PHP-HTTP-Tarpit

===============

Confuse and waste bot scanners time. 

Url rewrite unwanted bot traffic to the la_brea.php file. It is important you use Url rewrites not redirects as most bots ignore location headers.

Based on research done by Chris John Riley. http://github.com/ChrisJohnRiley/

Defense Techinques Implemented

------------------------------

* Blinding Mode

	* Return 200 Founds for all requests.

	* Outputs random alphanumeric content to client.

		* Special phrases and characters injected into the content.

	* Increases amount of false positives in scanners' results.

* Ninja Mode

	* Return 404 Not Founds for all requests.

	* Sometimes outputs random content as described above.

	* Increases amount of negatives in scanners' results.

* HTTP Tarpit

	* Returns a 101, 102, 103, or 401 for all requests.

	* Generates long response wait times to client.

	* Wastes time of scanners.

* Chained Redirection

	* Returns a 301, 302, or 307 for all requests.

	* Redirects to a randomly generated url many times in succession.

	* Wastes time of scanners.

	* Punishes bad web crawlers for not respecting the robots.txt. Looking at you Baidu.

	* Sometimes ends in Bounceback Redirection (see below).

* Bounceback Redirection

	* Returns a 301, 302, or 307 for all requests.

	* Redirects request back to requesting ip on common http/https ports.

	* Wastes time of scanners.

	* Could potentially tie up resources on attackers edge node.

* Random Defense Selection 

	* For each request

	* By the minute

		* By the minute is very effective in baiting the bots and by not looking too random or predictable.

Wishlist

--------

* ~~Robots.txt file emulation to not punish good web crawlers.~~

	* This is handled better by hosting an actual robots.txt and creating an exemption in the url rewrite to allow access to it.

* Support for dumping contents of random files in a folder for the Blinding Mode defense.

Wordpress Implementation

------------------------

I have implemented this tarpit script into a Wordpress security plugin here to help with brute force attacks:
