What Information Was Breached?

What You Can Do

TKD stated that it is providing 12 months of credit monitoring through TransUnion at no cost to individuals whose personal information was potentially affected.
You should also monitor your credit reports, financial accounts, and account statements for suspicious activity. If you notice unfamiliar accounts, unauthorized transactions, or signs of identity theft, report them immediately to your financial institution and appropriate authorities.
Affected individuals may also consider placing a fraud alert or credit freeze on their credit files. A fraud alert tells creditors to take additional steps to verify your identity before opening new accounts. A credit freeze can help prevent new credit accounts from being opened in your name without your authorization.
Because Social Security numbers may have been exposed, you should also watch for signs of tax-related fraud.
