The proposed paper introduces a novel type of Graph Neural Network (GNN) attack, named minimum-budget topology attack, designed to adaptively find the minimum perturbation sufficient for successful misclassification of each node. This approach aims to overcome the limitations of traditional fixed-budget attacks, which can result in either no successful perturbations or redundant ones. The authors develop an attack model, MiBTack, based on a dynamic projected gradient descent algorithm, which effectively solves non-convex constraint optimization on discrete topology. Experimental results demonstrate the efficacy of MiBTack on three GNNs and four real-world datasets, showcasing its ability to successfully misclassify all target nodes with minimal perturbation edges.

The paper proposes a new way to attack Graph Neural Networks (GNNs) called the minimum-budget topology attack. This method tries to find the smallest change needed to make each node in the graph do something different. The authors developed an algorithm, MiBTack, that can do this by adjusting some nodes and edges in the graph. They tested it on four real-world datasets and three types of GNNs and showed that it can successfully trick all the nodes into doing what they want.
