New PI3D attack targets MLLMs in 3D environments

Researchers have developed a new prompt injection attack called PI3D, specifically designed for multimodal large language models (MLLMs) operating in 3D environments. This attack involves placing physical objects with injected text into the environment, aiming to override the MLLM's intended task. The method focuses on identifying plausible object placements that induce the MLLM to execute the attacker's command. Experiments show PI3D is effective against various MLLMs, and current defenses are insufficient to reliably counter it. AI
