A significant data breach at 700Credit has compromised the personal information of at least 5.6 million individuals. The Michigan-based company, which provides credit checks and identity verification for auto dealerships, reported that the breach occurred in October 2025. An unidentified hacker accessed sensitive data, including names, addresses, dates of birth, and Social Security numbers, collected from dealers over a five-month period from May to October 2025. In response to the breach, 700Credit is mailing letters to those affected, offering credit monitoring services to help mitigate the risks of identity theft. Michigan's attorney general, Dana Nessel, emphasized the importance of acting swiftly if you receive a letter from the company. She recommends individuals consider options like credit freezes or monitoring services to protect their personal information and prevent potential fraud. The situation highlights the vulnerabilities in data handling by companies that manage sensitive consumer information.
