It can do it via port 3389? I doubt it. The subject is enumeration thru RSP that tool actually logs in and requires cred to the box and the RPC ports open Sent from my iPhone On May 7, 2013, at 2:40 PM, Rob Fuller <jd.mubix () gmail com> wrote:
Could just use findtoken / incognito from MWR, it will list available tokens on the box (supports ranges) http://labs.mwrinfosecurity.com/blog/2012/07/18/incognito-v2-0-released/ -- Rob Fuller | Mubix Certified Checkbox Unchecker Room362.com | Hak5.org On Thu, Apr 25, 2013 at 4:16 PM, Ryan <randomrhythm () rhythmengineering com> wrote:Microsoft Network Level Authentication (NLA) for RDP can also help defend against these "features" as it doesn't allow a full RDP connection until the user is authenticated.

Working with W7 I haven't seen it anymore but it may be that it's been disabled in my environment and I didn't realize it.

I don't know much about the windows API but might be worth looking at.Sent from my iPhone On 18 Apr 2013, at 01:36, Robin Wood <robin () digininja org> wrote:I've just noticed a nice little trick for user enumeration. The client I'm testing has RDP on almost every windows machine and when you connect to them, if there is a user already connected they tell you who it is. Luckily here most of them do have someone logged in. It is a manual job but has got me a nice little stash of usernames which is good as all my usual techniques failed. Of extra lucky, by naming and subnets I know which the servers are so I'm assuming users connected to them are either admins or at least have more privileges than a normal user. Thought others might find it useful.
