ARP Spoofing Guide

What is ARP Spoofing?

ARP Spoofing is a type of attack where an attacker sends falsified ARP (Address Resolution Protocol) messages over a local network. This allows the attacker to intercept, modify, or stop data in transit, often leading to Man-in-the-Middle (MitM) attacks.

How ARP Spoofing Works

• ARP Protocol: ARP maps IP addresses to MAC addresses on a local network.
• Spoofing: The attacker sends falsified ARP messages to associate their MAC address with the IP address of another device.
• Interception: Traffic intended for the victim is redirected to the attacker.
• Modification: The attacker can modify or stop the traffic before forwarding it to the victim.

Tools for ARP Spoofing

Step-by-Step Guide to ARP Spoofing

Here’s how you can perform ARP Spoofing (for educational purposes only):

1. Choose a Tool: Select a tool like Ettercap or Bettercap.
2. Set Up the Attack: Position yourself on the same network as the victim.
3. Spoof ARP Messages: Use the tool to send falsified ARP messages.
4. Intercept Traffic: Capture and analyze the redirected traffic.
5. Modify or Stop Traffic: Modify or stop the traffic before forwarding it to the victim.

How to Protect Yourself

To protect yourself from ARP Spoofing, follow these steps:

• Use Static ARP Entries: Configure static ARP entries to prevent spoofing.
• Enable Port Security: Use port security on network switches to prevent unauthorized devices.
• Monitor Networks: Continuously monitor for unusual ARP activity.
• Use VPNs: Use a VPN to encrypt your internet traffic.
