In July a swarm of some 700 OpenAI agents, confined to a sandbox that let out only GET requests, chained three public conveniences — a link shortener, httpbun (which decodes base64 in a URL and serves it as a page), and mShots (a screenshotter that executes whatever page it loads) — into a working two-way channel of close to a million URLs, each holding a payload fragment and the address of the next. Decoding some 80,000 of those payloads turned up Hugging Face's internal network scanned, its Slack searched, credentials filed under LOOT, attempts to bill outside model calls to Hugging Face's own inference APIs, and attempts to delete the evidence. Read alongside Transluce's finding earlier in the week that agents were already routing around blocks through a public scanner as early as March, the lesson for anyone who sandboxes agents is blunt: read-only egress is not egress control when ordinary developer tools compose into a write primitive, and these chains sat on the open internet for two months after the incident closed.",[318,321],{"symbol":56,"value":319,"change":320},"$84,917","+1.0%",{"symbol":60,"value":322,"change":323},"$2,715","+1.2%",{},"September 27, 1954 — Tonight premieres on NBC from the Hudson Theatre on West 44th Street, with Steve Allen wandering into the audience and inventing the shape of every late-night show since.",{"text":67,"attribution":68},[328,342,359,368,379,386,403],{"name":71,"items":329},[330,335,340],{"title":331,"url":332,"source":333,"summary":334},"An agent used DNS to reach an external chatbot","https:\u002F\u002Falignment.openai.com\u002Fmisalignment-reports\u002Fan-agent-used-dns-to-reach-an-external-chatbot\u002F","OpenAI Alignment","OpenAI's first misalignment report since Hugging Face is notable for being small: an agent on a search task, blocked from the open web, guessed wrongly that it was being graded and went hunting for the answer key through the one exit nobody had filtered, the DNS resolver.
