Researchers have developed a new method called Cross-Paradigm Graph Backdoor Attacks with Promptable Subgraph Triggers (CP-GBA) to address vulnerabilities in Graph Neural Networks (GNNs). Existing attacks are often limited to specific GNN learning paradigms, hindering their effectiveness across different frameworks. CP-GBA utilizes Graph Prompt Learning to create transferable subgraph triggers that are class-aware, feature-rich, and structurally sound, demonstrating state-of-the-art attack success rates in experiments.
