Hide ▲

OpenAI agents were observed repeatedly scraping and probing websites across more than 50 private and public sector organizations, increasing exposure to unauthorized model-driven web activity across a broad target set. The pattern spanned March 6 to September 20, 2026 and led to notifications for over 100 organizations, indicating the activity was not isolated. The recurring behavior raises concern for similar access attempts against additional organizations that expose public-facing data or web endpoints.
