Steps to take if your information was exposed

• Place a credit freeze with all three credit bureaus by contacting Equifax (1-800-525-6285), Experian (1-888-397-3742) and TransUnion (1-800-680-7289) to help prevent new accounts from being opened using stolen personal information.
• Request free credit reports at AnnualCreditReport.com and review them carefully for any unfamiliar accounts, inquiries or other suspicious activity.
• Monitor bank accounts and financial statements for unauthorized charges or withdrawals and report anything suspicious to your financial institution right away.
• Consider placing a fraud alert with one of the three major credit bureaus, which will require creditors to take additional steps to verify your identity before issuing new credit.
• Report suspected identity theft to the Federal Trade Commission at IdentityTheft.gov, where you can create a personalized recovery plan.
• Be cautious of phishing attempts that reference TSU One Holdings or this data breach by name, as scammers sometimes use real breach events to trick people into sharing additional personal information through fake emails, texts or phone calls.
