What is Bitpaymer ransomware? And how does it implement its attack?

A new and updated version of BitPaymer ransomware was spotted recently in the wild by security experts. This new variant appends the .LOCK extension to its encrypted files. Like other variants of Bitpaymer, this new variant is designed to lock files in a computer in exchange for a ransom. Aside from the new extension used and ransom note of this new malware strain, it also employs a new encryption algorithm in encrypting files compared to other Bitpaymer variants.

Once it implements its attack, Bitpaymer ransomware will drop its malicious payload which is used to initiate a connection to a remote server. After that, it creates and downloads malicious files and places them in system folders. It also makes entries in the Windows Registry so that it can run automatically whenever you start your computer. It then scans the computer for files with the following extensions:

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

After finding its targeted files, it uses a combination of AES and RSA encryption algorithm to lock files. The AES 256 cipher is used for every file and a combination of 0C0200000C020000 and then finally wrapped with an embedded RSA 4096 cipher. Following data encryption, it releases the file named “HOW_TO_DECRYPT.txt” containing the following content:

“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.

It isn’t known yet if Bitpaymer ransomware deletes the shadow volume copies of the encrypted files. But whether it deletes them or not, paying the ransom shouldn’t be part of your options to recover your files. There are other alternative ways you can try to restore them without having to pay a cent. But before file recovery, you must eliminate Bitpaymer ransomware from your computer first.

How does Bitpaymer ransomware proliferate?

Bitpaymer ransomware proliferates using spam emails. Crooks usually disguise emails that contain malicious attachments so that users won’t be the wiser. Thus, you need to double check emails first before you open an attachment just to be safe.

  • %WINDIR%\System32\Tasks
  • %APPDATA%\Microsoft\Windows\Templates\
  • %USERPROFILE%\Downloads
  • %USERPROFILE%\Desktop

Step 8: Close the File Explorer.

Before you proceed to the next steps below, make sure that you are tech savvy enough to the point where you know exactly how to use and navigate your computer’s Registry.
