Keyboard Sound Aids Password Cracking
stinerman writes "Three students at UC-Berkley used a 10 minute recording of a keyboard to recover 96% of the characters typed during the session. The article details that their methods did not require a 'training text' in order to calibrate the conversion algorithm as has been used previously. The research paper [PDF] notes that '90% of 5-character random passwords using only letters can be generated in fewer than 20 attempts by an adversary; 80% of 10-character passwords can be generated in fewer than 75 attempts.'"

Looks like you're screwed because my luggage password is 5 digits long, but all digits are numbers in a sequential order starting with one. Ha ha!

Another old fashioned way to get passwords w audio: Just tap the "help desk" phone line.
... that my voice is my passport.
Go figure, typing properly now means you get your password cracked.
Guess that's all the more reason to keep that Cheetos bag crinkling as you type. Gotta stop the commies!
Security experts recommend you don't speak the name of the key you're hunting for as you type your password with a single finger.

Just make a clicking noise with your tongue and the roof of your mouth as you type. It sounds almost identical, and you'll automatically sync the sound up with each keystroke.
Try it.

Good idea. They sell those at the same movie prop houses that carry 57-shot revolvers, self-igniting gasoline, and phones with "AT&T" written on every surface.

With these clicky buckling springs, they'll be able to sniff my password from miles away!
Be careful, chief. Lets type in the cone of silence.

This reminds me of a sysop I once worked with. Every time he logged in you could clearly identify the rhythm of M-I-C-K-E-Y M-O-U-S-E. Sometimes he was even stupid enough to hum the tune as he typed it. And this idiot was one of the senior IT guys at a major oil company.
That's it. From now on, whenever I'm typing a password I'm going to scream at the top of my lungs. How about that stopid password stealers!?
It's also incredibly helpful when they mumble their password as they type it.
Spyware attempting to hash out your keystrokes by listening to the keypresses instead of grabbing the strokes directly is a bit like a person trying to enjoy music by watching the equalizer lights flicker instead of using the speakers.

I'm amazed. No, stunned. No.. umm, what's the opposite of "amazed" again?
Hey, I've done that! It's a great exercize for increasing the pattern-matching ablities of your brain! You have no idea how good it feels when you finally 'hear' the music just by watching the lights...
(Well, at least I think so.)

it is 'password' It works about 25% of the time.

Learn logic.
Maybe while we're waiting around for the target to log into his computer, touch none of the other keys, and immediately leave, we can get to work on a teleporter to remotely swap out his keyboard before he comes back. Oh, and bonus! We can beam his original keyboard right into the fingerprint oil age analysis machine (with millisecond accuracy so that we can truly "backtrack" his password) that we'll also invent.

I write /whois and /away much more often than my passwords.

Here we see Agent Small and Agent Geoffries working on a real, live Password Hacking "Evesdrop Machine". If they can just hear enough of the nefarious criminal's activities, the can garner all of his secrets.
AS: Okay, we're getting something.
EM: *click click clickity click*
AG: What was that?
AS: It sounded like a URL. He must be going to a website. The machine will try to crack the URL.
EM: *click*
AG: That was a mouse click, wasn't it?
AS: Yup, not very helpful.
EM: *thump thump thump thump*
AG: What's that?
AS: It sounds like a hard and regular pounding of something. I can't quite make it out.
AG: Hey, the machine's got the url. www.ultimatepron....

How about a zoom lens?
The parent poster is right. Photographic techniques are probably easier across the board. But there is no reason you can't use both.
I'm ok though. I type in my password with mittens in a dark room. I wish they would let me out of here.
Oh, crap.
How can we continue to believe in a just universe and freedom to eat crackers if we have no ale?

I'm not a nerd. Nerds are smart.
Got a bright idea? Maybe we should just glue the user to the computer.
Thank god I've spent the last five years practicing how to make keyboard clicking sounds with my mouth. You'll never get my password!
