Maynor finally reveals Apple wireless hack:

Security experts David Maynor -- "Can your wireless network be sidejacked?" and John Ellch -- "Hacking Exposed Wireless is a worthy addition to almost any IT library" -- finally disclosed their controversial exploit for gaining control of Apple computers. The exploit uses a flaw in the Mac's wireless driver as discussed in this paper published by Maynor on This September 17, 2007 InfoWorld Article mentions why Maynor waited so long to publish the hack:

"Maynor said that he had been under a nondisclosure agreement, which had previously prevented him from publishing details of the hack.

Many say that publishing the exploit now is a moot point, but Maynor says he just doesn't care what they think. "Let them tear me apart all they want but at the end of the day the technical merit of the paper will stand on its own."
