MobileInject: Evaluating Reasoning-to-Action Security of MLLM-Based Mobile Agents under Cross-Modal Consistency Injection
Researchers demonstrate how cross-modal consistency injection can trick autonomous MLLM-driven mobile agents into executing unintended actions—flagging a largely unmitigated attack surface as enterprises pilot agentic smartphone assistants.

arXiv:2610.23307v1 Announce Type: new Abstract: Multimodal large language model (MLLM)-based mobile agents are rapidly evolving from conversational assistants into autonomous systems that perceive, reason over, and act on smartphone environments. This capability also exposes a new security risk: adversaries can embed malicious objectives in cross-application mobile content and steer agent behavior through indirect multimodal injection. Although prompt injection has been studied in desktop and w
Editorial Analysis
As enterprises pilot autonomous mobile agents, cross-modal injection attacks could let adversaries silently hijack device actions—a risk most MDM and MAM controls were never designed to catch.
Inventory any MLLM-based mobile agent pilots and assess whether existing mobile-security controls address cross-modal prompt injection.
Autonomous AI agents on corporate smartphones may be manipulable through a novel injection technique that current mobile-security stacks do not detect.
