Black Hat: 'This network is hostile'
From the "I don't think we're in Kansas anymore Toto" files:
LAS VEGAS -- Aaaaaah Black Hat, where all that ails computer security is out in plain view, even some stuff that you normally can't see like Wi-Fi. I go to many conferences over the course of any year but only one, only Black Hat provides its attendess with a disclaimer about Wi-Fi.
This Network is hostile
That's what it says on the Black Hat sheets telling users how to connect to Wi-Fi here. Sure any Wi-Fi network could be hostile (and really all public ones should be considered as such) but they've spelled it out very plainly here.
To make matter even more (in)secure - this year the Wall of Sheep is part of Black Hat. The Wall of Sheep will detail users here at Black Hat that connect insecurely (over the hostile network). Specifically it will look at users who sent their passwords in the clear.
It's actually a very good exercise since all this 'fun' is being monitored under the guidance of the Black Hat conference as a learning kind of tool. Other conferences (and public Wi-Fi) present the same risks too, even if they don't advertise it.
