Have you guys heard about Google Hacking? Does this sound exciting to you? So let’s just deep dive into Google Dorks. Now, Google Dork, which is also known as Google Dorking or Google Hacking is a very important resource for security researchers. For most people, Google is just a search engine that helps to find videos, articles, games, images, news, and many more things. But for an infosec guy, Google is a useful hacking tool.

Google has tremendous web-crawling capabilities but you can’t hack sites using google directly. It indexes almost anything within your website, which includes sensitive information of that website including the information about the web technologies, username, passwords, and general vulnerabilities without the knowledge of the owner of the website.

Google Hacking sounds interesting and but it’s not actually hacking Google and you can’t do that. Dorks are termed as Google Hacking and this information is widely available on the internet and it is legal and encouraged to use by Google itself. People with the wrong intentions could use this to hark your online presence.

Some website owners expose sensitive information of their website on their own but that doesn’t mean it’s legal to take advantage or to exploit that information. This will come under cybercrime and you will be traced with the help of your IP address even if you are using VPN. Nothing is anonymous in this digital world.
