Which of the following would NOT be a logical choice to include in a Forward DNS Brute Force attack?

Select one of the following:

  • mars

  • mail

  • www

  • proxy

Question 6 of 21

Medal-premium 1

Metasploit is utility built into backtrack and is useful for:

Select one of the following:

  • Determining which ports are open and available for attack

  • Querying DNS to gain more information about a network

  • Capturing authentication traffic off the network and then cracking target passwords

  • Using existing exploits to deliver a specific payload to a target machine

Question 7 of 21

Medal-premium 1

An attacker can get access to a command line on a target machine behind a NAT firewall provided they...

Select one of the following:

  • Have access to port 1047 on the target machine

  • Can establish a reverse bind shell with the target machine

  • Can establish a bind shell with the target machine

  • Since a NAT firewall drops ALL traffic originating outside the network, it is not possible to get command line access to a target machine

Question 8 of 21

Medal-premium 1

The process of sending out a fake MAC address to target machines in a Man in the middle attack is known as:

Select one of the following:

  • MAC Rendering

  • MAC engineering

  • ARP Poisoning

  • ARP engineering

Question 9 of 21

An effective tool an attacker might use to discover information about the topology and layout of your physical network would be;

Select one of the following:

  • Netcat

  • Ettercap

  • Maltego

  • Metasploit

Question 10 of 21

Medal-premium 1

The registry on a Windows 7 machine, is located in the ______________ directory by default.

  • C:\windows\system32\drivers\etc

Question 11 of 21

Medal-premium 1

The use of rainbow tables is effective in greatly reducing the time required for cracking password hashes on a Windows machine. If you were interested in attacking passwords on a Linux machine, rainbow tables would;

Select one of the following:

  • Greatly reduce the time required to crack the passwords since the hashes could be run against the rainbow table

  • This would not help speed up the process since Linux stores passwords as reversibly encrypted passwords which would is a different technology

  • This would not help speed up the process since password hashes on a Linux system are "salted", making rainbow tables useless

  • This would not help speed up the process since password hashes on a Linux system are created using SHA-1 which is unbreakable

Question 12 of 21

Medal-premium 1

One concern with logging on as the local administrator account on a domain machine is that;

Select one of the following:

  • The password of the domain administrator will be cached in the registry

  • The machine will cache credentials of a user who has rights to modify

  • This will overwrite the credentials of other users when running applications

  • There is no concern in this case, since the local administrator has no rights in the domain

Question 13 of 21

Select one of the following:

  • Have access to port 1047 on the target machine

  • Can establish a reverse bind shell with the target machine

  • Can establish a bind shell with the target machine
