What you don't know won't hurt you is a saying very wrong in the confidential Chicago terrorist threat assessment which was leaked over P2P. In 2002, a study performed by top consulting firm Booz Allen Hamilton Inc., commissioned by the Federal Transit Administration (FTA), considered 35 threat assessments of the nation's bus and rail systems.
Larry Yellen, a Fox News reporter, acquired the confidential terrorist threat assessment on Chicago over a peer-to-peer (P2P) program, LimeWire, a public file-sharing network.
With Al-Qaida urging the U.S. to embrace Islam, a traditional notice before an imminent military strike, the information is revealing, and alarming in how available critical knowledge is readily disseminated on the Internet.
Popular P2P clients such as Kazaa, LimeWire, BearShare, Morpheus, and FastTrack are designed to let users quickly download and share files. If the access these P2P clients have on a system is not secure, it is easy to expose and share personal data with users on a file-sharing network.
In July, the House Committee on Oversight and Government Reform heard testimony from several witnesses about how everything from classified military documents to corporate data can be found on P2P networks. The leaked documents on P2P networks included the Pentagon's entire secret backbone network infrastructure diagram; contractor data on radio frequency manipulation to defeat improvised explosive devices in Iraq; and physical terrorism threat assessments for three major U.S cities.
