A. Exploiting DHCP servers to deliver the IP address of poisoned DNS servers. & E. Changing the host's file of a user's computer. Explanation: Pharming redirects one website's traffic to another, bogus website that is designed to look like the real web site. Once there, the attacker tricks the user into supplying personal information, such as bank account and PIN numbers. Pharming works by resolving legitimate URLs to the IP address of malicious web sites. This is typically done using one of the following techniques: ¥ Changing the hosts file of a user's computer ¥ Poisoning a DNS server ¥ Exploiting DHCP servers to deliver the IP address of malicious DNS servers In DHCP leases. Search engine results poisoning is not typically associated with pharming attacks. A man-in-the-middle attack occurs when the attacker intercepts legitimate network traffic and then poses as one of the parties involved in the network communication. A dictionary attack is used to crack passwords by guessing the password from a list of likely words.
