I would send emails to abuse@neiu.edu and phishing@neiu.edu. In addition, you could perform a whois lookup on the domain to get the Technical Contact: https://who.is/whois/neiu.edu and send an email to admin@neiu.edu

If you wanted to take it another step forward, here are the folks you could probably contact: https://ssb.neiu.edu/mercury_neiuprod/GZKDIRL.P_DISPLAY_DEPT...

Hope this helps.
