In the script kiddies world, it's pretty common to take a binary, open
it with a hex editor and change some parts like IP addresses and
embedded strings to create a new variant of the worm: no source code
is used.

This means that most "authors" are probably completely unrelated to
one another. getting the guy who wrote the initial source code is
probably the best you can hope.

Good luck,
