AP Cybersecurity - Lab: Packet Capture (Station 3)

AP Cybersecurity - Hands-On Lab - Unit 3
Station 03 - Packet Capture
Objective: incompletePoints 0 / 15
Mission

You pulled a capture off the LAN. The gateway is 10.10.20.1. Someone is impersonating it. Work the capture, then report which MAC address is impersonating the gateway and which host's traffic it is stealing. Filter the capture like a display filter - try arp, an IP, or a MAC - and click any packet to expand it.

Need a nudge?
A normal ARP reply answers a request. Filter to arp and read the sequence: who first answered "10.10.20.1 is-at ..."? Then watch for unsolicited replies giving a different MAC for that same IP - and see whose traffic starts routing to it.
Simulated capture - no live traffic. Prototype of rebuilt Station 03.
