Honeypots

Hi all,

Thanks for the many responses I received on this thread.
Thanks Antonio, Jesper, Noah, Dharm for some valuable suggestions including

1. redirection of some common TCP/UDP ports
2. MAC spoofing
3. client honeypot setup

Well I plan to begin with initial client honeypot set up and observe the results. The statistics of an un-patched windows machine getting infected was an interesting one.
I also plan to move on to some different architectural possibilities.

In this regard I also wanted to discuss whether there are any public experiments in Intenret community in area of Honeypot with which I can link up from home using my dialup connection and carry out my research and analysis. I have heard about overlay networks and network testbeds. Are there any specific for honeypots as such??

Regards,
Mayank

Hello mayank ,
                     According to my understanding the scenario which you are assuming need to have access to DSL or to the Proxy so that the external traffic can be forwarded to the internal address.
OR if you dont have the access to the proxy or dsl router , in this case  you can try 

1.MAC spoofing of the Public Interface ( so that outgoing traffic can be captured )
2.Dynamic IP address wont make any difference as once compromised it will be traced by the attacker for further move .
3. In case you still feel to have a honeypot having public interface , then you really have to ask ISP to give you a static one.

Hi Mayank.

Assuming you have the follwiong setup:

dsl line without static IP to home/soho office, a honeypot behind the dsl-router (with builtin firewall function), and you can put the Honeyd on a fixed internal IP address.

Then you can do the following simple honeypot.

Redirect one of more common TCP and UDP ports to the honeyport and see what random network scannings happens on your firewalls external IP.

The Average time to infect for a an unpatched Windows XP machine is about 15 minutes, this means that you should see traffic on RPC ports, netbios ports etc. you can also open SMTP for some open relay probing, port 80 for CGI attacks, etc.

Hi,

I am writing this email to know some of your valuable suggestions as to
how we can use honeypot in a restricted environment.

Suppose if I want to install a honeypot in an environment where it
cannot get a public facing IP but the machine o which honeypot is to be
installed has an access to Internet
       1. via another proxy or
       2. via a DSL hub

Also, the machine does not have a static IP.

Now in this kind of environment I foresee that the honeypot client will
not be able to receive Internet traffic (including scan or attack or
other malicious binaries propagating..).
It maybe possible that we receive only broadcast traffic being forwarded
through the gateway.

Now, according to us, this is a very limited setup as demanded in a
normal honeypot setup. Does anyone still feel we can use our honeypot
for any other better purpose? Are there any other architectural solution
available to use honeypot concept although not having a static IP and
not visible on the Internet directly?

Any help/discussion on the same is most welcome.

Thanks & Regards,
Mayank
