  • The company stated no encrypting malware was involved, indicating a focus on potential data access rather than service disruption.
  • The New York Times reported that client data for JPMorgan Chase, Citi and Morgan Stanley may have been accessed, though SitusAMC did not name affected clients.
  • CEO Michael Franco said law enforcement was notified, and the FBI said it is working with affected organizations and sees no operational impact to banking services.
