Hi,
I have a windows 2000 server machine which we use as
both WEB server & FTP server. For past 2 days it has been
generating traffic. It keeps on uploading something, and
consumes all our internet bandwidth. I installed many
fixes and updates, but its of no use. i tried using the
command $netstat -a which showed a lot of established
connections and more than 1000 ports where opened
automatically which were in "LISTENING" state. what should
i do now ? Please help me to sort this issue. please mail
to venkatesh@cgvakindia.com

Uploading what to where? You mention 'fixes and updates' but does that
include Anti-Virus and/or Anti-Spyware?

Ethereal is a great product used to analyse incoming and outgoing network
traffic.

Download it here http://www.ethereal.com/

Do you have a Firewall installed on the network or on this machine. Also,
have you an up to date virus scanner installed.

If you don't have a virus scanner - you should get one. In the mean time you
can perform a free scan here http://housecall.trendmicro.com/

Did you download Ethereal? If you use it you could see where your
network traffic was going and that might give you some clues as to what
is going on. Have you checked to make sure that there are no mystery
programs running on your server?

For future reference you can also use free tools such as TVPView, Process Explorer,
and Autoruns from SysInternals to port to process mappings. process Explorer will
give much more detailed info on processes while Autoruns will startup programs
configured on your computer.

http://www.sysinternals.com/ntw2k/source/tcpview.shtml

You also need to take steps to harden your computer from future problems and a clean
install is the best place to start from but that is your decision. The links below
will be helpful. Be sure to use complex passwords on your server, and use the IIS
Lockdown tool after backing up the server including the System State and the IIS
configuration as you can in the IIS Management Console. --- Steve

In addition to the advice you've already gotten, I recommend you also
consider these steps:

http://securityadmin.info/faq.asp#hacked
http://securityadmin.info/faq.asp#startup
http://securityadmin.info/faq.asp#re-secure
http://securityadmin.info/faq.asp#harden

In particular, PSlist / PStools from www.sysinternals.com and Fport / Vision
from www.foundstone.com/knowledge can tell you what executables are listening
on which ports. Any personal firewall like the free www.kerio.com,
www.sygate.com and www.zonealarm.com will tell you what executable generated
outbound traffic. Ethereal is a great tool especially for advanced users or
where you don't have firewall logs, but these other tools are ones I would
use first.

At this point, you should determine how you were hacked and how to prevent
it from happening again, but after doing that, you might need to consider
whether you should format and reinstall and fully harden the computer after
that, using the instructions above and the info you learned from your
investigation.
