We all know the NSA is listening to our conversations whether we’re on the phone or not. Can you imagine if someone could listen in to your conversations without you having to speak at all? Researchers at MIT and Georgia Tech looked into other resources on cell phones that are not normally attributed to information leaks, for example microphones and cameras.
Researchers have looked into using a phone’s accelerometer to detect vibrations from a nearby keyboard. At the moment, I do not believe it’s something to be worried about, since it does require the phone to be near the keyboard to detect the vibrations. Also, singular keypresses did not amount to much, but when keypresses are paired and correlated with a word dictionary, useful information is presented.
I found the article and paper to be a very interesting read. I think it’s a great example of a hacker/security mindset. Who would think to use an accelerometer to detect keypresses from a nearby keyboard?
