teeworlds 0.7 MITM proxy

Man in the middle teeworlds proxy. Repacking chat messages. For now only the teeworlds 0.7 protocol is supported.

run the proxy

go build
./proxy -H 127.0.0.1 -P 8303 -p 8333

Start a teeworlds 0.7 server on port 8303 on your machine. Connect to 8333 with your 0.7 client and you will be proxied to the 8303 server.

what it does

It uses a teeworlds protocol implementation written in pure go to unpack, change and then repack the traffic. The current example changes all chat messages to "capitalism.". So a client connecting to the proxy will only see "capitalism." in the chat.

Using this command you can spin up a proxy server on localhost:8303 which connects to a ddnet CHINA server.

./proxy -H 101.43.114.27 -P 8327-p 8303

Once connected with a 0.7 client the chat will be full of capitalism messages.
