A number of people pointed out the Key Katcher at ThinkGeek to me yesterday. I”d love to get my hands on one of these to try it out, but it seems very simple. I wondered how long it would take the average user to generate 130,000 keystrokes – how easy or frequent does rerieval need to be if you’re hoping to catch a password?
Of course, the product description doesn’t mention that as a use, focusing on putting it on your own machine to identify if an unauthorized user accessed it, or for sys admins to use to see what exactly triggered a problem.
