TLDR: they hacked a less secure network in range of their target network, then SSHed into a laptop on the less secure network and used it to hack the target network. Possibly even daisy chained less secure networks. The point of this was to not sit in a suspicious car next to your target while you brute force their wifi password (they have been caught previously).

My question is: how do you get caught while hacking wpa2? I’m not an expert, but I assume you can get the data you need to do an offline bruteforce just by driving by and sitting at a red light a few times, which is not suspicious at all even if you have a laptop out. Or did they try to hack wpa3? If so, I assume it’s trivial to detect online bruteforce attempts and stop responding to them, or even just whitelist MAC addresses?
