2025-dbir-data-breach-investigations-report
The 2025 Verizon Data Breach Investigations Report (DBIR) analyzes 22,052 security incidents (12,195 confirmed breaches) across 139 countries from Nov 1 2023 to Oct 31 2024. Using the VERIS framework, the report presents methodology, bias considerations, and a deep dive into incident classifications, actor motives, and action varieties. It details industry‑specific findings (Healthcare, Manufacturing, Retail, Public Sector, etc.), highlights the rise of espionage‑motivated attacks, the growing impact of third‑party breaches, and the stark differences between small‑ and large‑organization threat landscapes. Regional analysis (APAC, EMEA, LAC, NA) shows pattern convergence on System Intrusion and ransomware, with notable variations in actor composition and data types stolen. A month‑by‑month “Year in Review” chronicles zero‑day exploits, ransomware operations, nation‑state campaigns, and major takedowns. The report concludes with methodological transparency, bias discussion, a call for better disruption practices (including guidance from the U.S. Secret Service), and a comprehensive list of contributing organizations. The findings aim to inform security leaders, policymakers, and researchers about current threat trends and actionable mitigation priorities.
