Version: 0.1.0

This is a Rust implementation of an ARP and DNS spoof attack.

Rozmitmat is a vision of a hacking tool I am developing for a knowledge gathering about how network and Linux/Windows systems work. The project consists of two programs: rozmitmat which does an actual work and rozmitmatgui which is a simple GUI app. For packets manipulation the program uses an external function written in Python with a powerfull package called Scapy. Rozmitmat executes this function which is much simpler than trying doing the same in Rust.

Those apps work on Linux only.

sudo apt-get install libpcap-dev build-essential python3-dev libnetfilter-queue-dev scapy
pip3 install scapy

To execute ARP-DNS MITM attack run rozmitmat as:

sudo ./rozmitmat --interface eth0 --target 192.168.0.22 --gateway 192.168.0.1 --domain example.com --redirectto 192.168.0.1

interface is the name of the network interface you want to use as the input device

target is the target IP of the computer you want to hack

gateway is the router IP

domain is the domain you'd like to spoof, e.g.: bing.com

redirectto is the IP address where the domain address will be redirected to

Add --proxy (-p) to forward HTTP/S communication to a proxy like mitmproxy. Enter a port number which the proxy is listening on.

Add --verbose (-v) for more detailed output. Works the best in conjuction with the -l option.

Add --log (-l) for saving pcap file with the traffic; with -v option shows data like: DNS requests, source and destination addresses, HTTP body.

You can write of course also like this:

sudo ./rozmitmat -i eth0 -t 192.168.0.22 -g 192.168.0.1 -d example.com -r 192.168.0.1

If you only want to spoof ARP:

sudo ./rozmitmat -i eth0 -t 192.168.0.22 -g 192.168.0.1 -v 1 -l 1

Create forwarding to a proxy:

sudo ./rozmitmat -i eth0 -t 192.168.0.22 -g 192.168.0.1 -v 1 -l 1 -p 8080

In two cases above a DNS spoof attack will not be executed. Now you're a man in the middle and you can use other tools for more advanced actions.

CTRL-C will stop execution. The program will try to reverse changes: clean iptables and set original ARP data. If you had a previously set iptables all will be wiped out, nat also.

pcap file will be created in the working directory if --log parameter has been specified. It can be read by Wireshark for a future analysis.

Right click on the Output windows to see a sub-menu.

It uses egui (https://github.com/emilk/egui)

You have to copy rozmitmat to a rozmitmatgui's folder. Remember to run rozmitmatgui as root with sudo command or su.

I found that DNS spoofing implemented here not working well. Seems like only DNS requests based on UDP protocol could be spoofed. I invite you to take a part in this project if you'd like to help.
