La firme de Cupertino a publié une page spéciale Flashback sur son site de support et indique préparer son propre patch. Apple aurait aussi contacté des FAI et des bureaux d'enregistrements pour tenter d'éradiquer le botnet.
Apple sort enfin de son silence. Quelques jours après avoir poussé, sans faire référence à Flashback, une mise à jour de sécurité pour Java sur Mac (voir notre article sur le botnet Flashback), Apple hausse un peu le ton. Et publie sur son site de support une page spécifique au fameux malware qui, d’après Dr.Web, infecterait désormais quelque 655 700 machines. agrandir la photo

Windows has been the target of malware for decades. This has resulted in a more hardened system and a better user awareness.
===> Now, with its growing market share and lower user awareness, it is clear that OS X is becoming more and more attractive to malware authors. <===

Kaspersky Lab -- which is offering the free tool -- counted up to 670,000 infected OS X machines in the botnet last week; today has seen just 227,493 so far, up from 208,301 yesterday.
Over the weekend, Kaspersky saw a major dip in the number of active infected Macs, from a head count on Friday, April 6, of 650,748, to 248,723 on Saturday, and then 237,103 on Sunday.

We all need to use anti-virus, but above all we need to use our common sense...
The Flashback Trojan is a good example of how Mac users are now very much targets of cybercriminal gangs - no longer are these people a ragtag bunch of hackers simply looking to make a name for themselves but well-organised, profit-motivated gangsters - as was the MacDefender (and numerous variants) scareware campaign from last year.
Don't be fooled into thinking that Apple necessarily has your back either - it seriously dropped the ball when it came to the Flashback threat, not issuing an update for Java for weeks after Oracle had made it clear that a vulnerability existed and had fixed the threat for Windows.

Plus d’un demi-million de Mac auraient été infectés, selon Dr. Web, par un logiciel malveillant exploitant une faille Java. Celui-ci, surnommé Flashback, marque-t-il la fin d’une époque ?
Force est de constater qu’Apple n’a pas manqué de travailler à répandre lui-même cette image. Début 2009, l’entreprise présentait même son système d’exploitation comme «un havre de paix.»
Mais cette présentation était à tout le moins discutable. De fait, la division sécurité d’IBM indiquait à la même période que Mac OS X et Mac OS X Server comptaient chacun pour 14,3 % des vulnérabilités dévoilées en 2008.
Pour un environnement hyper sécurisé, on a vu mieux. Par la suite, les démonstrations d’exploits sur Mac OS X n’ont pas manqué.
De quoi donner de l’eau au moulin d’Eric Filiol, spécialiste de la cryptologie, qui rappelait alors que
===> «tous les environnements capables d’exécution [de code] sont potentiellement vulnérables.» <===
Et l’on ne saurait contredire cette affirmation aussi prudente que réaliste.

The new free tool adds to the growing community effort to help affected Mac users remove the malware from their systems. Read this blog post by Topher Kessler on MacFixIt.
This new tool by F-Secure is another advancement by the Mac community against this threat that accompanies not only manual instructions and help from community members, but also swiftly updated definitions for Sophos, ClamXav, VirusBarrier, and other malware scanners for detecting the malware.
On Apple's end, even though the extent of this infection stemmed largely from Apple's delay in issuing a patch for known Java vulnerabilities, the company finally released the patch and has further announced its own Flashback removal tool is in the works.

Nobody is safe, but you can stop the spread before it overtakes your precious.
Mac fans recently got a little taste of what it's like to be a Windows user. That's right, a virus targeting Mac OS X is making the rounds. The latest stats from security companies tracking the virus put the number of infected Macs at well over half a million. That's nowhere near the level of some Windows viruses, but it's widespread enough to be a concern for Mac users.

A look at what the Mac Flashback Trojan could do to infected computers.
So what is the worst it could do?
Although the Trojan is now only conducting click fraud scam by hijacking people’s search engine results inside their web browsers, it has the potential to do greater damage, such as stealing banking or login credential.
If the botnet remains connected to computers, cybercriminals could send new malware to their systems that cause bigger problems.

Apple is developing a tool to "detect and remove" a Trojan that is believed to have infected around 650,000 Macintosh computers.
It said it is working with internet service providers (ISPs) to disrupt the command network being used by hackers to exploit the malware. Trojans are infections that can expose computers to control by hackers.
It is Apple's first statement on the threat. It issued patches to prevent the malware's installation last week.
The two security updates were released ===> eight weeks after Java's developer Oracle issued a fix for other computer systems. <=== Delete the scoop?

“They told the registrar this [domain] is involved in a malicious scheme. Which would be true if we weren’t the ones controlling it and not doing any harm to users,” says Sharov. “This seems to mean that Apple is not considering our work as a help. It’s just annoying them.”

WHAT IS FLASHBACK/FLASHFAKE?
It is a family of malware for Mac OS X. The first versions of this type of threat were detected in September 2011. In March 2012 over 600 000 computers worldwide were infected by Flashback.
The infected computers have been combined in a botnet which enables cybercriminals to install additional malicious modules on them at will.
