Some readers have asked how to report suspected or confirmed cybercrimes to the appropriate authorities. Because our readers are from all over the world, this post may not provide a global answer to all, but is should be a good starting point.

The most common cybercrimes and the suggested US federal law enforcement agencies are as follows:

• Computer intrusion (hacking, etc.), password intrusion, child pornography or exploitation, internet harassment - FBI local office, U.S. Secret Service, or the Internet Fraud Complaint Center
  
• Internet spam - FBI local office, U.S. Secret Service (Financial Crimes division),  Federal Trade Commission, Securities and Exchange Commission (financial/securities crimes), or the Internet Fraud Complaint Center
  
• Copyright, trademark, counterfeiting, trade secrets - FBI local office, Immigrations and Customs Enforcement, or the Internet Fraud Complaint Center

In the U.S. the agency dealing with cybercrime prosecution is the Department of Justice’s Computer Crime and Intellectual Property Section (CCIPS.)  Although most cybercrime in the US involves a federal agency, there are some crimes (e.g. spam, spyware, malware) that are prosecuted by a state agency - usually the state’s Attorney General. It may be worth checking your state’s Attorney General’s website for more information.
