CEH v9 Question of the Week: Password Cracking Tool

CEH-v9-QOWBlack

Johnny is a member of the hacking group Orpheus1. He is currently working on breaking into the Department of Defense’s front end Exchange Server. He was able to get into the server, located in a DMZ, by using an unused service account that had a very weak password that he was able to guess. Johnny wants to crack the administrator password, but does not have a lot of time to crack it. He wants to use a tool that already has the LM hashes computed for all possible permutations of the administrator password.

What tool would be best used to accomplish this?

A. SMBCrack
B. RainbowTables
C. SmurfCrack
D. PSCrack

Reveal Answer

The correct answer is B.

A rainbow table is a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes. Tables are usually used in recovering a plaintext password up to a certain length, consisting of a limited set of characters.
