Speaking at the Black Hat conference in Las Vegas Wednesday, iSec founder Alex Stamos and his team of researchers took a look at the typical stages of an APT attack — and compared how the Mac would do versus Windows 7. Their conclusion: Macs provide good protection against the initial phases of the attack, but once the bad guys are on the network, it's a whole different story. 'They're pretty good for [protecting from] remote exploitation,' Stamos said. '[But] once you install OS X server you're toast.'"
