This quote from the authors hints at the investigative power of the techniques this book teaches: “Nothing I am going to describe to you is illegal, nor does it in any way involve accessing unauthorized data, [...but] involves using publicly available search engines to access publicly available information that almost certainly was not intended for public distribution.” From search strings that will reveal secret documents from South Africa (“filetype:xls site:za confidential”) to tracking down tables of Russian passwords (“filetype:xls site:ru login”), this is both an instructive and voyeuristic look at how the most powerful spy agency in the world uses Google.
