Builders FirstSource Inc, a major supplier and manufacturer, reported a data security incident to the Indiana Attorney General. The company disclosed that the breach took place on April 22, 2026, with the official filing occurring several months later on August 7, 2026. This notification is part of the company's obligation to inform state regulators about security incidents affecting personal information.

The compromised information includes Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, and Phone Number. These categories of data are frequently targeted in cyberattacks due to their value to malicious actors.

Exposure of such sensitive personal data carries significant risks for individuals. Social Security Numbers and Dates of Birth can be used for identity theft, leading to fraudulent accounts or unauthorized access to government benefits. Direct Deposit Account Details, Wage and Compensation Information, and Tax Return Information could enable financial fraud, unauthorized transactions, or tax-related scams.

Individuals who receive a breach notification from Builders FirstSource Inc should take immediate steps to protect themselves. It is recommended to regularly review financial account statements and credit reports for any suspicious activity. Placing a fraud alert or security freeze on credit files can also help prevent new accounts from being opened in your name without your consent. Additionally, exercise caution with unsolicited communications that request personal information.

This information is compiled from the official public filings made with the Indiana Attorney General's office and provides an overview of the reported data breach at Builders FirstSource Inc.

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.
