I'm not usually in this kind of paper, but this time, I am exceptionally writing a really short one about something related to some VM evasive PoC.
There is always some tricks to detect if you are running on a virtual machine or not. Most of them are stupid, but it's enough accurate to just lose some minds when you have to harden your sandbox.
The idea here, there are some sensors to check the current CPU Power Usage. When you see as below, it returns this kind of values, when you are running a program normally.
But in a sandbox, it will return 0.
