Worms - What are the trends?

[Ondrej Krajicek <krajicek () ics muni cz>]

Hello all,

first of all, I am not a virus/worm researcher, so please accept
my apologies for any stupid questions beforehand.

I tried googling on Sasser and other recent worms, particularly
about the timing and statistics of their appereance,
expansion (how many machines were affected in how long), 
reaction time of anti-virus companies etc., with
no success.

I've heard/read that Sasser worm appeared only eight hours after
the patch for the vulnerability has been released, but
was not able to confirm that. Is this true? How long will it
take before we will see truly 0day worms in the wild? (Any
estimates?)

Thanks for any information or references.

Ondra
