Time to Protect Your Macintosh Computer

Over the years I’ve attended a number of conferences and panels on what originally was called Spyware and Adware. I think we’ve finally settled on using the term Malware for any kind of spyware, virus, Trojan horse or any kind of unwanted computer invasion. I fondly remember my first conference in Washington DC which included panel discussions like “What is Spyware”.

I will also never forget, Jeff Fox, who at the time introduced himself as an editor from Consumer Reports magazine. Jeff insisted the Macintosh was “less hospitable” to spyware.  It had nothing to do with the Mac’s 1.5% market share, Jeff implied, Apple created their OS with less vulnerabilities. Ed Skoudis from SANS Institute, countered noting that, “OS10 has had a number of significant security flaws” and that they’re not as widely publicized because they don’t impact as many people.

Since that time Apple has widely increased their visibility. Some estimates put the Macintosh market share above 14%. While many malware authors are targeting the iPhone and iPad, it appears someone has created a Trojan Horse that has spread to over 600,000 Macs including hundreds of machines that report their address coming from Apple headquarters in Cupertino.

If you own a Macintosh computer there’s a chance you’ve been infected even if you run some kind of Anti-Virus software. If you’ve been on a website that offered to update your Flash player, there’s even a better chance you’re one of the 600,000+.

Apple has provided an update with instructions click here. The so called OSX/Flashback Trojan uses a flaw in Oracle’s JAVA. Both Apple and PC users that depend on JAVA should be sure they have the newest version available. PC users who use JAVA click here. Macintosh users should update their software at http://support.apple.com/kb/HT1222 as soon as possible.

Special thanks to our friends at F-Secure labs for their research and Kaspersky Labs who reverse engineered Flashback and were able to verify the number of infected machines by setting up their own bot honey pot based on the Flashback code.  Read more here.

It used to be once a month someone would ask if there is a version of WinPatrol for the Mac.  Lately it’s been 2-3 times a week. I was able to secure the domains LinPatrol.com and DroidPatrol.com but MacPatrol was taken by the time I tried to register it.

Thanks Apple Mac Support London. It might have been more useful if you included some links to these methods like Corrine did with her links.

So tell me, my wife has a Mac, of which I know nothing. What programs
(shareware I hope) should she have on it to 1. Protect it. 2. Keep it in good running order? 3. Make sure it isn't infected by malware.
