I’ve always wanted to try this on airplane wifi to (1) avoid the ridiculous charges and (2) see what happens when I share a MAC address with someone who already paid and is on the network ... I’m guessing nothing good.
Of course I need to first use wire shark or something to get a MAC address that’s already connected to the network. This is where I’m hazy.
- lmohseni 6y agoMaybe just good ol tcpdump?

- zanecodes 6y agoSince most paid wifi networks let you log in without a network password and then gate internet access by redirecting HTTP/DNS requests to a captive portal, it should be possible to launch an ARP spoofing attack [0] to impersonate the default gateway, causing all clients to route their traffic to your device, whereupon you can examine it with WireShark or tcpdump to get at their MAC addresses. I've tried something similar while bored on a flight, but sadly the Surface Pro 7's Windows network drivers don't seem to let you change your MAC address.

- Nextgrid 6y agoIf it's an open (unencrypted) network you don't even need to ARP spoof. Their MAC address will already be in cleartext in the packets - just start your interface in monitor mode on the proper channel and capture some traffic.
