Somebody just signed into my network and Google account. It's from a Mac device, but I don't have any Apple devices.
Also he logged into Google from my IP address. After that, I got a notification on my phone that somebody signed in my account.
I also used a tool called wi-fi inspector from Avast and found some Cisco device. I don't know if it's a VPN or something. I got his MAC address. And tips what to do?
