Overview

• Over two million students, applicants and employees had identification numbers, citizenship status, admissions decisions and other personal data stolen in the June 24 hack.
• The attack triggered campus-wide outages that locked users out of email, coursework and video-conference platforms for several hours.
• Public monitors across the Manhattan campus briefly displayed images of President Donald Trump during the outage, though Columbia has not linked the display to the data theft.
• By June 29, most IT systems were restored, and officials report no further suspicious activity on the network since the breach.
• Officials say they will notify all individuals whose information was compromised once the forensics review is complete.
