come on...really ?
but if they're close enough to record the sound you make typing, it's more than likely they can just video you close up in HD, catch even the mouse movements and the files you open, as well as cutting out all the guessing, however intelligent. So it aint a serious security threat. What it may be, is a very useful forensic technique where little other evidence exists...
heaven help us all
And now I present to you: http://xkcd.com/525/
Unsurprisingly, I've heard of this before, probably because the article is from '05. If you are so security-paranoid that you think this might actually happen, just unplug your mic when you're about to type something sensitive...or, better yet, use one of those virtual keyboard things that come with some security suites and use your mouse to type.
You still need a microphone to record the audio, and that point you might as well do something more conventional.
Okay, yeah, maybe. But with various types of keyboards, background noise, difficulty hiding a high quality microphone, it's a bit of an overstatement to say this is a security threat. It would require a targeted attack against a single computer, with physical access.
old and my keyboard has the same notes for majority of the standard keys. which makes this hard for me to believe, at least on todays quieter keyboards
isn't the problem with this that no two keyboards are going to make identical sounds? They may spend years figuring out the sounds on their test boards but in practice, their "V" letter may make a sound identical to my "Shift"...
wow, fuck life then. pshh as if this would ever happen
record 3 random gibberish typing of the keyboards of over 100 minutes and play them at 3 different sources in the same room.... then use a virtual keyboard with a mouse. ;)
wow! you got nice site. Thanks for it.
Very very interesting
Wow, I honestly did not realize this was possible - I heard of various spying methods, but never this...
old, but amazing.
