Stagefright is a good example of Android OS.
This attack is from April 2015.
Now, the Stagefright vulnerability
exists on the device, and it executes code execution.
So what this means is, you have exploit libraries
that exist on the phone, and you will get Trojanized audio
and video files.
You don't even have to watch these audio and video files.
Once they land on the handset, it is now
impacted with this Malware.
Any time you see code execution, what
this is where the device can go out and act
on the user's behalf.
You want to make sure that you are
examining devices that could be impacted by Stagefright.
