Alors que pendant longtemps, la majeure partie des spécialistes n’imaginait pas que les virus en tous genres puissent arriver sur Mac, cela est désormais une réalité.
Les PC ne sont plus l’unique cible des pirates informatiques et des hackers.
Face au nombre croissant d’attaques qui subsiste sur internet, il est très important de se munir d’un antivirus pour Mac comme d’un antivirus pour PC. Concernant le système d’exploitation créé par Steve Jobs, il est visé par les cybercriminels car il y a de plus en plus de possesseurs de Mac, ce qui affute leur volonté de perturber de nouveaux utilisateurs.

Mac users are now prime targets as an APT attempts to execute on a Mac OS.
This development in targeted attacks just shows that the groups behind campaigns such as this one are taking into consideration changes in the computing landscape, such as the increase in the number of Mac users.
===> This adjustment to affect Macs also shows that they are refining their scope, and are really customizing their tools to suit their targets. <===
More on this as we are continuously investigating this. Stay tuned.

I’m guessing that the myth of OS X invulnerability to malware is pretty much busted by now: at any rate, there has been wave after wave of OS X-related malware reports in the past week or two.
Sophos were the latest big name to weigh in on the OSX/Imuler malware that DrWeb, Intego, ESET and your humble scribe have already commented on, though Sophos calls it Imuler-B and both Intego and ESET call it Imuler.C.
The Java attack has also been linked to bot-generated Twitter spam targeting Tibetan activist conversations by including hashtags like “#Tibet” and “#freetibet”, presumably in order to drown out political dissent.

A hole in Apple's mobile Safari can be exploited to display a different URL in the address field than the Web site being viewed in the browser.
Users of iOS 5 users, beware a security flaw in Safari that can be used to trick you into visiting potentially malicious Web sites.

The Mac Imuler Trojan uses images of FHM supermodel Irina Shayk to do its dirty work.
Somehow I doubt that Mac users are any smarter than their Windows cousins when it comes to resisting temptation.
We're all human, after all. And there is a (probably significant) proportion of the population which isn't adverse to searching the web for nude pictures of supermodels.
Of course, the bad guys who spread malware know about human weakness all too well - and exploit it regularly to trick computer users into clicking on files and installing malicious code that exposes them to risks.
===> By default, Mac OS X doesn't display file extensions. Which means, that Mac users might be duped into believing that the file they are about to click on is a JPG image, rather than an application. <===

Keep in mind that this list is skewed toward professionals and technophiles who are using the iPad on a daily basis, but I also realize that these folks tend to use tablets like the iPad for non-work stuff as well, like reading the news in the morning during breakfast or a little entertainment on the plane during a business flight.

On Monday, I provided steps on how to avoid your Mac being compromised by the Flashback trojan. Today I will provide information on how to locate a Flashback infection.
To better understand the steps below, it is better to also know a bit about Flashback. It's an OS X malware family that modifies the content displayed by web browsers. To achieve this, it interposes functions used by the Mac's browsers.
The hijacked functions vary between variants but generally include CFReadStreamRead and CFWriteStreamWrite: read more...

Security researchers from Sophos, have intercepted a currently circulating Mac OS X malware variant of the OSX/Imuler trojan horse.
Upon execution the malware will delete the original infection file and only leave an image file of Irina Shayk. It will also open a backdoor on the infected host, transferring private information from the infected host to a remote Web server.
