From the horse's mouth

The guy who hacked a mac in the first 20 minutes of the rm-my-mac comp isn't impressed with Mac OS X security.

Gwerdna concluded that OS X contains "easy pickings" when it comes to vulnerabilities that could allow hackers to break into Apple's operating system.

"Mac OS X is easy pickings for bug finders. That said, it doesn't have the market share to really interest most serious bug finders," added gwerdna.

I wonder if this will be a new trend for all those mac-ians who barely know how to open an xterm yet are adamant they have the most secure operating system in the world? :)

OS X still kicks arse though :)
