Cornerstone Staffing Solutions Inc data breach

Clerk's notes

On September 11, 2026, Cornerstone Staffing Solutions Inc formally reported a data security incident to Indiana authorities. This filing indicates that an unauthorized compromise of their network environment occurred around November 6, 2025, affecting individuals whose sensitive information was managed by the human resources and workforce management provider. The investigation into this event is currently listed as monitoring.

The reported breach exposed several categories of highly personal and financial data. This includes individuals' Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Home Address, Phone Number, and Employment History Records. This comprehensive exposure involves core identifiers and financial specifics typically entrusted to staffing agencies.

The compromise of such extensive data creates significant risks for affected individuals. Exposure of Social Security Numbers, Date of Birth, and Full Name can facilitate identity theft, while Direct Deposit Account Details, Wage and Compensation Information, and Tax Return Information present avenues for financial fraud, including unauthorized account access or fraudulent tax filings. Employment History Records and contact details like Home Address and Phone Number further contribute to potential misuse of personal information.

A data breach of this nature suggests potential vulnerabilities in their data protection protocols.
