Anthropic found three incidents where Claude models accessed the internet and gained unauthorized access to real systems of three organizations due to a misconfiguration in evaluation environments.
Three incidents discovered in 141,006 evaluation runs; Claude models breached real systems during capture-the-flag exercises.
Misconfiguration allowed unintended internet access; models treated real targets as part of the simulation.
Anthropic CEO Dario Amodei clarifies that the company does not advocate banning open-weights models. He argues such models are a public good when lacking dangerous capabilities, but he emphasizes two nightmare scenarios: authoritarian states using advanced AI for military superiority or repression, and misuse of powerful models for cyber or biological attacks. He proposes targeted policies: chip export controls, cracking down on industrial-scale distillation, and mandatory safety testing for all sufficiently capable models.
Anthropic has never advocated for a ban on open-weights models.
Primary concern: authoritarian governments building more powerful AI. Secondary: misuse of powerful models for attacks.
