I have a similar packet (but only one) from the same host (time is ntp sync'd 
EST).


Jan 20 12:55:47 firewall kernel: Packet log: input - ppp0 PROTO=17 
67.8.33.179:1 65.83.153.253:1434 L=29 S=0x00 I=20300 F=0x0000 T=110 (#23)

My first worm packet- 

Jan 25 00:32:52 firewall kernel: Packet log: input - ppp0 PROTO=17 
131.128.163.118:1631 65.83.153.253:1434 L=404 S=0x00 I=2610 F=0x0000 T=113 
(#23)

and continued until 

Jan 25 11:48:44 firewall kernel: Packet log: input - ppp0 PROTO=17 
151.99.167.133:30725 65.83.153.253:1434 L=404 S=0x00 I=2 F=0x0000 T=111 (#23) 

when BS.N apparently shutdown 1434.
