The Confidence Trap: Calibration Attacks for Graph Neural Networks

Researchers have developed a Unified Graph Calibration Attack (UGCA) framework that exploits vulnerabilities in Graph Neural Networks' confidence calibration through adversarial structural perturbations. The study reveals that GNNs with higher accuracy or trained on complex datasets are more susceptible to calibration attacks, which increase prediction uncertainty while maintaining classification accuracy.
