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."

Hardware: Hacker Publishes Notorious Apple Wi-Fi Attack 114 comments
inkslinger77 writes "It's been about a year since David Maynor claimed to have found a way to take over a Mac using a flaw in a Wireless driver. He's now published his work for public scrutiny. Maynor had been under a nondisclosure agreement, which had previously prevented him from publishing details of the hack, but the NDA is over now and by going public with the information, Maynor hopes to help other Apple researchers with new documentation on things like Wi-Fi debugging and the Mac OS X kernel core dumping facility."

The thing that's more concerning to me is that the tech news and media start sounding like CNN. It seems like anybody can step up and make a loud claim about something controversial, and the news sites just spread it around. Most other tech security claims are held accountable for documenting details and specifics, and being up-front about things like, "well, this only happens while using a random 3rd party wireless card, which would admitedly happen almost never on a Mac since most have built-in wireless...".

As for Apple zealots turning into "Intel Zealots" at WWDC05, well, you have to admit the new Intel Core is quite a step-up from their previous CPUs. And the Core 2 is (again) a big step-up too.
Just because something was good/bad in the past doesn't mean it's gonna be good/bad in the future (i.e. Mac OS 9 sucked but OS X is really good, Apple used to suck with their proprietary hardware and software (ADC, Apple-specific PICT screenshots that won't even load correctly in regular programs, etc) but now they're supporting standards (DVI, USB2, Wi-Fi, Bluetooth, PDF, PNG, etc).

The PowerPC G5 processor is an absolutely superior design to anything Intel was putting out in the 90s. I don't know of any hardware geek who disagrees, although they may disagree on real-world performance with available complete systems.
That Intel is putting out well-designed power-efficient processors today does nothing to change the past. That IBM is uninterested in desktop computer processors NOW and is allowing the G5 to languish does nothing to diminish the fundamental superiority of the processor design, or the performance advantage it had years ago during active development.
You may as well complain that car buyers today are just fanbois, because beack in the 60s everyone knew Japanese imports were lousy, cheap machines that barely stood up to American cars.

During the course of our interview, it came out that Apple had leaned on Maynor and Ellch pretty hard not to make this an issue about the Mac drivers -- mainly because Apple had not fixed the problem yet. Maynor acknowledged that he used a third-party wireless card in the demo so as not to draw attention to the flaw resident in Macbook drivers. But he also admitted that the same flaws were resident in the default Macbook wireless device drivers, and that those drivers were identically exploitable. And that is what I reported.

SecureWorks Alerted Apple About FreeBSD Flaw (Score:4, Informative)
"A number of news outlets and blogs have picked up on these various statements and clarifications, but nowhere have I seen this tidbit: Apple's Fox said that prior to the Black Hat demo, SecureWorks did contact Apple about a wireless flaw in FreeBSD, the open-source code upon which Apple's OS X operating system is based. In January, FreeBSD released a patch to fix the problem, which according to the accompanying advisory, related to a flaw in the way FreeBSD systems scanned for wireless networks that could be exploited to allow attackers to take complete control over the targeted machine.
I looked through the last eight months of patches from Apple and could not find any evidence that it also shipped an update to correct this flaw. Fox said she would check with Apple and get back to me. Fox also said Apple staff were already aware of the flaw when SecureWorks contacted them about it prior to their Black Hat presentation, and that Apple had already determined that the wireless flaw addressed in the FreeBSD patch was not exploitable on any of the Mac products.
"SecureWorks has not be able to exploit this for us," Fox said. "No one has been able to show us a way to exploit our internal [wireless] device drviers with that flaw."

But in reality every laptop sold by Apple today ships with an Airport card, and most of the ones sold previously had one as well. What message are you really sending when you trumpet a flaw that affects 1/10 of 1% of Mac users?
The message that Mac users should be aware of possible security vulnerabilites is an excellent one but hyping a vulnerability that would simply not happen in reality was a poor vehicle to convey this message, and basically comes off as self-aggrandizing; that is to say they were far more interested in promoting themselves than warn Mac users about security flaws.

Anyway, my original point was, don't say "no Apple users ever use third party hardware / drivers" but few do. And in this specific case very few would as wifi is 99% of the time already in your laptop so there is no need for a 3rd party wifi card/driver. In addition 3rd party wifi cards and drivers are damn rare for Macs. Well, you can pick up any USB wifi adapter, but try to find vendor supplied/supported drivers for the mac (there are plenty of open-source drivers trying out there).
Let's face it, the security team wanted to get noticed and bashing Apple's security was an easy way to do it. They got their 15 minutes of fame. Now people are looking at what they said and did and finding the flaws in what they did. If someone had looked at what they were doing beforehand the whole thing would have been laughed off..

Given the hackers comments :
Although an Apple MacBook was used as the demo platform, it was exploited through a third-party wireless device driver - not the original wireless device driver that ships with the MacBook.

That's a poor way to look at it, and masks the situation you have with the Mac market today.
Any of those 92% of computers may vary wildly in terms of OS loaded or software used.
With the Mac you have tens of millions of computers (fourteen million registered OS X users). Lots of them are running the same software, the same browser, at the same OS rev.
Looking at the cost of renting botnets on the grey market those millions of computers represent millions of dollars of revenue, even if you crack just a percentage of them. So the question is why would someone leave that money on the table?
The answer is obvious - because it's a lot harder to hack a Mac to use in such a way. So it's not really numbers that are preventing the serious development of attacks today so much as a stronger security model. This would potentially be true even beyond the 80% marketshare point.
Basically the reason the Mac is safer today and will continue to be so even as market share climbs is the same philosophy behind avoiding being eaten by a bear - you just have to be able to run faster than the guy next to you. Windows is puffing something fierce.
