Using OpenAI\u2019s GPT-5.5, offensive tooling, and structured operational guidance, the researchers were able to complete an end-to-end attack chain, from external access to domain administrator privileges. \u201cThe fastest successful execution achieved its objective in 40 minutes,\u201d they said.<\/p>\n<p>Across the six attack scenarios tested, a consistent pattern emerged: The strongest outcomes were not explained by the model alone. Instead, success depended on the interaction between frontier-model reasoning, agent platform-enabled tooling, operational context, and human-defined objectives.\u00a0<\/p>\n<p>Small improvements in direction, context, tooling, and orchestration dramatically improved outcomes, the researchers wrote, while autonomous execution without reliable tooling proved significantly less effective.\u00a0<\/p>\n<p style=\"padding-inline-start:40px\"><em>\u201cOne of the clearest lessons was that the stack mattered more than the model.\u201d<\/em><br \/>\u2014Cato researchers<\/p>\n<p>Here are the key takeaways from their research on agentic AI-enhanced attacks.<\/p>\n<p><strong>[ Join webinar:\u00a0<\/strong><a href=\"https:\/\/www.reversinglabs.com\/events\/autonomy-not-autopilot-agentic-soc\"><strong>Autonomy, Not Autopilot: Talking Agentic SOC<\/strong><\/a><strong> ]<\/strong><\/p>\n<h2 id=\"cybersecuritys-big-shift\">Cybersecurity&#8217;s big shift<\/h2>\n<p>Li Zhao, a principal strategic services consultant at Black Duck Software, said the Cato research shifts the discussion from AI\u2019s ability to generate individual exploits to its ability to orchestrate complete attack workflows.
