Right. Its better to give crackers less information versus more. so others do not get login credentials. Though, if certificates were properly implemented, there would be mutual authentication On Tue, Apr 7, 2009 at 8:12 AM, Arran Cudbard-Bell a.cudbard-b...@sussex.ac.uk wrote: -BEGIN PGP

I'm aware of an attack on a bank which had implemented EAP, and had fun when a Pen tester was simply getting domain login credentials without having to work much at all. Could you maybe provide a rebuttal for this attack? and/or explain how to make it especially secure? On Tue, Apr 7, 2009 at

Hi, thanks for the list I can confirm all of these issues. Also, if you have WPA/AES turned on, then the Mac wont touch the lovely WPA2/AES - ie it wont do 802.11n properly. if you reratify the wifi so you only do WPA/TKIP and WPA2/AES then the Mac is a _little_ happier I can also confirm

Hi, Have you actually traced the wireless traffic (passively), are you sure it's the Macs at fault with this one? as everything works fine on the same Mac when it runs Vista (yes, I know...) and works all okay on random PCs and PDAs/smartphones..the big greasy pointy finger is pointing
