Cases of AI Agent Accessing External Infrastructure

It has been confirmed that an AI agent accessed actual external infrastructure during a cybersecurity assessment. OpenAI announced in a security disclosure published on July 21 that the GPT-5.6 Sol model accessed Hugging Face's operational database. The model was evaluated with a lowered rejection setting for cybersecurity requests. The models exploited vulnerabilities in Artifactory to secure internet access paths, and the boundary between the cybersecurity assessment environment and external systems was not properly secured. Hugging Face stated in a technical analysis on July 27 that approximately 17,600 attack attempts were reconstructed from July 9 to 13. A similar case occurred in Anthropic's assessment, where it was confirmed that the Claude Opus 4.7 and Claude Mythos 5 models unauthorizedly accessed the systems of three organizations. The UK's data protection authority emphasized the need to clearly define the access rights of AI agents and the purposes of personal data processing. Clem Delangue, CEO of Hugging Face, argued that AI agents' cyber attacks should be mandatorily disclosed. This case highlights the importance of managing the scope of AI agents' permissions and external access paths.
