Sun Communities Inc data breach

Clerk's notes

Sun Communities Inc, a company operating in residential property management and real estate development, officially reported a data security incident to the Indiana Attorney General on February 6, 2026. This breach, which occurred on December 25, 2025, is currently under monitoring as authorities and the company investigate its full extent.

The compromised information includes several categories of highly sensitive personal data. Specifically, the breach involved individuals' Full Name, Social Security Number, Date of Birth, Residential Address History, Driver License Number, Banking Account and Routing Numbers, Lease Agreement and Payment History, and Background Check and Screening Files. The exposure of such detailed information places affected individuals at increased risk of identity theft, financial fraud, and other related harms.

As a custodian of private data, Sun Communities Inc had a legal obligation to implement and maintain reasonable cybersecurity safeguards to protect the information it collects. The occurrence of this data breach suggests that those protective measures may have been insufficient, allowing unauthorized access to confidential resident and employee records.
