Welcome to another part of the Grey Hat Area!
Today I will be giving you many Google dork syntax's for your hacking pleasure
The concept of "Google Hacking" dates back to 2002, when Johnny Long began to collect interesting Google search queries that uncovered vulnerable systems and/or sensitive information disclosures - labeling them googleDorks. Some people call it googlehacking.
I have multiple lists of dorks you can refer to located at the following links below.
It goes without saying but I'll say it anyways, lets not use these in a malicious manner, ok? If you find some sensitive information please inform the company like an ethical researcher would :D (this information was complied from multiple sources online and may contain duplicates)
