The exposed data types include Full Name, Date of Birth, Social Security Number, Mailing Address, Email Address, Background Check Records, Phone Number, and Donation and Payment History.

Organizations entrusted with sensitive personal records, such as Big Brothers Big Sisters of Eastern Missouri, bear a clear legal and ethical obligation to protect that data.

The occurrence of this data breach indicates that those safeguards may have been insufficient to prevent unauthorized access to your private information.
Receiving a data breach notification letter serves as formal confirmation that your personal information was compromised due to this incident. This notification establishes the legal standing necessary to explore your options for recourse. Importantly, you do not need to prove that you have already suffered direct financial loss or identity theft; the increased risk of future harm and the time and expense required to monitor and mitigate that risk can be sufficient grounds for legal action.
