National Security Division

The Office’s National Security Division complements the Criminal Division, but with has its own specialized mandates. This division combats evolving national security and cyber threats facing our region and our nation, the Department of Justice’s highest priority of the Department of Justice. The lawyers and staff in this division handle some of the Office’s most complex cases in the Office, and work closely with other components within the Department of Justice and with other government agencies to meet this challenge.

Lawyers in the National Security Division perform all the functions of federal prosecutors in the Criminal Division, but with a mandate that includes prevention and disruption as well as prosecution. Assistant United States Attorneys (AUSAs) work with federal law enforcement partners to investigate, disrupt, and prosecute federal criminal violations involving international and domestic terrorism, espionage, foreign malign influence, and transnational repression, and violations of United States export control laws and economic sanctions. 

AUSAs also investigate and prosecute nation-state cybercrime, providers of cybercriminal infrastructure, wide-scale organized crime involving virtual assets, economic espionage, and cyberstalking. National Security Division AUSAs work with U.S. and international partners to identify and disrupt significant networks of cybercriminals and the digital infrastructure that they use to perpetuate and enable criminal activity, detection and disruption of state-sponsored cyber activity, prosecution of cyberstalkers, and protection of significant intellectual property.
