New adaptive attack targets wireless control systems using critic disagreement

Researchers have developed a new adaptive reward poisoning attack called Disagreement-Guided Reward Poisoning (DGRP) that targets learning-based wireless control systems. This attack specifically exploits disagreements between dual critics in Soft Actor-Critic agents, particularly in high-uncertainty states. By corrupting reward signals, DGRP distorts value estimations and leads the agent's policy toward suboptimal actions, significantly degrading performance in RIS-assisted networks. AI
