[ UPDATE: A reader e-mailed a link to this blog describing a blow-by-blow attack against phpBB.com. ]
One of the most widely used open-source bulletin board system in the world has been attacked by malicious hackers.
According to a brief "maintenance" notice posted on the phpbb.com home page (screenshot below), the attack occurred through a vulnerability in an outdated PHPList installation.
No other details were offered. On the bright side, the phpBB maintainers said no vulnerabilities were found in the phpBB software itself.
The phpBB.com home page and related sites are currently unavailable.
