New adversarial attack targets GNN-based anomaly detection in sensor networks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed BETA, a novel indirect adversarial attack designed to compromise graph neural network (GNN) based anomaly detection systems in sensor networks. This attack method allows an adversary to perturb readings from a limited set of nodes, excluding the target sensor, to manipulate anomaly detection outcomes. BETA utilizes a graph explanatory model and a centrality-based pruning strategy to identify influential nodes for perturbation, demonstrating significant effectiveness in reducing the F1-score of existing GNN detectors by an average of 36.07% to 50.45% across real-world datasets.
