Hi guys, I live in the area where there are mostly elder people and I'm not really worrying about someone hacking into my system. Therefore, my current security consists of simply hidden SSID and wireless MAC filtering. Nevertheless I'm wondering how would someone be able to find some of allowed MACs in my wifi filter list. I know it's easy to replace MAC on a client card, but you need first to know some of allowed MACs, right? How can an attacker find those MACs?
