Robot safety under attack: are your controls keeping up?

TL;DR: A robot can execute approved commands exactly as intended and still produce an unsafe outcome if sensors, messages, or other inputs are manipulated, according to VicOne research, because cybersecurity changes the odds and creates repeatable hazardous conditions. The governance gap is that expected operation is not the same as a validated safe state when the environment can be adversarially altered.

Key questions

Q: What should teams do when a robot behaves as expected but may still be unsafe?

A: Treat the event as a safety validation problem as well as a security problem.

Q: Why do manipulated inputs create more risk for robotics than ordinary software bugs?

A: Because robotics safety depends on physical context, not just code correctness.

Q: How do security teams test whether an exploit changes robot behaviour?

A: Use reachability analysis to confirm the attack path, then reproduce the exploit inside the same simulation environment used for safety testing.

Practitioner guidance

• Build adversarial cases into robot safety testing Load manipulated sensor feeds, spoofed commands, adversarial images, and compromised component states into the same simulation environment used for functional safety validation.
• Baseline fleet behaviour and watch for divergence Compare robots operating in the same fleet so that unexpected drift, anomalous motion, or sensor-state changes become investigation triggers rather than late discoveries.
• Predefine safety-validated fallback modes Authorise degraded behaviours such as reduced speed, restricted motion, or task suspension before deployment so the robot can respond safely when context becomes untrusted.

Bottom line: A robot can obey an authorised command and still create a hazard if the surrounding context has been manipulated.
