If we browse to a website, we are presented with the following form :
```html<form action="button1.php" method="POST">    <input type="submit" value="PUSH ME! I am your only hope!"/></form>```
Clicking the button takes us to a second page than has another button - thistime a link :
```htmlButton2```
If we click the second button, we are shown an error :
```html<form action="button2.php" method="POST">    FORM DISABLED. THIS INCIDENT HAS BEEN LOGGED AND REPORTED TO /dev/null                  </form>```
Now the hint was to look at the difference between the two buttons.
1. The first button was form pointing to `button1.php` with a `POST` method2. The second button was a link, meaning clicking it send a `GET` request3. In the error page there is a form that points to `button2.php` with a `POST` method
This seems to indicate that we should try sending a `POST` requests to`button2.php` (I used [Burp Suite](https://portswigger.net/burp)'s proxy andrepeater for tha). And indeed when we do, we are given the flag :`picoCTF{button_button_whose_got_the_button_dfe8b73c}`.
