Cornerstone Staffing Solutions Discloses November 2025 Data Breach

Cornerstone Staffing Solutions, Inc., a human resources and workforce management firm, reported a data security incident that took place on November 6, 2025. The official filing regarding this breach was submitted on September 11, 2026. The specific type of breach has not been detailed in public records.

The compromised information included Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Phone Number. Due to the nature of its business, Cornerstone Staffing Solutions routinely handles a broad range of sensitive personal and financial data for applicants and employees.

Exposure of these data types creates significant risks for affected individuals. The compromise of a Social Security Number and Date of Birth, especially when combined with employment history, can increase the potential for identity theft, the opening of fraudulent credit lines, or the filing of false tax returns. Additionally, Direct Deposit Account Details and Wage and Compensation Information could lead to financial disruption or unauthorized access to bank accounts.

Individuals impacted by this data breach should closely monitor their financial statements and credit reports for any suspicious activity. It is advisable to consider placing a credit freeze with all three major credit bureaus to prevent unauthorized access to new credit. Reviewing and updating passwords for online accounts, particularly those related to banking or employment, is also a recommended security measure.

This information is based on public filings submitted by Cornerstone Staffing Solutions, Inc. to regulatory authorities. The investigation into the full scope and impact of this security incident is noted as ongoing and under monitoring.
