It is advisable to regularly monitor financial accounts and credit reports for any suspicious activity. Placing a fraud alert or credit freeze with major credit bureaus (Equifax, Experian, TransUnion) can help prevent new accounts from being opened fraudulently.

Additionally, review all statements from banks, credit card companies, and other financial institutions carefully. Be wary of unsolicited emails, texts, or phone calls requesting personal information, as these could be phishing attempts. Remaining vigilant and reporting any unauthorized activity promptly are crucial measures to mitigate potential harm.

What to do if you were affected

    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.
