Episode 8 — Data Poisoning Attacks

This episode introduces data poisoning as a high-priority threat in AI security, where adversaries deliberately insert malicious samples into training or fine-tuning datasets. For exam readiness, learners must understand how poisoning undermines model accuracy, introduces backdoors, or biases outputs toward attacker goals. The relevance of poisoning lies in its persistence, as compromised models may behave unpredictably long after training is complete. Definitions such as targeted versus indiscriminate poisoning, as well as the concept of trigger-based backdoors, are emphasized to ensure candidates can recognize variations in exam scenarios and real-world incidents.Applied examples include adversaries corrupting crowdsourced labeling platforms, inserting poisoned records into scraped datasets, or leveraging open repositories to distribute compromised models. Defensive strategies such as dataset provenance tracking, anomaly detection in data, and robust training algorithms are explored as ways to mitigate risk. Troubleshooting considerations focus on the difficulty of identifying poisoned samples at scale and the potential economic impact of retraining models from scratch. By mastering the definitions, implications, and defenses of data poisoning, learners develop a critical skill set for both exam performance and operational AI security.
