Another ransomware is on the loose and is currently wreaking havoc recently. It is called the Master ransomware. Master ransomware is a malicious program developed by a group of cyber criminals who specializes on ransomware. It is called Master ransomware based on the extensions it appends to the encrypted files. It uses specific encryption algorithm with a public key to modify the files by distorting their structures. After the encryption process is completed, the ransomware creates a decryption key and keeps it. The Master ransomware is known to use the following extensions in marking the encrypted files: [BM-NBM1DiE52wgzUUnzcRPwjMjPEcV4qfpr@bitmessage.ch].master, .[help@onyon.info].master and .[niga@westcost.xyz].master. Once the encryption is done, the ransomware releases a !#_RESTORE_FILES_#!.inf file on your desktop. The file contains the following message:

[WHAT HAPPENED]

Your important files produced on this computer have been encrypted due to a security problem

If you want to restore them, write us to the email: BM-NBM1DiE52wgzUUnzcRPwjMjPEcV4qfpr@bitmessage.ch or makedonskiy@gmx.com

You have to pay for decryption in Bitcoins. The price depends on how fast you write to us.”

Even if you delete the ransom note:!#_RESTORE_FILES_#!.inf file, the Master ransomware is programmed to create a Windows Registry entry that would open the ransom note automatically even if you managed to remove the threat from your computer. Apart from the Windows Registry entry and ransom note, there should be another file related to the Master ransomware, it could be an executable file you have downloaded and executed resulting to the Master ransomware infiltrating your computer system.

Master ransomware is one of the most dangerous ransomware there is.

You may find this bizarre, but one of the worst things you can do is to restart your computer after your computer is infected. Why? Because according to researchers, the Master ransomware might be programmed to destruct some part of your computer system’s data if you reboot your computer. So as an effect, your computer might not be able to boot anymore. So it is important to keep this on your mind: don’t do anything rash like rebooting your computer and do some research first.

If you are not quite sure if the Master ransomware is the culprit that infected your computer, you should check the damaged files first. If it is Master ransomware, your encrypted files should have an appended extension called .master, example, image.jpg.master or report.docx.master, etc. The ransomware encrypts your computer’s files using a secure cryptosystem to make it unusable and to take it as hostage demanding ransom. As mentioned, never make any rash decisions or actions such as giving in to the cyber criminal’s demand to pay the ransom. It is one of the worst things you can do. Paying the ransom does not mean you will get the decryption key and recover your files. Cyber criminals are called cyber criminals for a reason. They are not to be trusted. And besides, paying the ransom could put your security even more at risk since you will be providing your credit card details when paying the ransom through BitCoins. To recover your files, you could employ copies from other storage media, that is, if you have made a backup for all your important files.
