I know there have been a few mentions on the FBI, but I wanted to throw some resources out there for those that may need more info.

For those in the U.S. (or potentially if your transaction / dealings were international and involved the U.S. or a U.S. citizen), here are some useful links from the Federal Bureau of Investigation's (FBI) website at fbi.gov..

• FBI's page on White Collar Crime
• FBI's page on Cyber Crime
• Law Enforcement Cyber Incident Reporting
• Internet Crime Complaint Center
  "The mission of the Internet Crime Complaint Center (IC3) is to provide the public with a reliable and convenient reporting mechanism to submit information to the FBI concerning suspected Internet-facilitated fraud schemes and to develop effective alliances with law enforcement and industry partners. Information is analyzed and disseminated for investigative and intelligence purposes to law enforcement and for public awareness."
