Graph Injection Attack

Graph injection attacks (GIAs) target the vulnerability of graph neural networks (GNNs) by introducing malicious nodes into the graph structure, aiming to manipulate GNN predictions. Current research focuses on developing more sophisticated attack strategies, including text-level injections and reinforcement learning-based approaches to optimize attack effectiveness, while simultaneously exploring robust defense mechanisms such as certified robustness frameworks and homophily-based augmentation. Understanding and mitigating GIAs is crucial for ensuring the reliability and security of GNNs across diverse applications, from recommendation systems to social network analysis.
