McJumpBox Leveraging free corporate Wifi for fun/profit

RF Village @ DEF CON 33 · Day 1 · RF Village
In this engaging talk, "McJumpBox Leveraging free corporate Wifi for fun/profit," also known as "Wi-Fi Wormhole" to avoid potential trademark disputes, speaker Loaning delves into the fascinating and somewhat rebellious pursuit of creating untraceable, long-range internet connectivity. The core concept revolves around deploying a low-power device onto the roof of a building offering free public Wi-Fi – such as a McDonald's or Starbucks – and then connecting to that device from several miles away using a companion unit. This setup effectively creates a "wormhole" that provides internet access while geographically obfuscating the user's true location, making their online activities unattributable.
AI review
A genuinely fun, technically honest RF Village talk that does exactly what it promises: builds a real thing, shows you the ugly path to get there, and lands a working sub-GHz wormhole with range data to back it up. Not groundbreaking research, but the hardware journey, the $40 DIY alternative, and the defender blind-spot call-out on 802.11ah monitor mode give it real substance.
