Sonoma Underground Services Inc, a utility and infrastructure contractor, has formally reported a data breach to the Indiana Attorney General's office. The incident, which occurred on December 10, 2025, involved unauthorized access to sensitive information maintained by the company, with the report filed on August 6, 2026. While the exact cause is under investigation, such breaches often stem from sophisticated cyberattacks.
The exposed information includes a concentrated array of highly sensitive personal data. Specifically, the breach compromised individuals' 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 types creates a significant risk for identity theft, financial fraud, and other related harms.
The compromise of Social Security Numbers, Dates of Birth, and Driver's License Numbers can make affected individuals vulnerable to the creation of synthetic identities or fraudulent accounts. Additionally, the exposure of Direct Deposit Account Details, Wage and Compensation Information, and Tax Withholding Information directly threatens personal finances and could lead to unauthorized access to bank accounts or fraudulent tax filings.
Companies like Sonoma Underground Services Inc are legally obligated under state data protection statutes, including the Indiana Disclosure of Security Breach Law, to protect the sensitive personal information they collect and store. The occurrence of a data breach suggests that the company's security measures may have been insufficient to meet this legal duty of care, potentially leaving individuals exposed due to inadequate administrative, physical, or technical safeguards.
If you have received a data breach notification letter from Sonoma Underground Services Inc, it confirms that your personal information was compromised. You do not need to prove actual financial loss to explore your options; the increased risk of future identity theft and the time and expense required for mitigation are often sufficient grounds. We are currently monitoring this situation and investigating potential class action claims on behalf of all affected individuals.
