• Question 245:

  In the context of password security, a simple dictionary attack involves loading a dictionary file (a text file full of dictionary words) into a cracking application such as L0phtCrack or John the Ripper, and running it against user accounts located by the application. The larger the word and word fragment selection, the more effective the dictionary attack is. The brute force method is the most inclusive, although slow. It usually tries every possible letter and number combination in its automated exploration.

  If you would use both brute force and dictionary methods combined together to have variation of words, what would you call such an attack?

  A. Full Blown

  B. Thorough

  C. Hybrid

  D. BruteDics

  Correct Answer: C

• Question 246:

  A user on your Windows 2000 network has discovered that he can use L0phtcrack to sniff the SMB exchanges which carry user logons. The user is plugged into a hub with 23 other systems. However, he is unable to capture any logons though he knows that other users are logging in.

  What do you think is the most likely reason behind this?

  A. There is a NIDS present on that segment.

  B. Kerberos is preventing it.

  C. Windows logons cannot be sniffed.

  D. L0phtcrack only sniffs logons to web servers.

  Correct Answer: B

• Question 247:

  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?

  A. MD4

  B. DES

  C. SHA

  D. SSL

  Correct Answer: B
