An attacker broadcasts DHCP requests with spoofed MAC addresses with the help of tools such as Yersinia, Hyenae, and Gobbler. Which tool is commonly used to such a DHCP attack?

• A. Yersinia
• B. Hyenae
• C. Gobbler
• D. Mole

Answer: (A)

DHCP starvation/poisoning relies on flooding the DHCP server with requests using spoofed MAC addresses so that the pool of available IPs is exhausted. Yersinia is a specialized network attack tool that can craft and send DHCP messages (like DHCPDISCOVER and related frames) with arbitrary, spoofed MACs, enabling rapid, automated exhaustion of the DHCP pool. This direct capability to generate DHCP traffic at the protocol level with spoofed identities is what makes Yersinia the commonly used choice for this kind of attack. Hyenae and Gobbler exist in the ecosystem as networking tools, but they are not as directly tied to performing a focused DHCP starvation attack as Yersinia is. They may handle different tasks or offer alternative testing features, so they’re not the standard pick for this specific scenario.
