BackdoorBench: a comprehensive benchmark of backdoor attack and defense methods

BackdoorBench is a comprehensive benchmark of backdoor learning, which studies the adversarial vulnerablity of deep learning models in the training stage. It aims to provide easy implementations of mainstream backdoor attack and defense methods.

❗Model and Data Updates

We disclose the backdoor model we used and the corresponding backdoor attack image in the link below. Each zip file contains the following things:

• bd_train_dataset: train backdoor data
• bd_test_dataset: test backdoor data
• attack_result.py: the backdoor model and the module that reads data
• cross_test_dataset: cross mode data during training(for some special backdoor attack: wanet, inputaware and so on)

If you want to use the backdoor model, you can download the zip file and unzip in your own workspace. Then you can use the function load_attack_result in the file save_load_attack.py to load the backdoor model, the poisoned train data and the poisoned test data.

Backdoor Model

✅ Since the previously shared document was inaccessible, we have now re-shared the backdoor model, and the link has been updated for your convenience. You can directly download the model using the link provided above.

❗V2.2 Updates

✅ Methods:

1. Defense :Add 9 new defense/detection methods: STRIP, BEATRIX, SCAN, SPECTRE, SS, AGPD, SentiNet, STRIP, TeCo (Totally 28 defense/detection methods now).

❗ For V2.0 please check here

⭐️ Learboard: We provide a public leaderboard of evaluating all backdoor attacks against all defense methods.

BackdoorBench will be continuously updated to track the lastest advances of backddor learning. The implementations of more backdoor methods, as well as their evaluations are on the way. You are welcome to contribute your backdoor methods to BackdoorBench.

Installation

<a href="#top">[Back to top]</a>

You can run the following script to configure the necessary environment.

git clone git@github.com:SCLBD/BackdoorBench.git
cd BackdoorBench
conda create -n backdoorbench python=3.8
conda activate backdoorbench
sh ./sh/install.sh
sh ./sh/init_folders.sh

You can also download backdoorbench by pip.

pip install -i https://test.pypi.org/simple/ backdoorbench

The pip version of backdoorbench can be viewed at this link

Quick Start

Attack

<a href="#top">[Back to top]</a>

This is a example for BadNets

1. Generate trigger

If you want to change the trigger for BadNets, you should go to the ./resource/badnet, and follow the readme there to generate new trigger pattern.

python ./resource/badnet/generate_white_square.py --image_size 32 --square_size 3 --distance_to_right 0 --distance_to_bottom 0 --output_path ./resource/badnet/trigger_image.png

Note that for data-poisoning-based attacks (BadNets, Blended, Label Consistent, Low Frequency, SSBA). Our scripts in ./attack are just for training, they do not include the data generation process.(Because they are time-comsuming, and we do not want to waste your time.) You should go to the ./resource folder to generate the trigger for training.

2. Backdoor training

python ./attack/badnet.py --yaml_path ../config/attack/prototype/cifar10.yaml --patch_mask_path ../resource/badnet/trigger_image.png  --save_folder_name badnet_0_1

After attack you will get a folder with all files saved in ./record/<folder name in record>, including attack_result.pt for attack model and backdoored data, which will be used by following defense methods. If you want to change the args, you can both specify them in command line and in corresponding YAML config file (eg. default.yaml).(They are the defaults we used if no args are specified in command line.) The detailed descriptions for each attack may be put into the add_args function in each script.

Note that for some attacks, they may need pretrained models to generate backdoored data. For your ease, we provide various data/trigger/models we generated in google drive. You can download them at here (including clean_model files, ssba,lf,lc generated triggers/samples for you convenience.)

Defense

<a href="#top">[Back to top]</a>

This is a demo script of running abl defense on cifar-10 for badnet attack. Before defense you need to run badnet attack on cifar-10 at first. Then you use the folder name as result_file.

python ./defense/abl.py --result_file badnet_0_1 --yaml_path ./config/defense/abl/cifar10.yaml --dataset cifar10

If you want to change the args, you can both specify them in command line and in corresponding YAML config file (eg. default.yaml).(They are the defaults we used if no args are specified in command line.) The detailed descriptions for each attack may be put into the add_args function in each script.
