Millennium Group has had to report crime on several occasions.  It is wise to know what you should do if and when cybercrime hits you.  Here is the overview from the Justice Department’s Cybercrime website:

The primary federal law enforcement agencies that investigate domestic crime on the Internet include: the Federal Bureau of Investigation (FBI), the United States Secret Service, the United States Immigration and Customs Enforcement (ICE) , the United States Postal Inspection Service, and the Bureau of Alcohol, Tobacco and Firearms (ATF) . Each of these agencies has offices conveniently located in every state to which crimes may be reported. Contact information regarding these local offices may be found in local telephone directories. In general, federal crime may be reported to the local office of an appropriate law enforcement agency by a telephone call and by requesting the “Duty Complaint Agent.”

Each law enforcement agency also has a headquarters (HQ) in Washington, D.C., which has agents who specialize in particular areas. For example, the FBI and the U.S. Secret Service both have headquarters-based
specialists in computer intrusion (i.e., computer hacker) cases. To determine some of the federal investigative law enforcement agencies that may be appropriate for reporting certain kinds of
