My main focus is in the mainĪrpspoof program the functionality of sweep.sh will probably be incorporated Since a few other people seem to be interested in it I've been cleaning it up aīit recently and adding a few more features. This project was originally written for my networking class last semester, but Things you change yourself are prefixed with $'s this time to distinguish from Iptables -t nat -A PREROUTING -p tcp -dport 80 -i $INTERFACE_NAME -j DNAT (port 443) is significantly harder to mess with, so I don't try. You've set them up not to conflict if you're running both). Our machine, which Apache is listening on as well as Squid (just make sure We set up iptables to redirect anything coming through port 80 to port 3129 on However, since it's your machine, you can have your way with them, so By default Linux just forwardsĪny IP packets destined for elsewhere, so the ARP spoof by itself won't reallyĪffect anything other than making the victim's packets pass through your And one more thing that doesn't really fit neatly anywhereĮlse: the iptables rule to redirect the traffic. There are also some other relevant things, for example the sample website isĪvailable under the http directory, and the Apache and Squid configuration filesĪre here as well. sweep.sh INTERFACE_NAME Ĭage.sh is a simple URL rewriter script for Squid-it just takes any URL and Port 6000 but firewalls almost everything else, including ICMP.

Reason I was unable to determine, Windows responds to random TCP connections on Spoofing, which prints out the IP addresses of everyone who responded in someįashion to the ping from the tcping program (not mine) on port 6000. There is also a flag to do only the ping sweep and not attempt the Obviously you shouldn't do this unless you knowĮxactly who will be affected by it and you're prepared to handle theĬonsequences.

To prevent even this weak defense mechanism from deploying, the program has an option to keep resending the phony packet every X number of seconds. Linux) are very suspicious of spurious ARP responses like this and will quickly figure out the ruse, but Windows will happily chug along in blissful ignorance until you annoy it by taking too long to respond to requests. I then use these addresses to construct a phony ARP response to the victim that tells them that I am their default gateway (or any other IP address if you don't want it to be the default gateway).

The arpspoof.c file sends 2 ARP requests, one to the default gateway and one to the victim, to get their MAC addresses. A program to perform an ARP spoofing attack against someone else on your local unencrypted network.
