CTFshell 1.0.0

Client CLI for the Cryptotronix CTF server.

Summary

If you don’t want to have to deal with the REST API of our CTF server, this executable will wrap all of the requests in a simple and easy-to-use CLI.

Usage

To register on the server use the ‘register’ command, providing a maximum 32 character username.

> register example_user
success!
user uuid: dae72401-b760-43e0-a188-d45556f0a7ff
saved.
>

To view the flags use the ‘flags’ command.

> flags
+------+-----------------------------+--------+
| name |         description         | points |
+======+=============================+========+
| 1.1  | This is a description.      | 5      |
+------+-----------------------------+--------+
| 1.2  | This is also a description. | 1      |
+------+-----------------------------+--------+

To submit answers to the server use the ‘submit’ command, providing the flag you are attempting to solve and your answer.

> submit 1.1 hello
world! good job!

To view the leaderboard use the ‘leaderboard’ command. Note, you will not appear on the leaderboard until you have at least one point.

> leaderboard
+----------------+--------+
|      user      | points |
+================+========+
| master         | 42     |
| rival          | 6      |
| example_user   | 5      |
+----------------+--------+

To ask for hints use the ‘hintbot’ command. He’s pretty lazy so he might not be awake at the start of the game. Send him the name of a flag to ask for a hint, or just chat with him.

> hintbot Can I have some help with 2.2?
Have you tried giving the correct answer?

If you want to use an already created user use the ‘set_user’ command and provide a user’s uuid.

> set_user 0786c22d-4ad1-4430-8505-ecd3d00194b2

If you need to change the server hostname from what you are about to provide, use the ‘set_hostname’ command.

> set_hostname ctf.challenge.com

State

This shell uses a sqlite database to save state and settings. This database will be created at ./.CTFshell.db by default, but can be given a custom path using CTFshell -d [path].
