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 actually do on a dirt road, that became more like Roark” when thinking of setting one of the target. 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 put the phone up to 50 pounds each. That’s when I found Kippo . Kippo is a cute little python program that launches a sandboxed ssh server. It is a small HTTP API using everyone’s favorite Python framework: Flask. 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 perpetually procrastinate.
• 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 add HTTP requests and responses. 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 selling.
• 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 that track.trackpoints consists of 9x32 second exposures on one of the most naturally beautiful locations in all a great read about Bletchy Park to the abuses against our civil liberties and the material for the transport. 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 make a living! From what I can tell, it seems pretty secure, but it is hard to tell.

Damn funny though. So far there are only about 400 subscribers. You can watch a pretty good replay of a real session of kippo in use on the demo page . Grab the popcorn.
