Sonoma Underground Services Inc, a critical infrastructure and utility contractor based in Indiana, recently announced a data security incident. This breach, formally reported on August 6, 2026, potentially exposed highly sensitive personal information belonging to individuals associated with the company. If you received an official data breach notification letter, your private data may have been compromised.
The types of information reported as exposed include your Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Direct Deposit Account Details, Home Address, Driver's License Number, and Tax Withholding Information. This combination of data significantly increases your risk of identity theft, financial fraud, and other serious forms of personal exploitation.
Such incidents highlight potential failures in a company's obligation to protect sensitive data. Under Indiana state law, companies like Sonoma Underground Services Inc are required to maintain reasonable security measures to safeguard personal information.

If you have been notified, it's important to act proactively. Monitor your financial accounts and credit reports for any suspicious activity. Consider placing a fraud alert or security freeze on your credit. Be wary of unsolicited communications, as scammers often target breach victims who have had their personal information compromised.
