Hi all,
I am wondering if anyone has seen a large DDoS before, specifically on
port 80 UDP with data that seems to be relating to Call of Duty 4. I did
a quick packet capture, and the payload looks like this:

As far as I know CoD 4 doesn't use port 80 UDP, and I can't see anything
else that would. The box doesn't have anything listening for port 80/udp
(it does run a web server) and never has.
Has anyone seen similar traffic before? I am struggling to figure out
what is causing this traffic, or if its existing traffic being replayed
to try and avoid filters.
Thanks
