Public breach notifications — last 365 days

Material cybersecurity incident disclosures filed under SEC Form 8-K Item 1.05 (final rule effective 2023-12-18) plus regulator enforcement actions. This is the unattributed layer — most disclosures do not name an attacker. When the victim org matches a name in our actor-attributed catalog, the row links to that actor entry; otherwise the row is shown with "unattributed".

21 notification(s) in the window · 1 publicly attributed to a known actor in our catalog (5%). Most attribution comes weeks or months after the disclosure; this share grows as the underlying actor data fills in.
