The Current State of Adversarial Machine Learning in Late 2025 It's April 2026, and the landscape of machine learning (ML) security has evolved considerably. We're past the theoretical discussions; adversarial machine learning (AML) is no longer an academic curiosity. Threat actors, particularly sophisticated state-sponsored groups and well-resourced criminal enterprises, have moved beyond traditional network and application layer attacks to directly target the ML models themselves. We’re seeing a significant uptick in real-world exploitation attempts against systems leveraging AI-driven decision making, from fraud detection and credit scoring to autonomous vehicle guidance and critical infrastructure monitoring. The shift is palpable: adversaries are treating models as just another attack surface, albeit a complex and often opaque one. The days of simply securing the data pipeline and t
