• Membership Inference Attacks: Detecting What Was in an AI Model's Training Data

  Membership inference attacks let adversaries determine—with significant accuracy—whether a specific data record was used to train a model. This post covers the attack mechanisms, why models leak this information, real-world threat scenarios, and how differential privacy and machine unlearning address (and fail to fully close) the gap.

• Machine Unlearning Security: When Forgetting Training Data Creates New Vulnerabilities

  Regulators are demanding AI systems forget specific training data. Attackers are figuring out how to weaponize that forgetting — through verification gaps, induced forgetting abuse, and unlearning as a path to alignment degradation.
