Mac Users May Meet Windows Threats

Users installing Windows XP on Intel-based Macs face some special security issues, a security expert said Thursday.

By applying Apple Computer's just-released Boot Camp, Mac owners can now create a dual-boot system that runs either Mac OS X or Windows XP. It's the latter that worries Ken Dunham, the director of the rapid response team at security intelligence firm iDefense.

"When a Mac is booted into Windows, it can be attacked by the same [exploits] that threaten any Windows PC," said Dunham. "If you're running an unpatched version of Windows XP on any box, it'll be hacked pretty quickly."

Of the two operating systems, "naturally with Windows you're more at risk," said Dunham. Neither Mac OS X or Windows are invulnerable to attack -- the former was the subject earlier this year of its first zero-day bug -- but the latter is, by far, the one that draws most attacker attention.

But it's not the vulnerability of Windows that concerns Dunham; it's the fact that the Mac will have multiple operating systems on its hard drive.
