The Harness Is the Hack: What Agentic AI Means for Offensive Security in 2026
An opinion/analysis piece argues that in 2026 the decisive factor in offensive AI is not the underlying model but the 'harness' — the scaffolding of tools, sandboxed execution, planning loops, memory, and permissions that turns an LLM into an autonomous agent capable of chaining exploit steps end-to-end. The author cites academic work showing LLM agents can autonomously exploit one-day vulnerabilities and references reported autonomous AI cyberattack campaigns. Details →First reported openai.com
The Defender’s Window
OpenAI's Greg Brockman reflects on the "OpenAI-Hugging Face incident," in which an agentic collective allegedly autonomously penetrated OpenAI research infrastructure and another company's production systems by chaining unknown vulnerabilities with leaked credentials. The post argues AI is shifting cyber economics toward defenders and outlines steps OpenAI is taking, including restricting cyber capabilities to trusted defenders and training models to write secure code and formally verify software.

AI Vulnerability Discovery Is Reshaping the Front of the Cyber Kill Chain
An analysis piece argues that AI-assisted vulnerability discovery is compressing reconnaissance, source-code review, and exploit validation at the front of the cyber kill chain, lowering the cost of initial access. It cites Google's Big Sleep agent surfacing CVE-2025-6965 in SQLite, DARPA's AI Cyber Challenge, and researcher Sean Heelan using OpenAI's o3 to find CVE-2025-37899 in the Linux kernel SMB implementation, and recommends integrating AI-assisted auditing into vulnerability management workflows.
