SitusAMC, an organization that gives back-end providers for high banks and lenders, disclosed on Saturday a data breach it had found earlier this month that impacted buyer information.
As a real-estate (business and residential) financing agency, SitusAMC handles back-office operations in areas like mortgage origination, servicing, and compliance for banks and buyers.
The corporate generates round $1 billion in annual income from 1,500 shoppers, a few of whom are banking giants like Citi, Morgan Stanley, and JPMorgan Chase.
Whereas investigations with the assistance of exterior specialists are ongoing, the corporate underlined that enterprise operations have not been affected and no encrypting malware was deployed on its methods.
SitusAMC acknowledged that information from a few of its shoppers, in addition to their clients’ information, have been compromised on account of the breach, although it did not title any corporations.
“On November 12, 2025, SitusAMC grew to become conscious of an incident that we’ve now decided resulted in sure data from our methods being compromised,” reads the assertion.
“Company information related to sure of our shoppers’ relationship with SitusAMC corresponding to accounting information and authorized agreements has been impacted. Sure information regarding a few of our shoppers’ clients might also have been impacted.” SitusAMC promised to supply additional updates because the investigation progresses.
In a press release to BleepingComputer, the corporate CEO stated that SitusAMC is absolutely operational and shoppers are contacted straight concerning the incident.
“We’re in direct contact with our shoppers about this matter. We stay targeted on analyzing any probably affected information and can present updates on to our shoppers as our investigation progresses” – Michael Franco, SitusAMC CEO
Whereas SitusAMC obtained a security alert associated to the incident on November 12, the corporate decided three days later that it was a breach and began to tell its residential clients on November 16 that it was investigating the assault.
The corporate continued to ship updates to those clients and contacted these impacted by the breach individually as much as November 22, when it notified all its shoppers and confirmed that information was stolen within the assault.
As a result of complexity of operations and information concerned, it’s unclear what number of clients are impacted, and figuring out all of them will take some time.
BleepingComputer has contacted Citi, Morgan Stanley, and JPMorgan Chase to ask if SitusAMC notified them of a data breach and if their shoppers’ information was compromised. A remark was not instantly obtainable from any of the organizations.
