The Linux Foundation has issued a warning to Linux.com and Linuxfoundation.org account holders warning of a security breach that may have compromised usernames, passwords, email addresses and "other information".
The 8 September breach is believed to be connected to the hacking of Kernel.org a week earlier. In that breach hackers initially acquired root access to a Kernel.org server and from there gained access to "a number of servers".
Both Linux.com and Linuxfoundation.org are currently down, with a message stating: "Linux Foundation infrastructure including LinuxFoundation.org, Linux.com, and their subdomains are down for maintenance due to a security breach that was discovered on September 8, 2011...
"We are in the process of restoring services in a secure manner as quickly as possible. As with any intrusion and as a matter of caution, you should consider the passwords and SSH keys that you have used on these sites compromised. If you have reused these passwords on other sites, please change them immediately. We are currently auditing all systems and will update this statement when we have more information."
