By now it's pretty well established that cell phones, especially smartphones, are insecure.
No one is surprised that apps phone home with private data, run ads that do the same, or that the amount of malware available for Android and iOS is growing faster than almost any other type of software.
Smartphone malware is so common virus authors debate how best to monetize their opportunities as blithely as dot-commers did a decade ago, while more sophisticated authors build smartphone botnets with as many as a million members or remote-access malware that can open a door for hackers wanting to get at a user's other systems.
Still, most people think of the smartphone security threat as an outbound phenomenon – anything you put on a smartphone could find its way into the wrong hands through any of the methods above or more directly when the phones are lost or stolen.
