Individuals who receive official notification about this data breach are advised to take proactive steps to protect themselves. It is recommended to regularly review credit reports for any unusual activity and to carefully check Explanation of Benefits (EOB) statements from health insurance providers for any unauthorized medical procedures or billing. Considering a fraud alert or security freeze on credit files can help prevent new accounts from being opened fraudulently. Maintaining vigilance over all personal and financial accounts is a crucial protective measure.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Check for medical identity theft
Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.
Stay alert to targeted scams
Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.
Keep your notification letter
Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
