The great thing about contributing to OWASP Cornucopia is that you can immortalize yourself. So though I can’t escape this mortal world, I will survive as a threat actor in
@threatdragon.bsky.social and hopefully end up as a bug in your issue tracking system where I will haunt your waking hours.

When ever a DM talks about replacing developers with AI. Remember that it’s not a novel idea and that you probably have heard it before told slightly differently.

How do you get your dev team to shift left for real?

Shift-left doesn't start with scanning code for vulnerabilities; it begins with designing it.

Play yourself secure with OWASP Cornucopia Website Edition v2.2!

The quality was horrible, I used 3 days to get it all done, I had to hid from my boss the fact that I was laying off work to do it and when I was done, people were cutting themselves on the razor sharp card ages. Without you, we would still be sitting their with our scissors and laminate machines.

Thank you Simon Gibbs and Devika Gibbs for bringing games to cyber security.

When I started OWASP Cornucopia I couldn’t find the physical cards and had to print them out on a HP Instant Ink printer, cut each out, laminate the 82 cards and cut them out again.
