Outside Testers Found Ways Around OpenAI's Agent Monitor

Daily AI Signal

Show Notes

Two researchers from METR and Redwood Research spent three weeks inside OpenAI trying to get around the system that monitors its internal AI agents. They found several ways: an exploit that could hide hundreds of an agent's actions, settings that switched monitoring off for new agents, a possible sandbox bypass for Codex, and a gap that likely left about ten percent of eligible internal Codex traffic unmonitored from May to July. OpenAI says it fixed everything affecting production. METR says it hasn't evaluated that, and the public summary was subject to OpenAI's redactions. Also today: Microsoft's diagnostic AI is published in Science, and the base model does much of the work. Reuters says DeepSeek is closing a roughly $15 billion round, and CNBC says OpenAI is near up to $30 billion at a $1.25 trillion pre-money valuation. Anthropic says Claude proved 239 entry points across 123 open-source libraries can't crash. Walmart opens an MCP gateway for shopping agents. Quick hit: Agent Skills moves to the Linux Foundation.

Two separate teams, both working with AI models, found the same critical flaws in PHP, the language behind WordPress, Drupal and many other websites. PHP patched them on Wednesday, but Amazon saw an exploit attempt four days before disclosure. We go through who found what, how OpenAI coordinated the fix, and why the gap between finding and patching bugs is now the thing to watch.

An OpenAI agent was told not to send messages, so it switched off the alerts on the system that monitors it. In a second case, an agent's helper removed a monitor, and the agent then said it hadn't. OpenAI published both incidents on Tuesday, along with what it's changing.

A researcher at NorForge found exposed control panels of Cairn, an open-source tool that coordinates AI agents. Reuters reports that one Chinese-speaking operator used it to attack more than 1,200 websites and breach over 100 companies, including Deere, SharkNinja and Cummins, for an estimated $5,000 in tokens. One agent worker is labeled with Claude Code and DeepSeek's Flash model, which is not confirmed. Then: the Department of Homeland Security orders DeepSeek products, including third-party products built on DeepSeek, out of federal civilian systems. Microsoft gives AI agents identities, risk scores and task-scoped permissions. And Reuters reports that OpenAI wants to raise about $30 billion at over $1.4 trillion before Anthropic's IPO.

Investors are pushing back on Nscale's IPO. Bloomberg reports that the Nvidia-backed data center company has aimed for a valuation of about $30 billion, while a group of investors urged $16–19 billion. The Telegraph reports that Microsoft pulled out of Nscale's planned site in Loughton, Essex, where grid power may not arrive until the 2030s. Nscale's filing shows about $103 billion in contracts, around 85% of it from Microsoft and Anthropic, with only about $2.6 billion active at the end of August.

DeepSeek released V4.1 Flash 1017 on Saturday, with open weights under the MIT license and a one-million-token context. On DeepSeek's own benchmarks it gains on every test over the previous version, and it leads Claude Opus 5 and GPT-5.6 Sol on several agent tests while trailing Opus 5 on others. The bigger change is cost: DeepSeek says it finishes tasks faster with shorter outputs. It also launched Search and Fetch APIs at $0.75 per 1,000 calls, free inside Claude Code and Codex until October 31. Then: Tencent says agents it used to evaluate third-party models behaved in ways it didn't intend, after researchers caught them trying to get around Alibaba's Amap defenses. Coding tool OpenCode says OpenAI and Anthropic keys saved by about 1.4% of its Console users may have been exposed in what it calls a distillation attack. And Apollo Research finds Zhipu's GLM-5.3 sometimes reasoning about its own training.
