At least 5.6 million people's names, addresses, dates of birth, and Social Security numbers were stolen in a data breach at 700 Credit, which operates a credit reporting and identity verification service for auto dealers across the United States.
In a statement on its website, the Michigan-based company blamed the October data breach on an unknown malicious actor.
According to the Michigan Attorney General's Office, hackers stole personal data collected from dealers between May and October 2025.
The credit monitoring service said it is currently mailing letters to individuals whose information was stolen in the data breach.
“If you receive a letter from 700 Credits, please do not ignore it,” said Michigan Attorney General Dana Nessel. “It's important that those affected by this data breach take steps to protect their information as soon as possible. Credit freezes and monitoring services can go a long way in preventing fraud. I encourage Michiganders to use the tools available to them to keep their identities safe.”
