Hackers can figure out passwords just from the sound of typing

  ... however there are certain caveats to the method. The attacker would need to know the material type of the table that the victim is typing on, as metal and wood surfaces produce different sound wave patterns. So I will be Kickstartering “secure desktops” with random layers of disparate materials, plywood, p-lam, and so forth, plus “secure laptops”, basically trousers with random patches of corduroy, burlap, spandex and whatever sewn onto the thighs.

    Indeed. If a hacker knows the exact material makeup of the table I'm typing on, I think I night have some physical security issues I should address first.

  Michal Zalewski's book Silence on the Wire (2005) had an entire chapter devoted to this called "I can hear you typing".
