Anyone who saw your worm on their machine and could identify where it
came from.

There's a user on Astalavista.net saying that he made a "counter-worm" to
nullify this w32.blaster.worm. says he coded it in VC++. i havent seent the
code myself, but have seen that others at the site that have, give it props.
Says it can block 4 of the 6 variants...or something like that. the whole
legality discussion went on there too. Personally i think its a good idea to
try and combat the thing, legal or not. who would really sue for trying to
block it? unless M$ created it. oh well

You would be stepping on a lot of toes by doing that.  Not to mention
breaking several laws.

This hack patch discussion has been had before.  The area sounds appealing
but when it comes down to who is responsible if the "Patch Worm" breaks my
"whatever" it starts to loose its luster.

Hi,

Is it not possible to create another worm or modify this worm to
actually patch the machines? :)
Looking at the Symantec removal tool there is a silent mode.. A few
days back I was on the Microsoft site and I also saw an option for a
non interaction install for the RPC patch but looking through the
site now I cannot find it :(
The "fixing worm" could scan for 2 hours then purge itself?

Just a thought

Stu

Symantec has made a tool available:

ol.html

A friend told me that it works.
