Minh Duong rickrolls an entire school district

APR 30 2021

Graduating senior Minh Duong and friends spent months mapping Township High School District 214's network in Cook County, Illinois, finding zero-day flaws in its Exterity IPTV system. They simultaneously seized every networked display across all six district high schools to play 'Never Gonna Give You Up' as a fake emergency announcement. Duong submitted a 26-page disclosure report; the district declined to press charges and he presented the work at DEF CON.
