Someone hacked my account and levelled me up...

So, where do I begin.

I log onto my origin, it says someone is online, I'm thinking okay that's probably just my sister. I ask my sister if she is using origin, she says no so I'm thinking it's just a bug, I kick the person off and open battle field 4.

I get into a game and do you know when you have something new unlocked and then if you hover over the thing it removes the notification, yeah there was one of those and I always hover over unlocks. They also changed loads of my load outs.

About three weeks go by of me not playing I open up bf4 (no kicking anyone off) and I get into a game and I play for like an hour, I got promoted. I check my rank and it says 88, I think wait a minute I'm not rank 88, am I? After thinking for a bit I remember that I entered my level into the app bf4 Intel, so I check it out and it said I was rank 55 (it doesn't auto update) and I knew for sure someone had been on here. I hovered over the unlocks too lol.

I change my password, now my account is safe again. I don't know why he didn't change my password, he definitely could have but I guess he just wanted to play a ton of bf4.

Have a great day guys and make sure no one is on your account lol.
