Your Rights and Next Steps
If you received a notice about this data breach, it is important to take steps to protect yourself. Even if there is no evidence of misuse, the exposure of Social Security numbers and names can put individuals at risk for identity theft and fraud.
Here are some actions you can take:
- Monitor your credit reports for any unauthorized activity. You are entitled to a free credit report from each of the three major credit bureaus every twelve months.
- Consider placing a fraud alert on your credit file by contacting one of the credit bureaus. This makes it harder for identity thieves to open accounts in your name.
- You can also place a security freeze on your credit report, which restricts access to your credit file and can prevent new accounts from being opened without your consent.
- Review your financial account statements regularly and report any suspicious activity to your financial institutions.
- If you believe you are a victim of identity theft, contact the Federal Trade Commission and your state attorney general’s office for guidance on next steps and to file a report.
