Case notes

Cornerstone Staffing Solutions, Inc., a human resources and workforce management provider, has reported a data breach to Oregon state authorities on September 11, 2026. The incident, which occurred on November 6, 2025, involved the exposure of various sensitive personal records.

The reported data types exposed in this breach include Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Telephone Number.

Exposure of these data types carries significant risks for affected individuals. A Social Security Number combined with a Date of Birth and Full Name can be used for identity theft, leading to fraudulent accounts, loans, or tax filings. Direct Deposit Account Details and Wage and Compensation Information could enable financial fraud, while Mailing Addresses and Telephone Numbers may be used for targeted scams.

Individuals who receive a breach notification from Cornerstone Staffing Solutions, Inc. should take immediate steps to protect their information. It is advisable to review financial statements and credit reports for any suspicious activity. Consider placing a fraud alert or freezing your credit with the major credit bureaus. Remain vigilant against unsolicited communications, particularly those asking for personal details.

Regularly checking your credit report helps identify unauthorized accounts or transactions. By taking these protective measures, you can reduce the potential impact of the exposed data.
