Re: Private routes advertised

We are seing long SMURF attack against the address 193.124.51.206. I ask 
everyone who read this list and can check traffic over his network to 
check if he see ICMP packets FROM 193.124.51.206 (SRC address) TO 
129.72/16, 129.74/16 etc...

I don't think it's impossible to localise the intruder if he hold this 
crazy program for so long (more than 6 hours). All it's nessesary to 
trace is the frauded packets with the SRC address 193.124.51.206/32 and 
DST addresses from the black list described here a few days ago.

What does we seen now is:


Apr 16 20:31:49 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
130.34.195.1 -> 193.124.51.206 (0/0), 1 packet
Apr 16 20:31:50 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
129.115.201.88 -> 193.124.51.206 (0/0), 1 packet
Apr 16 20:31:51 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
129.74.90.51 -> 193.124.51.206 (0/0), 1 packet
Apr 16 20:31:52 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
129.72.4.38 -> 193.124.51.206 (0/0), 1 packet
Apr 16 20:31:53 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
134.57.7.220 -> 193.124.51.206 (0/0), 1 packet
Apr 16 20:31:54 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
128.139.221.1 -> 193.124.51.206 (0/0), 1 packet
Apr 16 20:31:55 MSK: %SEC-6-IPACCESSLOGDP: list 108 denied icmp 
148.81.230.253 -> 193.

etc etc... This is echo-reply packets, and this means there exists 
ECHO-REQUEST packets sended by intruder.
