SitusAMC, a major provider of back-end services for leading banks and lenders, has confirmed a SitusAMC data breach that resulted in the compromise of certain client and customer information. The SitusAMC data breach incident, discovered earlier this month, has raised concerns due to the company’s extensive role in mortgage origination, servicing, and compliance within the real-estate financing ecosystem.
According to the company’s disclosure, SitusAMC became aware of the incident on November 12, 2025, and later determined that specific information stored on its systems had been accessed without authorization. While the full scope of the SitusAMC data breach remains under investigation, the company stated that the impacted information includes corporate data associated with clients, such as accounting records and legal agreements, along with certain data belonging to clients’ customers.
SitusAMC emphasized that the incident did not involve encrypting malware and that its operational services continue to run without disruption. External cybersecurity experts and federal law enforcement authorities are assisting in the ongoing investigation.

In its public notice, the company disclosed that upon detecting the incident, immediate steps were taken to investigate, contain, and secure its systems. The firm began working closely with third-party specialists and notified federal law enforcement to ensure a coordinated response.
SitusAMC reiterated that although some information was compromised, all services remain fully operational. No ransomware activity or system encryption was detected, indicating that the attack did not follow the pattern of typical extortion-driven breaches.
