Comment on After seeing Wi-Fi network named “STINKY,” Navy found hidden Starlink dish on US warship

Sailors on the ship then began finding the STINKY network and asking questions about it.
Oh, c’mon. it is trivial to make an SSID “hidden” for any networking tech that you have administrative control over. That way, only those “in the know” will know the SSID name to type in, in order to access said wireless network. It would not be “discoverable” by standard wireless-connectivity gear such as the default wifi interface in mobile phones.

Hidden WiFi networks are not actually hidden in the literal sense. They still broadcast beacons that your wifi chip will see as basically “hidden network beacon lives here”. Your network connect interface just decides not to show you a list with a bunch of useless “(hidden)” entries you can’t do anything with.
Also, when a new client wants to connect to the hidden network, the first thing it does is broadcast an unencrypted message saying “HEY, I’M LOOKING FOR [hidden network name]” so it’s completely trivial to unveil the name of hidden networks given enough time.

I think it’d be more for obfuscation than completely hiding it. As long as there are other hidden networks on the ship you just name it something generic that blends in. I mean this whole thing is a really stupid idea, but naming it something like “COM.NAB_ISO:4133” would draw less attention.

It’s absolutely mind-boggling that the existing WiFi infrastructure on the military ship didn’t trigger any alarms. This is the kind of thing that you can get from “pro-Sumer” grade hardware like Ubiquiti, let alone corporate-grade or military-grade stuff. The feature is called “Rogue Access Point Detection” and it’s built into literally every WiFi solution on the market. Like, your local library is analyzing this stuff it’s that basic.

Yup, I did some on-campus IT work while I was in college and it was super trivial to detect when people would have their own networks on the dorms

That’s why I put that term in quotes, and was specific about default networking interfaces. I didn’t go into detail because that confuses a lot of people.

Yea, that was a good editorial choice on your part. I did pick up on your scare quotes, I just thought it would be good to tack on the additional info “below the fold” because it’s just baffling to me that 20 years later the majority of people still think they’re hackerman when they make WiFi “hidden”.

Client devices can also do this all the time even when not in range, which basically broadcasts they’re looking for that network everywhere they go. That’s just asking for someone to setup a rogue access point.
