(U//FOUO) National Counterterrorism Center Mobilizing Homegrown Violent Extremists (HVEs) Behavioral Indicators

A US Government interagency study of homegrown violent extremists (HVEs) revealed four major mobilizing patterns shared by a majority of HVE cases between 2008 and 2010, providing officials with an emerging picture of distinct behaviors often associated with an individual mobilizing for violence. These four patterns—links to known extremists, ideological commitment to extremism, international travel, and pursuit of weapons and associated training—repeatedly appeared in the case studies, reinforcing initial assessments of potential trends. Awareness of the patterns can help combat the recent rise in these cases while providing a data-driven tool for assessing potential changes in the HVE threat to the Homeland.

The attempted bombing in Times Square on 1 May 2010 highlights the need to identify Homegrown Violent Extremists before they carry out a terrorist act. The ability of the bomber to operate under the radar demonstrates the difficulties associated with identifying terrorist activity and reinforces the need for law enforcement, at all levels, to be vigilant and identify individuals who are planning violence or other illegal activities in support of terrorism.

NCTC Lone-Actor Terrorists with Biological Expertise: A Potential Threat with Limited Indicators

Elements of the U. S. government hosted an interdisciplinary, unclassified workshop to better understand the potential threat from independently acting terrorists with biological expertise. Such lone-actor terrorists have the potential to carry out high-impact biological attacks while generating few signatures, making detection or disruption of their efforts challenging. The one-day workshop explored the possible motivations, intents, and objectives of lone-actor terrorists who might consider conducting biological attacks; examined scientific infrastructure vulnerabilities that these individuals could exploit; and identified strategies to mitigate this potential threat.
