Cole & Van Note is investigating CoVantage Credit Union, a credit union headquartered in Wisconsin. [1]
On November 26, 2025, CoVantage Credit Union began reporting a data breach that was caused by its 3rd-party vendor service: Marquis. [2]
Publicly filed breach disclosures indicate that the incident stemmed from unauthorized access involving the credit union’s third-party service provider. The information potentially exposed may include individuals’ names, account information, Social Security numbers, and other sensitive financial data maintained in connection with banking services. Because credit unions collect and store highly confidential personal and financial records, the exposure of this type of information can increase the risk of identity theft, fraudulent account activity, and other financial misuse for affected individuals.
