How this tracker works
Every state requires organizations to notify residents of breaches of personal information, and some also require a copy of the notice to the attorney general, who publishes it. We read the public lists of California, Washington and Oregon twice a day and keep the last 13 months.
“Residents affected” counts only that state’s residents, not the breach’s total size. The same breach often appears in several states’ lists. A notice means an organization reported a breach; the notice itself, linked from each name where the state publishes it, explains what happened.
