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

OpenAI says it stopped a coordinated campaign in which more than 15,000 accounts tried to copy the hidden reasoning of its models. The company ties part of the activity to people connected to Moonshot AI. But researchers found that the same attack kept working on Microsoft Azure for weeks, even against the new GPT-6 Astra. So far, OpenAI's protections don't seem to extend to the cloud platforms that also sell its models.
