CNN reported that SitusAMC notified a number of major institutions, including JPMorgan Chase and Citi, that their data had been affected by the cyberattack. It remains unclear how many consumers or how much data might have been affected. The FBI has said it was aware of the breach but had not identified any resulting issues with banking services.
