Question

What is the disadvantage of implementing IsDebuggerPresent intrinsically?

a.

It is easy to detect and bypass

b.

It is difficult to predict what would happen if Microsoft changes one of these data structures in a future release of the operating system

c.

It is not possible in every programming language or development platform

d.

It does not work on user-mode debuggers

Posted under Reverse Engineering

Answer: (b).It is difficult to predict what would happen if Microsoft changes one of these data structures in a future release of the operating system Explanation:The disadvantage of implementing IsDebuggerPresent intrinsically is that it takes a specific implementation of the IsDebuggerPresent API and assumes that two internal offsets in NT data structure will not change in future releases of the operating system.
