This is Day 0 of a new world of cybersecurity. Everything changes from here. There will be a time before Generative AI (GenAI) in cybersecurity and a time after it. Over the last two years, GenAI has come on leaps and bounds, and where it once suffered from hallucinations, took racist and bigoted approaches, and often was over-assertive, within ChatGPT 4.5, we see the rise of a friendly and slightly submissive agent, and that is eager to learn from us. This LLM (Large Language Model) approach thus starts to break down the barriers between humans and computers and brings the opportunity to gain access to a new world of knowledge, but, in the wrong hands, it will bring many threats to our current world. There will be few areas, though, that will be affected more by the rise of Gen AI than cybersecurity. Why? Because the minute our adversories use it, we are in trouble. The hacking tools and methods of the past will soon look like the Morris Worm of the past. The threat landscape will see the rise of superintelligence and in providing ways for adversories to continually probe defences and gain a foothold.
