Why learn to hack wireless signals in a homelab? (lemmy.world)

Hi, I realise that this might not be a question for this community; that said, this community is fairly big so I'm sure plenty of people here are already doing this.

I have been interested in hacking wireless infrastructure for a while now, but I'm struggling to find motivation in my day-to-day life to actually embark on said journey. Frankly speaking, I don't see a point to do so in a modern homelab. If someone is using WPA3, no unsecured wireless connections like Bluetooth, and uses strong passwords, how would someone realistically hack them without a good amount of time/resources?

One avenue that I came up with, related to wireless hacking, is with IOT. I do not know much about the security of various wireless protocols like Zigbee, or if one can somehow decrypt MQTT messages (they are sent using TLS, yes?) or anything of the sort. Other than this, I'm really struggling to see a practical point in pursuing action in this field (other than the basics like upgrading to the most secure protocol and maintaining digital hygiene) unless one is interested in wireless hacking from pure interest (without any need for motivation stemming from problems in their lab).

Thanks!

It's fun to learn a bit more about how wifi and encryption works by cracking it using something like aircrack-ng. There's not really any other practical use unless you have bad intent or are planning on entering the security field.

I would agree that curiosity is the biggest driver here. A while back I played around with kali and aircrack-ng and was eventually able to crack one of my neighbors WiFi (big city - lots of signals). Even entered the router which was set up with the “standard credentials” of its type. But in general it’s very unlikely that you will successfully crack any WPA2 Wi-Fi signal. If you want to crack a specific signal it gets even trickier…

FWIW that's illegal and is considered hacking in the US and can result in jail time. You should only do this on equipment you own. Not saying you did anything particularly nefarious or that the chance of getting caught is high but just FYI.
