An anonymous reader writes with news that security experts from Spider Labs released a kernel level rootkit for Android devices
at DefCon on Friday. "As a proof of concept, it is able to send an attacker a reverse TCP over 3G/WIFI shell upon receiving an incoming call from a 'trigger number.' This ultimately results in full root access
on the Android device." The rootkit was developed over a period of two weeks, and has been handed out to DefCon attendees on DVD.
