iPad owners using their tablet in public may want to look closely at the people around them. A new app called shoulderPad lets Mac OS X, jailbroken iPad and jailbroken iPhone owners secretly steal your login and passwords. It uses the camera on these devices to track the keyboard input. Specifically, the app looks for the slight blue glow that occurs right after your touch a key. It records these glows, analyzes the pattern and spits out your passwords. All the thief has to do is sit near you and pretend to be using their phone, tablet or computer. This same technique can be applied to recorded footage so be watch out for those surveillance cameras, too.
