ARP poisoning, also known as ARP spoofing, is a cyberattack where an attacker tricks devices on a network into associating their network traffic with the attacker's device. This is done by sending fake Address Resolution Protocol (ARP) messages, causing the devices to send their data to the attacker instead of the intended recipient. This enables the attacker to intercept, modify, or eavesdrop on the network traffic, potentially leading to data theft or manipulation. It's like tricking the post office into delivering your neighbor's mail to your doorstep.
Use a network scanning tool or command to identify all IP addresses connected to your network.
Example Command: nmap -sP 192.168.1.0/24 (Replace 192.168.1.0/24 with your network range.)
Choose the IP addresses of the target (the machine you want to intercept traffic from) and the gateway or receiver (the machine whose traffic you want to redirect).
Allow your system to forward packets between different network interfaces.
Command: echo 1 > /proc/sys/net/ipv4/ip_forward
Use the arpspoof tool to send fake ARP messages to the network, redirecting traffic between the target IP and the receiver IP.
Command: arpspoof -i <interface> -t <target_ip> -r <receiver_ip>
<interface>: The network interface you're using (e.g., eth0, wlan0).
<target_ip>: The IP address of the target machine.
<receiver_ip>: The IP address of the receiver (usually the gateway).
Ensure that Wireshark is running in the background to capture and analyze the network traffic for further examination.
Command to Start Wireshark: wireshark
