2011 attack[edit]

On 28 August 2011, developers at realized that there had been a major security breach. Hackers had gained root access to the system and added a trojan to the startup scripts. Developers reinstalled all the servers and investigated the origin of the attack.[1] It is likely, though not yet known, whether this is related to the and website hacks found shortly afterwards.[2][3]

Git, a distributed (and thus open) source management system designed to guarantee the integrity of the source code is used to keep track of changes in the Linux source code. This and the fact that the source code is available to anyone and widely known makes any attempt to tamper with the source code fairly easy to detect and revert if required.[4] is not the primary repository, but rather a distribution point of the kernel sources.

As of November 2011, is completely back up with the exception of a few secondary services.

As of September 2013, the site maintainers still have not published a report of how the breach occurred.[5]
