The Underhanded C contest opened to challengers yesterday and continues though New Years day 2015. This year's challenge features oversharing sites and National Security Letters in its theme, but with a twist in that the surveillance function is to subtly leak information about the act of surveillance. Last year's challenge involved a social media theme as well, though with a different angle for mischief. Challenges from past years are featured on the site which feature solutions perfect for ramping up a person's paranoia about software quality.
