Wetland

Wetland is a high interaction SSH honeypot，designed to log brute force attacks.What's more, wetland will log shell、scp、sftp、exec-command、direct-forward、reverse-forward interation performded by the attacker.

Wetland is based on python ssh module paramiko. And wetland runs as a multi-threading tcp server using SocketServer.

Features

• Use docker to provide a real linux environment.
• All the password auth will redirect to docker.
• All the command will execute on docker.
• Save a copy of file when hacker uploads some files with SFTP.
• Extract and Save files from exec-log when hacker uoloads some files with SCP.
• Providing a playlog script to replay the [shell | exec | direct-forward | reverse-forward] kind of log.
• Advanced networking feature to spoof attackers IP address between wetland and docker(thanks to honssh)
• Kinds of ways to report to you when wetland is touching by hacker, but now only email and bearychat.

Requirements

• A linux system (tested on ubuntu)
• sshd images in docker (e.g rastasheep/ubuntu-sshd)
• python2.7
• paramiko
• yagmail
• IPy
• requests

Setup and Configuration

1. Copy wetland.cfg.default to wetland.cfg
2. Generate keys used by ssh server

• run mkdir data
• run ssh-keygen -t rsa, and put them in data/
• run ssh-keygen -t dsa, and put them in data/
• Remember that Wetland and sshd container should use the same keys.

3. Install python requirements

• run pip install -r requirements

4. Configure the banner of ssh server

• Edit banner in wetland.cfg
• It should be same with the ssh banner of sshd contaniner

5. Or you can run python util/initwetland.py ./，this script will do all the work above
6. Configure the output plugins in wetland.cfg

• enable or disable in [output] section
• Edit the url of incoming robots when using bearychat
• Edit user、pwd... when using email

6. Install p0f if you want

• run git clone https://github.com/p0f/p0f
• run cd p0f
• run ./build.sh
• Edit [p0fp0f] section in wetland.cfg
• if you dont need p0f, just disable p0f in [output] section

7. Install docker

• install docker with docs in www.docker.com
• run docker search sshd, then choose a image running sshd
• run docker run -d --name sshd sshd_image_name
• run docker inspect sshd, then edit docker ip address and port in wetland.cfg
• sshd's ssh port should be same with wetland's
• delete and replace sshd container sometimes if you want

Running

1. Run

• run nohup python main.py &

2. Stop

• run netstat -autpn | grep 22
• then kill pid_number
• ahaha

3. Clean

• Maybe you should delete some iface created by networking module by hand.
• run ip link list
• then ip link del dev wdxxxxxx
• finally clean up the nat table of iptables or just reboot

4. View logs

• run python util/clearlog.py -p log will remove logs that only have pwd.log, and username:password will write into -l file, default ./pwd.txt
• then use playlog.py in util

5. file system changes

• filechange.py will copy the read-write layer of the sshd container to ./ , the layer includes that hacker create and remove
• e.g. docker inspect sshd --format '{{.Id}}' | python filechange.py -

Dockerized wetland

• run docker pull ohmyadd/wetland
• see it in docker hub

TODO

• wetland dockerized

• create sshd docker image realistic

• automate create sshd container

• add watchdog

• take use of bearychat incoming outgoing

• distribute log system & support hpfeeds
