Apple Denies Wi-Fi Flaw, Researchers Confirm

Glenn Fleishman writes "Apple tells Macworld.com that the Wi-Fi exploit demonstrated at Black Hat 2006 in a video doesn't show a flaw in their hardware or software. A third-party USB adapter with different chips and drivers was used, and Apple says the two researchers haven't provided Apple with code or a demonstration showing a working exploit on Apple equipment. The researchers added a note at their Web site confirming that only an unnamed third-party adapter was used. This doesn't mean the researchers have no flaw to show, but rather that their nose-thumbing at Apple users who were too secure in their security was misplaced, at least at present. The researcher's claim that they were providing information to Apple now seems off-base, too."
