M4N1F3STO Ransomware – Technical Analysis

The M4N1F3STO virus is not a cryptovirus, and will not encrypt your files. In spite of that it is still ransomware and features a lockscreen. While your screen is locked, you will not be able to access your computer device.

M4N1F3STO ransomware can create entries in the Windows Registry to achieve perseverance. These registry entries are designed to make the virus launch automatically with each start of the Windows Operating System. In that way, the lockscreen remains and you won’t be able to get past it.

On that lockscreen, there is also a message conveyed. The message includes the instructions and demands of the cybercriminals for unlocking your PC, which also concludes the ransom. You can view the ransom message and that lockscreen just here below:

The ransom note reads the following:

I want to play a game with you. Let me explain the rules:
Your personal files are being deleted. Your photos, videos, documents, etc…
But, don’t worry! It will only happen if you don’t comply.
However I’ve already encrypted your personal files, so you cannot access therm.

Every hour I select some of them to delete permanently,
therefore I won’t be able to access them, either.
Are you familiar with the concept of exponential growth? Let me help you out.
It starts out slowly then increases rapidly.
During the first 24 hour you will only lose a few files,
the second day a few hundred, the third day a few thousand, and so on,

If you turn off your computer or try to close me, when i start the next time
you will het 1000 files deleted as punishment.
Yes you will want me to start next time, since I am the only one that
is capable to decrypt your personal data for you.

Now, let’s start and enjoy our little game together!”
