Quatrro Business Support Services, a provider of outsourced finance and HR support, reported a significant data security incident to the Washington Attorney General in September 2026. This breach exposed a wide range of sensitive personal and financial data for individuals whose information was managed by Quatrro. Those who received a notification letter should be aware of the heightened risks of identity theft and financial fraud.
Quatrro Business Support Services, Inc., which offers critical back-office functions including payroll and HR support, formally reported a data security incident to the Washington Attorney General's office on September 9, 2026. Given Quatrro's role in managing extensive client data, this event potentially impacts numerous individuals whose information was processed by the company.
The compromised data files reportedly contained highly sensitive information. This includes individuals' Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Mailing Address, and Email Address. The exposure of such detailed personal and financial records creates a substantial risk of identity theft, fraudulent tax filings, and other financial crimes.
As a custodian of private information, Quatrro Business Support Services had a legal obligation to implement robust security measures to protect the data entrusted to it. Under Washington state data protection laws, companies handling sensitive personal information must adhere to stringent cybersecurity standards. A data breach of this nature raises serious questions about whether Quatrro met its duty of care in safeguarding consumer and employee data.
