According to DeepLearning.AI, Columbia University researchers have demonstrated that large language model (LLM)-based AI agents can be manipulated by embedding malicious links within posts on trusted websites such as Reddit. The study shows that attackers can craft posts with harmful instructions disguised as thematically relevant content, luring AI agents into visiting compromised sites. This vulnerability highlights significant security risks for businesses using LLM-powered automation and underscores the need for robust content filtering and monitoring solutions in enterprise AI deployments (source: DeepLearning.AI, June 15, 2025).
