Question

How does the code checksum technique work as an antidebugging measure?

a.

Checksums are precalculated for functions and checked randomly at runtime

b.

Hardware breakpoints are prevented from being set

c.

Code is modified to make it more difficult for reversers to understand the program flow

d.

The program is terminated if a debugger is detected

Answer: (a).Checksums are precalculated for functions and checked randomly at runtime Explanation:Checksums are precalculated for functions within the program, and checked randomly during runtime to detect modifications made by debuggers or code patching.
