this is not "detailed" ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
rather a joke, are there any real forensics people employed by any AV
vendors?
lol, looks like pada works REAL hard to by looking at
http://www.pandasoftware.com/virus_info/encyclopedia/extended.aspx?idvirus=39542&sel=EXTRA
( theres a file with optix package called "FirewallsAVS.txt" )


a brief review will show:

optix pro server is generaly 896k - ( 383k packed )

upx is the prefered method of packing and running
"upx -d suspectfile.exe" should unpack a server for
string analysis ( bintext by http://www.foundstone.com/ works great for
this )

some unpacked strings:

EES_Encrypt
( a "krew" packer )
CD tray is open!
Blue Screen Complete!
( funny, commands embeded to do this are.. "aux\aux\d.t" and
"con\con\d.t" )
Removing Enhanced Technology...Pls Wait...
s7 special
( start method )

as well as full FTP commands

Simply downloading the R.A.T and viewing the binaries, you should be able
to compare
the strings.

  As a further note on "worms" and the RPC-DCOM threat:
utilising a program such as the type from the KaHT webdav auto-exploiter
would automate this,
looks like they already did it :
http://www.terra.es/personal7/atar2000/kaht2.txt

IMHO a worm is not needed by this exploit as its easy to scan,
hack ( dcom.exe ),
drop ( a real worm (  sdbot ring a bell? ))
when using a autohacker that could easily be set up on zombied (
compromized ) systems to
compromize, hack, drop with imunity.
