Honeypot as a service

HaaS logoI’m currently working at CZ.NIC, Czech domain registry on project Turris which are awesome open source WiFI (or WiFi free) routers. For those we developed quite some interesting features. One of them is honeypot that you don’t run on your own hardware (what if somebody managed to escape) but you basically do man in the middle on the attacker and forward him to the honeypot we are running behind many firewalls. We had this option for quite some time on our routers. But because plenty of people around the world found the idea really interesting and wanted to join, this part of our project got separated, has its own team of developers and maintainers and you can now join with your own server as well! And to make it super easy, packages are available in Tumbleweed already and also in security repo where they are being build for Leap as well.

How to get started, how it works and what will you get when you join? First step is register on HaaS website. You can also find there explanation what HaaS actually is. When you log in, you can create a new computer and generate a token for it. Once you have a token, it’s time to setup software on your server.

Second step would be obviously to install the software. Given you are using the cool Linux distribution openSUSE Tumbleweed it is pretty easy. Just zypper in haas-proxy.

Last step is configuration. You need to either disable or mive to different port your real ssh. You can do so easily in /etc/ssh/sshd_config, look for Port option and change it from 22 to some other fancy number. Don’t forget to open that port on firewall as well. After calling systemctl restart sshd you should be able to ssh on new port and your port 22 should be free.

Now do you still remember the token you generated on HaaS website? You need to enter it into /etc/haas-proxy, option TOKEN. And that’s all, call systemctl enable haas-proxy and systemctl start haas-proxy and the trap is set and all you need to do is wait for your victims to fall in.

Once they do (if you have public ipv4 than you should have plenty after just a day), you can go to HaaS website again and browse through the logs of trapped visitors or even view some statistics like which country attacks you the most!

Anonymized data from those honeypot sessions are later available to download and CZ.NIC has some security researchers from CSIRT team working on those, so you are having fun, don’t compromise your own security and helping the world at once! So win,win,win situation 🙂
