Ethical Hacking Essentials Practice Test

Which attack involves forging a large number of ARP packets?

1. DNS poisoning

2. MAC duplicating

3. ARP spoofing

4. DHCP starvation

The correct answer is: ARP spoofing

The attack that specifically involves forging a large number of ARP packets is ARP spoofing. This technique is used to link the attacker’s MAC address with the IP address of a legitimate device on the network. By sending false ARP messages, the attacker can make other devices on the network believe that they are communicating with the legitimate device when, in fact, they are communicating with the attacker. ARP spoofing can lead to various malicious activities, such as man-in-the-middle attacks, where the attacker intercepts and potentially alters the communication between two parties. The technique relies on sending a flood of ARP requests and responses, which is why it involves forging a large number of ARP packets. Other options involve different types of attacks. For instance, DNS poisoning targets the Domain Name System to redirect users to fraudulent sites, whereas DHCP starvation aims to exhaust the available IP addresses in a DHCP server so that legitimate devices cannot obtain an IP address. MAC duplicating refers to altering the MAC address of a device, which is a separate action and does not involve ARP packets specifically.
