The worm skips the email addresses containing:
arcor
bigfoot
hotmail
online
web
yahoo

Technical DetailsWhen activated, Worm/Sober.E copies itself as %Systemdir%\%random filename%.exe. The random name is formed out of the following strings:
sys
host
dir
explorer
win
run
log
32
disc
crypt
data
diag
spool
service
smss32

It makes the following autostart registry entries: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion \RunOnce "%random entry%"="%Systemdir%\%random filename%.exe%1"

It creates the following files:
%Systemdir%\msWord.wrd
%Systemdir%\MsHelp32.dat
%Systemdir%\WinRun32.dll (a logfile, containing the list of collected email addresses)
%Systemdir%\bcegfds.lll
%Systemdir%\zmndpgwf.kx

The worm starts Microsoft PaintBrush or displays a message:
"Graphic Modul not found".

If the system is not connected to the Internet, the Threat tries to spread using all available Dial-Up connections and eventually displays a message:
"Microsoft Windows STOP: 0x80070725 {FatalSystemError}
System File [filename].exe
Connection lost or blocked by Firewall"

The worm contacts one of the following Network Time Protocol (NTP) server through TCP port 37, for establishing the date:
Rolex.PeachNet.edu
ntps1-1.cs.tu-berlin.de
ntp2.fau.de
ptbtime2.ptb.de
time.nrc.ca
ntp.metas.ch
ntps1-0.cs.tu-berlin.de
ntp0.fau.de
timelord.uregina.ca
ntp-1.ece.cmu.edu
ptbtime1.ptb.de
time.ien.it
ntp3.fau.de
time.chu.nrc.ca
clock.psu.edu
ntp1.fau.de

If the date is past March, 24th, 2004, the worm downloads the file %Windir%\ndhaqqth.exe from one of the following websites, through TCP port 80:
home.arcor.de
people.freenet.de
