## Solution
1. SSH into the target with the password `hitconctf`
```
ssh [email protected]
```
2. Type everyone's favourite comfort command `ls` and admire the cute ACSII [steam locomotive](https://github.com/mtoyoda/sl) normally associated with `sl`:

```
3. "Reverse" `ls` as `sl`
```bash
$ sl
flag
```
4. Ah, the flag is in the file `flag`. Read it with `cat` (backwards, obviously):
```
$ tac galf
hitcon{!0202 ftcnoctih ot emoclew}
$ Connection to 18.176.232.130 closed.
```
