[nznog] ICMP and port 80 traffic

Hi All Is anyone else seeing a massive increase in ICMP and traffic to port 80? I started noticing this last night on one of my subnets that is mostly unused, just a huge amount of packets to random addresses. It's still going flat tack.. I've grabbed a quick packet dump if any of you want to see what I mean - it's in tcpdump format. http://blair.wise.net.nz/~blair/icmpandport80.gz Is this some worm variant that nobody's figured out yet?
