# netrunner - [WEB] Challenge Santhacklaus

netrunner is a Web challenge proposed in three parts during the **Santhacklaus CTF**. This online event, _santhacklaus.xyz_, was a four students project from IMT Lille Douai (Telecom Lille). This Capture The Flag in jeopardy style lasted one week (14 to 21 December 2018) and gathered more than 400 participants.

## Getting Started

### Prerequisites

To use this project, you need to install [Docker](https://docs.docker.com/install/) and [Docker-Compose](https://docs.docker.com/compose/install/).

### Configuration

You probably need to change the listening port in `docker-compose.yml` file to avoid conflict with other softwares, like another Web server.

```
...
ports:
    - "<chosen_port>:80"
...
```

### Running

Move into the root repository, then, build and start all the containers with this following command:

```bash
docker-compose up -d
```

Now, you can access to the first part of this challenge at localhost:<chosen_port> and others parts at localhost:2077.

That's all! 😉

## Online version

You can find a online version of this project on [CTF;space](https://challenges.deldel.fr) platform.


## During and after the CTF

### Part 1

#### Statement

> V, I got a mission for you!

> We discoved a Netrunner who hack neural implants to create false memories. We spotted the target's interface on the Net at this address: http://IP

> Find out who he is and a way to stop him.

### Part 2

#### Statement

> Nice V! I owe you one!

> But before we go to visit him, I would like to have a means of pressure. Here is his maintenance access: IP:PORT

> See what you can do and let me know.

#### Hint

> He seems to have a “ghost” in the shell

### Part 3

#### Statement

> You doing great!

> But this access is not enough. See if you can get privileged access, the same used by Zetatech technician for maintenance.

> It will allow us to unplug it in case of a glitch.
