It's because people are being very closed mouthed with this, the corps
either have no idea what is going on or do not wish to share what they
know, and those involved with the attacks have done a good job of keeping
silent. Besides comparing Morris's worm to what is going on now is hardly
fair, the net was a very different place then, and his cpu cycle hog of a
program was alot easier to deal with and detect.

Has anyone else noticed the dearth of technical information about these
attacks?  Although some of the largest web sites, and networks have been
hit, I still haven't read a confirmed description of exactly what is
happening.

Its been three days.  After the Morris Worm, by this point in time I had
seen several technical descriptions and even portions of decompiled code.
And I was just an interested Internet user in those days.

In this case I still haven't seen confirmation if it was trino, tfn, something
new, or what.  Or even confirmation if it was a series of HTTP GETs or random
packets, or some interesting corruption of a packet.  Or if confirmation the
attacks are coming from the same set of hosts or different ones for each attack.
If it is the same set of IP addresses, could we RBL (or create a new RBL) them?

Maybe I'm just on the wrong mailing lists.
