Quatrro Business Support Services, Inc. was the subject of a data breach notification filed with the WA Attorney General. The AG filing was recorded on September 9, 2026.
From the AG filing description
Quatrro Business Support Services, Inc. functions as a critical back-office and business process outsourcing provider, specializing in finance, accounting, human resources, and payroll support for small and medium-sized enterprises, non-profits, and educational institutions. Because the company acts as an outsourced operational arm for numerous client organizations, it centralizes and processes vast quantities of highly confidential records. This includes comprehensive employee files, corporate financial ledgers, vendor banking details, payroll inputs, and tax documentation. Consequently, Quatrro holds an immense repository of sensitive corporate and consumer information, making it a high-value target for malicious actors seeking to exploit interconnected business networks. In 2026, Quatrro Business Support Services reported a significant data security incident to the Washington Attorney General's office. While the precise mechanics of the breach are still under active investigation by cybersecurity experts and legal counsel, incidents involving outsourced business support and payroll processors typically involve sophisticated cyberattacks such as ransomware deployments, unauthorized network intrusions, or credential-stuffing attacks targeting administrative portals. Because modern business support firms maintain expansive digital ecosystems to service multiple external clients simultaneously, a single security perimeter breach can result in widespread exposure across numerous corporate accounts and underlying employee databases. Preliminary indications suggest that the compromised data files contained a devastating array of personally identifiable information (PII) and financial records. For the individuals whose information was housed within Quatrro's systems, the exposure of data such as full names, Social Security numbers, dates of birth, home addresses, banking details, wage data, and tax identification records creates severe, immediate risks. When Social Security numbers and detailed compensation records fall into the unauthorized hands of cybercriminals, victims face heightened vulnerabilities to targeted identity theft, fraudulent tax filings, unauthorized credit applications, and sophisticated financial account takeover schemes that can take years to detect and resolve. As a custodian of sensitive consumer, employee, and corporate data, Quatrro Business Support Services was legally obligated to implement and maintain robust administrative, physical, and technical safeguards to secure its digital environment. Under Washington state data protection laws, as well as overarching federal standards governing data privacy and unfair trade practices, companies handling high-risk personal and financial information must adhere to stringent cybersecurity frameworks. The occurrence of a data breach of this magnitude strongly indicates potential systemic failures in data encryption, access controls, network monitoring, and vendor risk management, raising serious questions about whether the company met its legal duty of care. Receiving a data breach notification letter from Quatrro Business Support Services is a formal acknowledgment that your private information was compromised due to inadequate corporate security measures. Legally, this notice establishes your standing to participate in a class action lawsuit aimed at holding the company accountable for its negligence and securing rightful compensation for your time, distress, and elevated risk of identity theft. Importantly, affected individuals are not required to demonstrate out-of-pocket financial loss to join a class action investigation. Our firm handles these data breach cases on a strict contingency fee basis, meaning you pay no out-of-pocket costs and owe no legal fees unless we successfully recover compensation on your behalf.
Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
You may have been affected by the Quatrro Business Support Services, Inc. data breach if:
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
Applicable State Law
This breach was reported under the Washington My Health MY Data Act, which mandates notification and establishes your right to seek damages.
No. Under Washington My Health MY Data Act and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Quatrro Business Support Services, Inc. does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Quatrro Business Support Services, Inc. during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
