# Hack the Jail - Part 1 

## Difficulty

Very easy, but the participant needs to know about "sudo", which might be unknown for Linux novices.

## How To Solve

![](https://imgs.xkcd.com/comics/sandwich.png)

If something says "permission denied" on Linux, try with `sudo`. In this case the `/etc/sudoers` file seems to contain a peculiar line related to the currently executing user `ig`.  It states the following:

```
ig ALL = NOPASSWD: /bin/cat
```

This means that the `ig` user is allowed to execute the `/bin/cat` binary with elavated permissions without using a password.

Therefore executing: 

``` 
sudo cat /flag.txt
``` 

reveals the flag.
