What we know

Castle Management LLC, a real estate asset management firm operating in Indiana, has confirmed a data breach, reporting the incident on August 25, 2026. The breach affects individuals whose personal information was entrusted to the company, including current and former tenants, employees, and associated contractors. While the exact cause is unspecified, such incidents often point to unauthorized access to internal systems.

The compromised data is extensive, encompassing a dangerous array of sensitive personal details. The exposed categories include Full Name, Social Security Number, Date of Birth, Mailing Address, Banking Account Details, Driver's License Number, Background Check Information, and Lease and Payment History.

The exposure of such sensitive information carries substantial risks.

The theft of Driver's License Numbers can also facilitate various forms of impersonation.

If you have received a data breach notification letter from Castle Management LLC, it is important to take proactive steps. Review all financial statements and credit reports for any unusual activity. Consider placing a fraud alert or credit freeze on your credit files to prevent new accounts from being opened in your name without your knowledge.

Understanding your legal rights and options in the wake of a data breach is a critical step; a qualified attorney can assess your specific situation and provide guidance.
