I’m sorry I have been gone for a while, but,  I got caught up in conferences and final projects/exams, and I lost control of my schedule.

Something important happened while I was gone, though, the Flashback Trojan!  We have discussed trojans before.   They are similar to viruses in that they disrupt the operation of a computer or make your computer vulnerable to data theft or keystroke logging,  or other things.    They are different from viruses in that they cannot infect another computer.   What makes this particular trojan interesting is not its structure or action, but rather that it was directed to a Macintosh.  My friends and colleagues who use Macintosh computers have smugly reminded me for years that they do not run virus protection software on their computers because they do not need it;  Macs don’t get malware.   Yet on April 5, it was reported that over 600,000 Macs were infected with this trojan.  This malware was initially found in September 2011 masquerading as a fake Adobe Flash Player plug-in installer, but it has also exploited Java vulnerabilities to infect Macs.

Do you wonder if you have it?  Check the security company F-Secure, which has published instructions on how to determine whether a Mac is infected with Flashback.  If your computer is infected with the trojan, you can learn how to remove it from CNet.

This is not the first malware product lately to infect the Mac, but it was the most widespread. The question you may be asking right now is WHY????  As I said, most Mac users do not bother with malware protection because to this date they have not needed it.  Yes, it is true that the Mac operating system has fewer holes in it to exploit when compared with Windows.  Yet, I believe there is more to the story.  Historically there have been many more Windows-machines than Macs, and they tended to be more pervasive in industry.  If your goal was to cause significant disruption or to steal data and identities, you would get a bigger bang associated with Windows machines than Macs.   I believe that is exactly what malware writers have been doing.  However, the Mac isn’t just for schools and artists anymore, it is being used in more businesses and by more people.   It stands to reason that more malware will be written for these machines, especially since there are less people protecting the Macs and few companies that are actively involved in research into the attacks.

So, what does it mean for you?   I would recommend that you purchase anti-virus software and use it.  That is, you not only need to install the software, but you must update the virus patterns weekly (if not more often).  Second, you need to be careful what attachments you open.  If you are suspicious, do not open it.  That holds for updates too.  Research what is being updated and whether that popup is legitimate.  Be careful — even with solid doors with locks, you must be vigilant to insure the burglar does not steal your possessions.  The same is true with the protection of your computer.
