Question

How do hardware breakpoints differ from software breakpoints?

a.

Hardware breakpoints modify the target program, while software breakpoints don't.

b.

Software breakpoints are managed by the processor, while hardware breakpoints aren't.

c.

Hardware breakpoints don't modify the target program, while software breakpoints do.

d.

None of the above

Posted under Reverse Engineering

Answer: (c).Hardware breakpoints don't modify the target program, while software breakpoints do. Explanation:Hardware breakpoints don't modify anything in the target program—the processor simply knows to break when a specific memory address is accessed. Software breakpoints, on the other hand, usually replace an instruction in the target program with an int 3 instruction.
