAIL-ADDRESS].Mnbzr’ is added at the end of its name, that is, if you had a file of ‘document.docx’, then a file with the name ‘document.docx.id-USERID.[email@example.com].mnbzr’ will appear in its place. If you change the file name, just delete the added extension, then nothing will change. The file will remain encrypted, and as before, this file will not be possible to open in the program with which it is associated.
Perhaps you found on your computer or its desktop a new file called ‘FILES ENCRYPTED.txt’, which for some reason is not encrypted. An example of such a file is given below.
Text presented in the FILES ENCRYPTED.txt file:
all your data has been locked us
You want to return?
write email firstname.lastname@example.org
This file is very important, in addition to containing a ransom demand, it also contains information that allows you to contact intruders. According to the message, the victim is invited to contact the attackers using the given email address. In response, the authors of the virus will give a Bitcoin address to which the ransom must be transferred. Of course, you should understand that there is no guarantee that the attackers, after receiving the ransom, will provide you with the key necessary to decrypt your files. In addition, by paying the ransom, you will push attackers to create a new ransomware.

How to decrypt .[firstname.lastname@example.org].mnbzr files
All files with the ‘.Mnbzr’ extension are encrypted. Their contents cannot be unlocked simply by removing this extension or completely changing the filename. Unfortunately, as we already reported in this article, there is currently no way to decrypt files. The reason for this is the complexity of the encryption algorithm that the authors of Mnbzr virus use. In principle, this is what the attackers sought. But this does not mean that you have no choice and you need to pay a ransom for your files.
Never pay the ransom! Every security expert will tell you this over and over. Of course, there is a chance that by paying a ransom, Mnbzr virus authors will allow you to unlock your files, but there is no guarantee. Moreover, you should understand that when you pay a ransom, you unknowingly push the attackers to create new, even more destructive viruses.
Do not forget that besides you, thousands more people around the world have lost their files, that is, you are not alone. Antivirus companies, security experts are working on something that will allow you to decrypt .Mnbzr files. Perhaps in the future an universal method will be developed that will allow all victims to unlock all their data.
Of course, as soon as a way to decrypt the files appears, we will post a message about this to this article or to our facebook account. Therefore, we recommend that you follow the updates.
How to restore .[email@example.com].mnbzr files
As we wrote above, you cannot decrypt files encrypted with Mnbzr ransomware. But you can use a different way, there is a small chance to restore .Mnbzr files without decrypting them. Programs created for searching and recovering lost and deleted data can help you with this. We recommend you to use the following free programs: PhotoRec and ShadowExplorer. Two more things we want to say about. First, before restoring files, you must be 100% sure that there is no ransomware on the computer. We recommend using free malware removal tools that we examined in this article. Second, and what is very important! The less you use your computer after ransomware infection, the higher the chance that you will be able to recover encrypted files.
Use ShadowExplorer to restore .[firstname.lastname@example.org].mnbzr files
First of all, try to recover your files using a free tool called ShadowExplorer. This program will allow you to recover your files from Shadow Volume Copies. These copies are created automatically by the OS when you work with your files. Unfortunately, very often, the virus automatically deletes all these copies and thus prevents the user from recovering encrypted files. Nevertheless, in some cases, the ransomware cannot delete all copies, and the user gets the opportunity to quickly restore all files. Therefore, our opinion, you should definitely try this method!
First, visit the following page, then click the ‘Download’ button in order to download the latest version of ShadowExplorer.

This video step-by-step guide will demonstrate How to recover encrypted files using Shadow Explorer.
Recover .[email@example.com].mnbzr files with PhotoRec
Another really working way to recover your encrypted files is to use a program named PhotoRec. It is created to recover deleted or lost files. Does the Mnbzr ransomware block this method? Fortunately, the ransomware cannot block this method of recovering the contents of encrypted files. The more you used (moved, deleted, modified) files before infection, the greater the chance that you will be able to recover them.
Download PhotoRec on your personal computer from the following link.
