--- born: 1987-08-27 category: Extremism & Violent Networks created: 2026-05-22 location: Belo Horizonte, Minas Gerais, Brazil summary: Ciro Daniel Amorim Ferreira is a Brazilian national from Belo Horizonte designated as a Specially Designated Global Terrorist by the US Treasury and State Department on January 13, 2025, for his role as a Terrorgram Collective channel administrator running at least six Telegram channels promoting accelerationist and white supremacist propaganda. tags: - Person - TerrorgramCollective - NeoNazi - Accelerationism - Brazil - SDGT updated: 2026-05-22 --- Ciro Daniel Amorim Ferreira (born August 27, 1987, Belo Horizonte, Minas Gerais, Brazil) is a Brazilian national designated as a Specially Designated Global Terrorist (SDGT) on January 13, 2025, pursuant to Executive Order 13224, as amended by Executive Order 13886, in connection with his role as an administrator of the [Terrorgram Collective](/organizations/terrorgram-collective/). He was one of three foreign nationals designated simultaneously alongside [Noah Licul](/people/noah-licul/) (Croatia) and Hendrik-Wahl Muller (South Africa), the same action that formally designated the Terrorgram Collective itself as a terrorist organization. No Brazilian criminal charges arising from his Terrorgram activity have been publicly confirmed as of mid-2026; the designation is a US Treasury Office of Foreign Assets Control (OFAC) civil sanction, not a criminal indictment.[^1] ### Designation The US Department of State press release of January 13, 2025, described Ferreira as "a Terrorgram channel administrator" and "a Brazilian national residing in Brazil." The simultaneously issued Federal Register notice (Vol. 90, No. 10, Document 2025-00756, published January 15, 2025) formalized the OFAC designation, assigning him SDN entry number 52486 on the Specially Designated Nationals and Blocked Persons List. The OFAC record lists his address as Rua Maranhao, 1566 Apto 502, Funcionarios, Belo Horizonte, Minas Gerais; his Brazilian passport number FD621325; and his National ID number 08388816616. His alias in the SDN list is "Ciro Daniel Ferreira."[^2] As a result of the designation, all property and interests in property subject to US jurisdiction belonging to Ferreira are blocked, and US persons are generally prohibited from transactions with him. The designation activates secondary sanctions risk under section 1(b) of the executive order.[^1] ### Role in the Terrorgram Collective The State Department described Ferreira as an administrator of at least six Telegram channels, operating under the broader [Terrorgram Collective](/organizations/terrorgram-collective/) network of more than 200 Telegram channels that collectively produce and disseminate accelerationist and white supremacist propaganda. The Terrorgram Collective provides guidance and instructional materials on tactics, methods, and targets for attacks, including against critical infrastructure and government officials. Ferreira also maintained an active presence on Substack, X (formerly Twitter), YouTube, and Quora, with an inactive Instagram profile, consistent with the Terrorgram ecosystem's use of multiple platforms to preserve redundancy against takedowns.[^1][^3] In 2023, Brazilian researcher [Michele Prado](/people/michele-prado/), founder of the NGO [Stop Hate Brasil](/organizations/stop-hate-brasil/), submitted a report to Brazil's ABIN (Agência Brasileira de Inteligência) and the Ministry of Justice and Public Security that identified Telegram channels linked to Ferreira and other members of the Terrorgram network operating in Brazil. This report represented one of the first formal institutional flaggings of Ferreira's channels to Brazilian authorities.[^3] ### Prior Criminal Record Brazilian state-level records, as reported by Brazilian media following the 2025 designation, indicate that Ferreira has two prior prison records from units in Minas Gerais, for crimes including theft, bodily injury, and false imprisonment. He was imprisoned twice, in 2015 and 2016, receiving court-issued release warrants in both instances. These offenses predated his documented Terrorgram activity and are unrelated to extremism or terrorism charges.[^4] ### Pre-Extremism Activity According to OSINT sources cited in contemporaneous Brazilian and Latin American coverage, Ferreira previously directed a space in Belo Horizonte "dedicated to the promotion of the interests and rights of children and adolescents through information and communication technologies," an activity consistent with a civic or educational technology orientation before his documented involvement in accelerationist networks.[^4] ### Aracruz Attack and Wolf Boy Winter The US government did not publicly detail in the January 2025 designation documents whether Ferreira had direct contact with [Gabriel Rodrigues Castiglioni](/people/gabriel-rodrigues-castiglioni/), who carried out the [2022 Aracruz School Shootings](/events/2022-aracruz-school-shootings/) on November 25, 2022. The State Department's broader Terrorgram designation cited the Aracruz attack as one of the attacks motivated and facilitated by the Terrorgram network, alongside the October 2022 LGBTQ+ bar shooting in Bratislava and subsequent attacks. The Aracruz connection to Terrorgram was most specifically documented through [Dallas Humber](/people/dallas-humber/)'s prosecution: Humber and [Matthew Robert Allison](/people/matthew-robert-allison/) discussed a Brazilian contact planning a racially motivated school attack approximately one month before the attack, and Humber subsequently created saint cards for Castiglioni.[^5] A figure using the Terrorgram pseudonym "Wolf Boy Winter" posted a video still from Aracruz attack surveillance footage to a major Terrorgram channel approximately two days after the November 25, 2022 attack, and contributed multiple pages to "The Hard Reset," one of Terrorgram's primary propaganda publications. Michele Prado's 2023 ABIN report identified channels linked to "Wolf Boy Winter." No public source has established the identity of "Wolf Boy Winter" as Ferreira; the two remain separately documented nodes in publicly available records.[^3] ### International Designations The January 13, 2025, action designated Terrorgram as a terrorist organization and simultaneously named three foreign administrators in three different countries, a structure reflecting the network's explicitly transnational character. Noah Licul (Croatia), designated as a "senior member," had been active in the network since at least 2019 under the alias "buntovnik" and is documented in the [Feuerkrieg Division](/organizations/feuerkrieg-division/) to Terrorgram personnel lineage. Hendrik-Wahl Muller (South Africa) was described as a channel administrator, parallel to Ferreira's role description.[^1] The Terrorgram Collective had already been designated by the [United Kingdom](/places/united-kingdom/) (April 2024, SI 2024/569), [Australia](/places/australia/) (F2025L00762), and [Canada](/places/canada/) (SOR/2025-263) before and following the US action. None of these proscription instruments publicly named Ferreira specifically. The US action of January 13, 2025 was the first government designation to name a Brazilian national as a Terrorgram Collective administrator.[^1][^6] [^1]: US Department of State, "Terrorist Designations of The Terrorgram Collective and Three Leaders," January 13, 2025. https://2021-2025.state.gov/office-of-the-spokesperson/releases/2025/01/terrorist-designations-of-the-terrorgram-collective-and-three-leaders/ [^2]: Federal Register, Vol. 90, No. 10, Document 2025-00756, "Specially Designated Global Terrorist Designations of The Terrorgram Collective, Ciro Daniel Amorim Ferreira, Noah Licul, and Hendrik-Wahl Muller," January 15, 2025. https://www.federalregister.gov/documents/2025/01/15/2025-00756/specially-designated-global-terrorist-designations-of-the-terrorgram-collective-ciro-daniel-amorim; OFAC SDN Entry 52486, sanctionssearch.ofac.treas.gov/Details.aspx?id=52486 [^3]: GNET (Global Network on Extremism and Technology).
