DataBreachCaseFile.com has logged this incident based on a WA regulatory filing. Mariner Wealth Advisors, LLC was responsible for safeguarding the personal data of its customers and employees. Mariner Wealth Advisors, LLC experienced a data security incident affecting an undisclosed number of individuals, exposing financial account information and payment data. The precise date the breach occurred was not disclosed in the filing; the date below reflects when Mariner Wealth Advisors, LLC notified the WA Attorney General. The filing summarized the incident as follows: "Mariner Wealth Advisors, LLC is a prominent, nationally recognized wealth management and financial advisory firm dedicated to helping individuals, families, and businesses plan for their financial futures. Because of the sophisticated nature of their services—which include comprehensive wealth planning, retirement income strategies, investment management, tax planning, and estate coordination—the firm routinely collects, analyzes, and maintains vast quantities of deeply sensitive financial and personal data. Clients entrust Mariner with their complete financial lives, requiring the firm to securely store confidential records that make its digital infrastructure an attractive target for malicious actors seeking lucrative financial information. In 2026, Mariner Wealth Advisors, LLC formally reported a significant security incident to the Washington Attorney General, alerting regulators and consumers to an unauthorized compromise of its network systems. Within the financial services sector, incidents of this magnitude typically involve sophisticated cyberattacks such as unauthorized database access, credential harvesting, or exploitation of vulnerabilities within third-party vendor applications. Financial institutions are prime targets for organized cybercrime syndicates aiming to siphon proprietary data, deploy ransomware, or exfiltrate high-value customer records for illicit monetization on the dark web. The exposure resulting from a breach at a wealth management firm like Mariner involves exceptionally sensitive categories of information that create immediate and severe risks for affected individuals. Compromised data typically includes full names, Social Security numbers, dates of birth, financial account numbers, routing numbers, and detailed investment or transaction histories. Unlike basic retail data, the exposure of comprehensive financial profiles leaves victims acutely vulnerable to sophisticated financial account takeovers, unauthorized wire transfers, fraudulent loan applications, and ongoing, targeted tax fraud that can take years to fully identify and remediate. Under federal and state law, financial institutions such as Mariner Wealth Advisors, LLC are bound by stringent legal and regulatory obligations to safeguard client data. Specifically, the Gramm-Leach-Bliley Act (GLBA) and state consumer protection statutes require financial organizations to maintain robust administrative, technical, and physical safeguards to protect nonpublic personal information. The occurrence of a data breach of this scale strongly indicates a failure to maintain adequate security controls, encryption protocols, and continuous monitoring systems, representing a potential breach of these foundational statutory and common-law duties of care. For clients and consumers who receive a formal data breach notification letter from Mariner Wealth Advisors, LLC, the notice serves as an official admission that their private financial information was compromised due to corporate inadequate security. Legally, receiving this letter establishes the necessary standing to participate in a class action lawsuit aimed at holding the company accountable for failing to protect its clients. Individuals affected by this incident do not need to prove that financial fraud has already occurred to seek legal recourse, and our firm evaluates and pursues these cases on a strict contingency fee basis, meaning there is never any out-of-pocket cost unless a recovery is secured." Setting up transaction alerts and reviewing recent bank and card statements is the fastest way to catch unauthorized activity. The public filing remains available for affected individuals who want to review their options.

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.
Under the Washington My Health MY Data Act, you may have a legal claim if:
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.
Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.
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 Mariner Wealth Advisors, LLC 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 Mariner Wealth Advisors, LLC during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
Join the class action and seek compensation for your exposure.
