Mac trojan multiplies but won't kill your dog

If users thought the Mac-targeted trojan discovered last week was a one-off, they'll need to think again -- security firm F-Secure has discovered 32 variants of it, but claims about its powers have been wildly overstated, acccording to experts.

"Looks like the Mac Trojan we posted about last week was not an isolated incident. The gang behind it seems serious about targeting Mac users as well as Windows users. And they keep putting out slightly modified versions of the Trojan for the Mac too," writes Mikko Hypponen, chief research officer at F-Secure.

Last week, Mac security software vendor Intego discovered a Trojan designed for Mac OS X being distributed via porn sites.
