Segment of code caller the API will be detected rootkit detector, which takes the return address from the stack. Such a model makes the call, this detection is not possible. In a complex environment is not is acceptable procedural of branching in the module. This is the standard call model AV expect from us

Description is not required, since this is the code. It is very simple.
It should crash, as this PoC. Two addresses are given constant (the gateway as well), these values you have any other. Code to study, not to run.

Here is a working example 2397
