The Preferred Network List, or PNL, is a list of Wi-Fi network names your device automatically trusts. 1) Purge networks you donвЂ™t need from your preferred network list By taking the following steps, you can reduce your attack surface and keep yourself safer when using Wi-Fi at home or on the go. To reduce these risks, we can lock down behaviors that leak private information and or make our devices more vulnerable. For anyone not wanting their device to broadcast where they work or have been recently, this can be both a privacy and security issue. Mobile Wi-Fi devices can easily be tracked between locations, leaking network names that can reveal information about the owner. Wi-Fi is an attack surface that can also follow you around. This gives hackers the flexibility to pick the weakest link, relying on a target to make critical mistakes and targeting any vulnerability thatвЂ™s easy to exploit. Hackers targeting Wi-Fi can decide whether to attack the network itself or to go after any connected devices. While this does happen, Wi-Fi can also be abused to track users by their devices, compromise passwords with phishing attacks, and reveal information about where a person works or travels. When the average person thinks about Wi-Fi hacking, they probably imagine a hacker breaking into their local Wi-Fi network. вЂњThis really opened my eyes to AD security in a way defensive work never did.вЂќ
