Hacking Cisco NAC - NACATTACK

Cisco mainly positions its NAC appliance solution which is widely deployed and is a very reliable solution and not the NAC framework mentioned. If the hacking was truly done, how come they did not demo it? and how come they did not talk about other vendors?

Seeing is believing: anybody can

talk and claim that they hacked any system and if there is no concrete proof and clear explanation of how testing was done and proper analysis and explanation of results, this information is simply worthless
