Playing more with the Android Scripting Environment, I wrote a simple script to display any access points in wifi range. Once you select an SSID, it will display some basic info on that AP, such as the MAC address and encryption type. If you have a rooted phone, you could theoretically brute force an APs password using *nix iwconfig commands. The next post I will show some quick and dirty code to brute force passwords. But for now here is the script for some UI WiFi scanning.
It works on my machine.
