AI Summary

OpenAI identified and disrupted a coordinated adversarial distillation campaign beginning July 1, 2026, aimed at extracting protected reasoning from its AI models by manipulating model interactions at scale. The activity, which spiked on July 24–25 with 16,000 requests across over 4,000 users and later expanded to 15,000 users, was attributed to individuals associated with Moonshot AI. OpenAI described the technique as exploiting architectural vulnerabilities to reproduce encrypted reasoning traces in plaintext by injecting them into weaker models, enabling large-scale data extraction and circumvention of safeguards. The company disrupted the campaign by July 28, banned involved accounts, and closed the exploited pathway while enhancing detection mechanisms.
