US banks are scrambling to assess the data theft after hackers breached the fintech company

SitusAMC, which provides technology to more than a thousand commercial and real estate financiers, He confirmed in a statement over the weekend It identified a data breach on November 12.

The company said that unspecified hackers stole company data related to its banking customers’ relationship with SitusAMC, as well as “accounting records and legal agreements” during the cyberattack.

The statement added that the scope and nature of the cyber attack “remains under investigation.” SitusAMC said the incident was “now contained” and its systems were operational.
