CorrectionPublished Sep 26, 2026

Correction: we date this filing March 1, 2022, not 3/1/2021 as the Montana Department of Justice's breach register prints it. That date is earlier than the start of the breach the same register row reports (7/4/2021), and the Indiana, Massachusetts and Maine breach registers list this notice on March 1, 2022, the date of the notification letter Montana published for this entry.
