My eventual purpose is to get to a level where I could execute the following script: from scapy. But now I want to step it up and redirect every message he sends and receives through me. from scapy.all import from scapyhttp. Now, this perfectly works for a passive MITM - I can see everything that the client sends and receives. #eth0 is the interface that is connected to the internet #wlan0 is the interface on which the hotspot is. Iptables -table nat -append POSTROUTING -out-interface eth0 -j MASQUERADE
Iptables -append FORWARD -in-interface wlan0 -j ACCEPT Man-in-the-Middle with RotMiTM() This is a demo of how to intercept and proxy.
So, I will be explaining it line by line. I already have the following simple script: hotspotd start #a script that runs dnsmasq as both a DNS and DHCP server, configures and starts a hotspot WRITING THE PROGRAM Step 1 : Intercepting the packets I have used a function which converts a normal packet into a scapy packet. I think that the correct direction of going about accomplishing this is with iptables but not sure exactly what arguments would fit to make this work. It comes with many of the common network layers built in. How can I alter packets that my client sends and receives without interrupting my own communication with other services? There must be a way to route all of the packets the client both sends and is about to receive (before forwarding them to him) through my script. Scapy is a python package used to sniff, analyze, and send and receive arbitrary network packets. configure & make and the install the model using python setup.py install, setup.py can be found at the python directory in libdnet. Assuming I managed to be in the middle of the communication between a client and a server (let's say that I open up a hotspot and cause the client to connect to the server only through my machine). If you are using git source then compile and run with.
