That's only possible for unencrypted networks/SSIDs, though.

I think that's a different attack, where you could passively sniff wifi traffic from networks without WEP. I meant more just hosting your own hotspot with a popular name, forcing clients to connect to it via disconnect/reconnect attacks, and then you're essentially a tiny MITM ISP that can monitor all their unencrypted traffic

> hosting your own hotspot with a popular name, forcing clients to connect to it via disconnect/reconnect attacks

You can only do that for unencrypted networks or those for which you know the passphrase, though.

In my job I regularly wonder how to get a found phone laptop or notebook back to their owner. The notebook is the easiest. The apple laptop the most stupid. I have the locked laptop i have my iphone you would think, with the closed eco-system, there to be some magic ritual i can perform for the laptop to register on the owners "find my device"???? Or at least let me type a number for them to call? Sometimes, (if i ch…

On my Android phone, the homescreen can have a short message, I changed it to "If found, call {wife's phone number}"

Ha, last winter I lost my phone while snowboarding in the last 300-500m before mountain base. I noticed because I was listening to music with my airpods when I got to the bottom the music had gone silent. Thankfully I had my Apple watch with me, so I immediately got off the board and start running uphill while incessantly spamming the "ping my phone" button. At some point I saw in the watch screen it briefly connecte…

My friend was able to retrieve his phone that had just been pickpocketed out of his backpack that way! "Hey, did you just grab my phone" can take some courage to say to a stranger; "Hey, I can hear my phone ringing in your bag when I press this button!" was much more convincing.

can you not power-off an iphone without unlocking?

I know, great in theory but i havent seen one where it was configured. You can also configure a phone number to call. No one apparently does that.

The solution needs to not require any configuration.

You can call your own phone of course but then i have to keep it charged. If it dies the sim locks.

Yes, like most public hotspot in cafes, schools, libraries, etc where the password is readily shared.

I assumed it would be Bluetooth. Walking/driving around with headphones powered on waiting to pair. WiFi network mirroring is smart.

>wifi network mirroring is smart

Yep, so smart that I used to name my WiFi “McDonald’s Free WiFi” when I lived half a block from McDonald’s. Everyone’s phones would connect but to my goatse’d image network.

I thought devices would start remembering the base station MAC addresses to avoid hijacking but I guess not.. maybe I should start doing this again at my local Home Depot

Edit: just remembered I used to do this on planes too. I would MiTM the AP and people would connect to my WiFi device. Then I would serve an obvious incorrect Bank of America page. No one logged in to it though :(

Direction finding! https://en.wikipedia.org/wiki/Direction_finding

I was looking at that too, but doesn't that usually imply using a directional antenna, rather than just measuring the received signal strength at different locations?

Nope - as everyone who has looked for a buried avalanche beacon knows. As a matter of fact, depending on the number of burials and the searchers, your optimal search technique may be different.

The use of multiple APs with the same SSID is a feature, not a bug. It enables roaming between them.
