Florida Credit Union customers were impacted by a data security incident stemming from a cyberattack on third-party vendor Marquis Software Solutions. Marquis detected unauthorized network activity on August 14, 2025, which reportedly involved a ransomware event. The incident was isolated to the vendor's internal systems and did not directly compromise Florida Credit Union's internal networks.
The compromised files potentially contained customer personal and financial details. Exposed data types included names, mailing addresses, telephone numbers, dates of birth, Social Security numbers, taxpayer identification numbers, and financial account information. The total number of impacted Florida Credit Union members has not been publicly confirmed.
Notice letters were subsequently submitted to regulators, including the New Hampshire Attorney General's Office, regarding the third-party compromise. As investigations continue and consumer notifications roll out, further specifics regarding the scope of exposed information may be clarified.
