arXiv:2605.16815v2 Announce Type: replace-cross Abstract: Graph neural networks (GNNs) have achieved remarkable success in relational learning. However, their vulnerability to graph backdoor attacks (GBAs) poses a significant barrier to broader adoption in high-stakes applications. Despite recent advances in graph backdoor defense (GBD), existing methods primarily focus on subgraph-based GBAs, relying on the assumption that poisoned target nodes are explicitly connected to subgraph triggers. Our empirical results reveal that such structure-centric approaches fail to defend against emerging fea
The increasing deployment of AI, particularly Graph Neural Networks (GNNs), in critical applications necessitates robust security, making research into advanced defense mechanisms against sophisticated attacks timely.
Sophisticated graph backdoor attacks pose a significant threat to the integrity and trustworthiness of GNNs, which are foundational for many complex AI systems, impacting their adoption in high-stakes environments.
This research introduces a more comprehensive defense strategy that moves beyond structure-centric assumptions, potentially leading to more resilient GNNs against emerging and advanced backdoor attack vectors.
