Identifying and profiling threat actors are high priority tasks for a number of governmental organizations. These threat actors may operate actively, using the Internet to promote propaganda, recruit new members, or exert command and control over their networks. Alternatively, threat actors may operate passively, demonstrating operational security awareness online while using their Internet presence to gather information they need to pose an offline physical threat. This paper presents a flexible new prototype system that allows analysts to automatically detect, monitor and characterize threat actors and their networks using publicly available information. The proposed prototype system fills a need in the intelligence community for a capability to automate manual construction and analysis of online threat networks. Leveraging graph sampling approaches, we perform targeted data collection of extremist social media accounts and their networks. We design and incorporate new algorithms for role classification and radicalization detection using insights from social science literature of extremism. Additionally, we develop and implement analytics to facilitate monitoring the dynamic social networks over time. The prototype also incorporates several novel machine learning algorithms for threat actor discovery and characterization, such as classification of user posts into discourse categories, user post summaries and gender prediction.

Drawing from ethnographic and documentary data, this article examines the character of the social spaces that white power movement (WPM) activists create on the Internet and the linkages to their real world activism. Specifically, we explain how white power activists use cyberspace as a free space to create and sustain movement culture and coordinate collective action. The WPM’s cyberpresence intersects with and enhances their real world activities by offering multiple opportunities for access and coordination. Virtual contact with the WPM community offers members social support, companionship, and a sense of belonging to a community of Aryan believers. We argue that real and virtual spaces are not completely separate spheres but rather closely inter-twined. Consequently, virtual spaces provide an opportunity to parallel and extend the type of interaction present in real world free spaces that are so critical to nurturing and sustaining white power movement culture. Cyberspace is being used to connect all sorts of people, yet the character of those connections is unclear. Some observers argue that cyberspace is a new place of assembly where real world social communities can be established, sustained, or renewed as virtual communities. In The Virtual Community (1993), Howard Rheingold argues the Intemet introduced a new form of community that can help bring people together on-line around shared values and interests, and create ties of support that extend their real world collective interaction. Sherry Turkle (1995:267), a pioneer in studies of identity and interaction on the Intemet, claims that the virtual realm offers “a dramatic Please direct correspondence to Pete Simi,.

On October 7, 2023, during the Jewish Sabbath and festival of Simchat Torah, Hamas shocked the world by invading Israel from Gaza across multiple entry points. The results were devastating: the single largest one-day total of murdered Jews since the Nazi Holocaust. Hamas targeted civilian families, assaulted and kidnapped hundreds of other civilians who were taken hostage in Gaza. Evidence suggests that Hamas was preparing for a ‘second phase’ of assaults, targeting the people of Israel. In response to this unprecedented massacre of 1,200 Israelis and the kidnapping of others, Israeli forces invaded Gaza with the stated goal of destroying Hamas.

In the online sphere, the vicious attacks set off a wave of posts, images, memes, cyber terror attacks, and videos on social media, but also on the dark web and adjacent sites. The Simon Wiesenthal Center’s (SWC) Digital Terrorism and Hate Project monitors the social media activities of over 7,000 groups, individuals, and online channels, many who support Hamas and other terrorist groups. This report will explore the explosion of cyberterrorist activity against Jewish and Israeli targets in the wake of October 7th and expose some of the key groups and actors that have caused significant disruption and threats to personal safety.

The Internet’s unprecedented global reach and scope combined with the difficulty in monitoring and tracing communications make the Internet a prime tool for extremists and terrorists. The Simon Wiesenthal Center has been monitoring these developments for nearly two decades through our Digital Terrorism and Hate Project. Our findings reveal that as the Internet has grown, the escalation of extremist sites has kept pace in number and in technological sophistication.
