Subject: possible MS03-026 worm?

Not I that was scanned or exploited, but anyway...
As my subject stated my belief is that it was a possible worm. Who knows
I am not a programmer and couldn't disassemble to save my ass - which is
why I pass it on to others with the skill to do so.

I've heard from some sources that the dcomx.exe may contain an IRC
"auto-rooter" / w32/lolol.worm.gen

so what your saying is that you have been scanned using a rpc scanner, a
rpctest was used to determine your operating system, tftp was used to
upload
files and the rest can be anything from winmgnt.exe to servudaemon.exe
for
opening a ftp server on your box, the worm.exe just looks like a neat
batch
file for ease of transfer of files and the spawning of a shell is simply
the
dcom rpc windows hack program in operation.

So have we a worm or have we a slight chance of over reactive paranoia
through naming of files?
I value your need for valadation, and maybe I am wrong and the rpc worm
is
out to kill folk,
I hope my explanation is the one, anyways bring the worm on, I am
patched,
stormfront installed, full checkpoint ngfp3 suite and a network patching
program to foil the world hehehehe

Enjoy ya weekend.

Fortunately
without any damage to our systems. The worm seems to check hosts with a
funny ryhtm within a Subnet:

The
coder must be stupid/[totally stoned] or simply made a mistake coding
the
loops for scanning.
