Expert: 'Nihilistic violence' online is increasingly targeting youth, ISD analyst tells state task force

Catherine Canuli, director of threat analysis and prevention at the Institute for Strategic Dialogue (ISD), told the Domestic Extremism and Mass Violence Task Force that a growing set of online communities is driving youth‑targeted violence and exploitation.

"Last year, we submitted 41 briefs to law enforcement … 34 of those briefs sent to law enforcement were directly tied to nihilistic violence," Canuli said, arguing that the statistic shows how pervasive the problem has become and how often it involves youth. She defined "nihilistic violence" as violent acts and illegal activity driven by a misanthropic worldview rather than a political ideology: "Their goal is commit violence for violence's sake," she said.

Canuli described three tiers of online platforms in which these communities operate — mainstream platforms with broader moderation (for example, Instagram, TikTok), alternative platforms with lighter moderation (Telegram, 4chan), and extremist‑operated spaces with effectively no moderation — and said Discord functions as a central hub for targeting, communication and coordination. She explained how members of these communities use mainstream platforms to identify vulnerable individuals (searching hashtags like those tied to eating disorders or mental‑health support), recruit them through direct contact and then move them into less moderated channels where illicit activity and more extreme content circulate.

She outlined two major subcultures central to the phenomenon. The "true crime community" (TCC), she said, is an online fandom that glorifies mass killers and has been linked to multiple disrupted plots and school shootings. The COM/"7 6 4" networks, which Canuli described using the FBI's framing, engage in a mix of cybercrime, sextortion and offline violence; their members maintain "lore books" compiling compromising material for extortion and use "cut signing" and other coercive tactics to enforce control.

Canuli gave two case examples to illustrate risk and intervention points. In Pierce County, analysts identified an online account run by a 13‑year‑old who had been dressing like mass shooters and posting bomb‑making instructions; local authorities searched the home, found 23 guns and arrested the teen. According to Canuli, the teen was released with an ankle monitor and a condition to stay off social media, returned online and was re‑arrested after ISD shared additional information with police. In another high‑profile example, Canuli described a Jan. 22 attack in Antioch by a 17‑year‑old whose manifesto combined neo‑Nazi accelerationist and nihilistic content; she said the case demonstrates how ideological symbols and nihilistic motives can appear together.

In closing, Canuli urged a multi‑pronged prevention response: platform moderation alone is insufficient, she said; professional support for victims is essential; early identification and non‑criminal referrals where possible should be prioritized. She pointed listeners to ISD resources at www.isdglobal.org and said ISD is drafting a policy paper with recommendations for prevention and intervention.

The task force reserved time for a lengthy question‑and‑answer session. Members asked about ISD's monitoring availability (Canuli said analysts operate primarily during business hours), drivers behind the rise in youth involvement (she cited social media growth, youth mental‑health trends and opportunistic actors who produce manuals and guides), and the age range of those affected (Canuli said she has seen involvement as young as 8 and typically up through the early 20s).
