  D. Load balance each server in a multiple-server architecture

• Question 422:

  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."

  A. If (I > 200) then exit (1)

  B. If (I < 200) then exit (1)

  C. If (I <= 200) then exit (1)

  Correct Answer: D

• Question 423:

  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?

  A. Virus hoax

  B. Spooky Virus

  C. Stealth Virus

  D. Polymorphic Virus

  Correct Answer: A

• Question 424:

  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?

  A. Full Blown Attack

  B. Thorough Attack

  C. Hybrid Attack

  D. BruteDict Attack

  Correct Answer: C

• Question 425:

  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?

  A. Physical access - the attacker can simply copy a Trojan horse to a victim's hard disk infecting the machine via Firefox add-on extensions

  B. Custom packaging - the attacker can create a custom Trojan horse that mimics the appearance of a program that is unique to that particular computer

  C. Custom packaging - the attacker can create a custom Trojan horse that mimics the appearance of a program that is unique to that particular computer

  D. Custom packaging - the attacker can create a custom Trojan horse that mimics the appearance of a program that is unique to that particular computer

  E. Downloading software from a website? An attacker can offer free software, such as shareware programs and pirated mp3 files

  Correct Answer: E

• Question 426:

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

  

  A. Cain and Able

  B. Beat Infector

  C. Poison Ivy

  D. Webarp Infector

  Correct Answer: A

• Question 427:

  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?

  A. Many systems come with default user accounts with well-known passwords that administrators forget to change

  B. Often, the default location of installation files can be exploited which allows a hacker to retrieve a file from the system

  C. Many software packages come with "samples" that can be exploited, such as the sample programs on IIS web services

  D. Enabling firewall and anti-virus software on the local system

  Correct Answer: D

• Question 428:

  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?

  A. Ursula would be considered a gray hat since she is performing an act against illegal activities.

  B. She would be considered a suicide hacker.

  C. She would be called a cracker.

  D. Ursula would be considered a black hat.

  Correct Answer: B

• Question 429:

  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?

  A. Issue special cards to access secure doors at the company and provide a one-time only brief description of use of the special card

  B. Educate and enforce physical security policies of the company to all the employees on a regular basis

  C. Setup a mock video camera next to the special card reader adjacent to the secure door

  D. Post a sign that states, "no tailgating" next to the special card reader adjacent to the secure door

  Correct Answer: B

• Question 430:

  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?

  A. 40-bit encryption

  B. 128-bit encryption

  C. 256-bit encryption

  D. 64-bit encryption

  Correct Answer: B
