The site don't appear to be storing any sensitive information of their student. However, such an attack can still impact an institute's image.SaHoo have just uploaded his deface page on the university server directory, nothing harm has been done to the server or any students information's.
At the mean time, the deface page on the Stanford University site is still there, but the deface page on the MIT sub-domain has been removed. You can check the attacked sites with the mirror below.
