Remnants of the msblaster "beta test"


 note: I just opened up my router and got the following...

Note the pattern in the subnets and that I have not run a server on port
6667 in weeks,
suggests this agent ( proc32.exe = sdbot05b ) is still quite active and
virulent. samples of the log can be found at:
http://exploitlabs.com/attacking.zip  <--- log
http://exploitlabs.com/proc32.zip    <--- captured sdbot
http://exploitlabs.com/attack/sdbot.txt   <--- decompiled sdbot

this infection of the attacking systems was complete and in place
as of July 29, 2003 as recorded in this log preceeding that first attack
http://exploitlabs.com/attack/morning_wood-fun.txt
( this was logged by one of the attackers themselves )

my original paper can be found, here
http://exploitlabs.com/attack/RPC-DCOM-DDoS-attack.txt ( July 31, 2003 )

and is originaly referenced in response to obvious downplay of the DCOM -
RPC
issue, here
