During a Senate hearing in September, the FBI director described what the agency sees as the top four threats facing the United States.

FBI Director Christopher Wray told the Senate Committee on Homeland Security and Governmental Affairs that foreign terrorist organizations, homegrown violent extremists, cyberattacks, and malign foreign influence present the biggest threats to the United States.

In addition to the four threats the FBI has identified, the wider intelligence community and the Department of Defense have also highlighted that supply-chain vulnerabilities pose an additional threat to U.S. national security and private industry.

The threats come from both state and non-state actors, with China and Russia behind some of the challenges.
