What is Bpsm virus?
Bpsm virus is a ransomware that encrypts files such as videos, documents and demands ransom from users to decrypt their files. Bpsm uses a strong encryption algorithm to encrypt files on fixed, removable, and network drives, renames the files by appending the .bpsm extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “document.docx” will be renamed to “document.docx.bpsm”, a “image.jpg” file to “image.jpg.bpsm”, “invoice.pdf” to “invoice.pdf.bpsm”, and so on.

Bpsm ransomware in detail
Bpsm ransomware is a new variant of the STOP (djvu) ransomware. It infects the computer when the user downloads or runs malware infected files. Criminals lure unwary users into downloading ransomware by hiding malicious code within cracked versions of paid software, torrents, free software, key generators, and so on. Upon execution, an instance of Bpsm virus is installed on victim’s computer.
Once installed on a computer, Bpsm ransomware 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. 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’), 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’).
The Bpsm ransomware virus encrypts files using a strong encryption algorithm and a key (‘offline key’ or ‘online key’, as described above). It 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. Bpsm 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 .ini, .bat, .dll, .lnk, .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:
.ibank, .vfs0, .wmv, .pkpass, .sie, .menu, .jpeg, .wpg, .p7b, .docm, .iwi, .wotreplay, .p12, .wbz, .wsc, .m4a, .sis, .ncf, .esm, .gdb, .wm, .t13, .ods, .wp5, .wp7, .zdb, .srf, .1, .desc, .odc, .zabw, .wbc, .0, .eps, .doc, .db0, .wpb, .ptx, .sb, .mdf, .sidd, .wbmp, .raf, .r3d, .bar, .xf, .dba, .rtf, .wbm, .upk, .z, .zi, .mlx, .cdr, .csv, .icxs, .xbplate, .das, .mov, .hkx, .3ds, .bsa, .arw, .rim, .d3dbsp, .x3d, .vpp_pc, .xyw, .wma, .rw2, .mef, .3fr, .pfx, .xwp, .yal, .ai, .p7c, .bc6, .flv, .m3u, .cfr, .xyp, .wri, .wgz, .y, .pptx, .dbf, .cr2, .w3x, .vdf, .svg, .wmv, .ntl, .t12, .xml, .xlsb, .apk, .lvl, .sql, .wpd, .hplg, .wmo, .xlsm, .7z, .wpw, .xls, .webp, .wdb, .rwl, .kdc, .wmd, .png, .wcf, .mpqge, .erf, .wsd, .xxx, .mdb, .jpg, .xy3, .wbd, .ltx, .mdbackup, .arch00, .bay, .zif, .wpl, .xdb, .odp, .z3d, .py, .litemod, .yml, .layout, .webdoc, .tax, .wpd, .ybk, .avi, .iwd, .hkdb, .psd, .x3f, .ppt, .mrwref, .cas, .crt, .m2, .kdb, .xlsx, .blob, .xx, .mcmeta, .der, .xls, .wpa, .zdc, .gho, .xld, wallet, .jpe, .dazip, .mp4, .dng, .xlgc, .wps, .qic, .zw, .wire, .big, .sav, .js, .wp4, .vpk, .xbdoc, .kf, .qdf, .pst, .dcr, .lbf, .forge, .tor, .bkf, .ztmp, .docx, .bik, .itm, .crw, .vtf, .sidn, .xlk, .rb, .xmind, .3dm, .pef, .accdb, .wps, .dxg, .snx, .wpe, .wp, .wb2, .sid, .sr2, .txt, .itdb, .wpt, .vcf, .psk, .xpm, .2bp, .xmmap, .epk, .wmf, .ysp, .raw, .srw, .pdf, .x, .wma, .re4, .wp6, .odm, .wav, .fos, .zip, .rofl, .wbk, .xdl, .ff, .syncdb, .slm, .odt, .fpk, .xlsm, .rgss3a, .hvpl, .mddata, .pdd, .nrw, .dwg, .css, .cer, .xar, .odb, .x3f, .1st, .bc7, .sum, .fsh, .rar, .indd, .pem, .xlsx, .ws, .wn, .lrf, .xll, .bkp, .itl, .orf, .dmp, .pptm, .map, .wsh, .asset, .zip, .wot
The Bpsm ransomware encrypts file-by-file. Each file that has been encrypted will be renamed, the .bpsm 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 the Bpsm authors. An example of the contents of this file is given below.
Screenshot of the contents of ‘_readme.txt’ file (Bpsm ransom note)
This message says that all files on the computer are encrypted and the only way to decrypt them is to purchase a key and a decryptor from the Bpsm authors. 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.
Text presented in the ransomnote:
ATTENTION!
Don’t worry, you can return all your files!

How to remove Bpsm virus (ransomware)
Before you start decrypting or recovering .bpsm files, you need to remove the Bpsm autostart entries. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection.
It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Bpsm ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Bpsm virus, then let us know in the comments, we will try to help you.
To remove Bpsm ransomware, follow the steps below:
Kill Bpsm virus
Press CTRL, ALT, DEL keys together.
Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Bpsm ransomware then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.
It is not difficult to detect a process related to the Bpsm ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Bpsm ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.
Disable Bpsm startup
Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.

How to decrypt .bpsm files
As we already reported above, files with .bpsm extension are files that have been encrypted by the Bpsm ransomware virus. Their contents will remain locked until decrypted using the decryptor and the key. Fortunately, there is a free decryptor that can decrypt .bpsm files. Below we provide instructions on where to download and how to use a free Bpsm File Decrypt Tool.
Free Bpsm File Decrypt Tool (STOP Djvu decryptor)
To decrypt .bpsm files, use Bpsm File Decrypt Tool
- Download Bpsm File Decrypt Tool 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.
Bpsm File Decrypt Tool is a free software that can decrypt the encrypted files only in some cases, when the files were encrypted with an ‘offline key’. If the files were encrypted with an ‘online key’, then they cannot be decrypted. The reason for this is that the decryption key is in the hands of criminals and this key can not be determined. This does not mean that if your files are encrypted with an online key, then their contents are lost forever. Fortunately, there are several ways to recover encrypted files. These methods do not involve the use of decryption and therefore can be used in any case, no matter what key the ransomware used to encrypt files.
How to find out which key was used to encrypt files
Since Bpsm File Decrypt Tool only decrypts files encrypted with an offline key, each Bpsm’s 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.
Personal ID is highlighted here
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 ‘0626’ – 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’, Bpsm 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.
Bpsm File Decrypt Tool : “No key for New Variant online ID”
If, when you try to decrypt .bpsm files, Bpsm File Decrypt Tool reports:
No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible
It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Bpsm authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.
Bpsm File Decrypt Tool : “No key for New Variant offline ID”
If, during decryption of .bpsm files, Bpsm File Decrypt Tool reports:
No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.
It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained 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.
If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .bpsm files.
This video step-by-step guide will demonstrate How to use STOP Djvu decryptor to Decrypt encrypted files.
How to restore .bpsm files
As we mentioned above, in addition to using the Bpsm File Decrypt Tool, 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 ransomware 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 the Bpsm ransomware virus is completely removed. To scan your computer for ransomware, use free malware removal tools.
Restore .bpsm files using Shadow Explorer
The Microsoft Windows has a feature called ‘Shadow Volume Copies’ that can help you to recover .bpsm 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.
ShadowExplorer can be downloaded from the following link. Save it directly to your Windows Desktop.
