Repéré par des chercheurs de chez Kasperky, le malware SabPub exploite une fois encore une faille de sécurité Java dans Mac OS X via des documents Word piégés.

April 17, 2012 — Network World — It was always thought that as Apple products increased in popularity, so would the target on its back placed by cybercriminals. Always looking to take down the king of the hill, cybercriminals finally got to Apple's Macs last week with a botnet that attacked more than 600,000 machines.
With such an accomplishment, the question is who is really safe from these attacks? The quick answer is no one. Anonymous has proven that.
One expert said recently, "it's the malware lurking in the background from these attacks that is truly scary. "Right now advanced persistent malware is very expensive to do right and is not being produced by very many organizations, but it is getting cheaper, it's going to get modularized and mass produced."

This new minimum-threat malware development for OS X copies Flashback and suggests criminals jump on opportunistic bubbles.
Recently the Flashback malware attacks on OS X gained headlines, not because of the presence of the Trojan, which had been around for some months prior to the increase in attention, but rather because it gained the possibility of installation in a drive-by-download attack that did not require any interaction from the user in order to install.

There are millions of Mac users who are running vulnerable old versions of Java, which are being exploited by the Flashback malware.
===> "50% of all visitors of our Online #FlashbackChecker http://flashbackcheck.com are running a vulnerable version of Java," Aleks Gostev, chief security expert at Kaspersky said on Twitter Wednesday. <===

A new Trojan known as “Sabpab” could hurt Mac users who run Java and Microsoft Word. Security researchers are warning users to make sure their computers
===> have the latest software updates from both Apple and Microsoft, <=== and to use anti-virus software.
In some cases, manual removal of Sabpab may be needed.
Word about Sabpab comes on the heels of another nasty piece of malware, Flashback, that infected up to as many as 600,000 Macs, security experts said, by exploiting a vulnerability in Java software.
Apple last week issued a software-base removal tool for that malware, which can be used by criminals to steal personal information, including passwords.

Découvert par Kaspersky, ce nouveau malware qui cible les Mac exploite une faille de sécurité Java.
Le répit aura été de courte durée. À peine Apple avait-il publié une mise à jour de Java contenant un logiciel de suppression du malware Flashback qu’un nouveau fléau était découvert. Baptisé SabPub, il a été découvert par l’éditeur Kaspersky qui en a repéré deux variantes.
Comme Flashback, SabPub passe par une faille de sécurité de Java au moyen d’un document Word piégé. Le Mac infecté va ensuite se connecter à un site web depuis lequel sont envoyées des commandes. Un pirate peut notamment obtenir des captures d’écran du Mac de la victime.
Cependant, le mode de diffusion de ce malware via des documents Word piégés rend sa propagation moins puissante que celle de Flashback qui a touché 600 000 machines de par le monde.

Because Mac laptops' market share has grown so much, it appears Macs are being targeted more.
I hope the very legitimate sense of security Mac users have long had isn’t turning into a false sense of security.
“For years, Mac users have been able to believe that they are safer than the average computer user and turned their noses up at antivirus software. But as Apple’s market share has grown, so has the threat to Mac users’ security,” the Washington Post reports. Specifically, the Post was referring to a virus called “Flashback” that may have infected “up to 600,000 Macs … mostly in the United States and Canada” which seem now to be part of growing bonnet.” A botnet is a network of “bots” (also called “zombie networks”) that are basically compromised computers – infected computers that are obviously no longer controlled entirely by their owners.
Flashback “should be a wake-up call to those who still think that their Mac is invulnerable to attacks like this,” the Posts added.
The security advice offered in the article sounds a whole lot like what PC owners have been told for very a long time:

A week after the Flashback Trojan began running rampant on Macintosh computers, the malware appears to be in remission.
Scoop.it!
Attackers behind the Flashback and SabPub malware likely reverse-engineered a Java vulnerability patched for Windows almost two
Apple, which normally refuses to comment on any vulnerabilities in its products until after it's released a fix, broke with tradition by last week confirming that it was coding an OS X upgrade to nuke Flashback.
===> According to various security firms, approximately 600,000 Macs had been infected by Flashback, which makes it the largest malware infection to ever hit OS X users. <===
In addition, Kaspersky managed to tie the botnet to six malicious Microsoft Word documents that it's seen in the wild, two of which drop the SabPub vulnerability, and four of which drop the MaControl bot, which appears to be an earlier effort by the same virus writers. One key difference, however, is that MaControl didn't target the Java vulnerability exploited by Flashback and SabPub.
===> Another is that SabPub managed to remain active for about six weeks before anyone detected it. <===
