📌 Key Takeaways
- Behavior‑targeted attacks aim to control an RL agent’s actions via adversarial state observations.
- Previous techniques depended on white‑box access to the victim’s policy, limiting their applicability.
- The proposed method uses imitation learning to generate effective attacks in a black‑box setting.
- The study discusses countermeasures against such behavior‑manipulation attacks.
- The work underscores the growing importance of security considerations in deep RL deployments.
📖 Full Retelling
Researchers in reinforcement learning security have released a study in June 2024 that introduces a novel black‑box attack technique for manipulating the behavior of deep RL agents. The work, published on arXiv (2406.03862), addresses the limitation of prior behavior‑targeted attacks that required white‑box access to the victim’s policy. By employing imitation learning, the new method can craft adversarial state observations to steer the agent toward the attacker’s goals without knowledge of its internal policy, thus broadening the threat landscape and highlighting the need for robust countermeasures.

Abstract: This study investigates behavior-targeted attacks on reinforcement learning and their countermeasures. Behavior-targeted attacks aim to manipulate the victim's behavior as desired by the adversary through adversarial interventions in state observations. Existing behavior-targeted attacks have some limitations, such as requiring white-box access to the victim's policy. To address this, we propose a novel attack method using imitation lear
