The California Attorney General record also lists January 13, 2026; accessible sources do not explain the precise role of that additional date in the incident.\u003C\u002Fp>\u003Cp>Mariner said it isolated and secured the affected accounts, investigated with third-party experts, and communicated with law enforcement and regulators. The firm reported finding no evidence that the personal information was misused.\u003C\u002Fp>\u003Ch2>Affected data and boundaries\u003C\u002Fh2>\u003Cp>The exposed fields were not identical for every person. Public notices identify names, dates of birth, Social Security numbers, account numbers, and driver's license information as possible fields; an individual notice specifies which fields applied to its recipient.\u003C\u002Fp>\u003Cp>The company said financial accounts, investment accounts, and client account systems were held on separate systems and were not affected. The presence of account numbers in downloaded files does not establish access to those systems or unauthorized movement of funds.\u003C\u002Fp>\u003Ch2>Identity-theft precautions\u003C\u002Fh2>\u003Cp>People whose Social Security number or date of birth was affected can consider placing a free credit freeze with the three major credit bureaus. Credit reports should be checked for unfamiliar accounts, inquiries, and address changes.\u003C\u002Fp>\u003Cp>Anyone whose driver's license information was involved can ask their state motor-vehicle agency for identity-misuse guidance. Suspicious credit or tax activity should be reported promptly to the appropriate institution.\u003C\u002Fp>\u003Ch2>Account and phishing security\u003C\u002Fh2>\u003Cp>Although financial account systems were reported as unaffected, exposed identity details can make fraudulent advisory, investment, or account-verification messages more convincing. Unexpected transfer or profile-update requests should be confirmed through a separate channel.\u003C\u002Fp>\u003Cp>Find contact information through Mariner's official domain instead of following a link in an unexpected notice. Do not provide a password, full Social Security number, or one-time code in response to an unsolicited call or message.\u003C\u002Fp>\u003Ch2>Record scope\u003C\u002Fh2>\u003Cp>The 8,995 figure is the incident total reported in the Maine regulator filing; the 17 Maine residents are a state subset of that total. The state count is not used as a separate total, and no data field is generalized to every affected person.\u003C\u002Fp>\u003Cp>The event was described as limited to specific cloud applications used by three employees. Public sources do not say whether the initial access involved phishing, password reuse, or another technique, so the attack vector remains unconfirmed.\u003C\u002Fp>\u003Ch2>How to interpret a result\u003C\u002Fh2>\u003Cp>\u003Cstrong>A positive match\u003C\u002Fstrong> means the queried email address appears in a dataset associated with this incident; it does not prove that every listed data class belongs to that person. The individual notification letter provides the most specific scope.\u003C\u002Fp>\u003Cp>A negative result does not prove that a person was unaffected. Anyone who received an official notice should follow its instructions regardless of the search result and continue monitoring identity and credit records.\u003C\u002Fp>","","Mariner Wealth Advisors Data Breach (9 Thousand People Affected)","Mariner Wealth Advisors' cloud breach affected 8,995 people.
