By exploiting several weaknesses in Apple’s file system, (Leap-A) and its successors will work.” One more thing: there was talk a while back that Apple’s move to Intel chips would make the platform more susceptible to malware like this. But Leap-A is a PowerPC worm. Does that make Intel-Macs invulnerable?
