RE: F-Secure: Sober.Y (Fake FBI e-Mail) Becoming Huge

["Debasis Mohanty" <debasis () hackingspirits com>]

I came across this worm in the month of Feb, 2005. Oh! so it striked back
again.. 

I did a quick reverse engg on this worm as then (talking about somewhere
around Feb, 2005) there were no advisory released from any AV vendor and
even virustotal wasn't able to detect it. I released a paper on it on 25th
Feb, 2005. The complete analysis can be downloaded from here :

Subject: [funsec] F-Secure: Sober.Y (Fake FBI e-Mail) Becoming Huge

We just took Sober.Y to a Radar Level 1 alert. Level 1 is the highest alert
we have. And this is the first Level 1 alert we've done in months.

Several millions of infected emails have been seen by internet operators
over the last hours.

One of the reasons why this email worm seems to be so successful in
spreading is that some of the messages it sends are fake warnings from FBI,
CIA or from the German Bundeskriminalamt (BKA). FBI has even put out a a
public warning on the case.

First Sober was found in October 2003, over two years ago. We believe all 25
variants of this virus have been written by the same individual, operating
from somewhere in Germany. Unlike most of the other widespread viruses
nowadays, Sober doesn't seem to have a clear financial motive behind it.

Some Sober variants have displayed neo-nazi messages, but the latest version
of the virus does not do this. However, all Sober variants send German
messages to German email addresses and English messages to other addresses.

The numbers we're now seeing with Sober.Y are just huge.

This is the largest email worm outbreak of the year - so far!
