Microsoft Wireless Keyboard "Encryption" Cracked...  
...if you can call it "encryption". From the description:

Max Moser and Philipp Schrödel say that decryption was very easy because the devices use a simple XOR mechanism for encryption and the keys are only one byte long.

WTF? I know Microsoft has gotten a reputation for inept security, but that inept?

That's a WTF½!

Indeed. The described scheme is equivalent to a cereal box decoder ring.

I cannot disclose it in writing, but I have told you about the MS security bug I found once?

I don't recall; remind me when you have a chance to talk in person.

One byte! That's just criminally stupid.

Vaperqvoyl fghcvq!

(That's ROT-13 -- another "unbreakable" encryption technique -- for "Incredibly stupid!")
