This exploit succeeds only by attacking the weakest link: the gullible human operator. The OS itself cannot be directly penetrated by this exploit.
You said it much more succinctly, and you are right.
I get so tired of these threads, where people who do not understand Apple’s OS jumping up and down with glee whenever they read about some FUD exploit.
I understand that some have a preference for other operating system, and respect their choices. Why don’t we get the same back?
Not all of us have the time to manage/twink/troubleshoot our computers, and if we do not work in an environment that has an IT department to keep us productive, we look for a system that will just let us get the job done, without down-time.
Even this doesn't work that well. . . the OS will protect the stupid by warning if someone tries to download something onto OS X that could try to get it onty iOS. . . but to get it iOS directly requires jailbreaking the device. That really requires some complicated acts on the part of the user. . . not just a mere download and install.
