    Local Password Exploits and Countermeasures Presentation (Flash Tutorial)

    Local Password Exploits and Countermeasures Presentation (SAM/Syskey, Domain Cache, VNC & Protected Storage)


    I have finished a Flash version of the Local Password Exploits and Countermeasures presentation Iím working on for the Indiana Higher Education Cybersecurity Summit (http://www.indiana.edu/~cacrsum/program.html). It covers cracking the SAM/Syskey, Cached ADS/Domain Credentials, VNC stored passwords and Windows Protected Storage

    Here is the link to see the tutorial:

    http://www.irongeek.com/i.php?page=v...sswordCracking

    Itís about 5.3MB and has almost 30 min of audio in it. Don't mirror it anywhere yet as I may change it some before I present it live on the 29th. If you have any feedback you would like to give me before the 29th email me. The Flash file may have some bugs so let me know if you find any.

    Sounds good so far. You might want to mention that the sam file is in a hidden folder and not accessible under normal Circumstances???

    I'll post again as I go through it. I Take it that is why you are posting??

    When you talk about VNC. In the visual presentation the first app is Realvnc and second is tightvnc. Your dialog is tightvnc first realvnc second.

    Nitpicking, I no, but so much more on the ball if it matches.

    Cool, I can change that. I'll wait till I get a few more comments so I can do all the changes at once then upload it again. Thanks for the feed back Jinxy.

    Ok jinxy, I made the VNC change. I also fixed some typos and added the factoid about. If you use a password longer than 14 characters no LM hash will be stored

    Well, I did the presentation Friday and it seemed to go over pretty well. Just st-st-stuttered a little bit. I added a section on using Cain to crack cached domain credentials, and was done with it. Fell free to mirror it if you like. Thanks folks.

    What the...?

    "Pistol Packing Penguin?"

    Heh.

    Good tut btw - did you want any feedback still or not, as you have already presented? How did the audience receive it - a lot of questions/comments back to you?

    Gracias.

    I did not have a lot of time for questions, but some people came up to me after the conference. If you have any constructive criticism to give go ahead.

    Here is a question for anyone who knows. In IronGeeks nice presentation he mentioned Protected Storage. Now is Protected Storage the same thing as LSA(Local Security Authority) Secrets? Which are also stored in the registry, but I"m not sure where.
