Wednesday, November 5, 2003 In our never-ending quest for entertainment, we commece from this date forward to end-2004 our POS series of findings. 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 ! Be aware of html files out there. -- http://www.malware.com
