From 1997 to 2007, Joseph V. DeMarco was an Assistant United States Attorney for the Southern District of New York, where he founded and headed the Computer Hacking and Intellectual Property (CHIPs) Program, a group of five prosecutors dedicated to investigating and prosecuting violations of federal cybercrime laws and intellectual property offenses. Under his leadership, CHIPs prosecutions grew from a trickle in 1997 to a top priority of the United States Attorney's Office, encompassing all forms of criminal activity affecting e-commerce and critical infrastructures including computer hacking and sabotage crimes; transmission of Internet worms and viruses; web-based frauds; theft of trade secrets; cyberstalking; and copyright and trademark infringement. As a recognized expert in the field, Mr. DeMarco was frequently asked to counsel prosecutors and law enforcement agents regarding novel investigative techniques and methodologies, and regularly provided advice concerning the Office's most sensitive computer-related investigations. Mr. DeMarco also served as a visiting Trial Attorney at the Department of Justice Computer Crimes and Intellectual Property Section in Washington, D.C., where he focused on technology-related policy matters such as Internet privacy, international cyber-investigations, e-commerce, identity theft, and the electronic theft of intellectual property.

In the days and weeks following September 11, 2001, he was responsible for coordinating the U.S. Attorney's Office support for the New York Secret Service Electronic Crimes Task Force's investigation into the attacks against the World Trade Center and the Pentagon.
