The National Society Sons of the American Revolution (NSSAR), a US-based non-profit, reportedly suffered a data breach in April 2026. An unidentified party offered a 45.66 GB database containing over 16,000 files for sale on the dark web. The breach was detected through dark web monitoring.
The compromised data allegedly included membership analytics for over 37,000 NSSAR members, genealogical research library files, historical tax records, and administrative documents such as museum plans and budgets. Specific information about the number of affected individuals or whether financial or medical data was exposed remains unclear. No official confirmation or detailed breakdown of the data types has been publicly released by NSSAR.
Details about this incident are still emerging and may be delayed.
