As Linux fans know, there are two kinds of hackers: the good guys who develop free software, such as the Linux kernel, and the bad guys who break into computers.
The bad guys paid the good guys an unwelcome visit earlier this month, breaking 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,” according to a note on the kernel.org website.
Administrators of the website learned of the problem and soon discovered a number of bad things were happening on their servers. Files were modified, a malicious program was added to the server’s startup scripts and some user data was logged.
