The incident was unauthorized: Duong later described the activity as illegal and warned readers not to imitate it without explicit permission.
What happened on April 30, 2021?
Duong, writing as WhiteHoodHacker, says the Rickroll affected networked displays across the district—not just one school. The account describes a countdown before displays switched to the video, followed later by a bell-system Rickroll. Futurism reported the incident on October 14, 2021, citing Duong’s post and contemporaneous social media.
Duong described District 214 as six schools with more than 11,000 enrolled students. Those figures are from the participant’s account and are not independently verified here.
How did the student say the prank worked?
Duong’s October 4, 2021 post says an initial scan covered 8,388,606 IP addresses and found exposed network devices, including printers, IP phones, and security cameras. This is the author’s reported scan figure, not an independently verified measurement.

Networked displays
The post identifies Exterity AvediaPlayer receivers, AvediaStream encoders, and AvediaServer management systems as parts of the district’s IPTV setup. Duong says the team used that system to reach networked displays, attributing access more broadly to exposed devices, weak or default credentials, and vulnerabilities in the IPTV products.
Bell system
The account also describes access to the EPIC bell system and says schedules were changed so a Rick Astley song played in place of a bell. Duong says backups and reused or default credentials contributed to access to other bell servers. Futurism repeated the broader claim, but neither report is an independent technical audit.
Rank #2
What happened after the Rickroll?
Duong says the team avoided instructional time, planned the prank before AP exams, and afterward sent district technology staff a 26-page penetration-test report. The post says the team later debriefed staff. Futurism reported that the student and collaborators met with administrators; that account should be understood as reporting based on the post, not as a verified district statement.
Duong’s post includes a direct warning: “This post is for educational purposes only. Do not perform similar activities without explicit permission.” The author also wrote: “With that said, what we did was very illegal, and other administrations may have pressed charges.” The account does not establish that the activity was authorized.

What is—and is not—confirmed?
The detailed technical description and the district-size figures come from Duong’s retrospective account. Futurism is a secondary report that cites that account; it does not provide an independent technical audit. No official district incident statement, audit, court record, or spokesperson quotation is established by these sources. The 2021 incident also does not establish the district’s current security posture, systems, or policies.
