There is so much data available on the Internet that even government cyberspies need a little help now and then to sift through it all. Wired article Use These Secret NSA Google Search Tips to Become Your Own Spy Agency tells that the National Security Agency produced a 643-page book Untangling the Web: A Guide to Internet Research to help its spies uncover intelligence hiding on the web. That Untangling the Web: A Guide to Internet Research book is no longer NSA secret, it was just released to public by the NSA following a FOIA request.
The most interesting is the chapter titled “Google Hacking.” It has few tips like this:
- Search for confidential Excel spreadsheets the company inadvertently posted online by typing “filetype:xls site:za confidential” into Google.
- Want to find spreadsheets full of passwords in Russia? Type “filetype:xls site:ru login.”
Be careful what you publish on the web and how you do it.
