ReCaptaBreaker

Auto Solve Google's Recaptcha Image Challenge with near human performance!

This is one of the first library that breaks google recaptcha image challenge using autmoated system right in your device, with near human accuracy!

Installing

You can use pypi distribution:

pip install recaptchabreaker

or install locally from source:

git clone https://github.com/Hackear2041/ReCaptchaBreaker.git
python setup.py install

Models will be downloaded on first use.

Usage

1. You can use the solver in selenium based drivers

from recaptchabreaker import ReCaptchaBreaker
breaker = RecaptchBreaker() 

# Load the page, where recaptcha needs to be solved.
# The method will automatically find the captcha and solve it.
breaker.solve_captcha(driver)

2. You can directly classify on images as well

from recaptchabreaker import ReCaptchaBreaker
breaker = RecaptchBreaker() 

# Load the list of images
image_list : List[PIL.Image] = ...

for pred in breaker.solve_images():
    print(pred) # Prints dictionary of label:score

Hardware Requirements

Any device with python support and atleast 1GB RAM and 500MB free space should be supported. Expected classification time is ~1sec for 4*4 recaptcha Grid, and is dependent on number of CPU cores available. Faster Models Coming Soon!

How it Works?

I train Clip model for classification and Diffusion models for synthetic dataset generation. Further, using an iterative procedure, new annotated data points are collected by applying a week classifier to a real recaptcha system. The classifier model is further trained on the collected and augmented dataset resulting in a better classifier. The method is easily extendible to other forms of image captcha tasks such as hCaptcha.
