This weekend I was finally able to finish up a minuscule, open source, research project of mine that I’ve been working on. It’s called ProminentDork. I wrote ProminentDork to act as a very simple and generic multi-threaded web application fuzzer that uses Google dorking to obtain domain specific URLs that may be vulnerable to a variety of web vulnerabilities such as SQLi, XSS, LFI, RFI, or anything else you can scan website source for.  Although using Google dorks for web application pen-testing is nothing new, I thought it would be interesting to research Google search automation and URL aggregation, as well as learning more about how they validate a search session by using captchas in the process.  In the process, I decided to build in a simple and flexible solution for scanning the collected results for a variety of different vulnerabilities that can be detected by a string being concatenated to the end of the requested URL and then analyzing the source of the response.

Many pre-existing or current security tools that use Google dorks for auditing, are used strictly in conjunction with the Google Hacking Database or focus primarily on a specific type of vulnerability. Although, automating web auditing with Google dorks is a great way to get a quick grasp of your sites security based on popular query results, it does not, in anyway, obsolete the effectiveness of using a web crawler to generate a full site-map based on files/directories listed in the source, and then scanning those files/directories independently in conjunction with analyzing the sites structure.

ProminentDork currently supports features such as: Multiple query, error string, and appended request string support, Google Hacking Database support, proxy support, and Google captcha support. More features are sure to come as time progresses.

I wrote ProminentDork to be simple and broad enough to support many kinds of web vulnerabilities using the same method of gather->append->request->analyze. Surprisingly, that simple four step process is great for auditing your website for common web vulnerabilities. It is nice to be able to have an automated solution use Google to aggregate a list of potentially insecure/popular web pages from your specified domain and test them against a variety of different exploits that you supply. In the next release, I plan on adding in a more in depth scanning solution that will obtain all the GET and POST variables from the source and build requests off of those to return more results. I already wrote a small script in python a few months ago to do just that and I plan on implementing it into ProminentDork soon.

I wrote ProminentDork in C#, to experiment with the proclaimed ease and efficiency of implementing a thread queue through the System.Threading.ThreadPool class in .NET.
