    That's good. Only 2 more to go and then they'll have to stop writing variants!

    Or am I missing the point?

    I think the question is: why are the variants so successful? I mean, we're getting to the end of the alphabet (they'll probably start some new variant naming scheme for this if it goes beyond Z) but geez. If yaha.(insert letter here) is that effective, why? Lack of AV usage/updating?

    Adoy:
    can I call you undies?
    I think we can make that nice little nick stick can't we chaps.....

    Steve:
    Or am I missing the point?
    Quite possibly......

    Ms. M:
    Why?
    From my point of view I have seen relatively few infected files from the Yaha family being stopped at the mailserver. I think that this, coupled with the fact that it doesn't make a huge "splash" on the internet like MSBlast has kept it below the media's radar and, as a result, it has kind of "stealthed" it's way along without being noticed taking advantage of the "usual suspects".
    Don\'t SYN us.... We\'ll SYN you.....

    HAven't seen Yaha in the workshop for a 3 or so months.. Had most problems early in the year.. The info from Sophos was only one reported case.. now that could mean the only one .. or it could be the first of many.. who knows..

    And as for a new nick.. you won't want me dirty would you..lol


    Cheers..


    BTW.. Sobig.G .. to mention a succesful strain of Virii/worm something tells me we need to be prepared now.. it may be soon.. or I am paranoid..
