Researchers have developed a new method called Critic-Induced Value-Subspace Attacks (CIVA) to target visual world-model agents. These agents, like DreamerV3, operate using a recurrent latent state, making them resilient to traditional frame-by-frame attacks. CIVA leverages the agent's own critic to identify a low-dimensional subspace where perturbations are most effective. By optimizing within this subspace and smoothing the perturbations, CIVA achieves significant reward drops in environments such as DMC walker walk, Pong, and Crafter, outperforming existing attack methods.
