This tiny (51KB) app finds the guest network's default password for almost any Linksys E-series router! The guest network is usually a combination of a color and animal name with the string "-guest" appended. An example is: YellowZebra-guest. If you have a linksys router with a guest network, give it a try. Just connect to the guest network, and run the app. It will take a few minutes at the most to find the password. This is my first android app, and I have no prior experience with mobile apps, so give me some feedback. And it's also the first "vulnerability" that I discovered.
