Mitt Romney's Email
Okay, obviously the hack on Mitt Romney's email in early June only impacted one guy. But we're giving this one added points for high profile. The email address had been published within an image that appeared in the Wall Street Journal. The hacker then tried to log into the account, reported the password as forgotten, and then correctly guessed that "Seamus," of strap-me-to-the-roof fame, was Romney's favorite pet. Romney's Dropbox account was also accessed in much the same fashion. The exploit called to mind a similar e-mail hack against former Alaska governor Sarah Palin during the 2008 presidential campaign.
