I don't think that discussion on hacking are on topic...

But for information, hacking doesn't include only gaining
access to another computer. That include also other
type of computer piracy including the misuse of security
bugs and features like the one used recently.

Oh, and that has nothing to do with mailbombing. It was
a "denial of service" type of attack. It's based on
the 3-way hand-shaking of the TCP/IP protocol.
Normaly, when a computer connect to another, it sent
a request (SYN). The other computer confirm with
his own request (SYN/ACK). Finaly the first computer
acknowledge the server (ACK) and then the connection
is established.
Between steps 2 and 3), the server pool the request,
hoping to be able to serve the connection soon enough.

With a "denial of service" attack, the first computer
ask for a lot of connection but never achnowledge the
server. So the server is forced to pool all those
request without being able to know which ones are legitimate
and which one should be discarded.

Original, most systems were able to pool only 5 requests
at the same time. (TCP/IP was supposed to be on a local
LAN with nearly no delay :)

Now, I think that all is said on that subject...
