If you work a desk job, chances are you keep your smartphone handy on
your desk while you're working. And why not? If you get a call, it's
hard to pull your phone out of your pocket with your butt custom molded
and sweat glued to your chair. The whole point of a mobile phone is
convenience, so there's really no reason not to keep it right there by
the keyboard.
That is, there wasn't until a cadre of supervillains (ahem, "researchers") from Georgia Tech decided to create a program that turns your innocent-looking smartphone into a nosy little asshole that sits there spying on your every keystroke. Passwords, email messages, IMVU sex chats -- your phone could be eavesdropping on all of it. You might suspect that some kind of camera or microphone hack is at play here, but the real modus operandi is even sneakier: As you clack away on the keyboard, your phone's accelerometer can pick up the tiny impacts resounding through your desk and, based on the distance of the keys from the phone, mathemagically deduce which keys you're stroking.

"P-O-R-N-H-U-B ..."
Phones with motion sensitivity on the level of an iPhone 4 can guess
what you're typing with up to 80 percent accuracy. And this clever bit
of spyware can easily Trojan horse its way onto your phone as part of an
otherwise trustworthy-looking app, since it doesn't arouse your
tinfoil-hat suspicions by asking for permission to use your camera or
microphone. The humble tilt sensor is rarely protected against privacy
intrusions, because who would ever have guessed that the little gizmo
that flips your screen over when you turn your phone sideways could also
be used as a goddamn drunken Facebook status update interceptor?
Of course, the algorithm for figuring out what you're typing based on tiny desk tremors is mind-bogglingly complicated, and the whole system is easily defeated by ... just not setting your phone next to your keyboard, so the chances of such an attack by your local garden-variety hacker are low. But since we already know that the government is trying to listen in on us at all times, we're typing up this article with a phone next to the keyboard just to let them know that we know.

It's called subtlety, guys.
