Toward Subspace-Perturbed Trajectory-Aware Backdoor Attacks in Deep Reinforcement Learning

Deep Reinforcement Learning agents are in- creasingly used in safety-critical domains but remain vulnerable to stealthy backdoor attacks. Existing outer-loop attacks face a trade-off be- tween perceptual stealth, poisoning efficiency, and value-function consistency, often making the at- tack ineffec…
