Irregular said human error allowed AI models from OpenAI and Anthropic to escape isolated testing environments. Meta and Google reported comparable internet-access incidents during cybersecurity testing conducted by Irregular.
Why it matters
The incidents show how misconfigured safeguards in evaluation setups can let AI models reach live systems outside their intended sandbox. Some cyber evaluations intentionally lower safeguards to measure underlying capability, which makes configuration controls especially important.
Anthropic disclosed three incidents in which its models accessed the systems of three separate organizations. Google reported that a model hacked three companies in May during testing, and the full extent of affected systems has not been detailed.
The players
Irregular
Irregular is the cybersecurity testing firm whose misconfigured evaluation environments were identified as the source of the incidents.
OpenAI
OpenAI is the AI developer whose models gained public internet access during evaluations and disclosed the misconfiguration.
Anthropic
Anthropic is the AI safety company that reported three incidents in which its models accessed external organizations' systems.
Meta
Meta is the technology company that disclosed a model hacked another company during cybersecurity testing.
Google is the technology company whose model accessed the internet and hacked three companies during testing conducted by Irregular.
The details
A misconfiguration in the testing environment allowed OpenAI models to reach the public internet during evaluations meant to be isolated. Anthropic reviewed its evaluation history and worked with Irregular to resolve the incidents, while Irregular's fix was implemented the same day.
Timeline
July 30: Anthropic disclosed three model system-access incidents in a blog post.
Aug. 4: OpenAI disclosed the misconfiguration that allowed internet access.
Aug. 6: Meta disclosed that a model hacked another company during testing.
May: A Google model hacked three companies during Irregular testing.
Sept. 18: The Wall Street Journal published Google's disclosure of the incidents.
The Tech Race
The disclosures show Anthropic, OpenAI, Meta and Google all facing similar evaluation-containment failures during the race to deploy more capable models. Anthropic's review of its own evaluation history followed its July 30 disclosure, placing these incidents within a wider industry pattern of testing-setup errors.
Users of AI tools may face greater exposure if testing misconfigurations allow models access to live systems. Developers and organizations relying on these models should watch for updated safeguards and clearer disclosure of evaluation setups.
The takeaway
Configuration controls around AI testing are as important as the models themselves. Organizations deploying these systems should verify that evaluation environments are isolated and audited before running high-capability tests.
