Well there seems to be a certain exploit going around on FB. it a picure that claims "hack anyone's account by opening their profile and copy pasting this code into the webconsole" where said code uses you logged in credentials to make FB API calls. The version i saw made you like a bunch of pages, follow a bunch of people and tag all of your friends in the comments to that picture. But I wonder if same can be used to change the privacy settings
