Description

SitusAMC Holdings Corporation provides tech-driven services, staffing, outsourcing, and advisory support to businesses operating in the real estate finance sector. On or about November 12, 2025, the company became aware of unauthorized access to certain systems within its computer network, as noted in a filing with the Maine Attorney General. This initial awareness triggered an internal investigation to determine the scope and nature of the intrusion. The investigation revealed that the unauthorized activity was not isolated to a single moment but extended over a period of several days.

Following the investigation, SitusAMC Holdings determined that an unauthorized third party accessed and acquired data from certain of its systems between November 13 and 21, 2025. The data that may have been involved includes personal information such as names, addresses, dates of birth, driver's license numbers, and financial account information. The company has stated that certain personal information may have been involved, indicating that the breach potentially exposed sensitive data. No further specifics about the volume of records or the exact systems affected were disclosed in the source material.

In response to the breach, Edelson Lechtzin LLP, a national class action law firm, began investigating data privacy claims arising from the incident. The firm is pursuing a class action seeking legal remedies for individuals whose sensitive personal data may have been compromised in the SitusAMC Holdings Corporation breach. Edelson Lechtzin LLP states that it can help affected individuals evaluate their rights and potential claims at no cost. The press release includes a legal notice noting that the communication may be considered attorney advertising in some jurisdictions.
