At the ShmooCon hacker conference in Washington, D.C., last week two security researchers showed the very sensitive information that people inadvertently make available over peer-to-peer networks.
In their presentation, “Information disclosure via P2P networks: Why stealing an identity via Gnutella is like clubbing baby seals,” pen testers Larry Pesce and Mick Douglas said they found a lot of music, porn, malcode collections and the following:
driver’s licenses, passport and tax return forms with Social Security numbers; someone’s will A retirement analysis form with savings account totals and income estimates; An IRS form with taxpayer identification number; A completed Turbo Tax form with personal information filled in.

They list best-of-breed tools for conducting the research, including Mutella and the Gnutella Protocol on their site http://pauldotcom.com/cactusproject.html.
