Bad guys broke into the Kernel.org website that is home to the Linux project. They gained root access to a server known as Hera and ultimately compromised “a number of servers in the kernel.org infrastructure” Administrators of the website learned of the problem Sunday and soon discovered a number of bad things were happening. They think that the hackers may have stolen a user’s login credentials to break into the system. The site is making each of its 448 users change their passwords and SSH (Secure Shell) keys.”]
