Four days. A spare $500 mini PC from Microcenter. An open-source quantized model running on 512 MB of VRAM. And by Thursday morning, an autonomous AI agent named Jenkins was finding vulnerabilities, chaining exploits, gaining root, and maintaining persistence — entirely on its own, with no human in the loop. In Episode 11 of The GIST of Govt IT, Brian and Sean are joined by Marlin McFate, Federal CTO and CISO at Cohesity to dig into the experiment Marlin documented on his new Substack, Peripheral Tech. Marlin walks through the architectural choices that made Jenkins possible — the "discussion skill" approach to working with agents like colleagues, the orchestrator-subagent model, the safety capability files that proved more effective than external guardrails — and why the implications go far beyond "Mythos changed everything." The conversation digs into the real thesis: the barrier to nation-state-grade offensive cyber didn't just fall — it fell years ago, and most organizations are still spending 80% of their cybersecurity budget trying to prevent attacks rather than recover from them. Brian, Sean, and Marlin unpack the digital jump bag, the minimum viable agency concept, why finding the last clean backup is "a bad lie" the industry has been telling for years, and what Cohesity's RAG-enabled secondary data approach means for agencies trying to feed AI without standing up a fifth copy of their data. Plus, AI agents throw fits and take on personalities for their own.
