Cornerstone Staffing Solutions, Inc. data breach

Clerk's notes

Cornerstone Staffing Solutions, Inc. filed notice of a cybersecurity incident with Washington state regulators on September 11, 2026. The company, a human resources and workforce management enterprise, reported an unauthorized compromise of its network infrastructure. This report initiates an official monitoring status by authorities.

The breach exposed a range of highly sensitive personal and financial information. The compromised data includes Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Phone Number.
