Companion code to my blog post

How does a TCP Reset Attack work?

The supporting code for my blog post "How does a TCP Reset Attack work?" See that post for much more detail.

To run

Pre-requisites: install ncat. Comes pre-installed on OSX.

1. Install dependencies: virtualenv venv && source venv/bin/activate && pip install -r requirements.txt
2. Setup TCP connection. In one terminal window run nc -nvl 8000 to set up a server
3. In another terminal window run nc 127.0.0.1 8000 to connect to the server
4. In a third window run python3 main.py to run our sniffing program
5. Type into one of the TCP connection windows. You should see the sniffing program log some output, send a RST packet, and the nc connection should be broken
