Security Incidents: RE: HTTP attack looking for /sumthin ?

["Beckett, Josh" <JBeckett () enviance com>]

My first thought on this was a Bot or spider, but after running the
source IP's through the ol' whois routine, I came up with one sourced
out of a UK ISP and the other from a University.

I'd agree with one of the previous statement's that it's some sort of
scanner/recon tool looking for error codes and server vulns.

I have seen this on our servers, starting Oct 12 with 213.165.144.xxx 
(only one ip) and then again on the 15th from 194.236.60.xxx (also one 
ip) .

Each time they hit they sent 5 to 6 attempts within one second, all 
looking in the same place.

213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0"

404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0"

404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0"

404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0"

404 1086 "-" "-"
213.165.144.xxx - - [12/Oct/2002:05:40:01 -0500] "GET /sumthin HTTP/1.0"

404 1086 "-" "-"
(6 times in all.)

All logs look identical to your post.
What do we have here ?

cheers,
cory
