That showed up on this list once before
(http://groups.google.com/groups?q=icmp+please+help+matrix+catch+me&hl=e
n&lr=&ie=UTF-8&oe=UTF-8&selm=I5u_a.85213%247O4.1995953%40twister.rdc-kc.
rr.com&rnum=1) and also on the comp.security.misc newsgroup
(http://groups.google.com/groups?q=icmp+please+help+matrix+catch+me&hl=e
n&lr=&ie=UTF-8&oe=UTF-8&selm=aa34f8a6.0307300004.60fadc8d%40posting.goog
le.com&rnum=4).  I didn't remember but google did;)

What that traffic originating from one of your boxes or coming in?  I'd
give the related box a serious check.  First thought was a back door but
then the question is, "Why be so obvious?"  How long a period of time
did this traffic involve?  Is it still going on?

Subject: [Snort-users] Icmp Ping


Hi,

I was looking at ACID's report for the first time this month
and noticed the extraordinary amount of ICMP PINGs.  I took
a look at one, and was surprised to find the following as
the payload:

000 : 50 6C 65 61 73 65 20 68 65 6C 70 20 6D 65 2C 20   Please help me,
010 : 6D 61 74 72 69 78 20 63 61 74 63 68 20 6D 65 20   matrix catch me

That Can't be a ping.

Can someone point out whether or not I fuzzed up my
snort configuration?

Thanks.

Edmund
