RE: UDP 1434

>From what I have seen in the past 169.254.X.X is your IP. It is an
non-routable ip given by windows to dhcp clients that cant grab a DHCP
address. It is possible for a NIC to have more than on IP, this might be
the case here. From that dump it looks like you have a infected
computer.

Hi,

 Internet traffic of  INDIA's and ASIA's network has been effected
badly.....its amazing....seriously microsoft sucks..  but its fun !! :-)

Well i found something new in this ... i think this worm spoofs IP
address according ....below is the tcpdump output ..out which the host
is ....169.254.198.47. sending repeated packets to different network...
but...169.254.198.47..is not our network....after matching th MAC
address ..it was orginating ...from our IP i.e 202.71.129.197..

tcpdump output :

20:56:28.016820 0:2:b3:2f:a4:95 1:0:5e:2d:b2:12 ip 418:
