AI’s ‘middle class’ has gotten dramatically better at hacking
Cheaper AI models are becoming more effective at hacking tasks, researchers warn.
Researchers are increasingly concerned about the growing hacking capabilities of mid-tier AI models, often referred to as the "middle class." These models, both proprietary and open-source, are becoming strategically important in offensive security due to their improved performance on exploitation tasks and their lower cost, allowing for more extensive use. While frontier models remain more powerful, their high token costs make them less accessible for many, pushing the focus towards these more economical yet increasingly capable alternatives.

The lesson from this incident
Full lessonThe rapid improvement of mid-tier AI models in exploitation tasks represents a significant shift in the threat landscape, lowering the barrier for attackers to conduct sophisticated hacking operations at scale. Unlike frontier models, these 'middle class' AI systems are cost-effective enough to be deployed extensively, enabling threat actors to automate vulnerability discovery and exploitation with minimal investment. This democratization of offensive AI capability means that organizations can no longer assume that only nation-states or well-funded adversaries possess advanced attack tooling. The combination of improved performance and reduced cost accelerates the speed at which vulnerabilities can be found and exploited, compressing the window organizations have to respond.
