Apologies if this is old news.  It's from Thursday, but I didn't see it
until today.

Symantec comes clean.... Somewhat:

Wow, Symantec is making an amazing claim.  They were able to detect the
slammer worm "hours" before.  Did anyone receive early alerts from
Symantec about the SQL slammer worm hours earlier?  Academics have
estimated the worm spread world-wide, and reached its maximum scanning
rate in less than 10 minutes.

I assume Symantec has some data to back up their claim.

  "For example, the DeepSight Threat Management System discovered the
  Slammer worm hours before it began rapidly propagating. Symantec's
  DeepSight Threat Management System then delivered timely alerts and
  procedures, enabling administrators to protect against the attack
  before their environment was compromised."
