What we know

Tishman Speyer, a globally recognized real estate developer and manager, reported a data security incident to the Indiana Attorney General, affecting individuals whose personal information was entrusted to the company. This breach, which occurred on March 28, 2026, became publicly known through a formal filing on September 16, 2026, indicating a compromise within their digital infrastructure. The company has stated it is currently monitoring the situation following this disclosure.

The breach exposed a range of highly sensitive data categories. The information compromised included individuals' Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Phone Number. Such data is typically maintained by large enterprises like Tishman Speyer for employee records, tenant management, or business partner interactions.

Exposure of this combination of personal and financial identifiers creates significant risks for affected individuals. With a Full Name, Social Security Number, and Date of Birth, malicious actors can attempt to open new lines of credit, file fraudulent tax returns, or gain unauthorized access to existing accounts. Direct Deposit Account Details, coupled with Wage and Compensation Information, could lead to financial fraud, unauthorized transactions, or targeted phishing scams designed to steal more assets.

As a custodian of private personal and financial data, Tishman Speyer has a legal obligation to implement robust administrative, physical, and technical safeguards. The occurrence of a data breach of this magnitude suggests that the security measures in place may not have been sufficient to prevent unauthorized access to sensitive records. This raises questions about the company's adherence to state data protection standards and its duty to safeguard individual information.

If you received a data breach notification letter from Tishman Speyer, it is important to take proactive steps immediately. You should consider placing a fraud alert or freezing your credit with the major credit bureaus, carefully review all financial statements for any suspicious activity, and change passwords for any online accounts that might use similar credentials.

Beyond these immediate protective measures, you may also be entitled to legal recourse for the increased risk and potential harm caused by this data exposure. Our firm offers a free, no-obligation case review to help you understand your options and assess any potential claims related to this incident.

After the Tishman Speyer incident: what to do and your options

What should I do after getting the Tishman Speyer data breach notice?

Did Tishman Speyer offer free credit monitoring?
