Question 680
An approved lab shows NTLM network authentication may be accepted without a plaintext password. What observation would best confirm the intended security outcome?
Explanation
Correct Answer
The report identifies weak authentication design without collecting production hashes. This answer directly addresses the described constraint. Reusable password-derived authentication material can be abused in some NTLM flows. Successful validation requires: The report identifies weak authentication design without collecting production hashes.
Incorrect Answers
That approach concerns a different situation: users receive repeated unsolicited MFA push prompts from an unknown source. Repeated prompts may coerce approval of an attacker-initiated sign-in. The required result is that the report identifies weak authentication design without collecting production hashes. The relevant evidence is: The report identifies weak authentication design without collecting production hashes.
That relates to a different issue: A stolen application bearer token allows an API call without further challenge in a lab. Bearer tokens can authorize access for whoever possesses them. That is not a direct remedy for the requested outcome: The report identifies weak authentication design without collecting production hashes. The relevant evidence is: The report identifies weak authentication design without collecting production hashes.
It would address a password audit tests a curated wordlist against approved offline synthetic hashes. The relevant reason in that case is: Dictionary attacks try likely words instead of exhaustive permutations. Here the required success condition is the report identifies weak authentication design without collecting production hashes. The relevant evidence is: The report identifies weak authentication design without collecting production hashes.
