Hewitt Associates LLC

On July 7, 2016, Hewitt Associates LLC suffered a data breach that exposed sensitive personal information of 55 individuals out of 2,892 notified. The compromised data included names, Social Security numbers, contact details, dates of birth, and employment-related records. The breach was formally reported to the California Office of the Attorney General on November 29, 2016, indicating a delayed disclosure. While the exact cause of the breach was not specified, the exposure of highly sensitive personally identifiable information (PII)—particularly Social Security numbers—poses significant risks, including identity theft, financial fraud, and long-term reputational harm for affected individuals. The incident highlights vulnerabilities in the company’s data protection measures, especially concerning employee and client data security. Though the breach affected a relatively small subset of the notified group, the nature of the exposed data elevates its severity due to the potential for malicious exploitation by threat actors.
