Some hacker group called the "High SMBX Council" has hacked the SMBX forums and removed all announcements include the main SMBX downloads post and wrote fake posts from the admin accounts.
Because not everyone knows about this, I made this topic.
I've made a full backup of our database and site files, just in case.
We have very small chances of being hacked because we are using phpBBex instead of the original phpBB, which has lots of unfixed security holes (one of the old versions of phpBB or original phpBB was used by the SMBX forums).
Here are some IRC logs which have some information about the attack:
