hCaptcha Challenger

🚀 Gracefully face hCaptcha challenge with Yolov5(ONNX) embedded solution.

Introduction

Does not rely on any Tampermonkey script.

Does not use any third-party anti-captcha services.

Just implement some interfaces to make AI vs AI possible.

Requirements

• Python 3.7+
• google-chrome

Usage

1. Clone the project code in the way you like.

2. Execute the following command in the project root directory.

   # hcaptcha-challenger
   pip install -r ./requirements.txt

3. Download Project Dependencies.

   The implementation includes downloading the YOLOv5 object detection model and detecting google-chrome in the current environment.

   If google-chrome is missing please follow the prompts to download the latest version of the client, if google-chrome is present you need to make sure it is up to date.

   Now you need to execute the cd command to access the src/ directory of project and execute the following command to download the project dependencies.

   # hcaptcha-challenger/src
   python main.py install

4. Start the test program.

   Check if chromedriver is compatible with google-chrome.

   # hcaptcha-challenger/src
   python main.py test

5. Start the demo program.

   If the previous test passed perfectly, now is the perfect time to run the demo!

   # hcaptcha-challenger/src
   python main.py demo

Advanced

1. You can download yolov5 onnx models of different sizes by specifying the model parameter in the install command.

   • Download yolov5s6 by default when no parameters are specified.

   • The models that can be chosen are yolov5n6，yolov5m6，yolov5s6.

   # hcaptcha-challenger/src
   python main.py install --model=yolov5n6

2. You can run different yolo models by specifying the model parameter to compare the performance difference between them.

   • Similarly, when the model parameter is not specified, the yolov5s6 model is used by default.

   • Note that you should use install to download the missing models before running the demo.

   # hcaptcha-challenger/src
   python main.py demo --model=yolov5n6

3. Comparison of programs.

   The following table shows the average solving time of the hCAPTCHA challenge for 30 rounds (one round for every 9 challenge images) of mixed categories processed by onnx models of different sizes.

   model(onnx)	avg_time(s)	size(MB)
   yolov5n6	0.71	12.4
   yolov5s6	1.422	48.2
   yolov5m6	3.05	136

   • Use of the YOLOv5n6(onnx) embedded scheme to obtain solution speeds close to the limit.

   • Use of the YOLOv5s6(onnx) embedded solution, which allows for an optimal balance between stability, power consumption, and solution efficiency.

Tour

Install Google Chrome on Ubuntu 18.04+

1. Downloading Google Chrome

   wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

2. Installing Google Chrome

   sudo apt install ./google-chrome-stable_current_amd64.deb

Install Google Chrome on CentOS 7/8

1. Start by opening your terminal and downloading the latest Google Chrome .rpm package with the following wget command :

   wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

2. Once the file is downloaded, install Google Chrome on your CentOS 7 system by typing:

   sudo yum localinstall google-chrome-stable_current_x86_64.rpm

Install Google Chrome on Windows / MacOs

Just go to Google Chrome official website to download and install.
