Subject: [Snort-sigs] Strange CyberKit alert activity

Anyone seeing strange ICMP PING CyberKit alert activity today.  Starting
about 6:00 AM this morning we started getting a large number (6000 + during
the past hour) of these alerts from various source IP's to various
destination IP's.  

Here a snip from the attack summary - basically the summary continued
through the 207.172.X.X into the 207.173.X.X and this appears to be growing
as I just checked and am seeing new alerts from the 207.175.X.X address
space for this client.  I am also seeing these alerts on another clients
network on a much broader distribution of single alerts.
