Yianna Paris is a Senior Offensive Security Consultant and Trainer based in the Netherlands who lives at the intersection of software engineering and security — with a soft spot for hardware. She specialises in digital exposure, threat hunting and getting hands on by breaking systems: mapping real attack surfaces, finding what's leaking, and working with dev teams to fix it before someone else does. She particularly likes finding interesting logic bugs with secure code review and proving exploitability by hacking software. She doesn't work well with checkbox compliant - proving exploitability and risk is key. Helping organisations understand where they're vulnerable and how to secure their pipelines is what makes breaking that software the most fulfilling. She's spoken and run workshops at DEFCON, and has a particular obsession with wireless protocols, cloud and embedded systems, and the surprising number of things you can do with cheap hardware and a bit of patience. If it transmits a signal, she's probably tried to intercept it. Previously she lived in Australia where she also worked as a software engineer.
