AML.T0024.002 Extract AI Model

Adversaries may extract a functional copy of a private model. By repeatedly querying the victim's AI Model Inference API Access, the adversary can collect the target model's inferences into a dataset. The inferences are used as labels for training a separate model offline that will mimic the behavior and performance of the target model. Adversaries may extract the model to avoid paying per query in an artificial-intelligence-as-a-service (AIaaS) setting. Model extraction is used for AI Intellectual Property Theft.
