University of California researchers warn that some third-party AI large language model routers have security risks, which could lead to crypto assets being stolen. Testing found multiple routers injecting malicious code to steal credentials. Developers are advised to avoid transmitting private keys through AI agents and to strengthen security measures.

A study by the University of California reveals security vulnerabilities in the supply chain of large language models (LLMs), especially malicious man-in-the-middle attacks that third-party routers may carry out. The research found that 26 routers injected malicious commands to steal credentials and sensitive data. Users have difficulty noticing the boundary between credential handling and theft, and the “YOLO mode” further increases security risk. The study recommends that developers isolate sensitive operations and choose router services with transparent auditing to strengthen protection.
