Sorry i didn't know where to post this.
I already changed all my passwords, but a friend told me that he saw in a forum that a self-called U3 Team developed a code, with that code they register in your forums and obtain acces to your admin acounts, he also told me that in that forum were a code that you had to change in order to prevent hacking to your forums, is that true?
ADDED: I didn“t change my ubb code with what was in that forum because i hadn't my ubb forum in that time
