Marquis Software Solutions, a fintech vendor providing digital marketing and communication services to numerous US banks and credit unions, has warned that a ransomware data breach has compromised sensitive personal information of thousands of customers. The cybersecurity incident was first detected on August 14, 2025, when Marquis identified suspicious activity on its network, triggering an immediate investigation involving external cybersecurity experts and law enforcement agencies[1][2][3].
Despite Marquis paying the ransomware demand, the attackers retained and distributed stolen data on criminal marketplaces, exacerbating the impact of the breach[1]. The exposed data includes highly sensitive personally identifiable information (PII) such as full names, addresses, phone numbers, dates of birth, Social Security numbers, and financial account details. This type of information can enable identity theft, fraudulent loan applications, account takeovers, and other financial crimes[1][2].
By late October 2025, Marquis began notifying affected financial institutions and customers, including Community 1st Credit Union in Iowa and CoVantage Credit Union in Wisconsin, among others. The breach has affected over 6,800 individuals nationwide, including thousands of Iowa residents[1][2]. Marquis formally notified the Iowa Attorney General’s Office in early November 2025 as part of regulatory compliance[1].
In response to the breach, Marquis has implemented enhanced security measures such as multi-factor authentication, firewall patching, geo-IP filtering, and endpoint detection and response tools to prevent future intrusions[2]. The company is also offering affected individuals complimentary identity protection services through Epiq Privacy Solutions ID, which provides credit monitoring, dark web surveillance, identity restoration, and fraud resolution support for 12 to 24 months[1][3].
Authorities and cybersecurity experts emphasize that individuals impacted by the breach should take immediate precautions, including enrolling in credit and identity monitoring, reviewing financial statements closely, and placing fraud alerts on their credit files. Residents in states with enhanced privacy laws, such as California, have additional protections under laws like the California Consumer Privacy Act (CCPA)[2].
Legal actions are also underway, with class action lawsuits being initiated to seek compensation for those affected by Marquis’s data breach[4]. Marquis continues to cooperate with federal and state agencies as investigations proceed.
This breach underlines the growing cybersecurity risks facing financial technology providers and the critical need for robust data protection to safeguard consumer information within the banking ecosystem.
