Investigation notes

Lennar Mortgage, a residential mortgage lender, filed a data breach notice with the Indiana Attorney General on August 14, 2026. This notification confirms a security incident occurred on or about May 26, 2026, which led to the unauthorized access or acquisition of sensitive personal information.
