¿Por qué Apple recomienda usar antivirus? On the Mac platform this issue has always been more anecdotal than worrying. But it seems that the growing number of Mac OS X users is starting to be a focus of attention for crackers.
One of the latest known threats to the platform employs a method already known in Microsoft environments. Insert the malicious code into a file with a file extension known as .PDF, .XLS or .DOC. The file that appears to be circulating inserts malicious code into a .PDF document that after execution installs malware named Imuler.A . Which a priori leaves a “back door” open in order to communicate with a remote server.
According to F-Secure, the ability of Mac OS X to store the icon inside a container makes this type of threat even more dangerous. A possible solution may be to enable the option in Finder preferences to show file name extensions. But as I always say, whatever the operating system, the best antivirus and protection method is the user himself and his way of acting (downloading files from safe and reliable sites).
Do you worry about these issues in Mac OS X? Are they really a threat or an attempt by some to place their software? Is the excessive confidence we have in the system detrimental?
Update: Andropov indicates in the comments how to check and remove the threat.
