Question

How is the OR operator implemented when reversing code?

a.

Using a single conditional jump

b.

Using a single unconditional jump

c.

Using a conditional jump for each condition and adding a final jump that skips the conditional block if neither conditions are met

d.

Using a reversed conditional jump for each condition and adding a final jump that goes to the code right after the conditional block if the last condition is satisfied

Posted under Reverse Engineering

Answer: (c).Using a conditional jump for each condition and adding a final jump that skips the conditional block if neither conditions are met Explanation:The straightforward approach for implementing the OR operator is to use a conditional jump for each condition (without reversing the conditions) and add a final jump that skips the conditional code block if neither conditions are met.
