Actual exam question from ECCouncil's 312-49v10
Question #: 147
Topic #: 1
[All 312-49v10 Questions]

You are the network administrator for a small bank in Dallas, Texas. To ensure network security, you enact a security policy that requires all users to have 14 character passwords. After giving your users 2 weeks notice, you change the Group Policy to force 14 character passwords. A week later you dump the SAM database from the standalone server and run a password-cracking tool against it. Over 99% of the passwords are broken within an hour. Why were these passwords cracked so Quickly?

  • A. Passwords of 14 characters or less are broken up into two 7-character hashes
  • B. A password Group Policy change takes at least 3 weeks to completely replicate throughout a network
  • C. Networks using Active Directory never use SAM databases so the SAM database pulled was empty
  • D. The passwords that were cracked are local accounts on the Domain Controller

Selected Answer: A
A. Passwords of 14 characters or less are broken up into two 7-character hashes: Correct Windows' LAN Manager (LM) hashing splits passwords into two 7-character blocks, making them easier to crack with brute force or rainbow table attacks.

Correct Answer: A. Passwords of 14 characters or less are broken up into two 7-character hashes Explanation: On Windows systems, passwords of 14 characters or less are split into two separate 7-character hashes when stored using the LAN Manager (LM) hash algorithm, which is an outdated and less secure hashing method. Here’s why this matters:

Selected Answer: A
The most plausible reason the passwords were cracked so quickly is related to the way Windows stores and handles passwords, particularly with older hashing methods like LAN Manager (LM) hashes. LM hashes are known to split passwords into two 7-character chunks and hash them separately, which makes them much easier to crack than a single 14-character hash

A is the correct answer. No domain controller in this question. Domain Controllers don't keep passwords in the SAM file. This is all about LM an NTLM passwords. The weakness is called 7 & 7.

Selected Answer: D
The passwords were cracked quickly because they were local accounts on the Domain Controller, which typically have weaker security measures compared to domain accounts.
