This module introduces the foundational concepts of data poisoning in AI and machine learning. You will explore how adversaries manipulate training datasets to inject backdoors, introduce systemic bias, or degrade overall model accuracy. Through real-world case studies and threat modeling, you will learn to identify vulnerable data pipelines and understand the catastrophic impact of compromised training data on both classical ML and modern LLMs.
