Mac as a means of distributing malware
On several occasions I have spoken on this blog and in interviews about our take on IT threats for Mac. There is a widely held view that Mac users are in no danger, as viruses are only designed for Windows platforms and because the Mac operating system is more secure than Windows. The truth is that there are viruses that operate in the Mac environments. The difference lies in the amount of malware circulating in comparison with threats designed for Windows. The explanation is simple: If you are a cyber-crook trying to profit from your activity and you want to infect as many victims as possible, what is the ideal target? A platform with 100 million users or one with 1000 million? The answer is obvious.
I’m also convinced that as the number of Mac users increases and as it reaches a significant market share, hackers will begin to find an inviting breeding ground for distributing their infections. I would go so far as to say that they will find victims unprepared, precisely thanks to the false sense of security that Mac users have. Therefore, when this happens, the situation could well bring back memories of some of the notorious epidemics such as Nimda or Sircam. And regardless of any presumed absence of viruses, Mac users are just as vulnerable to spam and phishing.
In any event, it is important to underline that although there may be less malware designed specifically for Mac, and the chances of infection may be lower, this has no bearing on whether Mac users are contributing (knowingly or unknowingly) to the propagation of IT threats. Perhaps unwittingly, many of them will be infecting Windows users connected across various channels (email, social networks, etc.). We should also bear in mind that Mac users often have Windows installed on separate partitions, or distributions that allow them to share files with Windows, and that it is practically essential to have an antivirus installed on these partitions.
In our business, we would say this is another infection vector. There are a couple of scenarios that illustrate well the reality of malware distribution in these environments: the exchange of information via USB devices (pen drives, hard disks, cell phones…) which are connected to both Mac and Windows systems, on the one hand, and on the other, Mac codecs, which are becoming a popular trend for hiding malware. These situations are just an example, but if we stop to think, there are many cases where using a Mac platform without protection is a risk for the users themselves and for others that come into contact with them.
Finally, regarding the myth that the Apple operating system is more secure than Windows … we’ll talk about that another day: -)
