We all know the famous quote “Think out of the box”. Technical knowledge is important but creativity is also. In bug bounty, to get nice rewards, sometimes you don’t need to be a crazy coder or great network engineer, you simply need to try what other didn’t.

I found an interesting project, on GitHub itself, to parse the search engine results: vcsmap from Melvinsh. Unfortunately the scrapper seems to have trouble with search that required authentication. Since I don’t understand Ruby, I wrote my own tool with PHP.
The code is available on my GitHub repository and for sure, you can tweak it to fit your needs. Usage is:
Usage: php github-search.php [OPTIONS] Options: -c set cookie session -e file extension filter -f looking for file -h print this help -o provide organization name -r maximum number of results, default 50 -s search string Examples: php github-search.php -o myorganization -s db_password php github-search.php -o myorganization -f wp-config.php -s db_password php github-search.php -c "user_session=B0KqycP8LlYORc-s3WFZoH71TG" -f wp-config -e php -r 1000
An organization name must be provided when you are not authenticated on GitHub, that why the cookie option exists, of course you should use your own cookie value. And here is the output:
