All Your Keystrokes Are Belong To Us
Listen to this article
I stumbled upon this paper while doing my weekly browse through articles on CleverCS. To quote from the abstract:
... a novel attack taking as input a 10-minute sound recording of a user typing English text using a keyboard, and then recovering up to 96% of typed characters...
They even run the recovered text through a spell-checker which successfully corrected a mistake in the text as it was originally typed lol.
Pretty cool idea although I figure if you can sneak a microphone into a building—say by sending someone a bunch of flowers or a promotional desk-lamp, etc.—you can probably just as easily "upgrade" someone's "faulty" keyboard and record keystrokes that way instead.

There was a technology from 1970s used by intelligence agencies which captured (from withing a certain radius) and filtered tiny electromagnetic signals produced when typing the keys (or produced when it apppeared in screen - i dont remember) and re created the typed text
