BitPaymer Virus – Infection Spread

BitPaymer ransomware could spread its infection via various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer will become infected. You can see the detections of such a file on the VirusTotal service displayed in a screenshot down below:

BitPaymer ransomware might also distribute its payload file on social media sites and services for file-sharing. Freeware which is found on the Web can be presented as helpful. Also, it could be hiding the malicious script for this cryptovirus. Don’t be opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems suspicious. You should read the tips for preventing ransomware found in our forum section.

BitPaymer Virus – Technical Analysis

BitPaymer is a virus that could encrypt your files and extort you to pay a ransom to get them back to their original state. Malware researchers have discovered multiple malware samples of the virus and have established that it is a newer variant of the BitPaymer family of ransomware viruses with a new method of encryption, and not specifically targeting corporations this time.

BitPaymer ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

The ransom note message that is placed in your computer after encryption and copied for every encrypted file can be seen in the below screenshot:

That ransom note is inside a file called HOW_TO_DECRYPT.txt and reads the following:

Your network has been penetrated.

All files on each host in the network have been encrypted with a strong algorythm.

Backups were either encrypted or deleted or backup disks were formatted.

We exclusively have decryption software for your situation

DO NOT RESET OR SHUTDOWN – files may be damaged.
DO NOT RENAME the encrypted and readme files.
DO NOT MOVE the encrypted and readme files.
DO NOT DELETE readme files.
This may lead to the impossibility of recovery of the certain files.

The note of the BitPaymer ransomware states that your files are encrypted. If you want to get them back, the ransomware threatens that you have to pay up. In case you do any changes to the ransomware’s files or to your own, you are threatened that you will get your data erased, which seems like an empty threat just like the previous Bitpaymer Ransomware Virus variant.

The following two email addresses are used for contacting the cybercriminals directly:


You should NOT under any circumstances pay the ransom. Not only it is huge as a sum, but for a lot less you might find a solution to recover your files. If you pay, your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to cybercriminals is like supporting them and could likely motivate them to create more ransomware viruses and do similar criminal acts.

BitPaymer Virus – Encryption Process

The BitPaymer cryptovirus encrypts various files, but mainly files which have the following extensions:

→.bmp, .jpg, .jpeg, .png, .gif, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .pdf, .mp3

Every single file that gets encrypted will receive an extension appended to it, which is .LOCK. That would be placed as a secondary extension and the ransomware won’t change the original file name and extension of files which it encrypts.

The encryption algorithms used are RSA and AES. An AES-256 key is used for each and every file, then the combination 0C0200000C020000 is added, which is finally wrapped up with by an embedded RSA-4096.

The BitPaymer cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files.
