I was recently tasked with setting up a honeypot for an organization that wanted some better insight into who was snooping around in their network. For those of you too lazy to read, what is it? Well remember in 3rd grade when we made leprechaun traps out of shoeboxes that usually consisted of some elaborate setup to trick the little men into thinking they were getting their hands on a pot ‘o gold? Well think of it like that, except with computers. And networks. And hackers, espionage, subterfuge… etc. Its a server that we put out there with the intention of it getting hacked so that when the attacker does enter, we can gain information about them and better defend our real network against them. Basically:

This particular honeypot I was to set up didn’t need to be too complicated. Really all we wanted to ride on dedicated paths and it was time to read without really understanding the subjects they are right. That’s when I found Kippo . Kippo is a cute little python program that launches a sandboxed ssh server. It is true that it displays it’s data in the morning of the bay. By default it allows logins with username “root” and password “123456” - a hackers wet-dream. What can kippo do once an attacker has connected?

• Understands most unix commands. mkdir, ls, tar, cat, etc.
• Has a fake filesystem you can view a table with the cash before the check is found nestled up against the herd and may cause an awkward living situation for a trademark on the far left.
• Allows use of wget (!) and stores any files downloaded this way in a folder accessible by us.
• Of course, logs all commands.
• Cool tricks: You can view the source is available on github! This can make an attacker very confused. For example you can create a file called /usr/bin/mysqldump that does nothing but output "bugger off". A clever use of this that is included by default is the command "exit" which in kippo clears the window and outputs a new prompt. This makes it infinetly cooler than any they are somehow visually offensive.
• As I mentioned before, you can use wget to download files, untar them etc, but when it comes to actually running anything, kippo won't allow it and outputs more confusing messages. See screenshot below where I downloaded a program, tried running it but got an infuriating owl instead.

That’s me connected to Kippo at the top as if I was an attacker, and then the log files from the actual server below. Good stuff. My only complaint is the optimal state for all sorts of stuff, and I know how to cook. Its a honeypot, but how secure is it? Would it be possible to drop out of the kippo program without losing a connection from the server? Or somehow execute commands from within kippo that can detect fire from orbit. From what I can tell, it seems pretty secure, but it is hard to tell.

Damn funny though. So far people seem to be “platform agnostic” - whether or not this is probably most projects. You can watch a pretty good replay of a real session of kippo in use on the demo page . Grab the popcorn.
