Microsoft Wireless Keyboards Crypto Cracked
They might have picked a poor IV (http://www.schneier.com/blog/archives/2005/01/microsoft_rc4_f.html) or implemented a bad random number generator (http://www.net-security.org/news.php?id=15463) or made any number of other mistakes (again) that render the actual encryption meaningless. The attack opens the way up to all sorts of mischief including keystroke logging to capture login credentials to online banking sites or email accounts. Death...

Roger • February 19, 2008 3:22 AM @Chris: A good overview of Bluetooth security can be found at: http://gsyc.es/~anto/ubicuos2/bluetooth_security_and_hacks.pdf Generally speaking, attacks on the encryption algorithm are the least of your http://www.theregister.co.uk/2007/12/03/wireless_keyboard_crypto_cracked/
You really don't have to though; there are only 256 possible encryption keys. As for security, I dont really care if someone is sniffing this comment. These can be brute-forced if the attacker eavesdrops on the initial pairing process, or can induce the user to re-initialise the connection.
It is actually harder to pick up the signal than it is to break the cipher... Why bother breaking encryption at all?

Breaking the simple encryption on the device was easy, Moser says. "The valid encryption key is transparent during the pairing process, which gives us the possibility to listen to the keyboard When the second one was turned on, it found the devices on the other desk instead of its own ones, and then anything the first user did was echoed on the

Due to its nature, it can be tapped with little effort," said Dreamlab's Max Moser. check my blog you could watch their hands, plant a web cam, shoulder surf, TEMPEST technology from the 80's, a well placed mirror may even do the trick, etc)Security people are well of this Why not just let him continue in his ignorance..

Do not use a bluetooth keyboard if you are worried about security - it transmits too far (10M plus at least 20M leakage with a good receiving antenna) and the encryption BAH...

I cracked a wireless keyboard just the other day. todbot has updated the log for blink(1) sconces. or to play "You have been pwned" on blaring speakers after the cracking is over ? Keyboards that communicate via Bluetooth are much more secure, Moser said, because the key must be sniffed at the moment when it's exchanged -- in Bluetooth's case, that's when the keyboard
According to heise Security: Max Moser and Philipp Schrodel say that decryption was very easy because the devices use a simple XOR mechanism for encryption and the keys are only one Nobody gives a damn about your sisters wedding or new second cousin's baby's name. Almost a joke. have a peek at these guys This wouldn't be that big a deal, except for the fact that they were about 30 feet away from each other.
Dude's being an asshat. Everyone has a bluetooth chip these days, so a free download of capture software and a quick decrypt… Hence the issues with wireless headset sniffing. That's the magic of a parabola. So they could have done better key exchanges stuff etc.
Others suggested dish antennas.

Honestly if you are close enough to employ this technique (including operating the kind of hardware necessary to do this undeniably cool hack) then you are close enough to shoulder surf I must be thinking of a different Microsoft.... Added to that is that wireless mice are lower resolution/speed/quality than most similarly priced wired counterparts, and not only is there lag, but there are many more jumps, jiggles, and miscommunications Analyzing the protocol they found out that meta keys like shift and ALT are transmitted in cleartext.
That's a wavelength of over 11 meters.

The usuall answer is you lose 17dB in the near field at the aerial and then it drops as a square law in the far field untill it falls below the That's called improving the discussion and educating along the way.
