As you may also have observed, both the sites JA Voice and JA Job Board, have been defaced 3 times in the last 2 weeks. The reason? The Demo sites running on the same server allows superadmin login access to back-end, which allows to edit layout files (CSS & Templates) in back-end. Therefore, hacker can edit those php files and insert injection code. This made both the sites quite prone to hacking attempts. That's what has been happening for the past 2 weeks.
