Honestly I anticipated it to hit my spam trap sooner or later, since it has already been discussed in NANAE here and here. The spam contains no body, just the attached pdf file. The file itself didn't seem to be harmful:
Quote:
[olliver@bunkiten tmp]$ pdfinfo document-ed1064e.pdf
Error (0): PDF file is damaged - attempting to reconstruct xref table...
Tagged: no
Pages: 1
Encrypted: no
Page size: 474 x 191 pts
File size: 16223 bytes
Optimized: no
PDF version: 1.3

Opening it just reveals the usual penny st0x we know so well...

Email headers:

Subject: document-ed1064e.pdf attached
Content-Type: multipart/mixed;
boundary="------------080507000602070007040604"

(emphasis added by me)

The spam was sent by this machine:
Quote:
[olliver@bunkiten tmp]$ host 66.168.129.5
5.129.168.66.in-addr.arpa domain name pointer bb.rcom-ne.com.
5.129.168.66.in-addr.arpa domain name pointer tickets.rcom-ne.com.

Belongs to Charter and has already landed on many blacklists, but doesn't seem to accept connections to port 25 at the moment.

24.213.185.7 is a compromised machine somewhere in the Cazenovia College in NY:

the PDF shows the same characteristics as the previous one:
