Episode 12 — Model Theft & Extraction

This episode addresses model theft and extraction, highlighting how adversaries can replicate or steal valuable AI models. Model theft occurs when proprietary weights or architectures are exfiltrated, while model extraction involves querying an exposed API repeatedly to reconstruct decision boundaries or functionality. For exam purposes, learners must be able to distinguish between these two concepts and describe the potential impacts, which include intellectual property loss, competitive disadvantage, and undermining of security guarantees. These risks make model theft an enterprise-level concern, requiring both technical and governance-oriented defenses.The applied discussion examines scenarios such as adversaries using adaptive querying strategies against APIs, attackers stealing pre-trained weights from unsecured repositories, or insiders misusing privileged access to exfiltrate models. Defensive measures include authentication and rate limiting, anomaly detection in API traffic, and cryptographic watermarking or fingerprinting to prove ownership of models. The episode also emphasizes legal and compliance aspects, such as licensing terms and intellectual property protection, which often appear in exam questions. Troubleshooting considerations highlight the difficulty of distinguishing legitimate heavy usage from extraction attempts, underscoring the need for layered monitoring strategies. By mastering this topic, learners gain readiness to explain both attacker tactics and organizational safeguards in certification settings.
