From the document: "The Office of Intelligence and Analysis of the Department of Homeland Security presents the 2025 Homeland Threat Assessment, which provides insights from across the Department and other homeland security stakeholders to identify the most direct, pressing threats to our Homeland during the next fiscal year (FY). This Assessment organizes evolving threats to homeland security missions arising from the dynamic terrorist threat, the increasing complexities straining the immigration system, transnational organized crime, proliferating cyber threats, and geopolitical strategic competition into four sections: Public Safety and Security, Border and Immigration Security, Critical Infrastructure Security, and Economic Security. This Assessment employs a traditional intelligence assessment format in which summary assessment paragraphs are followed by bullets with additional details that underpin the assessment. We note that many of the threat actors and efforts addressed in this Assessment appear in multiple sections as they cut across mission areas and interact in complex and, at times, reinforcing ways. Throughout this Assessment, we also examine enduring issues, such as the development and proliferation of new technologies and climate change, which involve various mission areas and impact multiple threats. Definitions for terms and additional contextual notes are included at the end of this document."
