Some of America’s biggest banks are limiting the sharing of information with the Office of the Comptroller of the Currency because they are concerned about potential security risks to their computer networks following a major hack of the regulator’s emails.

JPMorgan Chase & Co. and Bank of New York Mellon Corp. have paused sharing information with the agency electronically, according to people familiar with the matter. The moves follow a major breach of the OCC’s email system where hackers spied on more than 100 accounts over the course of more than a year, Bloomberg reported this month.
