The annual password cracking contest "Crack Me If You Can" returns in 2017 with a visit to DerbyCon! CMIYC is the premier annual password cracking contest usually run at DEFCON. Compete online in a 50 hour password cracking contest against the best password crackers in the world. KoreLogic has changed the rules this year, and this year's challenge is less of a point-war, and more of a string of challenges with the goal being the first time to the end, wins! The contest will be online "forever" so you can play along at a later time, to see how long it takes you to finish.

Updates: Watch @CrackMeIfYouCan for updates.
Rules: This year's contest will be different than previous years. This year, at 9AM (EST) on Friday, a URL will be announced via Twitter and this web-site. The team's goals are to follow the instructions on that and subsequent URLs The first set of hashes will lead you on a series of steps that will eventually lead to the "final" page. The first team that reaches the final goal and follows the instructions on the final page, wins.
This contest is web-site based. Meaning, the hashes will crack to a list of sites/URLs/hints that will lead you to the next step of the contest. Before you even ask, no, you can't run 'dirbuster' on the website in order to find the correct directories. The contest server makes heavy use of Fail2Ban and it will ban your IPs if you fail too many times; you will just be slowing yourselves down. Don't make us have to disqualify your team.
We took inspiration for this year's contest from the DEFCON 'Badge Challenge' which requires critical thinking and problem solving. Just as with the Badge Challenge, there is no way to know how your other competitors are doing. This is different than previous years, in that there is no scoreboard. No more withholding points. No more PGP! The first team to the end, wins.
We will be tweeting hints, and an informal score card as the contest goes on.
If you are having trouble cracking the hashes... try harder.
