### Key Quotes
> While this is encouraging, it does not mean we’re seeing less exploitation in the wild. It does mean we are seeing fewer 0-days exploited in the wild. This makes sense, as AI is better at reversing patches than it is at finding and exploiting bugs in closed-source software.
> — Dustin Childs, Head of threat awareness at TrendAI’s Zero Day Initiative
