As always, ajohnson is right! 

First time I hear about this. I won't do this again, promise!

I'm thinking after a little bit this webcast will be available here:  http://www.rapid7.com/resources/webcasts.jsp

Did this ever happen?   I never got a reminder, and the signup is still open.

In this technical webinar for penetration testers, David Maloney discusses how to evade anti-virus detection on target machines to avoid detection. Participants will learn about:

    Signatures, heuristics, and sandboxes
    Single and stages payloads
    Executable templates
    Common misconceptions about encoding payloads
    Dynamically creating executable templates

Date/Time:

Thursday January 24th at 2:00PM ET
Speaker:

It’s been 7 years since we released our first version of BackTrack Linux, and the ride so far has been exhilarating. When the dev team started talking about BackTrack 6 (almost a year ago), each of us put on paper a few “wish list goals” that we each wanted implemented in our “next version”.

It soon became evident to us that with our 4 year old development architecture, we would not be able to achieve all of these new goals without a massive restructure so that’s exactly what we did and “Kali” was born. We’ve also posted a Kali Linux teaser on the BackTrack Linux site – and that’s all we’ll say for now…

How does this affect the Offensive Security courses? Surprisingly enough, with all the new changes we have made in Kali, the user experience remains pretty much the same. Our students should feel little difference between Kali and BackTrack. As usual, with our course upgrades, all alumni will be able to upgrade their course materials for a reduced fee. Students who have enrolled in PWB since the 1st of Jan, 2013 will get an additional discount on the upgrade fee –  once a new version of PWB is available, in the next 6 months. Our lab environment will not be changing due to the new BackTrack version. Be patient, we will release more information about Kali once it’s ready…soon.

Is it me or securitytube-training.com looks a bit too much like securitytube.net?
And there are many more other "megaprimmers".
Worth it.

tac is the reverse of cat. How clever!

I wonder if there are other commands that do things "backwards". 'bottom' instead of 'top' maybe? Although I don't see much of a benefit in that one hah

I was under the impression that the Professional version gave you access to some scripts that weren't included in the free one..? And is there a delay in plugin updates on the free one as well?

Many thanks for your response. What is your view of OpenVAS as a vulnerability scanner?
