    DCOM part 2

    I just read this thread http://www.AntiOnline.com/showthread...hreadid=248386 and I believe dcom part "2" will release very soon from "the underground". They already started coding for the next worm. And some of them already have scanner dcom part 2 and this scanner made on base of MS-03-039:

    Code:

    On this subject Mr Gibson is ranting again.. here is his Cure All for this problem ..

    Thoughts on his rant?

    I question his opinion before following blindly.. I will not be using it blindly on ALL the Xp/Win2k Boxes that I am responsable for, nor on the machines I prepare for customers..I am about to test this on one of my machines here.. then run everything I can think of on/to/from the machine and see..


    Is his Idea a solution/bandaid.. ?

    Cheers

    I think it's fine for the masses Undertaker. It's surely better than leaving unpatched boxes swinging in the breeze. Also, since the proggie has the 3 commands you can always undo what it did, (testing it first of course..... ).

    Hi Und3ertak3r and TigerShark!

    I have always had a bit of a soft spot for Steve Gibson, and I have been following him for some years now OK he does "rant" a bit, but it is very well written "rant".......guess that's what sucks me in?

    I will try this proggy on some old boxes as a retrograde compatibility testing exercise.

    I think that TigerShark's comment is a good one..............good for the masses...........I would rather have everyone using Grisoft AV and ZoneAlarm free editions, than nothing at all.

    As we know, there are seriously dangerous people out there and thousands of script kiddies

    IMHO just taking the script kiddies out of the equation (making it difficult for them) would make the problem a whole lot easier to solve?.......then, I never was much good at Math(s)

    Cheers, have a good week-end

    Somehow I doubt Mr.Gibson's DCOMbobulator does anything more than change HKEY_LOCAL_MACHINE\Software\Microsoft\OLE --> EnableDCOM to 'N'. The buffer overflow occurs in RPCSS.EXE which to my knowledge is vital to the NT Kernel and therefore cannot be totally disabled, however the overflow occurs in a malformed DCOM request so turning of DCOM would do the trick. Just be aware many remote admin programs require the use of DCOM so if you enjoy being able to roll out patches and reboot machines remotely, maybe just patching your RPCSS might be a better idea, I know I'm not gonna do the next MS patch (and we know there's going to be many more) box by box I'll tell you that.

    Maybe someone can run his program and check the registry before and after?

    I started running Dcombobulator at work on a number of boxes that aren't vital... but get used constantly.
    I also set those to autoupdate and install daily. They are running NAV corporate edition with daily updates.
    I'll be sure to report any problems with patches or Dcombobulator.

    Hopefully this will save me from headaches from at least this group of machines.
