Correct, you must take steps to remove wscript.exe and cscript.exe otherwise they will remain.-----Original Message----- From: lsi [mailto:stuart () cyberdelix net] Sent: Monday, October 27, 2003 6:04 AM To: Harlan Carvey Cc: incidents () securityfocus com Subject: Re: New Trojan Hi there,http://patriot.net/~carvdawg/docs/dark_side.htmlExcellent article on ADS, one point. You sayWindows Scripting Hoststarted shipping with W2K. However, it isapparently installed bydefault on Win98SE systems as well (I reinstalledthis machine justlast week). After reading your article I fired up a commandprompt and typedCSCRIPT - this caused the scripting host toappear. Which was odd,because I was sure I had told the installer *not*to install WindowsScripting Host.... So I click Start.. Settings.. Control Panel.. Addand RemovePrograms.. Windows Setup.. Accessories.. and sureenough WindowsScripting Host is *NOT* checked. However,CSCRIPT.EXE is in myC:\WINDOWS\COMMAND directory while WSCRIPT.EXE isin my C:\WINDOWSdirectory anyhow. So I would like to report to you: 1. WSH is shipped with Win98SE as well. 2. telling the installer not to install it doesnot work.Stuart On 25 Oct 2003 at 10:42, Harlan Carvey wrote: Date sent: Sat, 25 Oct 2003 10:42:41 -0700(PDT)From: Harlan Carvey<keydet89 () yahoo com>Subject: Re: New Trojan To: incidents () securityfocus comJay,I don't know if this is a new trojan oranything,but I have tried doing some research on theInternetand couldn't find anything on it. Well it hastworegistry entries in my Run, and RunOnce. Hereisthe name of both keys acbdhpd and the valuesarepointing to a file1129 I can not seem to find rundll32 C:\WINNT\system32:acbdhpd.dll,Init 1.Given the colon, it looks like you might have aDLLhidden in an alternate data stream. Is yourfilesystem NTFS?I tried killing my explorer.exe to see if thatisreason I can't find it because I am mostlikelyusing a trojanized explorer.exe,I'm curious about that statement, given that you really don't have anything to base it on.but I could only find a copy in my temp, I delete through DOSanddelete the registry entries to no success, the registry keys appear within 30 seconds and thefilepops right back up.What file? I thought you said you couldn't see anything, so what file is popping right back up?Anybody seen this or can give me some help to get this out withoutreloading? Ithas also opened up two TCP, 3799, and 41225and twoUDP ports, 1129, 1241. ThanksHow have you determined this? What tool areyouusing to determine that this particular issue is opening those ports, and they're not beingopened bysome other process? In a nutshell, it looks as if you've gotsomething onyour system, but it's hidden in an alternatedatastream. I'm willing to help, you can get me as"carvdawg" onAIM and "keydet89" on Yahoo Messenger.
