Although the university doesn't believe at this point that any protected health information or Social Security numbers were compromised, everyone with an Emory University netID/username is being advised to change their account passwords, and to do the same with any other accounts for which they use the same passwords.
"Information security is one of Emory University's highest priorities and we are continually upgrading our systems to defend against cyber attacks," the notification letter states. "Like many institutions, Emory repels millions of attempted attacks on its information systems each day. In recent months, a number of large organizations have reported attacks involving their information systems. Preliminary indications are that the breach at Emory bears many similarities to these incidents."
While the number of potential victims is unknown at this point, SC Magazine notes that the university employed 27,747 people as of September 2012, and the total student enrollment was 14,236 in the fall of 2012.
