@Kasperwoest The trick for probing a WPA3 is by using 9 tries to narrow it down as much as you can then try cracking every single number, since there's no limit to cracking tries.
(try to narrow it to about 10-30 possibilites)
to get the mac you do the following commans:
getip (SSID)
inject (ip)
listdevices (ip)
then you do "mine (ip) (MAC)
The mac is that long line of letters and numbers separated by a colon.
Looks like this: AA:BB:CC:DD:EE:FF:GG
