Blaze Credit Union Members Impacted by Third-Party Data Breach Affecting 235,000
A data breach at Marquis Software Solutions, a third-party vendor serving financial institutions, has potentially exposed the personal information of over 235,000 members of Blaze Credit Union. The incident occurred at the vendor level, though details on the exact cause or timeline of the breach remain undisclosed.
Blaze Credit Union began notifying affected members via mailed letters in early December, offering complimentary credit monitoring and identity protection services through Marquis. While officials report no evidence of misuse or attempted misuse of the compromised data, they advise members to monitor accounts for suspicious activity, watch for phishing attempts, and review credit reports for unauthorized accounts.
Marquis Software Solutions provides services to multiple financial institutions, though the breach appears isolated to Blaze Credit Union’s member data. The credit union has not specified the types of information exposed but emphasizes proactive measures to mitigate risks for those impacted. Further updates may follow as investigations continue.
