Save your letter and its key dates
Keep the original notice, envelope, and any emails together in a safe place. Note every date the letter lists, such as the incident date, any enrollment deadline, or a response cutoff. For context, The public filing reports an incident date of between September 16, 2025 and October 8, 2025, and public notices were reported between December 15, 2025 and December 16, 2025.

Verify any monitoring offer before enrolling
Your own letter, not the public filing, will state whether free credit or identity monitoring is offered to you, what it covers, and its enrollment deadline. Before using any link, phone number, or enrollment code in the notice, confirm the letter is genuine by contacting the company through a website or statement you already trust.
Protect your accounts and credit
Even when the filing does not identify sensitive categories, protect the accounts tied to the information in your letter, use strong unique passwords, and watch for unfamiliar activity. If your letter lists sensitive information such as a Social Security number or financial details, consider a free credit freeze.
