PHP-HTTP-Tarpit is a tool designed to confuse and trap misbeheaving webspiders. It accomplishes this task through a combination of log fuzzing, and error spoofing.
Here's what you need to do in order to deploy the tarpit on your webapp. First you need to copy the file la_brea.php into a folder accessible to the clients of your web application. Next, Simply include a hidden reference to this page inside some portion of your application. This reference should be hidden so that no users accidentally stumble onto it. Something like a hidden link would be perfect. Something a web spider would want to check out.
Once you've done these two steps. You're golden.
Example 1: Deployment
To get started, for our example we will copy the tarpit into the web root of out web application.
sudo cp /opt/PHP-HTTP-Tarpit/la_brea.php /var/www/
Next we want to insert a reference into some portion of your web application that points to this file. For example, we might edit your application's index.php appending this line:
<a href="/la_brea.php" ></a>
You may also want to chown the file to be owned by the web user.
sudo chown www-data:www-data /var/www/la_brea.php
It's that easy.
