The recent Flashback Trojan was just the beginning of a battle against malicious software for Mac OS X users, according to the head of the Kapersky security firm.
Eugene Kapersky, founder and CEO of the anti-virus empire, says cyber-criminals would continue to target Mac OS X and says the software is no more immune to infection than Microsoft's Windows operating system.
And, unfortunately for iMac and MacBook users, Kapersky reckons Apple is a decade behind Microsoft in dealing with the malware threat.
He says that Microsoft's market dominance is responsible for the majority of malicious software appearing on Windows, rather than the long-held notion that Apple's desktop and laptop solution is virus proof. As Apple's share of the pie continues to increase, Kapersky says, cyber criminals will yield greater results from focusing on the software.
"I think they (Apple) are ten years behind Microsoft in terms of security. For many years I've been saying that from a security point of view there is no big difference between Mac and Windows," he said.
"(It's) just a question of time and market share. Cyber criminals have now recognised that Mac is an interesting area. Now we have more, it's not just Flashback or Flashfake. Welcome to Microsoft's world, Mac. It's full of malware."
"Apple is now entering the same world as Microsoft has been in for more than 10 years: updates, security patches and so on. We now expect to see more and more because cyber criminals learn from success and this was the first successful one."
The Flashback Trojan, which is believed to have infected 600,000 Macs earlier this month, was shot down by an Apple software update, although Cupertino has earned some criticism for the time it took to acknowledge and extinguish the problem.
