The university stated in a FAQ that the notification was issued as soon as possible. "We notified the community as soon as we were confident that notification would not jeopardize our efforts to secure systems and limit damage from the intrusion, potentially making the situation much more difficult to resolve," it stated.
"Higher education is one of the most targeted industries for cyber attacks, and Harvard frequently detects and repels threats," the FAQ noted. "As attacks become more sophisticated, information security teams must quickly adapt and respond to stay one step ahead."
