Equifax was issued a subpoena from New York state’s financial service regulators in regards to the massive data breach the company announced last month, Reuters reported today. The regulators want Equifax to provide more information, which is about right since it seems like Equifax has changed the story several times since the first announcement.

Specifically, Reuters states the subpoena is looking for documents related to the data breach and details on when the company first learned about the hack.
