Investigation notes

Castle Management LLC, a firm managing extensive real estate portfolios, has formally reported a data breach to the Indiana Attorney General on August 25, 2026. The incident, which occurred on or about September 18, 2025, involved an unspecified breach type, leading to the exposure of confidential consumer and employee data entrusted to the company.

The compromised records from Castle Management LLC include a wide array of highly sensitive personal details. The exposed data categories are 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. These specific data points are often targeted by malicious actors due to their utility in identity theft and financial fraud schemes.

Exposure of information like Social Security Numbers and Banking Account Details creates a significant risk for identity theft, unauthorized financial transactions, and fraudulent credit applications. Additionally, the compromise of Driver's License Numbers and Background Check Information can lead to further personal privacy intrusions and targeted scams, making it crucial for affected individuals to remain vigilant.

Companies like Castle Management LLC are legally obligated under state and federal regulations, including Indiana's data breach notification laws, to implement robust security measures to protect the personal data they collect and store. The occurrence of a breach involving such sensitive information suggests a potential failure in upholding these duties, which typically involve maintaining secure systems, monitoring for threats, and managing access controls effectively.

If you have received a data breach notification letter from Castle Management LLC, it signifies that your private information was part of this compromise. Receiving such a notice establishes your legal standing to understand your rights and explore potential legal recourse. It is important to note that you do not need to prove actual financial loss or identity theft to pursue a claim, as the increased risk of future harm can be sufficient.

If you believe your data was exposed, we offer a free, no-obligation case review to discuss your situation and evaluate your potential options.

A cyberattack does not excuse a company from protecting the information it holds. We look at whether Castle Management LLC used reasonable security, how long it kept the data, and how quickly it told the people affected. Those questions decide whether a class action or individual claim is possible. Read more on how ransomware lawsuits work, or browse other incident files in Indiana.
