BPSM Virus Files [.bpsm File] – Remove + Decrypt

What Is Bpsm Virus?

Bpsm virus is a type of malicious software (ransomware) that infects computers and encrypts files, making them inaccessible until the user pays a ransom to the cybercriminals. It is typically spread through phishing emails, malicious links, and exploit kits. It targets Windows systems and spreads through a network of compromised machines. This virus uses the _readme.txt note and the .bpsm file extension for encryption.

Read this article to learn more about it and how you can remove it and fix your files.

Bpsm Virus – Why Is My Windows Infected?

Bpsm ransomware is a type of malicious software that infects Windows systems using obfuscators and encrypts files, making them inaccessible. It then demands a ransom payment from the user in exchange for a decryption key to unlock the encrypted files. It is important to note that paying the ransom does not guarantee that the files will be unlocked, and it is not recommended to do so.

Bpsm Virus – How Did I Get Infected?

Two main ways exist which cause an infection with the Bpsm virus:

  • If it is sent to you as an e-mail attachment or a URL.
  • By being downloaded from a shady site.

Bpsm ransomware is typically spread through malicious email attachments, malicious websites, and software downloads from unverified sites. It can even be spread through legitimate websites that have been hacked.

Bpsm Virus – What Does It Do?

Bpsm Ransomware is a malicious virus that encrypts all of the files on the infected computer and then demands a ransom in exchange for the decryption key. The virus also changes the file extensions of the encrypted files to “.bpws”. Its malicious files may exist in the following directories of Windows:

  • %Local%
  • %Temp%
  • %Windows%
  • %SystemDrive%
  • %LocalLow%
  • %AppData%
  • %System%
  • %system32%

The Bpws Ransomware virus also adds a file named “_readme.txt” to each folder with an encrypted file that contains instructions on how to pay the ransom and decrypt the files.

The virus may also createe value entries in the Run and RunOnce Windows Registries, that have the following location:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

What Are .bpws Files

The .bpws encrypted files are files that have been encrypted using the AES encryption algorithm. This encryption method is designed to keep files secure and private by using a combination of symmetric-key algorithms and public-key cryptography. The virus may attack the following files to encrypt them:

  • Videos (.mp4, .avi, etc.).
  • Audio (.mp3, .wav, etc.).
  • Picture file kinds (.jpg, .png, .etc).
  • Archive file formats (.zip, .rar, etc).
  • Documents of different types (.docx, .pptx, etc.).
  • Others.

The files may look like shown in the example image below:

How to Open .bpsm Files

There is no guaranteed way to open .bpsm virus encrypted files without a decryption key. However, you can try to use a data recovery software or system backup to recover your files, as the ransomware may not have completely destroyed the original files. Additionally, you can contact the ransomware authors, if they provide a free decryption key, or you can purchase a decryption key from them – something which is not reccommended.

What To Do If My Files Are .bpsw?

The best way to deal with this ransomware attack is to remove the malicious software from your computer and restore your .bpws files from a backup. If you do not have a backup, then you may be able to use a reputable decryption tool to try to decrypt your files.

However, since DJVU is a relatively new ransomware, there is currently no free tool available for cracking its cipher, unless your decryption key is offline.
