Backdoored robot tries its hand at finger chopping and cat cooking
Researchers devised MuTRAP (Multi-trigger TRojans Attacking Robot Task Planning Systems), a multi-trigger trojan attack technique that injects backdoors into LLMs during domain-specific fine-tuning. The team demonstrated the attack in simulation by causing robots to generate instructions for harmful tasks. The vulnerability arises in the model supply chain when robotics companies rely on third-party trained models rather than developing their own LLMs. The researchers also presented potential defenses and emphasized the need for industry awareness, particularly as many robotics firms depend on external model providers.
Key points
- Backdoor attacks can be injected into LLMs during fine-tuning, compromising robotic task planning
- Attack scenario is practical because many robotics companies use third-party trained models
- Researchers developed MuTRAP defense and demonstrated harmful outputs in simulation
