NATIONAL SECURITY BUREAU Ransomware – Analysis
NATIONAL SECURITY BUREAU is a virus that encrypts your files and opens a ransom note, with instructions inside it, about the compromised computer machine. The extortionists want you to pay a ransom fee for the alleged restoration of your files. According to malware analysis samples, the cryptovirus might be from the Virlock ransomware family.
NATIONAL SECURITY BUREAU 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 start the virus automatically with each boot of the Windows Operating System.
After encryption the NATIONAL SECURITY BUREAU virus shows the following ransom message inside a window screen:
The ransom message states the following:
NATIONAL SECURITY BUREAU NSB
Your computer was automatically blocked. Reason: Pirated software found on this computer.Your computer is now blocked. 02 files have been temporarily blocked on your computer.To regain computer access and restore you are required to pay a fine of 250 USB Blocked files will be permanently removed from your computer if the fine is not paid. The NSB has two ways to pay a fine:
1. You can pay your fine online through BitCoin. Bitcoin is available nationwide. Click the tabs below to find the nearest vendor. Your computer will be unlocked after you make your payment.
2. You can come to your provincial courthouse and pay your fine at the Cashiers window.
your computer will be unlocked within 4-5 working days.
To regain access transfer bitcoins to the following address (click to copy): 198tX7NmLg6o8qcTT2Uv9cSBVzN3oEozpv
After the payment is finalised enter Transfer ID below.
Amount 0.661 BTC
If the fine is not paid, a warrant will be issued for your arrest, which will be forwarded to your local authorities. You will be charged, fined, convicted for up to 5 years.
If you explore that screen further you will see multiple other pages which are meant to educate victims about what is BitCoin and how it can be obtained both virtually and from ATMs.
The note of the NATIONAL SECURITY BUREAU ransomware virus states that your files are encrypted. You are demanded to pay “0.661 BTC” to allegedly restore your files. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted all over again after payment.
NATIONAL SECURITY BUREAU Ransomware – Encryption
The encryption process of the NATIONAL SECURITY BUREAU ransomware rather simple – every file that gets encrypted will become simply unusable. Files will get the .exe extension after being locked. The newly added extension will be added as a secondary one, without changing the original, nor the file name. However, the new files will be regarded as PEs – portable executables.
A list with the targeted extensions of files which are sought to get encrypted is currently unknown. However, if the list becomes available, the article will get updated accordingly.
The files used most by users and which are probably encrypted are from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The NATIONAL SECURITY BUREAU 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 above-stated command is executed that will make the effects of the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If a computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore some files back to their normal state.
