312-50V13 Question #119: Real Exam Question with Answer & Explanation

Question

You are attempting to crack LM Manager hashed from Windows 2000 SAM file. You will be using LM Brute force hacking tool for decryption. What encryption algorithm will you be decrypting?

Options

• AMD4
• BDES
• CSHA
• DSSL

Explanation

The Lan Manager (LM) hash, used in older Windows systems like Windows 2000 for storing user passwords, utilizes the DES encryption algorithm.

Common mistakes.

• A. MD4 is the hashing algorithm primarily used for NTLM hashes, which superseded LM hashes but is a different algorithm.
• C. SHA (Secure Hash Algorithm) is a family of cryptographic hash functions, significantly stronger than DES, and was not used for LM hashes.
• D. SSL (Secure Sockets Layer) is a protocol for securing network communications, not a password hashing algorithm.

Concept tested. LM hash algorithm (DES)
