Lennar Mortgage, a residential mortgage lender, filed a data breach notification with the Indiana Attorney General on August 14, 2026. The company indicated that a security incident on May 26, 2026, led to the exposure of consumer data. The specific nature of the breach was not detailed in the public filing, but it triggered the notification process required for such incidents.

The compromised information includes several categories of highly sensitive personal and financial data. According to the filing, the exposed data types are Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Return Information, Wage and Compensation Information, and Credit Score Information.

Exposure of this combination of data types can lead to a range of risks, including identity theft, financial fraud, and unauthorized access to accounts. Individuals may face challenges such as fraudulent tax filings or new accounts opened in their name. These facts are derived from the official breach notification filed with regulators.

To help mitigate potential harm, individuals affected by this incident should immediately review their bank and credit card statements for any unusual activity. It is also recommended to regularly check credit reports from the three major bureaus (Experian, Equifax, and TransUnion) for unauthorized accounts or inquiries. Placing a fraud alert or security freeze on credit files can further protect against identity theft.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
