A new benchmark called FraudBench has been developed to assess the adversarial robustness of machine learning models used in financial fraud and credit-risk detection. The benchmark highlights that robustness conclusions are highly dependent on the evaluation protocol, particularly concerning domain constraints and attacker capabilities. For instance, one protocol resulted in significantly more feasible-flipped examples than another under the same perturbation budget when using Lending Club Loan Data. The findings suggest that fraud robustness evaluations should jointly report predictive degradation and attack feasibility, integrating domain constraints directly into attack generation. AI
