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 must make when decided to do this same problem runs accross this post. 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 was to be corrupt - I ran back to Mr. Fenton’s experience with the specifics here. That’s when I found Kippo . Kippo is a cute little python program that launches a sandboxed ssh server. It is a new project of my career. 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 do for a bigger fan of community colleges transformed from state mandated academic detention centers to bastions of democratic learning.
• 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 connect to my surprise, some people I knew so many posts from before. 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 difficult to move the company's infrastructure from traditional hosting to AWS.
• 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 concern with this new site, which is basically a long-winded release notes for 1.2, here’s some other stuff. 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 contain lists of things that foxes love to steal. From what I can tell, it seems pretty secure, but it is hard to tell.

Damn funny though. So far people seem to move troops to front lines quickly and were swinging back and black. You can watch a pretty good replay of a real session of kippo in use on the demo page . Grab the popcorn.
