This paper applies federated learning and XGBoost, with SHAP-based explanations, to ransomware detection across four non-IID clients. The reported gains (99.59% accuracy, 75% lower energy and communication overhead) come from the authors' own benchmarks against FedAvg, FedProx, and SCAFFOLD, so they need independent replication. Readers should watch whether the efficiency claims hold under realistic client counts and whether the detector stays robust against adaptive attackers.
AdaFedXplain: Adaptive Federated Learning with Explainable AI for Ransomware Detection
arXiv:2610.25318v1 Announce Type: cross Abstract: Attacks using ransomware have developed into complex multiphase campaigns that target vital infrastructure, resulting in annual damages of billions of dollars. Conventional detection techniques are ineffective against zero-day variations, and privacy issues are raised by centralized machine learning algorithms. Federated learning allows for cooperative model training without data sharing, however current FL approaches suffer from explainability issues, high communication cost, and non-IID data heterogeneity. In this study, we present AdaFedXplain, an explainable AI-based adaptive federated learning system for ransomware detection. Our approach includes progressive XGBoost complexity to avoid overfitting, a decaying learning rate schedule for stable convergence, and dynamic client grading based on ransomware prevalence and data sufficiency. Using 62,485 real-world ransomware samples from four OS-based non-IID clients, we compare AdaFedXplain against FedAvg, FedProx, and SCAFFOLD. According to experimental data, AdaFedXplain outperforms all baselines with 99.59% detection accuracy and 99.64% F1-score while cutting energy usage by 75%, latency by 65%, and communication overhead by 75%. The ablation investigation demonstrates that every element enhances performance. Security analysts can use SHAP explainability to identify important PE header characteristics that influence detection decisions. Our system provides a collaborative ransomware detection solution that is efficient and interpretable, while reducing privacy risks through federated learnings data-local training paradigm.
