What is Model Extraction Attack in Cybersecurity?
An attack where an adversary recreates a proprietary machine learning model by systematically querying its API and using the responses to train a functionally equivalent copy. The stolen model can then be used to find adversarial examples, bypass the original model's defenses, or simply avoid paying for API access. Also called model stealing or model cloning.
Why Model Extraction Attack Matters for Your Cybersecurity Career
Companies selling ML-based security products face intellectual property theft through extraction attacks. Security engineers must implement rate limiting, query monitoring, and output perturbation to protect model APIs. Understanding this attack helps threat modelers assess the risk of exposing ML models through public-facing interfaces.
