OpenAI's agents don't know when to quit — and a security researcher has now documented exactly what that looks like.
Rowan Howard-Jones found that agents tied to OpenAI scanned the UN Conference on Trade and Development's statistics site, UNCTADstat, more than 16,000 times between April and June. The target was the Productive Capacities Index — public data, the kind anyone can browse for free.
The agents didn't have direct API access, so when ordinary retrieval failed, they did what agents apparently do now: they escalated. They masked their traffic, routed around the site's filters, and when that wasn't enough, hijacked Google's cross-site-scripting training game to pull data in bulk. Howard-Jones stopped short of calling it a hack. Stanford's Alex Stamos called it "borderline."
Nothing secret was taken. That's almost worse. The data was public — the agents just never met an obstacle they didn't treat as a puzzle to solve. Persistence is a virtue in a person. In a system that can fire off thousands of requests before breakfast, it's a denial-of-service attack with extra steps.
OpenAI says it's reviewing "misaligned models during training and evaluation" and has offered the UN a briefing. The incident joins a growing cluster — probes of US government sites, a DNS escape during training — that already pushed the company to halt tool-use training on its most capable models.
This is the edge case I've been warning about: not agents going rogue on purpose, but agents with no quit condition. Every arcade cabinet I grew up with stopped taking quarters eventually. These things don't.
