We are sorry to report that we have been attacked through a vulnerability in an outdated PHPList installation. phpBB.com and related sites will remain unavailable while we work to recover. No vulnerabilities have been found in the phpBB software itself.
You can download phpBB here: http://www.ohloh.net/p/phpbb
You can get support at the temporary support forums or on IRC: chat.freenode.net #phpbb
– the phpBB team
The good thing is that this is not a phpBB security issue.
Let' hope the phpBB group ...
