Blaze Credit Union Data Breach Exposes Sensitive Information of Hundreds of Thousands On January 5, 2026, Blaze Credit Union, a Minnesota-based financial institution, disclosed a cybersecurity incident that compromised the personal data of potentially hundreds of thousands of individuals. An unauthorized actor gained access to Blaze’s network, potentially acquiring records containing personally identifiable information (PII), including names, addresses, dates of birth, and Social Security numbers. The breach is currently under investigation by Lynch Carpenter LLP, a national class action law firm specializing in data privacy litigation. The firm is reviewing potential claims against Blaze on behalf of affected individuals. No further details on the breach’s origin, timeline, or specific number of impacted customers have been released. Blaze Credit Union has not yet provided public guidance on mitigation steps for those affected, though the exposure of sensitive data heightens risks of identity theft and fraud. The incident underscores ongoing vulnerabilities in financial sector cybersecurity.

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.
