An ARP + DNS spoofing script for a local switched network that effectively "jams" all requests with a specified image, or randomly chosen image.
Sets up a lightweight HTTP server, and intercepts all HTTP traffic so that a specified image is returned as the response to all HTTP requests. Also works for HTTPS URLs, though a "self-signed certificate" warning will appear for the user.
Uses wlan0 as the default network interface.
This is an old project and may have bugs.
