The ubiquity of Machine Learning (ML) models across critical infrastructure, financial services, healthcare, and intelligence sectors by late 2025 has unequivocally amplified the urgency around Adversarial Machine Learning (AML). What began as a largely academic pursuit a decade ago has matured into a significant, demonstrable threat vector that security architects and operations teams simply cannot ignore. We’re no longer debating theoretical possibilities; we’re actively facing sophisticated adversaries employing these techniques against deployed systems. The landscape has shifted from basic evasion attacks on image classifiers to more insidious data poisoning, model exfiltration, and integrity attacks against highly sensitive, decision-making AI systems. We’re seeing a convergence of traditional attack methodologies with novel ML-specific threats, demanding a holistic, defense-in-dept
