Hogan Lovells, attorneys for Home Depot, sent the New Hampshire Attorney General a notification of the breach. Their letter, dated September 9, reiterates that they first learned of a possible breach on September 2 and confirmed it on September 9.
Home Depot still doesn’t have exact numbers, it seems. The letter says that “At this time we cannot determine how many residents of the state are affected.” Home Depot therefore notified every New Hampshire resident who used a payment card in their stores from April on, including an offer of free credit monitoring services.
You can read their notification (pdf) with the attached notice to consumers.
