Openai

Dragos and Gambit Security have published details of an intrusion into a municipal water and drainage utility in Monterrey, Mexico, in which a threat actor leveraged OpenAI's GPT models alongside Anthropic's Claude as an AI-assisted operational engine. The January 2026 attack was part of a broader campaign targeting Mexican government organizations between December 2025 and February 2026. According to the report, GPT was used for victim data processing and structured reporting, while Claude handled intrusion planning and tool development, including a 17,000-line Python framework iteratively refined by the model. The incident represents confirmed abuse of OpenAI's models in an active intrusion against operational technology assets, though no specific OpenAI platform vulnerability is implicated. Other sources in the batch concern Anthropic's Claude Chrome extension or unrelated open-source CVE trends and were not used.
