Counterterrorism Indicators

Individuals involved in terrorism or subversion sometimes engage in behaviors that are observable by others and give clues to what might be going on. Alert supervisors and coworkers who recognize and report these clues play a significant role in helping to protect our country against terrorist attacks and other subversive activities.

The information below alerts you to potential indicators of terrorist preparations or subversive activities that you could conceivably observe or learn about. These indicators are applicable both in the United States and abroad. For readers stationed abroad, these indicators apply to local national employees associated with U.S. installations as well as to Americans.


Security Is Your Job

Some of these behaviors may have innocent explanations, but it is not up to you to make that judgment. If you observe any of these indicators, you should report this information to your organization's security officer, the nearest FBI office, local law enforcement, or call one of the Hotline Numbers set up for the reporting of such information.

The appropriate office will evaluate the information in the context of all other information known about the individual and about potential terrorist activity in your area. Depending upon the circumstances, action may range from nothing to conducting a discrete investigation. You may request that your identity be protected.

Reportable Indicators

Potential Indicators of Terrorist Preparations

The following are potential indicators that an individual may be planning, may be aware of others who are planning, or may be motivated to assist in conducting a terrorist attack.

  • Talk knowingly about a future terrorist event, as though the person has inside information about what is going to happen.
     
  • Statement of intent to commit or threatening to commit a terrorist act, whether serious or supposedly as a “joke,” and regardless of whether or not you think the person intends to carry out the action. (All threats must be taken seriously.)
