this was my first offensivecon and what a blast! had so much fun catching up with old friends and making new ones - not to mention the level of technical content and convos, what an awesome community :)

I feel like this is a good time to remind everyone: we’re hiring! Disclaimer: OffensiveCon prep involves moving boxes, laying down kilometres of cable, and a liver of steel… but the rest of the time, you’ll be free to focus on research 😉 @binary_gecko offensivecon
