PineProxy is a ruby self contained, low resource consuming HTTP transparent proxy designed for the WiFi Pineapple MKV board.
It's based on the dnsspoof infusion by Whistle Master.

You can easily implement a module to inject data into pages or just inspect the requests/responses creating a ruby file inside the modules folder, the following is a sample module that injects some contents into the title tag of each html page.

class HackTitle < PineProxy::Module
    def initialize
        # do your initialization stuff here
    end

    # self explainatory
    def is_enabled?
        return true
    end

    def on_request request, response
        # is an html page?
        if response.content_type == "text/html"
            PineProxy::Logger.warn "Hacking #{http://#{request.host}#{request.url}} title tag"

            # make sure to use sub! or gsub! to update the instance
            response.body.sub!( "<title>", "<title> !!! HACKED !!! " )
        end
    end
end

In order to install ruby and make it work on your WiFi Pineapple, execute the following commands:

opkg update
opkg install ruby --dest usb
opkg install ruby-gems --dest usb
opkg install ruby-core --dest usb
opkg install ruby-enc --dest usb

# fix the ruby gem import error
ln -s /sd/usr/lib/ruby /usr/lib/ruby

Since the great mitmproxy does not run on the pineapple due to missing python dependencies, I thought about making a simple version of it without weird dependecies.

This software is still under heavy development, use at your own risk.
