Yesterday, I woke my computer up from sleep mode (it had been on all day while I was at work). And my browser was open to an email account that was not mine.
Is it possible that someone hacked my WiFi and then used my computer to visit websites on my computer?
If it is, is there a way to detect when someone had access to my WiFi (were he didn't belong to be) and is there a way to detect if they had access to my computer?
Is this is something that would be relatively easy to do, or would only really experienced hackers be able to do so? Also, would they have to be physically near my house?
