Tishman Speyer, a prominent real estate developer and manager, announced a data security incident to Indiana authorities on September 16, 2026. This breach may have compromised the personal information of individuals associated with the company.

The breach involved the exposure of several sensitive data categories. Affected individuals may find that their Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Phone Number were compromised. Such information, particularly Social Security Numbers and financial details, can lead to serious risks like identity theft, unauthorized accounts, and tax fraud.

As a custodian of private information, Tishman Speyer had legal obligations under Indiana state law to protect this data. The occurrence of a breach often indicates potential shortcomings in the administrative, physical, or technical safeguards that were meant to prevent unauthorized access. These security measures are critical for preventing incidents of this nature.

Receiving a data breach notification letter from Tishman Speyer is a formal acknowledgment that your private data was compromised. This letter is important because it establishes the basis for understanding your legal standing and rights. It signifies that you have been directly affected by the incident.

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.
