Question

How can code encryption be used in conjunction with antidebugger techniques?

a.

Code encryption makes it impossible to automatically unpack the encrypted executable.

b.

Code encryption makes it easier to run the program inside a debugger.

c.

Code encryption eliminates the need for antidebugger tricks.

d.

Code encryption has no effect on antidebugger techniques.

Posted under Reverse Engineering

Answer: (a).Code encryption makes it impossible to automatically unpack the encrypted executable. Explanation:Encrypting the program forces reversers to run it inside a debugger in order to allow the program to decrypt itself, making it more difficult to reverse engineer.
