Tishman Speyer, a global real estate developer and investment manager, formally reported a data security incident to the Indiana Attorney General's office on September 16, 2026. Public records indicate that this breach occurred on March 28, 2026, and the company has stated that the matter is presently under monitoring.

According to the official filing, the compromise exposed a range of sensitive personal identifiers. The categories of data reported as affected 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 detailed personal and financial information, like Social Security Numbers and direct deposit details, carries significant risks for affected individuals. These risks primarily involve potential identity theft, financial fraud, and unauthorized access to personal accounts.

Individuals who receive notification about this incident from Tishman Speyer are advised to take proactive measures. It is recommended to carefully review all financial statements and credit reports for any unusual or unauthorized activity. Placing a fraud alert or a security freeze on credit files with the major credit bureaus can help prevent new accounts from being opened in your name without your consent.

Furthermore, updating and using strong, unique passwords for all online accounts is a good practice. Enabling multi-factor authentication wherever possible adds an extra layer of security. Affected individuals should also remain vigilant against unexpected communications, particularly those asking for personal information, as these could be phishing attempts related to the breach.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
