OpenAI says it stopped a campaign to steal its models' reasoning, but the trick still worked on Azure

Intel Summary
OpenAI reported stopping a coordinated campaign involving over 15,000 accounts attempting to extract the hidden reasoning processes of its models, linking part of the effort to individuals connected to Moonshot AI. However, researchers discovered that the extraction technique remained functional on Microsoft Azure for weeks, including against GPT-6 Astra, indicating OpenAI's defensive measures were not mirrored on third-party cloud hosting platforms.
Why It Matters
The persistence of the extraction vulnerability on Microsoft Azure highlights significant security parity gaps between direct model API endpoints and partner cloud deployments. For enterprise buyers and defenders, this divergence demonstrates that vendor-level guardrails and anti-distillation defenses do not automatically protect downstream managed cloud instances, leaving proprietary model outputs and chain-of-thought logic vulnerable across partner infrastructure.
