Hi Guys,

I havent posted these warnings for quiet some time.. decided to with this one..

It uses one of the common SE tricks.. The copies I have recieved dont exacxtly fit the descriptions on Symantec..

SOBER.O is the threat
Current status @ 22:25 May 2nd 2005: Cat 3
High distribution capability
High Incedence in the Wild
Low Damage

AV info HERE

W32.Sober.O@mm is a mass-mailing worm that sends itself as an email attachment to addresses gathered from the compromised computer. It uses its own SMTP engine to spread. The email may be in either English or German.
My personal warning.
Reject/delete/ignore any mail delivery messages that dont come from your own ISP.. and treat with extreem caution any that come from your own ISP.. You should be aware of the format of the error messages from your own Mail server..in other words.. treat even messages from your own server with caution..

the following are the headers of a pair I decided to play with this morning..

ok just got this from Trend:

As of May 2, 2005, 11:50 AM (Pacific Daylight Time/GMT -7:00), TrendLabs has declared a Medium Risk Virus Alert to control the spread of WORM_SOBER.S.
TrendLabs has received numerous infection reports indicating that this malware is spreading in Germany and the U.S.A.

This worm spreads by mass-mailing copies of itself using its own SMTP (Simple Mail Transfer Protocol) engine. It gathers its target recipients from files with certain extensions names. Notably, it avoids sending messages to addresses that contain specific strings.
Using social engineering techniques, it sends out an email supposedly sent by the soccer organization FIFA, informing recipients that they have won tickets for the upcoming FIFA World Cup 2006 in Germany.

The email it sends out has the following details:

From: (any of the following)
. Admin
