GitHub repositories can disclose all sorts of potentially valuable information for bug bounty hunters. The targets do not always have to be open source for there to be issues. Organization members and their open source projects can sometimes accidentally expose information that could be used against the target company. in this article I will give you a brief overview that should help you get started targeting GitHub repositories for vulnerabilities and for general recon.

You can just do your research on github.com, but I would suggest cloning all the target's repositories so that you can run your tests locally. I would highly recommend @mazen160's GitHubCloner. Just run the script and you should be good to go.

$ python githubcloner.py --org organization -o /tmp/output

• Navigate to page from where you want to extract links
• Open your browser's console and paste the following ;

    document.querySelectorAll('script[src]').forEach((i)=>document.write(i.src+'<br/>'))

• Copy all links and write it into a file (ex: jslinks.txt)
• Open your terminal and cd to directory where you've downloaded LinkFinder
• Run the following command

 while IFS= read link; do python linkfinder.py -i "$link" -o cli; done < jslinks.txt | tee -a output.html
