[Snort-users] Shut them down, I have had enough...

if I could drop the packets at the ISP end, then that'd be great,, I can't
they don't offer that..

unfortunatly, my ISP just emailed me to tell me that they are infected as
well...

if I drop them or not at my end.., they still chew bandwidth...

(I am getting about 100 or more attempts a minute.. and it would be more
except my bandwith is low)

Also, I think I could defend myself against them,, we have good lawyers, and
besides, we were responding to an attack from them,, we didn't go lookin and
we object to being attacked by their server...

if someone comes to your house with a gun and tries to shoot you, and you
shoot them instead,, thats a case for self defence...

emailing them doesn't work... been there done that..
if they don't learn, how can we stop them??? the net is so slow over here at
the moment, and its mostly caused by shitloads of windows boxs...

Why don't you just set your firewall to drop all packets coming from that or
those ip addresses?  Remember, if you send a DDos to that or those servers,
you are just as guilty as those administrators of not doing due diligence.
Depending on the damage and downtime associated with your proposed DDos, YOU
can be held liable.  I don't think your company would like that too much!

Hi all,

I have seen in the past a php script that would shut down infected IIS
servers that are trying to infect linux box's

I havn't done it, because I didn't really think it was that nice a thing to
do...

This is the one I saw...

> >
> > 2) Then in your httpd.conf or similar... add this
> >
> > AddType text/html .ida
> > AddHandler server-parsed .ida

but I checked my personal server this morning and the httpd error log looks
like this. (see the end of the email)

anyway, I'd like to setup the server to shutdown any IIS box that asks for
cmd.exe or root.exe

Does anyone know how this can be done using either perl or php???

has anyone already done it? if so where can I find it???

I am tired of this, I have a very limited bandwidth, and even if it isn't
doing any damage, its chewing up the bandwidth.. and costing me money, as
far as I am now concerned, they have three choices, either patch their
server, pay my bandwidth bill, or get their servers shut down alot...

Any help would be much appreciated.

Regards
