What we know

Lennar Mortgage, a prominent residential mortgage lender, reported a data security incident to Indiana authorities on August 14, 2026. The company stated that the breach occurred on May 26, 2026, leading to the unauthorized access of sensitive personal and financial data belonging to individuals.

The compromised information included a range of critical details: Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Return Information, Wage and Compensation Information, and Credit Score Information.
