Investigation notes

Tishman Speyer, a prominent real estate developer and investment manager, formally reported a data security incident to Indiana regulators on September 16, 2026. The company indicated that the breach initially occurred on March 28, 2026, leading to the unauthorized access or acquisition of personal data belonging to affected individuals.

The official filing confirms that the compromised information includes 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 a broad range of sensitive data categories, particularly Social Security Numbers and direct deposit details, presents significant and long-lasting risks, including identity theft, financial fraud, and targeted phishing attempts.

As a custodian of extensive personal and financial information, Tishman Speyer had a legal and ethical obligation to implement robust security measures to protect this data. The occurrence of a breach, regardless of its specific nature, raises questions about the adequacy of the safeguards that were in place. Our ongoing investigation will examine whether the company met its duty of care under Indiana law to prevent such an incident.

If you received a data breach notification letter from Tishman Speyer, it signifies that your personal information was directly involved in this security lapse. We recommend you immediately review your credit reports for any suspicious activity, place fraud alerts or credit freezes with the major credit bureaus, and monitor all financial accounts linked to your exposed direct deposit details.

Receiving a breach notification establishes a concrete injury under the law, providing a basis to explore your legal rights. Many individuals affected by data breaches can pursue claims against the responsible company to seek compensation for potential damages, even if no immediate financial loss has occurred. Understanding these rights can be a critical step in mitigating future risks.

Our firm is actively monitoring this Tishman Speyer data breach. We offer confidential case reviews to individuals who have been impacted, helping them understand the specifics of what happened and whether they may have a claim.

What our attorneys examine

A cyberattack does not excuse a company from protecting the information it holds. We look at whether Tishman Speyer 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.

Tishman Speyer data breach questions

How many people were affected by the Tishman Speyer data breach, and what was exposed?
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. Your own letter is the best guide to what was exposed about you, since notices are usually tailored to each person.
Is the Tishman Speyer data breach letter legit or a scam?
A notice from Tishman Speyer in the mail matches the breach Tishman Speyer reported to the Indiana Attorney General on September 16, 2026. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Tishman Speyer through a phone number or website you find yourself.
Did Tishman Speyer offer free credit monitoring?
Any free monitoring Tishman Speyer is offering will be described in the notice you received, along with an activation code and a sign-up deadline. Because Social Security numbers are listed in this filing, identity monitoring and a credit freeze matter more than usual. Using the free service won't stop you from joining a lawsuit or settlement later.
Is there a Tishman Speyer data breach class action lawsuit?
Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow. This page doesn't confirm that a lawsuit has been filed against Tishman Speyer. You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
What should I do after getting the Tishman Speyer data breach notice?
Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.

Do I need a Tishman Speyer data breach lawyer or attorney?
An attorney can read your notice and tell you whether a claim makes sense. A case review here is free, and data breach cases are usually handled on contingency, so there is no upfront cost.
Can I sue Tishman Speyer over the data breach?
It depends on what was exposed, the law in Indiana and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
How much could a Tishman Speyer data breach settlement or claim be worth?
