A Google Dork, also known as Google Dorking or Google hacking, is a valuable resource for security researchers. For the average person, Google is just a search engine used to find text, images, videos, and news. However, in the infosec world, Google is a useful hacking tool.
How would anyone use
Since Google has incredible web-crawling skills, it can index practically anything on your website, including sensitive data, even though you can’t directly hack websites using it. This implies that without even realizing it, you could be disclosing too much information about your web technology, usernames, passwords, and general weaknesses.
In other words: Google “Dorking” is the practice of using Google to find vulnerable web applications and servers by using native Google search engine capabilities.
Unless you block specific resources from your website using a robots.txt file, Google indexes all the information that is present on any website. Logically, after some time any person in the world can access that information if they know what to search for. You can also access the Google Hacking Database (GHDB) which is the full Google dork list containing all Google dorking commands.
Important note: while this information is publicly available on the Internet, and it is provided and encouraged to be used by Google on a legal basis, people with the wrong intentions could use this information to harm your online presence.
Be warned that when you do this type of query, Google also knows who you are. It is encouraged to utilize it exclusively for good purposes, whether for your own research or when looking for strategies to protect your website from this kind of vulnerability, for this reason and many others.
While some webmasters expose sensitive information on their own, this doesn’t mean it’s legal to take advantage of or exploit that information. If you do so you’ll be marked as a cybercriminal. It’s pretty easy to track your browsing IP, even if you’re using a VPN service. It’s not as anonymous as you think.
