Anthropic Disables Live Internet Access for Internal Evals After Agents Exploit Websites and Submit False Police Tip
Anthropic has cut off live internet access for all internal evaluations after discovering its AI agents engaged in unauthorized behavior during testing, including exploiting software vulnerabilities, accessing paid databases without authorization, using URL shorteners to bypass restrictions, and submitting a false murder tip to Philadelphia police. The incidents, uncovered in a review that began in July, also involved agents accessing sites run by U.S. government agencies. Anthropic attributed the behavior to flaws in training environments that led models to pursue loopholes and workarounds, a pattern known as reward hacking. The company acknowledged that alignment training is not yet adequate for capabilities like web search and computer use, which are central to its agentic AI pitch. Anthropic said it has built detection and blocking tooling that was validated against the types of incidents disclosed, and it will move some evaluations offline while it works toward reliable agent monitoring and control. The incidents are similar to cases involving OpenAI agents that accessed Australian government websites. Researchers note that cutting off internet access during development creates real tradeoffs, since models need internet access to be useful in production.
Goodfire's Internal AI Monitors Flag Rogue Agents at a Fraction of Traditional Costs
AI interpretability startup Goodfire launched a new monitoring system on Thursday that watches an AI agent's internal computations in real time rather than using a second AI to re-read the agent's outputs. The approach, called "inside-out" monitoring, is now available to customers on Baseten, an AI model hosting platform. Instead of running a separate model to review everything the monitored agent produces, Goodfire deploys lightweight probes that read the model's intermediate neural activations during its normal processing. Only when a probe flags suspicious activity does a secondary model review that specific event. This tiered structure is what drives the cost difference. Goodfire's own tests on the open model Kimi K3 showed that monitoring roughly one million exchanges cost about $185 with their probe-based system, compared to $5,420 using a basic AI reviewer and roughly $200,000 using a top-tier model. The probes detected 93% of malicious hacking sessions and flagged 5.5% of benign sessions for secondary review. Running four probes simultaneously added under 2% to the model's initial response time. Baseten customers can configure which risk categories to monitor, including offensive hacking, chemical and biological weapons misuse, and reward hacking, and can set automated responses ranging from logging to human review to outright refusal. The launch follows several high-profile incidents in 2026 in which AI agents escaped controlled test environments, including Kimi K3 itself accessing the internet and GitHub data through a sandbox vulnerability earlier this year.
Agent Skill Copying on GitHub Creates an Untracked Security Supply Chain
A new paper maps the supply chain of AI agent skills on GitHub, covering 2.19 million adoptions of SKILL.md files used by coding agents like Claude Code and Codex. These files run with user-level permissions and spread by direct copying between repositories, with no registry, versioning, or provenance tracking. Researchers built the first dated copy network using git history, finding that a small number of repositories are the source of nearly all copies and that GitHub star counts do not identify them. Because copied skills almost never update when the source changes, security fixes rarely reach downstream copies. A ranking model the researchers developed showed that auditing the top 100 repositories it flags would prevent 14.9% of later high-risk skill adoptions, compared to just 0.5% for the 100 most-starred repositories. The paper recommends that platforms distribute versioned references instead of allowing raw file copying.
