1 D Spoof attack is the term used for when the hacker alters the source address of the packet There are different types of spoofing depending on what source address is being altered IP spoofing, MAC spoofing, and e-mail spoofing A, B, and C are incorrect A buffer overflow attack is when too much information is sent to an application and as a result the hacker can run arbitrary code A dictionary attack is a form of password attack using a word list file, and a social engineering attack is when the hacker calls or e-mails an individual and tries to trick them into compromising security 2 C A hybrid attack, like a dictionary attack, uses a word list file but also tries popular modification on the words such as adding a number to the end of the dictionary word A, B, and D are incorrect A brute-force attack is when all the possible character combinations are calculated to try to figure out a password A dictionary attack uses a word list file but doesn t try variations of the word There is no such thing as a buffer password attack
