Google Hacking for Penetration Testers 138

Posted by timothy
from the google-thyself dept.
Corey Nachreiner writes "Until recently, I considered myself a Google power-user; so much so that I often call Google my "second brain." Whenever I stumble upon a computing dilemma I can't solve, I submit an advanced query to my second brain, Google, and let it supply the answers. That's why I was So There when Johnny Long released his recent book, Google Hacking for Penetration Testers . I heard Johnny's lively, light-hearted presentation to a packed house at the BlackHat Briefings last summer in Las Vegas. It was the hit of the show, but in one hour he could only present a few of his startling findings about Google hacking. After reading Johnny's book, I've learned a ton more and realized I wasn't quite as Google-savvy as I thought. As with my real brain, I've only been using about ten percent of my Google-brain's capacity." Read on for the rest of Nachreiner's review.

tester data

According to its cover, Johnny Long's book focuses primarily on revealing the "Dark Side" of Google -- a promise it delivers in spades. But I can also heartily recommend Google Hacking to newbies who simply want to learn how to harness Google's full potential.

The first few chapters of the book walk you through Google's interfaces and features, then introduce you to Google's advanced operators and techniques you can use to refine your Google searches. Instead of submitting basic searches that leave you arduously parsing hundreds of results for your desired answer, you quickly learn to submit powerful queries that almost instantly yield the results you intend. Even as an experienced Google user, I learned a lot from Google Hacking's early chapters. For Google neophytes, this alone makes the book worth its price.

However, we all know Slashdotters really want this book in order to learn how hackers misuse Google. Well, you won't be disappointed. As soon as Long has taught you to submit advanced queries, he wastes no time in showing you the techniques l33t Google hax0rs use to exploit the search engine's power. For example, did you know you can use Google as a free proxy server? By submitting a specially-crafted, English-to-English translation query, you can capitalize on Google's translation service to anonymously submit all your Web requests. This simple hack just scratches the surface of Google's malicious potential.

Most Web surfers don't realize the sheer amount of extremely sensitive information available for the harvesting on the Internet. In that sense, Google Hacking is eye-popping. Do you want to find misconfigured Web servers that publicly list their directory contents? A quick Google search does the trick. Or, suppose you found some new exploit code that only works against a particular version of IIS 5.0. Submit a quick Google query for a helpful list of possible targets. Do you want to harvest user logins, passwords (for example, mySQL passwords in a connect.inc file), credit card numbers, social security numbers or any other potentially damaging tidbit that Web users and administrators accidentally leak onto the Internet? Google Hacking shows you how, with highly refined searches gleaned from the community contributing to the Google Hacking database (GHDB) found on Long's Web site.

While Long's book discloses these and many other potentially malicious Google searching techniques, it does so responsibly, with the goal of prevention in mind. Only the less damaging search strings are fully revealed. Long saves the juicier (read: more dangerous) hacks for your own discovery. Long even obfuscates the sensitive results of the more damaging search strings in order to protect the innocent incompetents he refers to as "googledorks." After showing you how hackers subvert Google to their malicious intent, Long dedicates a chapter to how Web administrators can configure their Web servers securely in order to prevent sensitive data from making it into a Google Hacker's clutches.

Though I've gushed about the book so far, I will quibble with its inconsistent tone. Some of its chapters target readers having different levels of technical understanding. While the book starts out in a voice easy enough for even the most novice user to understand, some of the later chapters, on topics such as document grinding, database digging, and query automation, jump drastically and use language and techniques that only programmers or Unix power-users would understand. In addition, the humor that made Johnny's live presentation so memorable shows up in his book, but in scant supply; frankly, more jokes would be welcome.

But these negatives are mere nits. Whether you're a penetration tester wanting to exploit Google, a Web administrator wanting to protect yourself from information leaks, or even a newbie wanting to harness Google's full potential, Google Hacking for Penetration Testers makes an excellent resource. If you, too, use Google as a second brain, pick up Johnny Long's book and learn how to exploit this powerful search engine to its full capacity.

    How did someone come up with this name for a profession anyways?
    • That's like when I worked in offset printing. The guys who set the film up are called "strippers."

      I'd gotten so used to the term that whenever I'd refer to "the strippers in the back, at work..." it'd catch me offguard when people would say "you've got stippers at work? where do you work again?"

      Too bad all the strippers were guys. it woulda been nice to have a female stripper there.
      • In the 3D animation industry, setting up a character for animation involves creating invisible bones and defining joint parameters that animators use to drive the animation. This step used to be called "boning" the character, but has come to be called "rigging."

    Too bad Google doesn't translate graphics, which some web pages are full of.

    • That, and they send this "x-forwarded-for" header. In my case, my IP followed by my ISP (non-anonymous) proxy's IP, followed by "unknown", all delimited using commas.

      Yeah, that's real anonymous there...

      Hmm... Google also responds with a Content-Location: header, causing Firefox to go directly to the actual page the second time.

    Correct me if I'm wrong, but Google doesn't do anything to the image references -- so that if you want to anonymously browse a website through Google, wouldn't you also have to turn image loading off on your browser? I mean, sure it'll work for text, but I didn't think this was exactly uncommon knowledge?

    Also, I don't think Google translates the hyperlinks to work within the translation-page does it? So you would have to copy out any URL's that you wanted to go to and re-enter them into your translation query.

    Can someone please tell me what's so special about this l33t "specially formed English-to-English translation" method? I mean, how much better can it be than just typing in the URL you want and choosing "Korean to English" in the drop-down?

    *** WARNING ***
    When doing a google translation proxy, remember two things:
    1) The images that you load from the target page do *not* use the proxy. So if they want to track you down, all they have to do is look for the next few image loads following the google load for the main page.
    2) en|en translations stand out in the logs, since it's not a normal translation option. You should use (for example) de|en. It'll fail on every german word and show the original word, which is english.
