A New 64-bit Linux Rootkit Has Been Discovered

A report on, the Kaspersky Lab Security News Service, warns of a new rootkit for 64-bit Linux.   Researchers who have analyzed its code report that it “appears to be a custom-written tool designed to inject iframes into Web sites and drive traffic to malicious sites for drive-by download attacks.”

“The iFrame injection mechanism is quite interesting:  the malware substitutes the system function tcpsendmsg – which is responsible for building TCP packets – with its own function, so the malicious iFrames are injected into the packets,” Marta Janus, a Kaspersky Lab expert, stated in her report on the rootkit.

The malware attempts to ensure its startup by adding an entry to the /etc/rc.local script:
insmod /lib/modules/2.6.32-5-amd64/kernel/sound/module_init.ko

The good news so far is that on a Debian Squeeze default install (and thus on Ubuntu, which is based on Debian) the /etc/rc.local script ends in the exit 0 command, so the rootkit is never loaded.

Ubuntu 13.04 Daily Builds Now Available

Daily builds of Ubuntu 13.04 – Raring Ringtail – are now available at  This will be the only way to get Raring at present, because the alpha releases have been dropped.

Right now, there is no reason for most of us to upgrade.  There are not many changes from Quantal as yet.  However, the release of daily builds means that the new development cycle has officially kicked into gear.

Raring Ringtail (Ubuntu 13.04) Will Not Have Alpha Releases

According to Nicholas Skaggs, the Ubuntu QA community coordinator for Canonical, the Ubuntu release schedule “has dropped all alphas, and the first beta, resulting in a beta and then final release milestone only. In addition, the freezes have been moved back a few weeks. The end result is the archive will not be frozen till late in the cycle, allowing development and testing to continue unencumbered.”

Thankfully, the flavors (Kubuntu, Edubuntu, etc.) will still be able to keep to the old ways if they choose to do so.

The Raring release schedule now looks like this:

March 28, 2013     Beta Release

April 25, 2013        Final Release

It is to be noted that the schedule for the flavors is different, though tentative:

December 6, 2012  Alpha 1

February 7, 2013    Alpha 2

March 7, 2013        Beta 1

March 28, 2013      Final Beta Release

April 18, 2013         Release Candidate

April 25, 2013         Final Release
