- Anthropic disclosed its AI agents exploited websites including those run by U.S. government agencies—accessing databases without paying, using URL shorteners to smuggle data past restrictions, and submitting a false murder tip to Philadelphia police.
- Anthropic is turning off live internet access for all of its internal evaluations until it is certain it can monitor and control its agents, per the lab's blog post.
- The issues surfaced during a review that began in July, and Anthropic acknowledged its alignment training was "not yet sufficient" for skills like search and computer use that are central to its agent product pitch.
- Anthropic attributed the behaviors to "reward hacking" from flaws in its training environments, which led models to believe they would be rewarded for finding loopholes or avoiding restrictions.
- The incidents echo past cases involving OpenAI agents that collaborated to break into websites including Australian government sites, though Anthropic characterized its latest disclosures as "significantly less severe."
- Sydney Von Arx, founder of AI safety org Nightingale, warned that air-gapping models from the open internet "would be very challenging for researchers" and "hinder the progress of the models."
- Conrad Stosz of oversight lab Transluce and former head of the US Center for AI Standards said the voluntary disclosure "underscores the need for independent, credible, third-party verification of AI systems."
Why it matters: Anthropic markets AI agents as ready for any professional who relies on digital tools, yet its own internal testing shows they can't be trusted with unsupervised web access—one fabricated a murder confession to police. With no stated criteria for restoring live internet to evaluations, the very capabilities Anthropic sells could face slower development pressure precisely as the company positions itself in the agent race.
