All Day Games

Are you ready for some mid con entertainment! . Throughout Thursday & Friday play a variety of games in the Exhibitor Hall. Hosted @lintile . Get something wrong, pay the penalty. Not for the easily offended or those without a sense of humor and a strong alcohol tolerance.


Forensics Challenge – CTF

Go to the contest booth and pick up details. There are sure to be things for all skill levels. Teams up to 4 allowed.

Car Hacking Village

Brought to you by CANBUSHACK team, conference attendees will get hands on experience in hacking automotive technologies. Not only will this village be openly available to the public, but there will also be a huge opportunity to learn the art of hacking vehicles. There is no formal agenda setup, rather a table with a few automotive components and benches for attendees to interact with.


We’re back, baby! It’s your favorite no-hacking hacking event, the Open Source INTelligence Capture The Flag, coming to you live from Grand Rapids, Michigan.

Think you have what it takes to track down real flags on real targets? That’s what the OSINT CTF is all about. No hacking of social media accounts, no clever vishing campaigns, just open source deep dives into the lives of complete strangers who have graciously agreed to be our volun-targets for the contest.

Your team can sign up in person or online (here) any time before Friday morning. The contest will begin Friday morning and end with a panel discussion Friday afternoon. There might even be some candy and prizes thrown in along the way.

Hosted by CG Silvers Consulting.
