[Declude.JunkMail] Decoding a html attachment

2004-01-22 Thread John Tolmachoff \(Lists\)
How would you decode the zipped attachment to see what it is doing? It is a
java script.

The attachment (unzipped) was attached to an junkmail with a bunch of
gibberish in the HTML body.

This one would be difficult.  Unless you have good math skills and a lot of 
patience, you would need to either run the code or write a program to do it.

In this case, it turns out to generate HTML code that goes to a page at

That does look troublesome...however...

The following JavaScript function is very spammy and can be weighted 
moderately.  The only things that should FP on such a thing are Web 
designers.  I have never seen this used before, so even among Web 
designers it should be rare.

BODY   5   CONTAINS   string.fromcharcode(

I left the parenthesis in so that you are protected from FP'ing on 
discussions of just the function.

Also note the following example that I found on Google:

   http://www.dragonswest.com/Spam.html

Ick. Someday not only will we need full MIME parsing, but also a full 
HTML and JavaScript decoder built in...For now though, this technique 
may very well prove more damaging than the non-obfuscated version if you 
use that body check.

 I  have  never seen this used before, so even among Web designers it
 should be rare.

That's  a  preferred syntax for Flash ActionScript. Can't tell you how
often  it's used in general, but it's all over one of our projects. So
web shops, or those corresponding with same, should be wary. It has no
reason to be in an HTML attachment, however; the combo is the red flag
to me.
