When you detect a Wi-Fi device in your network that you absolutely can not identify.
@fribbledom At least you can get a hint from MAC addresses.
Usually, yes. In this case however, it doesn't help me one bit. I thought it may be something suddenly using randomized MACs... but that's not it either.
@fribbledom That's funky.
Time to use whitelisted macs? Not perfect but helps against the casual "hacker".
@fribbledom *runs open wifi*
*sees neighbors forwarding a port to play Minecraft*
*no fucks given*
@fribbledom always makes me skip a heartbeat but then i realize my memory is really poor, kinda like when i put the phone in the other pocket and freak out after i forget about that "revolutionary" change. took me 5 minutes of stressing out to recall, "oh right! the Pi is also connected via wifi."
@fribbledom I've got one unknown wifi device as well.. I've put it on 'pause' instead.
@fribbledom Oh sorry, that was just me, I'll be done in just a minute.
*continues to buy hand bones from amazon*
@fribbledom Jep! That and make a new WPA2 passphrase.
my router allows me to associate MAC to IP of my choice, so I just assign it an IP out of the broadcast, and wait who screams “I cannot connect to internet!!”
@fribbledom at first I would block the MAC and observe the network and your devices. Is one starting to complain?
I've already went down that route. I still couldn't identify it 🤷
@fribbledom could it be a device like a smartwatch that will transfer data over a bluetooth bridge via your phone if wifi fails?
@fribbledom WiFi-signal strength measured from different locations might give a clue. Or a port-scan when the IP is known.
@fribbledom kind of like my colleague answers "whose dev container is this?" is usually "let's shut it down and see who starts cursing"
@fribbledom devices in my network I usually forget about at some point: connected body scale, robot vacuum cleaner, old handheld gaming console that somehow switched itself on and into standby
especially the body scale just connects after a weigh-in, so very infrequently
@fribbledom a guy with too much time on hand programmed the mikrotik to route it to a traffic faker service, which responded with random webpages on tcp80, and weird dns on udp53, with occasional educational webpage inserts. Fun to watch the person wildly reloading and reloading. 😈
@fribbledom Unfortunately I can't find now the article "why my wifi doesn't have a password" where the (famous security guy) author explained how the sharing economy helps the world: only thing he did was bandwidth-limiting freeloaders, and considered the risks smaller than universal benefits. Another point of view.
You never can be enough careful :D
