Pre-Model Representation Failures in GNN-Based Smart Contract Vulnerability Detection

A failure analysis of the representation layer underlying GNN-based smart contract vulnerability detectors finds one confirmed case of misclassification caused directly by a representation-layer failure; the prevalence of such failures in real-world contract populations remains an open empirical question.

Adversarial Robustness in Smishing Detection: A Comparative Analysis of Adversarial Fragility in Classical vs. Transformer-Based Detection Systems

It is demonstrated that clean-text performance is not a reliable predictor of adversarial robustness, and the results underscore the necessity for architecture-specific defences and frame smishing detection as an adversarial cybersecurity challenge rather than a static classification task.
