All available information regarding this event is derived from official regulatory filings, which serve as the verified public record for such data security notifications.

For those who may be affected, it is generally recommended to exercise caution. Regularly monitor your financial account statements and other personal records for any unusual activity that could indicate unauthorized use of your information.

Additionally, consider placing a fraud alert on your credit reports with the three major credit bureaus: Equifax, Experian, and TransUnion. This makes it more difficult for identity thieves to open new accounts in your name. Remain vigilant against unexpected communications that request personal data.

What to do if you were affected

These general steps can help limit the risk of identity theft and fraud after any data breach.

  • 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.
