Question

What is the main challenge when extracting type information from native IA-32 executables?

a.

The lack of explicit type information in the executables.

b.

The difficulty of identifying calls to known functions.

c.

The complexity of the decompilation process.

d.

The absence of bytecode in the executables.

Posted under Reverse Engineering

Answer: (a).The lack of explicit type information in the executables. Explanation:Native IA-32 executables, like most other processor architectures, do not contain explicit type information. Therefore, extracting type information from these executables can be a challenge.
