What is Bpsm Ransomware

Bpsm is a ransomware infection belonging to the Djvu/STOP Ransomware family. This family has released a number of file encryptors that target various users worldwide. Once the system is penetrated by ransomware, the virus begins scouting for potentially valuable file formats and running data encryption. After the cryptographic encryption occurs, users will no longer be able to access and use their data as before. You may immediately spot the change by looking at the altered names of the files. This specific ransomware assigns the .bpsm extension, making a file like 1.pdf change to 1.pdf.bpsm and reset its original icon. Usually, Bpsm Ransomware and other modern Djvu/STOP versions generate “online” keys, which means full decryption of data is likely impossible without the help of cybercriminals. There are, however, sometimes exceptions to this – which can be found about further below.

Following successful encryption, the virus drops a text note called _readme.txt with decryption guidelines inside. They instruct victims to contact extortionists via e-mail and pay a ransom of 490$ or 980$ (in case no contact is made within 72 hours). In addition, victims can also send 1 encrypted file (without valuable information) and get it fully decrypted for free. This “promotion scheme” is widely-used by many cybercriminals to prove their decryption abilities and incline victims towards paying the ransom. After the payment is made, threat actors promise to send a unique decryption key and compatible software for its application. Unfortunately and as was mentioned earlier, cybercriminals are usually the only figures capable of full file decryption. You can give a try to third-party tools in our guide, however, it should be mentioned that such a decryption may not be successful if data exchange with the ransomware’s command server was established correctly and generated an online key. Opposite to offline keys, online keys are unique for each victim, which is the main reason, making decryption practically impossible without original developers. While some older STOP/Djvu versions can be officially decrypted, Bpsm Ransomware is less likely to fall under this category. As of now, the only two ways victims can recover their data are either to pay cybercriminals or recover files from an available backup. Backups are copies of files stored on external storage (e.g., cloud, USB pen drives, etc.) that were not affected at the time of infection. Recovering data from backups is always a safer and preferred option, as many cybercriminals tend to fool their victims and not send any decryption keys/tools eventually. Before trying to restore data without the involvement of cybercriminals, it is essential to remove the infection from your computer – thus, prevent its malicious activity. Read carefully our guide below to do so and explore various recovery alternatives to return your files.

How Bpsm Ransomware infected your computer

The most common distribution vectors used by various ransomware are e-mail spam letters, trojans, deceptive third-party downloads, pirated/cracked downloads, fake software cracking tools, fake software updates/installers, backdoors, keyloggers, botnets, system exploits, and other dubious channels as well. The most typical infection scenario is when inexperienced users get tricked into opening some malicious content (e.g., attachments or links). Quite often ransomware is disguised as some legitimate file (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS extensions) and distributed through e-mail letters. Such letters usually imitate names of legal companies/entities (e.g., delivery companies, tax authorities, banks, and so forth). Cybercriminals largely benefit from click-bait titles, whick make inexpreicned or excessively curious users open the malicious attachment or link. As a result, the contained infection start its malicious code to get installed onto the targeted system. To prevent such and similar drive-by (stealth) installations of malware, you should avoid downloading software from unofficial resources (Peer-to-Peer websites, torrent pages, landing pages, etc.) and beware of opening content that looks suspicious. Read our guide below and learn how one can protect his PC against threats like ransomware (and other possible malware) in the future.

Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. Bpsm Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.

fake windows update from Bpsm Ransomware

It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Bpsm Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. The virus assigns a certain ID to the victims, which is used to name those files and supposedly to send a decryption key. Great tools to protect against Bpsm Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.
