The New York firm, which counts 1,500 clients for services including residential and commercial mortgage origination and payment collection, said it uncovered the incident on Nov. 12. The firm said it confirmed that corporate data such as accounting records and legal agreements were affected by the incident – it didn’t say whether hackers stole or merely viewed that data – and that certain data relating to some of our clients’ customers may also have been impacted. The company did say that “no encrypting malware was involved” and that “the incident is now contained.”
As a mortgage processor, the SitusAMC handles sensitive information such as Social Security numbers, passport details and employment records. The New York Times on Saturday reported the incident exposed data related to residential loan mortgages.
The company did not immediately respond to a request seeking clarification to whether personal data has been impacted. The New York Times reported that SitusAMC customers impacted in the breach include JP Morgan Chase, Citi and Morgan Stanley. A JPMorgan Chase spokesperson told the publication the incident did not result in direct compromise of the banking systems.
A Citi spokesperson refused to comment, and Morgan Stanley did not immediately respond to requests for comment. In a statement to The New York Times, FBI Director Kash Patel said his agency is investigating the incident.
SitusAMC said it notified its impacted customers.
The latest incident marks the growing case of breaches tied to third-party compromises, which accounted nearly 30% of incidents in 2025, according to the latest annual Verizon Data Breach investigations report. Self-regulatory organization Financial Industry Regulatory Authority in October 2024 warned it was observing a spike in cyberattacks and outages at third-party providers used by member firms. Reliance on third parties, it said, “aggravates the risk to member firms.”
