Subject: [SECURITY] "postcard" spams.

We've been receiving a whole host of "You have received a postcard!"
spam, with malware website links embedded in it.

For details, see: http://isc.sans.org/diary.html?storyid=3063

I haven't had a whole lot of luck finding information on the method of
propagation on this, but it seems to do all of its initial setup from a
source UDP port of 26395. At least, that's my observation from a
deliberately infected machine and a packet sniffer.

Does this jibe with other people's observation of this? The ecard.exe I
downloaded from one of the emails has a different MD5 than listed in the
SANS article, so I fear there might be copycats and variants out there
already.
