View the exercise here: [PentesterLab: Recon 01](https://pentesterlab.com/exercises/recon_01/course)

### **OBJECTIVE**

For this challenge, your goal is to generate a 404/"Not Found" error on the main website for **hackycorp.com**.

### **THE 404 PAGES**

Not Found/404 pages can leak information about the web stack used by a company or application. It also allows you to detect files that exist when you start brute-forcing the directory. This is why it is important to check what the 404 page looks like.

### **SOLUTION**

To get a 404 Error Page, append any random string after `hackycorp.com`

{% hint style="success" %}
In this screenshot, we entered **`hackycorp.com/random`** to get the key to this challenge, but you can also input any gibberish string to achieve this. 
{% endhint %}
