Traffic on a local network can be spied on both by other users and by an attacker who records the traffic and decrypts it after learning the password later. With the current WPA2 standard, this is not the case. This means that in the new WPA3 standard, recorded Wi-Fi traffic can’t be spied on even if the attacker gains knowledge of the Wi-Fi password later. One of the fundamental flaws of WPA2 that’s being fixed in WPA3 is the concept of forward secrecy. By finding which network names show up in the PNL of multiple nearby devices, a hacker can hijack the data connection of many devices at the same time with a single rogue network with a name like “attwifi.” If you have networks similar to those on the list above saved in your device’s PNL, you should delete them immediately! 2) Use a VPN to keep your local traffic encrypted Many nearby smartphones attempted to join networks with names they had connected to before, revealing which they trust. In the attack above, I used a $3 esp8266 microcontroller to create up to a thousand fake networks. The risk of your device connecting automatically to a rogue AP pretending to be open Wi-Fi is much higher than encountering a malicious network with the exact same name and password as one stored in your PNL. At a minimum, you should remove all open Wi-Fi networks from this list. In Windows, you can delete your preferred networks by going to “Manage known networks” and clicking “Forget” on any networks you don’t want your computer connecting to automatically. Without other precautions, this could allow a hacker to load phishing pages, track which sites you visit, and learn which apps you’re using.
If you leave your smartphone Wi-Fi on in public, your device won’t warn you when automatically joining an open network with a name matching any that you’ve joined before. That means that after connecting to a Starbucks Wi-Fi network a single time, your device will remember and connect automatically to any open network with the same name.įor a hacker, creating rogue access points which mimick the names of common open Wi-Fi access points is the easiest way to track nearby devices and conduct MITM attacks. This list is created from the networks you connect to over time, but it can’t distinguish between networks which share both the same name and type of security. The Preferred Network List, or PNL, is a list of Wi-Fi network names your device automatically trusts. 1) Purge networks you don’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 that’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.
