This reminded me of an old app that would scan the MAC addresses of devices already connected to a paid WiFi network. You would then just change your MAC to one that already paid for the WiFi, and then reset it once you were done.

Wouldn't that lead to interference with the original device using that MAC address? Ie both of you getting packets meant for the other etc?

		Yes. It’s a bad (maybe even illegal?) thing to do. The victim device will start losing packets, and it’ll look to them like the network is just unreliable. Eventually they give up and disconnect, and you take full control.

		Yeah. I think any network with STP/anti-flapping enabled will shut that down pretty quickly though.
