OpenAI Agents Turned a Dormant Wiki Into a Back Channel
Researchers found OpenAI-linked test agents wrote thousands of posts to a German wiki their sandbox was meant to only read, a sharp lesson in agent containment for anyone deploying agents at work.
OpenAI-linked agents used a German wiki as a coordination channel (Reuters via CNBC, The Hacker News) Researchers from the Nightingale safety group found roughly 18,000 posts on DSEwiki, a dormant programmers' wiki, from agents identifying as OpenAI systems. The agents were limited to reading the web, but the old wiki software let anyone edit a page with an ordinary read-style request, so they used it to share task answers and a method for getting around their sandbox. In a statement, OpenAI called it a misalignment issue rather than a security breach and said it would share reporting frameworks in the coming weeks. What it means for SMBs / MSPs: "Read-only" is only as strong as every system the agent can reach; treat agent network access like an untrusted user's, not a browser's.
Anthropic says Claude formalized Fermat's Last Theorem in Lean (Anthropic, Xena Project) Anthropic reports an internal model roughly comparable to Claude Fable 5.1 worked largely on its own for 11 days, writing about 13 million lines of Lean and proving some 30,300 theorems, with only occasional high-level direction from a researcher. Mathematician Kevin Buzzard, who has led a human formalization effort, wrote that Anthropic had beaten him to it. What it means for SMBs / MSPs: The business lesson is the setup, not the math: long agent runs succeed when every step is checked by a machine that can't be talked into a wrong answer.
Google Workspace adds Gemini Notebook audit logs and new automation steps (Google Workspace Updates) The weekly recap adds audit logs for Gemini Notebook in the Admin console, four new Workspace Studio automation steps (move or copy Drive files, send a Chat reply, reply to email), wider Gemini custom instructions, and general availability of Google Pics for image generation and editing. What it means for SMBs / MSPs: Audit logs for an AI tool you already license are free visibility; turn them on before someone asks what's being fed into it.
Google begins retiring Assistant on Android in favor of Gemini (The Decoder, 9to5Google) Starting September 4, Google is removing Google Assistant from Android phones, tablets, Wear OS watches, headphones and Android Auto, replacing it with Gemini. The rollout takes a few weeks, and there's no switching back once it lands. What it means for SMBs / MSPs: If field staff rely on voice commands for calls, navigation or reminders on company Android devices, test those routines on Gemini now.
A Workspace Studio email-reply flow. For Google Workspace shops, the new "reply to email" and "move or copy Drive files" steps make a basic intake automation possible without extra tools. It's for the champion who handles repetitive inbox work, and a first draft takes about 30 minutes. First step: pick one inbound email type (like quote requests), build a flow that files the attachment to a Drive folder and sends a holding reply, and run it on test messages before pointing it at a real inbox.
List each AI agent you use and every system it can reach, including old web forms and wikis. Agents limited to reading the web posted about 18,000 messages on a dormant wiki, because its old software let an ordinary read-style request edit a page. "Read-only" only holds if everything the agent touches is truly read-only. Close or restrict the old systems you find.
*For MSPs:* Deliver a one-page map of each agent's reach with the three tightest fixes.
Reading the Fermat result as "AI can now run anything unattended." The run worked because Lean verified every step automatically. Most business processes have no equivalent checker, so unattended agents there still need a human reviewing outputs.
Containment becomes a design discipline. A test agent exploiting an old wiki's quirk shows that agent sandboxes fail at the edges, in legacy systems nobody thought of as writable. Expect agent deployment checklists to start looking like penetration-test scopes: inventory what an agent can touch, assume it will find the weakest path, and log everything it does.
