Hello all,
It looks like someone hacked my apache2 server and I am trying to understand
how this could have happened.
This is what happened:
All of a sudden the server - in response to a web-browser request for a page
- started to give a full screen of unknown characters (looked like a long
text with encoding mismatch).
The output was immediate and the same for all the web-sites located on the
server.
Looking at the page source of the output I see the following:

==================
The address indicated in the begining of the page code leads to some chinese
server.
So, somehow it happened that the output of the apache server was substituted
by this page, which redirected visitors to some chinese server.
But the most strange thing was that the problem dissapeared itself! So, it
last for 10 minutes then disappeared! And the again started and again
dissapeared. Finally, I turned down apache untill I understand what is going
on...
Any idea how could that happen? How to reproduce this? How to prevent?
Where to look for logs? I have check both ssh logs and apache logs, there is
nothing that could seem unusual there...
Any help is appreciated.
Oleg.
Oleg,Are you running any sort of MySQL Database on this machine, and if so is it patched and fully updated along with any php scripts. What you are showing us is indicative of a SQL Injection Attack.
Shocked no one has mentioned especially with the rampant incline of the Russian Business Network to spread its malware through the use of SQL Injection on any vulnerable website.
Thanks,Daniel
