Steven the hacker realizes the network administrator of Acme Corporation is using syskey in
Windows 2008 Server to protect his resources in the organization. Syskey independently encrypts
the hashes so that physical access to the server, tapes, or ERDs is only first step to cracking the
passwords. Steven must break through the encryption used by syskey before he can attempt to
use brute force dictionary attacks on the hashes. Steven runs a program called “SysCracker”
targeting the Windows 2008 Server machine in attempting to crack the hash used by Syskey. He
needs to configure the encryption level before he can launch the attack. How many bits does
Syskey use for encryption?

Bob waits near a secured door, holding a box. He waits until an employee walks up to the secured
door and uses the special card in order to access the restricted area of the target company. Just
as the employee opens the door, Bob walks up to the employee (still holding the box) and asks the
employee to hold the door open so that he can enter. What is the best way to undermine the social
engineering activity of tailgating?

Ursula is a college student at a University in Amsterdam. Ursula originally went to college to study
engineering but later changed to marine biology after spending a month at sea with her friends.
These friends frequently go out to sea to follow and harass fishing fleets that illegally fish in foreign
waters. Ursula eventually wants to put companies practicing illegal fishing out of business. Ursula
decides to hack into the parent company’s computers and destroy critical data knowing fully well
that, if caught, she probably would be sent to jail for a very long time. What would Ursula be
considered?

Attacking well-known system defaults is one of the most common hacker attacks. Most software is
shipped with a default configuration that makes it easy to install and setup the application. You
should change the default settings to secure the system.
Which of the following is NOT an example of default installation?

BankerFox is a Trojan that is designed to steal users’ banking data related to certain banking
entities.
When they access any website of the affected banks through the vulnerable Firefox 3.5 browser,
the Trojan is activated and logs the information entered by the user. All the information entered in
that website will be logged by the Trojan and transmitted to the attacker’s machine using covert
channel.
BankerFox does not spread automatically using its own means. It needs an attacking user’s
intervention in order to reach the affected computer.

What is the most efficient way an attacker located in remote location to infect this banking Trojan
on a victim’s machine?

This tool is widely used for ARP Poisoning attack. Name the tool.

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 – though slow. Usually, it tries every possible letter and number combination in its
automated exploration. If you would use both brute force and dictionary combined together to have
variations of words, what would you call such an attack?

You receive an e-mail with the following text message.
“Microsoft and HP today warned all customers that a new, highly dangerous virus has been
discovered which will erase all your files at midnight. If there’s a file called hidserv.exe on your
computer, you have been infected and your computer is now running a hidden server that allows
hackers to access your computer. Delete the file immediately. Please also pass this message to
all your friends and colleagues as soon as possible.”
You launch your antivirus software and scan the suspicious looking file hidserv.exe located in
c:\windows directory and the AV comes out clean meaning the file is not infected. You view the file
signature and confirm that it is a legitimate Windows system file “Human Interface Device
Service”.
What category of virus is this?

One of the effective DoS/DDoS countermeasures is ‘Throttling’. Which statement correctly defines
this term?

Choose one of the following pseudo codes to describe this statement:
“If we have written 200 characters to the buffer variable, the stack should stop because it cannot
hold any more data.”
