What happens to the computational cost for an attacker when a cryptographic hash function loses its second preimage resistance?

A)Increases to factorial complexity
B)Becomes less than brute-force
C)Remains at exponential complexity
D)Approaches near-zero computational cost

💡 Explanation

If second preimage resistance fails, finding a different input that produces the same hash becomes easier than brute-force, because the attacker can exploit the weaknesses in the hashing algorithm; therefore, the computational cost decreases, rather than remaining high.
