What we know

Tishman Speyer, a prominent global real estate firm, confirmed a data security incident to the Indiana Attorney General on September 16, 2026. This notification indicates that personal information was compromised during an event that took place on March 28, 2026. As a company managing extensive commercial and residential properties, Tishman Speyer collects a substantial amount of sensitive data from its workforce, partners, and tenants.

The breach exposed several categories of sensitive personal information. These include Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Phone Number. The exposure of such comprehensive personal and financial details can lead to severe and lasting risks for those affected.

Individuals whose data was compromised face a heightened risk of identity theft, various forms of financial fraud, and targeted phishing scams. Attackers often use stolen Social Security Numbers to open new lines of credit, file fraudulent tax returns, or access existing accounts. Direct Deposit Account Details could be exploited for unauthorized financial transactions or account takeover.

As a custodian of private data, Tishman Speyer is obligated under Indiana state law to implement robust security measures to protect this information. The occurrence of a breach involving such critical data categories suggests potential vulnerabilities in their digital infrastructure, possibly indicating a failure to uphold these security duties.

If you have received a data breach notification letter from Tishman Speyer, it is important to review it carefully. Consider monitoring your financial accounts and credit reports for any suspicious activity. This letter is official confirmation that your personal data was compromised.

Receiving a notification letter establishes a concrete injury and the legal standing necessary to participate in a class action lawsuit. You do not need to demonstrate actual financial loss to seek justice; the increased risk of future harm alone is legally actionable. We offer a free, no-obligation case review to help you understand your rights and options.

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

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

The filing does not give a count of affected people and lists the following information as involved: Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, Phone Number.
