Campus Wi-Fi, but make it chaos
Gaining control of every projector and camera on campus
Student says he could map campus tech, and the comments went from cheers to "uh, is that allowed?"
TLDR: A student described building a tool to discover school devices like projectors and cameras through the campus naming system, raising big questions about how visible that equipment really is. Commenters split between cheering the stunt, questioning how it worked, and warning it might cross school policy lines.
A student at the Colorado School of Mines posted a delightfully chaotic tale about realizing every device on campus Wi-Fi could get its own little campus web name, then deciding the only reasonable response was to try to hunt them all down. Instead of taking the easy route, he went full mad scientist: first a slower version in Python, then a faster rebuild in Rust, all in pursuit of identifying projectors, cameras, and other campus gear. In plain English, he was trying to see just how much of the school’s connected hardware could be discovered just from the naming system alone.
But the real fireworks are in the replies. One camp was pure applause — the instant-classic “Banger” set the tone, with others calling it a “very nice article” and praising the write-up like they’d just watched a hacker movie trailer. The other camp hit the brakes hard. One confused commenter basically went, wait, if the network blocks access, how was any of this even reachable? That became the thread’s mini-mystery: was this a terrifying campus-tech exposé, or a really clever digital scavenger hunt with missing steps?
Then came the hall monitor energy. A commenter warned that scanning school devices might not exactly be a gold-star move under campus rules. And in the funniest plot twist, an ex-product manager from Vaddio showed up like a summoned sitcom character to defend his old company’s camera gear: we made people change default passwords, we made a free update tool, we tried! Suddenly the story wasn’t just about one student’s experiment — it was about the internet doing what it does best: cheering, nitpicking, and turning a nerdy campus post into a tiny drama festival.
Key Points
- •The article describes how campus DNS at the Colorado School of Mines assigns a visible subdomain to each device connected to the network.
- •The author evaluated three methods for obtaining hostname-to-IP mappings: DNS zone transfer, certificate/log analysis, and brute-force enumeration.
- •The author chose full brute-force enumeration of subdomains rather than using a hostname dictionary, despite the exponential search space of 37^n.
- •An initial asynchronous Python implementation worked but was limited by slow permutation generation and was only practical for short hostnames.
- •The tool was rewritten in Rust, where the author optimized candidate generation using integer incrementation and base-36 conversion, then parallelized the search across multiple processes.
