INSTALLATION

	The ../bin/ directory contains statically compiled 32-bit and 64-bit Linux binaries. If you wish to compile 
	from source, run:

		$ make
		$ make install

	This will build Rebind and its dependencies and copy the resulting binary to the ../bin/ directory.

GENERAL DESCRIPTION AND OVERVIEW

	Rebind is a tool used to implement the "multiple A record" DNS rebinding attack. It can be used to rebind a
	given domain name to any public IP address. This can be used to proxy attacks through a client's browser
	to publicly accessible Web sites, as well as to the internal Web interface of many home routers.

	In order to achieve this, Rebind provides several different services/features:

		1) A DNS server that handles all DNS lookups for the given domain, as specified on the command line. 
		   The DNS server code can be found in dns.c.

		2) An attack Web server that is used to identify the requesting client's public IP address (unless
		   an explicit target list was specified on the command line) then redirect the client to a randomly
		   generated sub-domain of the given domain. It then updates the DNS server's database with the random
		   sub-domain and the client's public IP address. It also provides the requesting client the necessary
		   JavaScript code to turn the client's browser into an HTTP proxy, and tells the firewall (iptables)
		   when to block what IP addresses. The attack Web server code can be found in attack.c.

		3) JavaScript code that is returned to the client's Web browser that is used to complete the rebinding
		   attack and subsequently proxy the attacker's HTTP requests to the rebound IP address. This JavaScript
		   code can be found in www/payload.html.

		4) A callback Web server that is used to handle callbacks from the JavaScript code. This will tell the
		   JavaScript code what requests it needs to make to the rebound (aka, target) IP address, and will handle
		   the data returned from that request. The callback Web server code can be found in callback.c.

		5) An HTTP proxy server used by the attacker's Web browser. This proxy server provides a simple Web interface
		   which displays all active clients, and allows the attacker to browse the Web sites hosted on the target IP
		   address(es) via those client's browsers. The proxy server code can be found in proxy.c. The Web interface
		   code can be found in www/index.html.

		6) A configurable firewall so that clients can be blocked at the attack port (port 80 by default) at the
		   appropriate time. Rebind does not provide its own firewall, but merely interfaces with iptables. This code
		   can be found in iptables.c.
	
		7) A command-line interface to view/change the status of Rebind. This takes the form of a custom command shell
		   with tab-completion, command history, etc. This code can be found in console.c.

	Other files not listed above serve as support code to these primary functions, and consist mainly of function wrappers 
	for things like IPC, database queries and network/socket transactions.

KNOWN BUGS

	o Rebind shell commands that accept parameters do not handle values with whitespace in them.
	o If you set a cookie that has an un-escaped double-quote in it, it will cause a JavaScript error in the client browser.
