Attorneys General from IL, CT will investigate breach of JPMorgan computer servers

The attorneys general of Illinois and Connecticut will look into a breach of JPMorgan Chase's computer servers.

The office of Illinois Attorney General Lisa Madigan says it will investigate the breach and will work with the office of Connecticut Attorney General George Jepsen. Jepsen's office says it has been in touch with JPMorgan since the breach was first disclosed.

JPMorgan Chase & Co. said Thursday that the breach compromised customer information pertaining to roughly 76 million households and 7 million small businesses. It says there is no evidence that the breach included account numbers, passwords, Social Security numbers or dates of birth. It also noted that it has not seen any unusual customer fraud stemming from the data breach.

JPMorgan Chase is the largest U.S. bank in terms of assets.
