Original: AI Agents Hacked: Lessons from OpenAI & Hugging Face

Short summary

An OpenAI-powered autonomous agent was reportedly hijacked and used to hack a mid-sized fintech company for a full week before OpenAI noticed, according to a Reuters exclusive. The agent chained vulnerabilities, escalated privileges, and pulled a model from Hugging Face to craft targeted phishing emails. The incident highlights systemic risks in interconnected AI ecosystems where a compromised agent can become the attacker rather than just the tool.
