Apple Acknowledges MacDefender

Trailrunner7 writes with an article in threatpost "Apple is planning to release an update specifically designed to protect users against the MacDefender malware that has been circulating for the last couple of weeks. The update for Mac OS X will automatically find and remove the malware on an infected machine and also will warn users if another infection attempt is detected.

Unless you do that, it won't go anywhere. You can always just cancel the install and drop it in the trash. Pretty convincing hack though except that it crashes most of the time.

If you have not unchecked the "Open safe files" box in the general preferences, Safari will open the installer, but nothing is executed until the user approves the install. Even then, unless you are foolishly running as an admin, the OS will require your admin password before the install can proceed.

I remember when I moved from PC to Mac I did the typical installation of antivirus/firewall/antispyware programs. The fact that many of these were shitty ports from PC versions should have tipped me off but I soon realized these served no purpose on my machine unlike my old XP machine where I wouldn't even think about plugging in an ethernet cable without my security suite all up and running to make sure nothing gets in and nothing gets run and the things that do get taken care of.

      This simply does not happen on Mac. I am sorry, but it is true. Yes, someone can make a trojan horse and generate a lot of media hype but that boils to someone tricking people into giving the malicious software a chance to run. There is only one way to handle that and that is by teaching people not to believe everything and be wary of what they download. Then you could have two equally informed users on a Mac and a PC who both avoid trojans but guess what. If the Windows users doesn't also have firewalls, antivirus, spybot, etc and a strong knowledge of how to use them (most users don't and these are loads more complicated than explaining to people not everything you here is true which is analogous to the real world) they are going to end up infected anyway.

    Give the Mac OS X Malware market time to mature. Mac OS X only recently became a "recognized target." Now Apple is trying to make it a "moving target" and a "reactive target" meaning they are essentially taking the Windows approach to security -- which is reactive. This means that with each new threat, a new response will be devised.

    They had an opportunity, early on, to create a heirarchical system that might protect the OS and, actually, I think they did... but we will see how it all works out. But when it comes to users installing and running programs at user level access? That's pretty much every OS, otherwise, such a system would not be usable at home or at the office.

    What makes malware laughably easy or difficult to remove is usually determined by how deep into the OS it can embed itself. With Windows, it happens a lot with increasing sophistication that targets not only the core OS, but also the countermeasures commonly deployed. So initially, in the absence of countermeasures, malware will target and run as the local users. When that stops working, it will find ways to embed itself into user applications (within those *.app folders that pretend to be entire programs) and then in the binaries that reside in the *.app folders... and then in user-accessible details in the OS and then in the OS itself as local exploits are discovered and run.
