Steps to take if your information was exposed
- Place a fraud alert or credit freeze with Equifax (1-800-525-6285), Experian (1-888-397-3742) and TransUnion (1-800-680-7289) to help prevent anyone from opening new financial accounts using stolen personal information.
- Request free credit reports at AnnualCreditReport.com and review them carefully for any unfamiliar accounts, hard inquiries or other suspicious activity that could indicate fraud.
- Report a compromised passport to the U.S. Department of State if passport information may have been exposed, as a stolen passport number could be used to create fraudulent identity or travel documents.
- Monitor health insurance statements closely for any unfamiliar services, claims or charges, since compromised medical records could be used to commit medical identity theft.
- Consider filing an identity theft report with the Federal Trade Commission at IdentityTheft.gov if there are any signs that personal information has been misused.
- Be cautious of phishing attempts that reference Lumio Dental or this data breach by name, as scammers frequently use real breach notifications to trick people into sharing additional sensitive personal information.
