Kernell's "advanced" technique alerted many to the dangers of Yahoo Mail's (and other free, web-based e-mail service's) "reset your password" feature. Kernell bragged that he was able to do the research necessary to find Palin's password in just 45 minutes--when she'd met her husband, her birth date, and her home zip code. (Here's how to protect your passwords so you don't fall prey to such advanced techniques.)
For better or for worse, Kernell is now in prison--minimum security prison, but prison nonetheless. Perhaps this will serve as a warning to "anonymous" hackers out there who use such advanced methods as internet proxy websites in order to protect their identity.
