Firewall Wizards: Re: New Script Kiddie tool ?

["H. Morrow Long" <morrow.long () yale edu>]

208.184.139.82 is 208.184.139.82.speedera.com
208.185.54.14 is 208.185.54.14.speedera.com

Speedera (www.speedera.com) is a streaming content delivery company.

I noticed that Snort added a new signature recently (in the last year)
called the 'speedera ping'.

It would appear that Speedera may be trying to gauge the QoS RTT between
one of their streaming servers and an endpoint by using the ICMP Echo
packets.

The Snort rule from the std snort db is:

icmp.rules:alert icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"ICMP PING speedera"; content: "|3839 3a3b 3c3d 3e3f|"; 
depth: 100; itype: 8;  sid:480;  classtype:misc-activity; rev:2;)
