A Facebook user awoke to find this phrase on her list of Wall posts: "made $130 today working at home! go to WorkHomeMyself.com to see how you can start also! jdx"
It was posted via the "Mobile Web" and the user doesn't have that functionality set up, so Facebook may be facing a real flaw in their authentication if hackers can slapshot a post into an account, bypassing users' authentication and FB's system set-ups. At present, there is no sign of people with Mobile Web enabled being hacked.
Thanks: WorkHomeMyself.com Can I suggest a real place for finding online work? http://www.someexperiencerequired.com
