Pixie works by exploiting weaknesses in the generation of the E-S1 and E-S2 nonces which are used to produce the enrollee hash, as described in the Pixie Dust Attack. Traditional attacks attack the two halves of the WPS PIN (PSK1, PSK2) in an online attack, essentially brute-forcing all possible options for the PIN until it is found. This has to be done ...

This kind of depends on how strong you want your network security policy to be. Lets point out the main good and bad things about a WiFi network: Good: Convenient for the office workers to work from anywhere in the office No need for cables and switches (This saves money and time) Keep better track of your users and have more control straight from the ...

Who can view what you are doing? You, anyone that uses the same router (assuming you're not in Access Point isolation mode), anyone that has access to the router's access logs, possibly including the person that set up the router, and the Internet Service Provider. WPA prevents other people without access to the router from viewing your data casually from ...

Contrary to a common misconception, the network key is not the encryption key. The WiFi communication is encrypted on its own using a key exchange protocol. This makes it impossible for anyone without abnormally huge processing power to decrypt anything that goes through. That said, if the person controls the router, that changes things as the router ...

The attack vectors remain the same. The only difference is that mobile phones might provide an additional attack surface with other services reachable like Bluetooth and GSM/UMTS/GPRS/... Check public vulnerability databases for entries regarding WLAN or other network issues to determine the known attack surface of mobile devices. Once in a while there is ...
