Someone hacked my personal hotspot
Someone hacked my personal hotspot remotely, changed the password and conencted to the internet. Sitting at home I noticed that someone had connected to my phone, when I wen to turn Personal Hotspot off I noticed that my password had been changed to something very weird. I didn't know it was possible to change the password remotely. Is there any way to prevent this from happening or to identify what has connected to my iPhone?
iPhone 4, iOS 6
