AssetMark Data Breach: Lawsuit Investigation
Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of the AssetMark data breach.
As part of their investigation, they need to hear from individuals who had their information exposed in the incident, including those who received notice of the AssetMark data breach or otherwise believe they are affected.
AssetMark Security Incident: What Happened?
AssetMark, a wealth management platform serving over 10,000 financial advisors and more than 300,000 investor households, has reported a data breach affecting 570,000 people.
A sample notification letter (pictured below) states that AssetMark discovered that an unauthorized actor accessed and downloaded files containing customer information on May 15, 2026, the same day the unauthorized access had occurred. On or around May 18 of the same year, AssetMark determined whose information was contained within the breached files. The AssetMark data breach impacted the company's own systems, rather than those of financial advisors who use AssetMark's platform.
As reported to the Massachusetts Office of Consumer Affairs and Business Regulation and the Vermont Attorney General’s Office, Social Security numbers, financial account information, and government ID numbers were potentially compromised in the incident.
Notice letters were issued to those impacted by the data breach on June 11, 2026.
What You Can Do After the AssetMark Data Breach
If your information was exposed in the AssetMark data breach, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, time spent dealing with the breach, out-of-pocket costs, and more.
A successful case could also force AssetMark to ensure they take proper steps to protect the information they were entrusted with.
