FlashBack : le cheval de Troie qui a touché 600.000 Mac

FlashBack : le cheval de Troie qui a touché 600.000 Mac | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
Un éditeur de sécurité russe estime à 600 000 le nombre de machines d’Apple infectées par le Trojan.

 

MacOS reste la plate-forme la plus hermétique aux malwares mais son succès dans le monde suscite de plus en plus d'intérêt de la part des pirates. La preuve : l'essor de Flashback, un Cheval de Troie qui aurait tendance à vite se propager sur la planète.

 

Le malware qui profite de deux failles de sécurité du plugin Java s’est propagé principalement en Amérique du Nord (76,4%), au Royaume-Uni (12,8%) et en Australie (6,1%). La France quant à elle représenterait 0,6% des ordinateurs infectés par le cheval de Troie. C’est la compagnie d’anti-virus Russe DrWeb qui a mené l’enquête.

The scariest thing about the Flashback trojan: I have no idea how to fight it

The scariest thing about the Flashback trojan: I have no idea how to fight it | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
The recent reemergence of the Flashback OSX trojan has shown a lot of things, but none more clearly than this: I have no clue how to counter virus and...

 

I remember telling friends and supervisors multiple times that if a major Mac virus or trojan were to emerge, I would be at a complete loss as to how to fight it. This is probably still true, as the emergence of the Flashback trojan has shown most clearly.

 

The most recent version of Flashback targets a unpatched Java vulnerability in OSX, one that Oracle fixed months ago but Apple never got around to relaying. Now, I’m still not entirely sure what Flashback does, but I was pretty completely clueless on how I could fight it. This is the bitter reality of being a Mac owner in 2012. I have very little idea of how to keep my machine safe.

 

And I imagine many other Mac owners feel the same way.

 

If the half million Flashback-infected Macs are any indication, ===> Mac owners are all going to need a crash course in computer safety. And fast. <===

600,000 Macs compromised by Flashback botnet

600,000 Macs compromised by Flashback botnet | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
Apple users will be suffering a crisis of faith, as it was revealed its faith-based security system failed to prevent over 600,000 Macs around the world from being compromised by the Flashback Trojan.

 

Apple has now released a patch that should squash the vulnerability. Whether or not Apple users will rush to protect their machines is another matter. Earlier this week, Sophos' Graham Cluley urged users to be vigilant. There had been a "flood of Mac malware activity" against users in mid-2011, with a steady stream since.


Users were encouraged to consider that many cyber attacks are not specifically technical, but rely on social engineering and human folly.


Apple fans would be "foolhardy" not to protect their Macs with anti-virus software and to keep it updated, Cluley said.

 

===> "Especially as there are free Mac anti-virus options available, you really have nothing to lose". <===

 

                       ===> NOBODY IS PERFECT!!! <===

New Mac malware epidemic exploits weaknesses in Apple ecosystem

New Mac malware epidemic exploits weaknesses in Apple ecosystem | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
The nightmare scenario for Mac owners is here. At least 600,000 Macs worldwide have been infected, silently, by the Flashback virus.

 

What makes this outbreak especially chilling is that the owners of infected Macs didn’t have to fall for social engineering, give away their administrative password, or do something stupid.

 

All they had to do was visit a web page using a Mac that had a current version of Java installed.

 

Macs are not immune. For years Apple owners have been told that Macs don’t get viruses, but we know that’s not true.

 

And Apple’s casual approach to security updates makes them arguably more vulnerable to this sort of attack than other platforms.

Le botnet Flashback met à mal le sentiment d’invulnérabilité sur Mac

Le botnet Flashback met à mal le sentiment d’invulnérabilité sur Mac | Apple, Mac, iOS4, iPad, iPhone and (in)security... | Scoop.it
C'est du jamais vu : une entreprise de sécurité russe a découvert un réseau de 600 000 Mac zombies, infectés à cause d'une vulnérabilité de Java.

 

On peut même ici parler d’erreur, car la faille qu’il exploite est loin d’être inconnue. Depuis le mois de février, Oracle propose une mise à jour critique pour la corriger.

 

Les utilisateurs de Windows qui utilisent Java l’ont par exemple obtenue grâce à l’outil de mise à jour de Java.

 

Mais sur Mac, c’est Apple qui centralise ces mises à jour de sécurité et qui les distribue par l'intermédiaire d'un outil intégré à Mac OS X.

 

Or la marque à la pomme n’avait pas publié ce correctif !

 

Il a été poussé avant-hier, mardi 3 avril 2012, comme le montre cet avis de sécurité.

 

===> Un peu tard, quand on sait que 600 000 machines sont infectées par ce virus. <===
