Terrorism

Protecting the United States from terrorist attacks is the FBI’s number one priority. The Bureau works closely with its partners to neutralize terrorist cells and operatives here in the United States, to help dismantle extremist networks worldwide, and to cut off financing and other forms of support provided to foreign terrorist organizations.

Terrorism Definitions

International terrorism: Violent, criminal acts committed by individuals and/or groups who are inspired by, or associated with, designated foreign terrorist organizations or nations (state-sponsored).

Domestic terrorism: Violent, criminal acts committed by individuals and/or groups to further ideological goals stemming from domestic influences, such as those of a political, religious, social, racial, or environmental nature.

The Current Threat

Domestic terrorism: Violent, criminal acts committed by individuals and/or groups to further ideological goals stemming from domestic influences, such as those of a political, religious, social, racial, or environmental nature.

The internet and social media: International and domestic violent extremists have developed an extensive presence on the Internet through messaging platforms and online images, videos, and publications. These facilitate the groups’ ability to radicalize and recruit individuals who are receptive to extremist messaging.

Social media has also allowed both international and domestic terrorists to gain unprecedented, virtual access to people living in the United States in an effort to enable homeland attacks. The Islamic State of Iraq and ash-Sham (ISIS), in particular, encourages sympathizers to carry out simple attacks wherever they are located—or to travel to ISIS-held territory in Iraq and Syria and join its ranks as foreign fighters. This message has resonated with supporters in the United States and abroad.



How Citizens Can Protect Themselves and Report Suspicious Activity

It is important for people to protect themselves both online and in-person, and to report any suspicious activity they encounter. The simplest ways to accomplish this are to:

  • Remain aware of your surroundings.
  • Refrain from oversharing personal information.
  • Say something if you see something. The insular nature of today’s violent extremists makes them difficult for law enforcement to identify and disrupt before an attack. Many times, a person’s family or friends may be the first to notice a concerning change in behavior that may indicate a person is mobilizing to violence.

Additional information regarding how to report suspicious activity and protect the community is available via the resources below.

  • Nationwide SAR Initiative (NSI): The Nationwide Suspicious Activity Reporting (SAR) Initiative is a joint collaborative effort by the U.S. Department of Homeland Security, the FBI, and law enforcement partners.
  • Community Preparedness Tools: The Department of Homeland Security offers security resources for businesses and communities.
  • The Contact Us section of fbi.gov provides detailed contact information for the FBI’s local and international offices. You can also submit a tip online.
  • The U.S. Violent Extremist Mobilization Indicators booklet lists behaviors that could mean someone is planning ideologically motivated violence.



Partnerships

Combating terrorism effectively requires the continuous exchange of information and close, daily coordination among U.S. law enforcement, members of the U.S. Intelligence Community, first responders, international law enforcement agencies, and others. To help ensure the two-way flow of information and intelligence, the FBI participates in numerous national and local joint terrorism task forces and interagency initiatives such as the National Counterterrorism Center and in fusion centers.

The FBI and our partners disrupted a Chinese botnet and freed thousands of impacted devices from its clutches, Director Christopher Wray announced September 18.

Terrorism Investigations

The FBI is bound by guidelines issued by the attorney general that establish a consistent policy on when an investigation may be initiated. Through these guidelines, the FBI obtains authorization to collect information. The facts are analyzed and then used to prevent terrorist activity and, whenever possible, to aid in the arrest and prosecution of persons or groups who have violated the law.



The approach taken by the FBI in counterterrorism investigations is based on the need both to prevent incidents where possible and to react effectively after incidents occur. Our investigations focus on the unlawful activity of the group, not the ideological orientation of its members. When conducting investigations, the FBI collects information that not only serves as the basis for prosecution but also builds an intelligence base to help prevent terrorist acts.

Asset Forfeiture

Asset forfeiture is a powerful tool used by law enforcement agencies, including the FBI, against criminals and criminal organizations to deprive them of their property used illegally and their ill-gotten gains through seizure of these assets. It is also used to compensate victims of crime. Learn more about the FBI’s asset forfeiture program and to see forfeiture in action.
