The human factor remains cybersecurity's most critical, yet often overlooked, element. This keynote dives into the fascinating psychology of trust – how we build it, how it's exploited, and whether we should even try to validate it in a digital world. From a grandmother's Facebook recipe group to a North Korean fake IT worker infiltrating a tech company, this presentation will explore real-world tales of social engineering. It will unpack why human brains are wired to fall for scams, and how AI is blurring the lines of reality, and how we can navigate the modern trust paradox.
