Hampton is the senior security analyst for the city of Columbus in Ohio. His primary responsibility
is to ensure that all physical and logical aspects of the city’s computer network are secure from all
angles. Bill is an IT technician that works with Hampton in the same IT department. Bill’s primary
responsibility is to keep PC’s and servers up to date and to keep track of all the agency laptops
that the company owns and lends out to its employees. After Bill setup a wireless network for the
agency, Hampton made sure that everything was secure. He instituted encryption, rotating keys,
turned off SSID broadcasting, and enabled MAC filtering. According to agency policy, only
company laptops are allowed to use the wireless network, so Hampton entered all the MAC
addresses for those laptops into the wireless security utility so that only those laptops should be
able to access the wireless network.
Hampton does not keep track of all the laptops, but he is pretty certain that the agency only

purchases Dell laptops. Hampton is curious about this because he notices Bill working on a
Toshiba laptop one day and saw that he was on the Internet. Instead of jumping to conclusions,
Hampton decides to talk to Bill’s boss and see if they had purchased a Toshiba laptop instead of
the usual Dell. Bill’s boss said no, so now Hampton is very curious to see how Bill is accessing the
Internet. Hampton does site surveys every couple of days, and has yet to see any outside wireless
network signals inside the company’s building.
How was Bill able to get Internet access without using an agency laptop?

Which of the following algorithms can be used to guarantee the integrity of messages being sent,
in transit, or stored? (Choose the best answer)

LAN Manager Passwords are concatenated to 14 bytes, and split in half. The two halves are
hashed individually. If the password is 7 characters or less, than the second half of the hash is
always:

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?

Harold works for Jacobson Unlimited in the IT department as the security manager. Harold has
created a security policy requiring all employees to use complex 14 character passwords.
Unfortunately, the members of management do not want to have to use such long complicated
passwords so they tell Harold’s boss this new password policy should not apply to them. To
comply with the management’s wishes, the IT department creates another Windows domain and
moves all the management users to that domain. This new domain has a password policy only

requiring 8 characters.
Harold is concerned about having to accommodate the managers, but cannot do anything about it.
Harold is also concerned about using LanManager security on his network instead of NTLM or
NTLMv2, but the many legacy applications on the network prevent using the more secure NTLM
and NTLMv2. Harold pulls the SAM files from the DC’s on the original domain and the new domain
using Pwdump6.
Harold uses the password cracking software John the Ripper to crack users’ passwords to make
sure they are strong enough. Harold expects that the users’ passwords in the original domain will
take much longer to crack than the management’s passwords in the new domain. After running the
software, Harold discovers that the 14 character passwords only took a short time longer to crack
than the 8 character passwords.
Why did the 14 character passwords not take much longer to crack than the 8 character
passwords?

Jess the hacker runs L0phtCrack’s built-in sniffer utility that grabs SMB password hashes and
stores them for offline cracking. Once cracked, these passwords can provide easy access to
whatever network resources the user account has access to. But Jess is not picking up hashes
from the network. Why?

When writing shellcodes, you must avoid ____________ because these will end the string.

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?

You establish a new Web browser connection to Google. Since a 3-way handshake is required for
any TCP connection, the following actions will take place.

-DNS query is sent to the DNS server to resolve www.google.com
-DNS server replies with the IP address for Google?
-SYN packet is sent to Google.
-Google sends back a SYN/ACK packet
-Your computer completes the handshake by sending an ACK
-The connection is established and the transfer of data commences

Which of the following packets represent completion of the 3-way handshake?
