GitHub for Bug Bounty Hunters

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.

Mass Cloning

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

Extract the index.xml
unzip Filename.iba index.xml

Edit your index.xml file as you see fit (like changing the GUID: http://www.reactuate.com/2013/03/21/ibooks-guid-problem-when-duplicating-ibooks-author-documents/)

Remove the original index.xml entry from the .iba file
zip -d Filename.iba index.xml

Re-add the modified one to the end, with the proper compression (assuming modified index.xml in same dir as Filename.iba)
zip Filename.iba index.xml
