MacBook wireless hack demonstrated.
"The pair have found ways to seize control of laptop computers by manipulating buggy code in wireless device drivers. In a videotaped demonstration at the conference, Manor showed how to use sophisticated hacking tools to add and remove files on a Wi-Fi enabled MacBook, manipulating the system from an adjacent laptop computer... Wireless devices are designed to be constantly sniffing for new networks, and this can lead to security problems, especially if their driver software is buggy... By exploiting bugs in four different wireless cards, the researchers found ways to seize control of laptops running Windows and Linux as well, they said."
