Just got this in a e-mail from Message Labs.

General

The details of the new virus are as follows:

Virus name: W32/Sadhound.A

Number of copies seen so far: 2,704

Date first Captured: 25th Jan 2003

Origin of first intercepted copy: Netherlands

Number of countries seen active: 1

Most active countries: Netherlands

Technical Details

On 25th January 2003, MessageLabs intercepted the first copies of a new virus called W32/Sadhound.A. To date, all of the copies that we have thus far stopped all originated from the same IP address in the Netherlands. Therefore, at this time, we are unsure as to whether this is a seeding of a trojan, broken malware, or a mass-mailer.

Initial analysis suggests this is a dropper-program, depositing a mass-mailer with a backdoor and a mIRC component; however, this has yet to be confirmed.

From the copies that MessageLabs have intercepted, the email may be composed as follows:

Subject:

I Miss You

The email body contains the following text:

I Miss You…

Attachment file names include:

Bloods.jpg (11,507) – a picture of a sad-looking bloodhound,

hence the name

bgg.jpg (2,680) – a background image

Missingyou.htm .pf.htm – or Missingyou.pif (11,296) since the name

and filename are different in the MIME header.

Detection

Skeptic™ detected W32/Sadhound.A heuristically. No MessageLabs customers were affected.
