What problem does it solve?

ARP poisoning is a network-layer attack where attackers associate their MAC with legitimate IPs to enable MitM. This Skill provides a multi-layered approach to detect and respond to ARP spoofing using ARPWatch, Dynamic ARP Inspection, Wireshark filters, and a Python detector.

Core Features & Use Cases

• Deploy ARPWatch for continuous monitoring across the network.
• Validate ARP integrity with Dynamic ARP Inspection and DHCP snooping prerequisites.
• Use Wireshark detection filters to surface suspicious ARP activity.
• Run a Python ARP monitor to detect MAC/IP changes, gratuitous ARP, and spoofing patterns in real time.
• Apply in SOC investigations, enterprise networks, or lab environments to identify MitM attempts and protect gateway traffic.

Quick Start

Start real-time ARP poisoning detection on your network interface using the ARPWatch/DAI/Wireshark workflow and optional Python monitor.
