Big Brothers Big Sisters of Eastern Missouri was the subject of a data breach notification filed with the IN Attorney General. The AG filing was recorded on September 14, 2026. The breach or discovery date reported in the filing is March 5, 2026.
From the AG filing description
Big Brothers Big Sisters of Eastern Missouri operates as a prominent community-based mentoring organization dedicated to creating and supporting one-to-one mentoring relationships that ignite the power and promise of youth. In the course of fulfilling this vital mission, the organization collects, processes, and maintains a vast repository of highly sensitive personal information. This data ecosystem encompasses comprehensive records pertaining to participating children ('Littles'), volunteer mentors ('Bigs'), parents, guardians, donors, and organizational personnel. Because the organization facilitates deep, trust-based community programs, it routinely gathers intimate background details, contact histories, and demographic markers necessary to vet participants and ensure child safety. In 2026, Big Brothers Big Sisters of Eastern Missouri formally reported a significant data security incident to the Indiana Attorney General, highlighting vulnerabilities within its digital infrastructure. While the exact vectors of the compromise continue to be analyzed, incidents affecting non-profit and community service organizations typically involve sophisticated cyberattacks such as unauthorized access to internal database servers, ransomware deployment, or third-party vendor compromises. Because non-profits often operate with constrained IT budgets relative to corporate entities, malicious actors frequently target them as softer entry points to exfiltrate bulk personal records stored across legacy databases and cloud storage repositories. The exposure resulting from this breach compromises several categories of sensitive information, each carrying distinct and severe risks for the affected individuals. The compromised data frequently includes full names, dates of birth, Social Security numbers, home addresses, contact information, background check reports, and potentially financial or banking details provided by donors and employees. The unauthorized release of Social Security numbers and dates of birth exposes victims to immediate and long-term threats of identity theft, fraudulent credit card applications, and unauthorized loan openings. Furthermore, the exposure of background check histories and mentoring application details can compromise the personal privacy and security of vulnerable youth and their families, leaving them exposed to targeted phishing campaigns, social engineering, and fraud. As an organization entrusted with sensitive personal records, Big Brothers Big Sisters of Eastern Missouri had a clear legal and ethical obligation to implement robust administrative, technical, and physical safeguards to secure its digital environment. Under state consumer protection statutes, such as the Indiana Deceptive Consumer Sales Act, along with common law negligence standards, organizations that collect personally identifiable information owe a duty of care to protect that data from foreseeable cyber threats. The occurrence of a successful breach strongly suggests potential failures in maintaining adequate cybersecurity measures, such as failing to patch known vulnerabilities, neglecting to deploy multi-factor authentication, or failing to properly monitor network traffic for suspicious activity. Receiving a data breach notification letter from Big Brothers Big Sisters of Eastern Missouri serves as formal legal notice that your private information was compromised due to the organization's security failures. Under the law, this notification establishes the legal standing necessary to participate in a class action lawsuit aimed at holding the organization accountable for failing to safeguard sensitive data. Importantly, victims do not need to prove that they have already suffered actual financial loss or identity theft to seek legal recourse; the increased risk of future harm and the time and expense required to mitigate that risk are sufficient grounds for action. Our law firm is investigating this data breach on a contingency fee basis, meaning affected individuals pay no upfront costs or out-of-pocket fees unless financial recovery is successfully obtained.
Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Phone numbers exposed in breaches are used for SIM swapping attacks — hijacking your number to bypass two-factor authentication on financial accounts.
You may have been affected by the Big Brothers Big Sisters of Eastern Missouri data breach if:
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
Applicable State Law
This breach was reported under the Indiana data breach notification law, which mandates notification and establishes your right to seek damages.
No. Under Indiana data breach notification law and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Big Brothers Big Sisters of Eastern Missouri does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Big Brothers Big Sisters of Eastern Missouri during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
Most data breach class actions resolve within 18 to 36 months, though timelines vary by court and complexity. Your participation requires minimal effort — typically completing a claim form. Our office handles all litigation; you are notified when a settlement is reached.
