With nothing more than a standard Web browser, cyber-criminals can find personal, private information all over the public Internet. It isn’t just legitimate services – from genealogy sites to public records and social media – that can be mined and exploited for nefarious purposes. Openly malicious criminal activities are also happening on the public Internet.

True, much of the cyber-crime underground consists of private and established communities that don’t appear in a normal search engine and are not accessible by regular users without special authorization.
