When we have Wi-Fi router and and somebody is connected to it, they can access its settings by visiting
192.168.1.1 or some other address. If password for router access is weak then router can be taken over.
What about tethered Wi-Fi hot-spot. I am using an Android cellphone and I have many notorious friends. Is it possible for a hacker to obtain sensitive information (or get root access) if they are connected to my tethered Wi-Fi hot-spot?
