    So, releasing a worm that does nothing but warn the world and getting
    the holes patched? I would agree this is stupid from a black-hat's
    point of view, but I think it's better that some kiddies exploit and
    expose the vuln/exploit than some organized criminals. Have you ever
    done something for the kick off it? The message I'm replying to now,
    is there a point? Except saying they are stupid?

    It is possible for the authors to replace the scripts and hence, load
    different payloads as time goes, it hasn't been done, but it is a
    possibility. I would say this is harder with self-carrying code.

    Agree with this one, it's not very "nice" code to look at, especially
    when it's in some strange foreign language.

    I myself are fascinated by worms, but then again I'm not a real programmer.

    My two cents

    Full-Disclosure - We believe in it.
