Study Notes
Model Extraction Attacks
- Model extraction attacks are becoming more prominent due to the popularity of cloud computing and machine learning as a service (MLaaS).
- These attacks involve building a machine that produces the same results as the target model, allowing the attacker to bypass monetization and use the duplicate model offline.
- There are three main categories of model extraction attacks: equation-solving, path finding, and membership queries.
Equation-Solving Model Extraction Attacks
- This type of attack involves tailoring input data to build a linear system of variables and solving it for unknown weights and bias.
- Simple models like logistic regression can be easily recreated with 100% accuracy using this method.
- Even complex models like neural networks can be recreated, although it may be more difficult.
Path Finding Attacks
- This method assumes that each leaf in the decision tree has a unique distribution, allowing the attacker to rebuild the tree by querying the model and tracking which leaf the data falls into.
- By changing the input data one feature at a time, the attacker can figure out the different branches of the tree.
Membership Queries Attacks
- This type of attack involves training a local model, querying the target model, and retraining the local model to adapt to the target model's responses.
- The attacker can assume a model, train it, and then query the points where the local confidence is low.
Adversarial Examples
- Adversarial examples are inputs tailored to cause machine learning models to make mistakes.
- These examples can be crafted using model extraction attacks and the property of transferability.
- Transferability means that an adversarial example for a model in a specific domain will likely be adversarial to any other model trained in that domain.
- Adversarial examples can be used to cause misclassification in machine learning models.
Crafting Adversarial Examples
- Adversarial examples can be crafted by adding a perturbation to the input data based on the gradient and changing the image to a misclassified image with the lowest cost.
- This process can be automated using model extraction attacks and transferability.
