About Valley Strong Credit Union
Valley Strong Credit Union is a member-owned financial cooperative based in Bakersfield, California. Founded in 1938, it serves over 300,000 members across California’s Central Valley, providing a wide range of banking services including checking and savings accounts, loans, credit cards and digital banking.
As a credit union, Valley Strong operates on a not-for-profit model, returning earnings to members through better rates and lower fees. The institution is governed by a volunteer board elected by its members and is known for its focus on community involvement and financial education initiatives.
What Happened?
In August 2025, Valley Strong Credit Union was affected by a data breach through its third-party vendor, Marquis Software Solutions Inc., which provides digital and physical marketing services. On Aug. 14, 2025, Marquis detected suspicious activity and determined it was the victim of a ransomware attack. The breach was limited to Marquis’ environment and did not impact Valley Strong’s internal systems.
The investigation revealed that an unauthorized party accessed Marquis’ network and may have acquired files containing sensitive information. On Oct. 27, 2025, Marquis determined that personally identifiable information (PII) had been exposed.
Possible Information Exposed
- Names
- Addresses
- Phone numbers
- Social Security and Taxpayer ID numbers
- Financial account information
- Dates of birth
The breach affected at least 1,640 individuals in Washington and 54 in Maine, with notifications sent to impacted consumers beginning Nov. 26, 2025. Marquis has stated there is no evidence so far of misuse of the exposed information.
