Bpws ransomware – what is it?
Bpws malware can correctly be classified as a STOP/Djvu virus family. That type of computer virus is aimed on individuals. This feature supposes that Bpws does not carry any sort of additional malware, which often helps virus of various other families to take control of your PC. Since the majority users do not have anything valuable , there is no need to download other malware that increases the risk of failure of the whole ransomware injection.
The usual signs of Bpws ransomware activity is the appearance of .bpws files in your folders, instead of the document you used to have. The photo.jpg turns into photo.jpg.bpws, report.xlsx – into report.xlsx.bpws and so on. You are not able to prevent this action, as well as can’t open that files – they are ciphered with quite strong cipher.
You can also see different other signs of ransomware activity. Spontaneously disabled Microsoft Defender and inability to open the famous anti-malware forums or web pages, where the malware removal and file decryption guides are posted. You will see how it is conducted in the paragraph below. The malware removal and decryption guide are also available – check below how to remove Bpws ransomware and get the .bpws files back.
How did Bpws ransomware encrypt my files?
After the injection, the Bpws ransomware starts a connection with its command and control server. This server is controlled by malware maintainers – fraudsters who manage the spreading of this ransomware. Another activity which is done by these crooks is answering the emails of sufferers, who wish to get their files back.
The files are encrypted with one of the strongest encryption algorithm – AES-256. The “256” digit in the name of this algo means the power of two – 2^256 for this case. 78-digit number of possible password variations – it is impossible to brute force it. As analysts say, it will take more time than our planet can estimate to exist, even if you make use of the most powerful computer system. In each folder that has the encrypted file(s), Bpws ransomware leaves the _readme.txt file with the following contents:
ATTENTION! Don't worry, you can return all your files! All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key.

However, you can still run some of your files. The Bpws malware ciphers only the initial 150 KB of each file, but the other part of this document can be opened. Primarily, it works best with audio/video files, which are surely larger than 150 kilobytes. Not each media player is able to open these files – WinAmp is the best choice, since it is free and well-tested. First seconds of every file will be silent – this part is encrypted – but the rest of the document will be accessible like nothing happened.
Is Bpws ransomware dangerous for my PC?
As it was described several paragraphs before, ransomware is not only about ciphering the files. Bpws ransomware makes the changes in your computer in order to prevent looking for the ransomware removal and file decryption guides. Bpws virus does not create the software barrier – it just modifies the system settings, primarily – networking and security configurations.
Among the networking settings, the most changed item is the HOSTS file. This text file has the DNS-address instructions, which are used by the browsers while sending a request to the server. If you add a specific DNS-address for the certain website, your browser will connect that site through this DNS next time. Ransomware edits that file, adding the unknown DNS, so any of the web browsers will show you the “Unable to resolve the DNS-address” error.
Other modifications done by the virus are aimed at prevention of fast detection of itself, and also disabling the installation of the majority of security tools. Bpws ransomware implements several alterations in Group Policies – the system setting application which allows to change the abilities of each program. In such a way, ransomware blocks the Microsoft Defender and different other anti-malware 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 programs as a primary way of ransomware injection. Under the term of dubious programs I mean programs that are already not supported by the developer and spread through the file sharing websites. These programs may be cracked, to make them usable without purchasing any license. Another example of such a program type is different hacking tools – cheat engines, keygens, Windows activation tools and so on.
These software may be distributed in many methods – through the web page that offers a downloading link, and also through the peer-to-peer networks – ThePirateBay, eMule and so on. All these sources are well-known as the most popular computer piracy resources. People use these sites to get different apps or games for free, even if they must be purchased. No one can prevent the users who crack these apps from adding viruses of some type to the files of the hacked app. Hacktools, meanwhile, are created for outlaw targets, so their developers can easily add the ransomware under the guise of some program element.
These cracked apps, regardless of their source, are one of the most often sources for various viruses, and definitely the most used one for Bpws virus. The best solution is to stop making use of it, and not only because of ransomware installation risks. Avoiding the license purchase is an outlaw action, and both hackers and folks who make use of hacked programs fall under the charge of piracy.
How do I remove Bpws ransomware?
The Bpws virus is extremely hard to wipe out manually. Really, because of the amount of alterations it makes into your system, it is almost unreal to spot them all and repair. The best decision is to make use of anti-malware programs. But which one to choose?
You can read the advices to make use of Microsoft Defender, that is already inside of your computer. But as it was mentioned earlier, most of STOP/Djvu virus examples stop it even before the encryption procedure. Using the third-party tool is the only solution – and I can recommend you the GridinSoft Anti-Malware as an option for that case. It has perfect detection abilities, so the Bpws ransomware will not be missed. It is also capable of system recovery, which is heavily needed after the Bpws virus attack.
To remove Bpws malware infections, scan your computer with legitimate antivirus software.
After the ransomware removal, you can go to file decryption. Ransomware removal is needed to prevent the repeating encryption of your files: while Bpws ransomware is active, it will not miss any unencrypted file.
How to decrypt the .bpws files?
There are two ways to decrypt your files after a Bpws virus attack. First one and the most obvious is file decryption. It is conducted with a special app, designed by Emsisoft, and called Emsisoft Decryptor for STOP/Djvu. This program is free. Analysts update its decryption keys databases as often as possible, so you will definitely get your files back, sooner or later.
Another way to get your files back is to try to recover them from your disk drives. Since ransomware deletes them and substitutes with a ciphered copy, the residue of the documents are still stored on the disk. After the deletion, the information about them is removed from the file system, but not from a disk drive. Special programs, 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 some files unintentionally.
Decrypting the .bpws 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 .bpws files with PhotoRec tool
PhotoRec is an open-source tool, which is designed to recover the deleted or lost files from the disk. It checks each disk sector for the residues of deleted files, and then attempts to recover them. That app is able to recover the files of more than 400 different formats. 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 Bpws virus dangerous?
No. Bpws 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, virus creators may publish the rest of the keys when they stop their activity.
✔️Not all of my .bpws 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.
