This is another post in the ‘fun with arp’ series I’ve started. I will show you how you can eavesdrop on the MSN Conversations of your friends and enemies. This is an ARP hack, so it only works on a LAN. I described in the “Howto hack the computers in your LAN” post how you can use arp packages poisoning/spoofing to route all traffic on a switched network through you computer. We are going to use the same technique here, with some adjustments.

This is what we want to do:

• Eavesdrop on a users Msn Conversations

This is how we’re going to do it:

1. Poison the arptables of the target and the standard gateway to make all traffic go through us
2. Filter out the packages that contain the MSN messages

I am going to show you a way to have fun with the users of your lan. The idea i got from Upside-Down-Ternet article written by -someone-. He/she described how to play a trick on the neighbours that was leeching off his wireless, by turning all the images on the websites they were surfing on upside-down. It’s a fairly simple deal when you are in control of the network’s gateway, but if you are just connected to the lan like everyone else, you need a bit of low-tech hacking.

This is what we want to do:

• Make the target send all http packet to us instead of the gateway
• Forward them to the real gateway
• Modify the replay, with the pictures upside-down
• Forward the replay to the target

This is how we’re going to do it:

1. Poison the ARP table of the target
2. Set up our pc as a gateway router
3. Send all http requests through a squid proxy
4. Turn images upside-down with a squid script
