This worn written by VC++6.0 and compressed by UPX. Its size is 10240 bytes.
The worm's aim is to remove the msblast anf patch the system,which infects
by RPC DCOM and WebDEV.
When it go into the system ,it copy %systemroot%\system32\dllcache\tftpd.exe
to %systemroot%\system32\wins\svchost.exe ,then create the service named
RPCTftpd ,and its Display is ""Network Connections Sharing".
And then It copy himself to %systemroot%\system32\wins\dllhost.exe ,then
create the service named RpcPath .
3rd,the worm will check the process "msblast" and remove it ,then download
the patch form the M$ according diffrent language version,and patch system
with parameter "-n -o -z -q".
Then it scan the subnet with ICMP filled with ,whose type is "echo" and size
is 92 bytes ,so there are large volumes of ICMP traffic in network .when the
worm find a host ,it will try to infect with RPC DCOM and Webdev, If sucess
it will listen a TCP port less than 1000 to send the file.If the year is
2004,then it will remove itself.So the easiest way to remove is adjust your
It seems it is a "good " worm to clean msblast:)
