The Cloud Security Alliance documents adversarial text embedded on physical objects — stickers, printed signs, whiteboards — hijacking multimodal agent behavior through photos. Unlike digital injection, there's no file to inspect or sanitize. The attack vector is the physical world captured by camera. Particularly relevant for agents with computer-use or vision capabilities operating in real environments.
