BackdoorBench: a comprehensive benchmark of backdoor attack and defense methods
Website • Paper • Leaderboard
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.
❗V2.0 Updates
✅ Correction:
- Attack : Fix the bug in Label Consistent attack method, in v1.0 version, poisoned data only add adversarial noise without square trigger, which is not consistent with the paper.
✅ Code:
- Structure : Warp attack methods and defense methods into classes and reduce replicated code.
- Dataset Processing : Update bd_dataset into bd_dataset_v2, which can handle large scale dataset more efficently.
- Poison Data Generation : Provide necessary code to generate poisoned dataset for attack methods (see ./resource folder, we have seperate readme files).
- Models : We add VGG19_bn, ConvNeXT_tiny, ViT_B_16.
✅ Methods:
- Attack :Add 4 new attack methods: Blind, BPP, LIRA, TrojanNN. (Totally 12 attack methods now).
- Defense :Add 6 new defense methods: CLP, D-BR, D-ST, EP, I-BAU, BNP. (Totally 15 defense methods now).
✅ Analysis Tools :
- Data Analysis : Add 2 new methods: UMAP, Image Quality
- Models Analysis : Add 9 new methods: Activated Image, Feature Visualization, Feature Map, Activation Distribution, Trigger Activation Change, Lipschitz Constant, Loss Landscape, Network Structure, Eigenvalues of Hessian
- Evaluation Analysis : Add 2 new methods: Confusion Matrix, Metric
🔲 Comprehensive evaluations will be coming soon...

Installation
You can run the following script to configurate 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
Quick Start
Attack
This is a example for BadNets
- 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.pngNote 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.
- 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
Defense
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.
