Gradient And Update Leakage (GAUL) In Federated Learning

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Gradient and Update Leakage attacks intercept and analyze gradient updates or model changes in distributed or federated learning environments to reconstruct the underlying model. In federated learning or other collaborative training setups,…

An Introduction To AI Model Extraction

Posted on June 7, 2025June 7, 2025 by Brian Colwell

AI model extraction refers to an attack method where an adversary attempts to replicate the functionality of a machine learning model by systematically querying it and using its outputs to train a…

What Are The Types Of AI Model Extraction Attacks?

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Model Extraction Attacks aim at stealing model architecture, training hyperparameters, learned parameters, or model behavior, and are effective across a broad threat landscape that features many practical attack vectors. Today, let’s discuss the most…

What Is Alignment-Aware Extraction?

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Alignment-Aware Extraction goes beyond conventional extraction methods by strategically capturing both the functional capabilities and ethical guardrails implemented in modern AI systems. By specifically accounting for alignment procedures like Reinforcement Learning from Human Feedback…

Cloud Infrastructure Creates Vulnerabilities For AI Model Extraction

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Cloud infrastructure vulnerabilities comprise security weaknesses in the cloud platforms and services that host machine learning models, which can be exploited to gain unauthorized access to model artifacts. Machine learning models deployed…

Model Deployment Creates Vulnerabilities For AI Model Extraction

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Model Deployment Vulnerabilities are weaknesses in how models are deployed in production environments that can be exploited to extract model information or parameters. Production deployments often expose vulnerabilities, such as insufficient access…

What Are Equation-Solving Attacks?

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Equation-Solving Attacks represent a specialized and powerful subset of extraction techniques that, while limited in scope to certain model types, achieves perfect extraction scores (100% replication) with only black-box access to the…

What Is Model Leeching?

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Model Leeching is a Model Extraction attack in which an adversary siphons task-specific knowledge from a target large language model (LLM) by interacting with it solely through its public API (API Querying) – the…

Introduction To API Querying In AI Model Extraction

Posted on June 7, 2025June 7, 2025 by Brian Colwell

API Querying is a systematic approach where attackers send repeated inputs to a model hosted as a service and collect the corresponding outputs to reconstruct the model’s functionality. This is the most…

What Are Path-Finding Attacks?

Posted on June 7, 2025June 7, 2025 by Brian Colwell

Path-Finding is a specialized model extraction attack that targets tree-based machine learning models, such as decision trees and random forests, exploiting confidence values and using the rich information provided by APIs on…
