Seeing is Not Believing: Breaking the Physical-to-Digital Trust Boundary in Robotics
Researchers show a single ROS 2 environment variable lets attackers inject fake telemetry and hijack robots while spoofing downstream remote attestation.
A pre-built hook loaded via one modified environment variable covertly intercepts and injects both telemetry and control signals before publication in ROS 2, breaking the physical-to-digital trust boundary in multi-robot task handovers. Attackers can also distribute compromised third-party Docker containers and auxiliary tools embedding the hooks. On a physical Franka Emika arm running Secure ROS 2, the attack injects fabricated telemetry in real time with roughly 3 ms jitter and achieved an 87% success rate even against an AI-based detector. Findings were responsibly disclosed to the ROS 2 development team.
- Attack defeats remote attestation by spoofing sensor telemetry in real time
- Supply-chain spread via compromised Docker packages with embedded hooks
- Preserves temporal synchronization and hardware integrity during spoofing
- Demonstrated physically on a Franka Emika robotic arm

In multi-robot collaboration, task handovers rely on downstream verifiers performing remote attestation, which inspects sensor telemetry to ensure a robot's physical behavior strictly matches its assigned task. But can this telemetry be trusted? We show that it often cannot. In this paper, we uncover a severe vulnerability in Robot Operating System (ROS) 2: by modifying a single environment variable, an adversary can execute a pre-built hook to covertly intercept and inject both telemetry and control signals before they are published. Consequently, adversaries can hijack a robot to perform dangerous tasks while spoofing downstream verifiers with synthesized fake telemetry. Worse still, by exploiting the widespread reliance on third-party Docker containers and auxiliary tools, attackers can distribute compromised packages embedded with these malicious hooks to launch such attacks easily. On a physical Franka Emika robotic arm running Secure ROS 2, our attack injects fabricated telemetry in real time with only around 3 ms of jitter, preserving temporal synchronization and hardware integrity while achieving an 87% success rate even against an AI-based detector. We have responsibly disclosed these findings to the ROS 2 development team. We prepared a demo video available at https://youtu.be/ExeiGqUrnhQ.
