Last year's Lord of the Bing presentation stabbed Google Hacking in the heart with a syringe full of adrenaline and injected life back into a dying art form. New attack tools and modern defensive techniques redefined the way people thought about Google Hacking. Among these were the first ever Bing Hacking tool and the Google/Bing Hacking Alert RSS feeds, which have grown to become the world's single largest repository of live vulnerabilities on the web. And it was only the beginning…

This year, we once again tear down the basic assumptions about what Google/Bing Hacking is and the extent to which it can be exploited to target organizations and even governments. In our secret underground laboratory, we've been busy creating an entirely new arsenal of Diggity Hacking tools that we'll be unveiling for the first time and releasing for free at Black Hat USA 2011. Just a few highlights of new tools to be unveiled are:

BaiduDiggity:first ever Baidu hacking tool, which targets vulnerabilities disclosed by China's dominant search engine. DEMO: Live targeting of vulnerabilities in Chinese government websites exposed via Baidu.
DroidDiggity:fully functional GoogleDiggity and BingDiggity application for Android phones.
GoogleCodeSearchDiggity:identifying vulnerabilities in open source code projects hosted by Google Code, MS CodePlex, SourceForge, and more. The tool comes with over 40 default searches that identify SQL injection, cross-site scripting (XSS), insecure remote and local file includes, hard-coded passwords, and much more.
FlashDiggity:automated Google searching/downloading/decompiling/analysis of SWF files to identify Flash vulnerabilities and info disclosures.
SHODAN Hacking Alerts:new live vulnerability RSS feeds based on results from the popular SHODAN hacking search engine.
MalwareDiggity and MalwareDiggity Alerts:leveraging Bing API and the Google SafeBrowsing API together to provide an answer to a simple question, "Am I being used as a platform to distribute malware to people who visit my website?"
AlertDiggity:Windows systray application that filters the results of the various Google/Bing/Shodan Hacking Alerts RSS feeds and notifies the user if any new alerts match a domain belong to them.
DiggityDLP:Data loss prevention tool that leverages Google/Bing to identify exposures of sensitive info (e.g. SSNs, credit card numbers, etc.) via common document formats such as .doc, .xls, and .pdf. Also utilizes Google APIs for searching across Google Docs/Spreadsheets for data leaks.
That is just a taste of the new tools that will be explored in this DEMO rich presentation. So come ready to engage us as we re-define Google Hacking once again.
