Public filings do not specify the exact categories of personal information exposed, nor do they state the number of individuals impacted. However, any breach of personal information warrants attention from those potentially affected.

Individuals who may be affected by this incident should remain vigilant for unusual activity. It is advisable to review financial account statements and monitor credit reports for any unfamiliar transactions or inquiries. Access to free credit reports is available annually from each of the three major credit bureaus.

Consider placing a fraud alert or a security freeze on your credit files to prevent unauthorized access. Be cautious of unsolicited communications, especially those requesting personal or financial details, as these could be phishing attempts related to the incident.

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.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • 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.

  • 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.
