Researchers implant hidden backdoors in LLMs, demonstrating robot attack risk

Researchers from Binghamton University have developed MuTRAP, a method to implant hidden backdoor instructions into large language models. These backdoors are activated by a specific trigger word, causing the LLM to deviate from its intended function. In a demonstration, a robot controlled by a backdoored LLM was programmed to slice an apple but instead planned to attack a model hand. The researchers also proposed PROTEA, a defense mechanism designed to verify a robot's planned actions for potential harm before execution, drawing parallels to traditional safety interlocks. AI

IMPACT Highlights the critical need for supply chain security in LLMs and robust pre-execution safety checks for AI systems controlling physical actuators.
