 ## Previous work
 There have been attempts before to solve this issue. [xray.io](http://www.xray.io/)  Xray works by actually attempting the exploit which doesn't satisfy our system stability constraint. There also exist other applications which attempt to determine a devices attack surface by simply using a lookup based on Android verison/build information.  This causes both false negatives and false positives.  Imagine the case where an OEM has back ported a fix to a device, but the check solely relies on an Android device; false positive.  The case where an OEM upgrades to an Android version/kernel version which includes patches, but manages to break them causes the case of a false negative.
