The Department of Financial Services has subpoenaed Equifax over a cybersecurity breach that may have compromised the personal information of 143 million Americans, including 8 million New Yorkers.

At a hearing before the State Senate in Albany Thursday, DFS Superintendent Maria Vullo confirmed reports that the agency, which regulates the banking and insurance industry in New York, subpoenaed the credit-reporting agency seeking more information about the security breach.
