Google Home Mini - how did you manage to hack the device?

Question

Burglary protection

Hello.

Last night, my Google Home Mini speaker started talking - an unknown voice in English began to talk about the need to monitor information security :) Then some music started playing. As far as I understood, the voice was also a recording, and not a "live connection".

It is clear that the column was hacked, I began to search the network for what kind of hacking, but I did not find anything specific. This happened to different users, but there the cracker personally communicated, plus some device / network settings changed.

I read that, most likely, the WiFi in the house was hacked by someone. But the problem is that I live in Spain, and the voice broadcast in English, so it is unlikely that this is some kind of local hacker. Plus, I don't give anyone the password for my network.

In general, the question is - what was it and how to deal with it?

Answer 1

WPA2+WPA encryption, password like this GS83FF88GLK5, it has 14 characters. The router is provider, it does not understand any characters for the password, except for numbers and letters.
Now I looked - I had DMZ and Port Mapping active - once upon a time I played around with one thing and never turned it off. Now turned off.

Answer 2

local hacker, voice recorded or translated
You (most likely) broke the wifi
to defend yourself - set a normal password with wpa2 encryption - from 10 characters
right now what encryption? what password? (you can write, we are far away from you) ))

Answer 3

connect Amazon and Alice - they will fuck her up
