Can anyone else confirm this? Incidents.org is reporting an increase in port 53 traffic over the last two days. Are we looking at the precursor to the next worm? 216.127.92.38 69.57.146.14 69.57.147.175 Are these entries coming in the DHCP packets or are they being set *after* DHCP is complete? Are compromised systems acting like DHCP servers stuffing their own DNS entries into specially crafted replies? Can you post traffic dumps?
