Start Free Review →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.
MemberSource Credit Union was the subject of a data breach notification filed with the IN Attorney General. The AG filing was recorded on May 7, 2026. The breach or discovery date reported in the filing is June 3, 2025.
From the AG filing description
MemberSource Credit Union operates as a member-owned financial cooperative, providing essential banking services such as savings and checking accounts, consumer loans, mortgages, and investment management to individuals and families across Indiana. Because credit unions function as primary financial hubs for their members, they accumulate vast repositories of deeply sensitive personal and financial data. To facilitate daily transactions, process loan applications, and maintain secure accounts, MemberSource Credit Union must collect and retain comprehensive identifying documentation, making them a prime target for cybercriminals seeking to exploit high-value personal information. In 2026, official notifications regarding a major data security incident were reported to the Indiana Attorney General involving MemberSource Credit Union. While the precise mechanics of the intrusion continue to be investigated, breaches impacting financial institutions typically stem from sophisticated cyberattacks such as unauthorized database access, ransomware deployments, or third-party vendor compromises. These incidents often occur when malicious actors exploit vulnerabilities in legacy infrastructure, bypass network perimeters, or leverage compromised employee credentials to infiltrate internal systems where sensitive member records are stored. The exposure resulting from this security failure compromises a wide array of highly confidential data categories. When financial institution databases are breached, threat actors frequently access full names, Social Security numbers, dates of birth, financial account numbers, routing numbers, and credit histories. The unauthorized disclosure of this information exposes victims to severe, long-term risks, including fraudulent credit applications, unauthorized bank withdrawals, tax refund fraud, and identity theft. Unlike transient data leaks, compromised financial identifiers and government-issued numbers cannot be easily changed, leaving affected individuals vulnerable to persistent financial threats for years to come. As a financial institution, MemberSource Credit Union is bound by stringent regulatory frameworks, most notably the Gramm-Leach-Bliley Act (GLBA) and the Federal Trade Commission (FTC) Act. These laws mandate that financial entities implement rigorous administrative, technical, and physical safeguards to protect non-public personal information against foreseeable threats and unauthorized access. The occurrence of a data breach of this magnitude strongly indicates a potential failure to maintain adequate security controls, encryption standards, and intrusion detection systems, raising significant questions regarding whether the institution met its legal duty of care. Receiving an official data breach notification letter from MemberSource Credit Union is a clear indication that your personal and financial information was compromised due to inadequate security measures. Under the law, the receipt of this notice establishes legal standing to participate in a class action lawsuit aimed at holding the institution accountable for its negligence. Crucially, victims do not need to demonstrate actual financial loss or identity theft to pursue legal claims; the increased risk of future harm is sufficient. Our law firm handles these complex class action cases on a strict contingency fee basis, meaning you pay nothing out of pocket and owe no legal fees unless we successfully recover compensation on your behalf. Given the critical role that credit unions play in managing household wealth and financial security, an incident affecting an institution of this scale carries profound implications for its members. Breaches within the financial sector not only disrupt daily banking operations but also erode consumer trust, placing the burden of mitigation squarely on the shoulders of unsuspecting account holders who relied on the institution to keep their most sensitive assets secure.
You may have been affected by the MemberSource Credit Union data breach if:
Common categories of compensation in data breach class actions
The hours spent responding to a data breach — canceling accounts, contacting credit bureaus, updating passwords, and investigating fraud — represent compensable economic harm in data breach litigation.
Once your SSN is exposed, protection becomes an ongoing expense. Plaintiffs in data breach settlements have recovered costs for credit freezes, identity protection subscriptions, and time spent dealing with fraudulent accounts — sometimes covering multiple years of exposure.
Fees charged to close and reopen accounts, issue replacement cards, or dispute fraudulent transactions are recoverable in data breach litigation. So are the costs of overdrafts, late payments, and credit damage caused by unauthorized activity.
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.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
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 MemberSource Credit Union 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 MemberSource Credit Union during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
