Scareware comes to Mac OS X!

Windows users may be used to reading about scareware, but it now appears that scareware has made its way to the Apple Mac computer. A fake antivirus program calling itself the MACDefender is attacking Apple Mac computers.

This fake antivirus program called MACDefender, targets Mac users via SEO poisoning attacks, after the user visits particular websites, reports Intego.

When a user clicks on certain links after searching for a query, they are sent to a website that displays a fake screen showing a malware scan. The window then tells the user that their Mac computer is infected.  After this, a JavaScript on the page automatically downloads a zip file. If the user continues the process, the rogue software gets installed.

For long has Windows been the most favored target of malware writers by virtue of its sheer market numbers. But now that Mac useage has crossed the threshold of 10%, it looks like such attacks may become a common thing.

In fact a do-it-yourself crime kit for making Mac malware is now also available on the net!

In the past, these types of sites only delivered Windows rogue software applications. The fact that such sites are now  providing a Mac rogue antivirus must be disconcerting news for Mac users, who believe that they do not have to worry about malware, unlike Windows users.

Several Mac users who were infected by the MAC Defender app have posted questions on asking how to get rid of the application.

    It’s about time these criminals share the love with Mac users. I get so sick of hearing how Mac users (all 10 of them) do not get viruses, malware, etc. As a Windows user, I can say that I haven’t had a virus or malware in 10 years (knock on wood).

    I’ve been saying this for years. Macs are just a vunerable to viruses and maleware and have just as many security holes as a Windows PC, it’s just no one ever bothered because there were too few of them. Welcome to our world Mac users ! LOL
