No classified systems are believed to have been affected, according to a statement from Justice Department spokesman Marc Raimondi. It did not identify to whom who the potentially compromised email accounts may belong.

It was not immediately clear whether the intrusion at the Justice Department and other agencies included access to data other than email because Microsoft’s Office 365 includes multiple document-sharing and collaborative components.
