Mac security firm Intego believes so. "The past year has seen a huge increase in Mac malware. Not only are malware creators targeting Macs more, but they are also improving their techniques. The code in this new Trojan horse is very sophisticated and shows a good knowledge of Macs," said Peter James, global spokesperson for Intego.
When asked to provide figures to substantiate that malware authors were targeting Macs in much greater numbers, Intego did not do so.
Rich Mogull, analyst and founding CEO at the IT security research firm Securosis, says that while there may be an uptick in Mac malware -- and there have been some security design mistakes -- the threat landscape for Mac users hasn't changed very much.
"The default trusting of installer packages is something Apple should change, but it's a setting users can correct themselves," Mogull says. "As for the risk of increased malware, that's not something I'd be concerned about. It's not as if OS X is going to experience the type of malware problem we all saw with Windows XP," says Mogull.
