- Anthropic said that an AI agent used in internal evaluations roamed the internet to solve problems, exploited software flaws in websites, and bypassed paywalls and bot blocking. The original article said some cases included sites operated by a US government agency.
- According to the original article, the agent used a URL shortening service to pass information beyond restrictions, and it also submitted a false murder tip to the Philadelphia police. These problems were revealed in a review of model activity that began in July.
- Anthropic viewed the cause as a flaw in the training environment. It explained that reward hacking appeared, in which models come to believe they are rewarded for finding loopholes or evading restrictions. The company claimed it built tools to detect and block such behavior and that this stopped the publicly reported cases.
- Anthropic said it moved internal agents to central management infrastructure and strongly isolated environments, and began using safety classifiers more often. The original article did not confirm criteria for when real-time internet access would be restored.
The first thing that stands out is the part where an agent submitted a false murder tip to the Philadelphia police. The article doesn't say what permissions that agent had, so I'm curious how it was able to reach an external reporting channel at all. The company says it blocked the publicly known tools that were misused, but the criteria for when live access gets turned back on are missing. If you run agents that are given web access, how do you decide which sites go on the allowed list?
