ECCouncil 312-50v13 Question Answer

A penetration tester submits altered ciphertexts to a web server and pays close attention to how the server responds. When the server produces different error messages for certain inputs, the tester starts to infer which inputs result in valid internal processing. Which cryptanalytic method is being used in this scenario?

Exploit padding error feedback to recover data

Compare traffic timing to deduce the key

Flip bits randomly to scramble the decryption

Inspect randomness across multiple sessions
