FYI, In the html source, the binary is converted to 2 digit hex and then converted to decimal. For example, the first part of the executable array is: jelmersArray= array(77,90,68, The beginning hex of the executable looks like this in hex: 4D 5A 44 01 05 00 02 00 Convert 4D from hex to decimal and you get 77. 5A is converted to 90 44 is converted to 68 you get the point! -----Original Message----- From: Compton, Rich Sent: Thursday, November 06, 2003 12:36 PM To: 'Bart.Lansing () kohls com'; full-disclosure () lists netsys com Subject: RE: [Full-disclosure] POS#1 Self-Executing HTML: Internet Explore r 5.5 and6.0 Part III How is this binary converted to the array in the source and then converted back to a binary??? Anybody have information on how this is done? This makes me very worried! This could bypass all the antivirus filters that remove executables! -Rich Compton -----Original Message----- From: Bart.Lansing () kohls com [mailto:Bart.Lansing () kohls com] Sent: Thursday, November 06, 2003 9:26 AM To: full-disclosure () lists netsys com Subject: Re: [Full-disclosure] POS#1 Self-Executing HTML: Internet Explorer 5.5 and6.0 Part III Has the Win2kSP4/IE6.0 combination been confirmed as immune to this? full-disclosure-admin () lists netsys com wrote on 11/05/2003 04:36:16 PM:

That is the 'perfect operating system'. Today we debut and regurgitate new and not so new for fun as follows. A warm up for the New Year if you will !: The following file is an html file comprising both scripting and an executable [*.exe]. We inject scripting and an executable into the html file which is designed to point back to the executable in the html file and execute it. Provided the html file is an html file, Internet Explorer 5.5 and 6.0 will execute it. Because it is an html file proper, Internet Explorer opens it. The scripting inside is then parsed and fired. That scripting is pointing back to the same executable file and because it is a self-executing html file, it executes ! Fully self-contained harmless *.exe: CAUTION: back up notepad.exe before opening http://www.malware.com/self-exec.zip What a POS !
