Question

What is the disadvantage of embedding this code sequence within a program?

a.

It takes a specific implementation of IsDebuggerPresent API

b.

It requires too much memory

c.

It is too difficult to implement

d.

It causes the program to run slower

Posted under Reverse Engineering

Answer: (a).It takes a specific implementation of IsDebuggerPresent API Explanation:One significant disadvantage of embedding this code sequence within a program is that it takes a specific implementation of IsDebuggerPresent API and assumes that two internal offsets in NT data structure will not change in future releases of the operating system.
