In spite of what the BlackHat USA 2013 page says, Chris and I both will be at BlackHat this year presenting a talk that will hopefully help folks understand 1) the problem of PTH and other credential attacks and 2) give folks some solid ideas on how to defend against it. We're also releasing some tools to help you guys out... I'm not going to spoil the fun, but you know that Chris is big into powershell, right? *wink*
Also, and it's not up yet, Chris and I will be heading back to Derbycon this year. We're really looking forward to it!
PTH Tools in Kali
I'm not sure if everybody saw, but one of the Kali devs did some pretty neat stuff to incorporate the most of the PTH toolset into Kali. For those of you who don't know Raphael Hertzog, here's his blog: http://raphaelhertzog.com/. He's a regular Debian contributor and I know he spent a fair amount of time working on getting PTH in Kali. He has a donations page, if you find the PTH toolsuite useful, please consider donating to him via Paypal. I just did!
