This is a special tutorial write-up authored by Deja Security Consultant Atanas Kirilov, who built the CubCon 2018 badge.
CubCon was a brand-new event at DEF CON, developed with the intent to bring beginner and experienced hackers together and build up the community, as well as to pass along career tips and lessons learned the hard way.
I’m one of the four organizers who ran the event, and the purpose of this post is to illustrate how I helped plan it with the development of a challenge badge.

“The skills developed by gaming could be arguably summarized as practice obsessing over digital problems. I think anyone who has seen both a hacker and a gamer obsessing over something can immediately understand the relationship.

“People are going to be trusting us with potentially their life-savings. It’s a precarious case when you’re handling people’s money…There are a lot of potential attack vectors we’re dealing with, so we wanted to make sure we’re covered for most if not all of those risks…Having someone audit [the platform] was pretty key.” -Status COO Nabil Naghdy
“Companies want to work with Deja because they want people who think outside the box and break their stuff...Deja is working on securing some of the largest software platforms in the world. That’s pretty cool.”
“You know it’s good work when you’ve got people challenging you in different areas,” she said. “It shows they have done a thorough analysis. These require some thought from you. An audit that doesn’t challenge, doesn’t provide value.”
