Blacklight: Scalable Defense for Neural Networks against Query-Based Black-Box Attacks

ABOUT

This repository contains code implementation of the paper "Blacklight: Scalable Defense for Neural Networks against Query-Based Black-Box Attacks", at USENIX Security 2022. Blacklight is a novel defense that detects query-based black-box attacks using an efficient content-similarity engine developed by researchers at SANDLab, University of Chicago.

DEPENDENCIES

Our code is implemented and tested on Python 3.6.9 and the following packages are required.

• config==0.5.1
• numpy==1.19.5
• torchvision==0.11.2

And the Jupyter core packages we use is:

IPython          : 7.16.3
ipykernel        : 5.5.6
ipywidgets       : 7.7.0
jupyter_client   : 7.1.2
jupyter_core     : 4.9.2
nbclient         : 0.5.9
nbconvert        : 6.0.7
nbformat         : 5.1.3
notebook         : 6.4.10
qtconsole        : 5.2.2
traitlets        : 4.3.3

How to run detection:

Please look into the example in example.ipynb as reference. Please normalize the queries into $[0,1]$ and make sure all the queries, including both attack and benign queries, are in the same format.
