Investigation is still ongoing, but from what they can tell, majority of
the attempted connections have been going over TCP port 22.

Did you run a sniffer to get an idea of what all the traffic is?
Curious what, if any, port(s) are being flooded.

We had several machines start spewing huge amounts of data causing our
pipe to the public Internet to stop.  We had no traffic coming in or out
of the campus.  We're unsure of whether it's virus related, but wanted
to inquire if anyone else has heard of or came across something similar.
It appears to be an DDOS attack, but, originating from the inside.  This
started last night at about 10pm EST.
