PHP function preg_match() error for phishing pages

Recommended Posts

I am creating phishing pages for websites which includes making m.facebook.com for the mobile site and facebook.com for desktop users. Now it works good, but most users don't go to m.facebook.com they go to facebook.com and let php do the redirection for them on mobile sites. Now I got it working mostly. This is my setup. Redirect.php has a line that points facebook to facebookredirect.php. The facebookredirect.php file looks like this

<?php

require_once('mobile_device_detect.php');
mobile_device_detect(true,true,true,true,true,true,true,'facebookmobile.htm','facebook.htm');

?>

That code is from here. The code "mobile_device_detect.php" is for checking if the request for the site is from a mobile web browser or from a desktop which is here

/*

This code is from http://detectmobilebrowsers.mobi/ - please do not republish it without due credit and hyperlink to http://detectmobilebrowsers.mobi/ really, i'd prefer it if it wasn't republished in full as that way it's main source is it's homepage and it's always kept up to date

For help generating the function call visit http://detectmobilebrowsers.mobi/ and use the function generator. If you need serious help with this please drop me an email to andy@andymoore.info with the subject 'DETECTION CODE PAID SUPPORT REUQEST' with a detailed outline of what you need and how I can help and I will get back to you with a proposal for integration.

This code is free to download and use on non-profit websites, if your website makes a profit or you require support using this code please upgrade.

Please upgrade for use on commercial websites http://detectmobilebrowsers.mobi/?volume=49999

To submit a support request please forward your PayPal receipt with your questions to the email address you sent the money to and I will endeavour to get back to you. It might take me a few days but I reply to all support issues with as much helpful info as I can provide. Though really everything is published on the site.

The function has eight parameters that can be passed to it which define the way it handles different scenarios. These paramaters are:

* iPhone - Set to true to treat iPhones as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect iPhones and iPods to.
* Android - Set to true to treat Android handsets as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect Android and Google mobile users to.
* Opera Mini - Set to true to treat Opera Mini like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Opera Mini users to.
* Blackberry - Set to true to treat Blackberry like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Blackberry users to.
* Palm - Set to true to treat Palm OS like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Palm OS users to.
* Windows - Set to true to treat Windows Mobiles like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Windows Mobile users to.
* Mobile Redirect URL - This should be full web address (including http://) of the site (or page) you want to send mobile visitors to. Leaving this blank will make the script return true when it detects a mobile.
* Desktop Redirect URL - This should be full web address (including http://) of the site (or page) you want to send non-mobile visitors to. Leaving this blank will make the script return false when it fails to detect a mobile.

Change Log:

* 25.11.08 - Added Amazon's Kindle to the pipe seperated array
* 27.11.08 - Added support for Blackberry options
* 27.01.09 - Added usage samples & help with PHP in HTML - .zip
* 09.03.09 - Added support for Windows Mobile options
* 09.03.09 - Removed 'ppc;'=>'ppc;', from array to reduce false positives
* 09.03.09 - Added support for Palm OS options
* 09.03.09 - Added sample .htaccess html.html and help.html files to download
* 16.03.09 - Edited sample .htaccess file - now works with GoDaddy
* 14.08.09 - Reduced false positives
* 14.08.09 - Added Palm Pre
* 14.08.09 - Added answer about search engine spiders
* 14.08.09 - Added status variable to report back it's findings for debugging
* 14.08.09 - Added Torch Mobile Iris Browser to Windows Mobile section
* 14.08.09 - Added HTC Touch 3G to Windows Mobile section
* 14.08.09 - Added help links to PHP header and setup PHP in HTML
* 14.08.09 - Added six usage examples
* 15.08.09 - Checked against the list of agents in the WURFL - 99.27% detected!
o 11,489 mobile user agent strings checked
o 99.27% detection rate after a number of small changes
o Those user agent strings listed that are not detected are either robots or too generic for user agent detection
o Any mobiles not detected by their user agent would most likely return true as they'd be detected by the headers they add.
* 20.11.09 - Removed PDA from the piped array to stop false positives
* 22.12.09 - Moved the site to a server hosted at Rackspace
* 23.12.09 - Added support for Mozilla Fennec

* 23.04.10 - Changed all eregi function calls to preg_match
* 23.04.10 - Added two more examples
o Added example-7.php which allows switching between desktop and mobile versions
o Added example-8.php which shows why the script made the decision it did
* No longer using include, using require_once instead

bug fixes with many thanks and much credit to http://www.punchkickinteractive.com/ - thanks Ryan!

The facebookredirect.php says that if it is a mobile web browser go here or if it is a normal page go here. Now it works on my web hosting server but not on the pineapple. The error I get is this

Fatal error: Call to undefined function: preg_match() in /www/ mobile_device_detect.php on line 76

Apparently this function is looking for strings in the browsers User-Agent. The pineapple should be able to run this included function. It is included in php 4 and 5.

If you put these files (click here) in a web directory on a web server like hostgator or dreamhost and go the the facebookredirect.php page and depending on your browser you should go to the correct page. facebookmobile.htm for phones and facebook.htm for desktops. If I could figure out this error and get it working it would be pretty slick for any users that go to facebook.com on the pineapple to seamlessly go to the mobile site for mobile users and the normal site for desktop users.

We don't build in all the PHP mods. The one you will need to install is php-mod-pcre.

Without it you won't be able to match regular expressions.

It looks like php-mod-pcre is not in your pineapple repository. When I run opkg install php-mod-pcre I get this

root@Pineapple:~# opkg install php-mod-pcre
Unknown package 'php-mod-pcre'.
Collected errors:
 * opkg_install_cmd: Cannot install package php-mod-pcre.
root@Pineapple:~#

How do I install this package on the pineapple?

We don't build in all the PHP mods. The one you will need to install is php-mod-pcre.

Without it you won't be able to match regular expressions.

After more research it looks like I have to recompile php. Beginning with PHP 4.2.0 these functions are enabled by default. I guess someone used the --without-pcre-regex when compiling. The pineapple is running php version 4.4.9. Even if I could recompile it I can't find php 4.4.9 source. The only ones I can see is php 5.3, 5.4,5.5. It looks like if I follow this tutorial on phps website here. I can recompile php, but even if I could do that how do I configure it properly for the pineapple and install it? I know that's a lot to ask. By the way why does the pineapple run on such old versions of php?

php4-mod-pcre -- I didn't give a version because I wasn't sure what you were on.

I tried to run opkg install php4-mod-pcre and this is what I get.

root@Pineapple:~# opkg install php4-mod-pcre
Unknown package 'php4-mod-pcre'.
Collected errors:
 * opkg_install_cmd: Cannot install package php4-mod-pcre.

I have another problem. I scrapped that project and started my own php checker that does not use preg_match. The php code is from here that I hacked together. So I have all facebook requests(from the redirect.php file) go to facebookchecker.php and checks if the browser is a mobile one or desktop one which looks like this.

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

if(stripos($ua,'android') !== false){
header('Location: facebookmobile.htm');
exit();
}

if(stripos($ua,'iphone') !== false){
header('Location: facebookmobile.htm');
exit();
}

if(stripos($ua,'Windows Phone') !== false) {
header('Location: facebookmobile.htm');
exit();
}

if(stripos($ua,'windows') !== false) {
header('Location: facebook.htm');
exit();
}

if(stripos($ua,'Opera') !== false) {
header('Location: facebook.htm');
exit();
}
?>

My problem now is that I get this error.

Fatal error: Call to undefined function: stripos() in /www/facebookchecker.php on line 3

It works great on my webhosting server, but not on the pineapple. Whats going on?

Well, yeah. http://www.php.net/manual/en/function.stripos.php

PHP5 only. Use strpos() instead -- make sure to make all string to lowercase before.

Uhhhh, should have seen that. PHP5 only. Anyways the code strtolower() apparently lowers the text of the browsers user agent. I swapped out the stripos with strpos and it works on my server, but still not on the pineapple. This is what my facebookchecker.php looks like now.

<?php

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if(strpos($ua,'linux') !== false){
header('Location: facebookmobile.htm');
exit();
}
if(strpos($ua,'android') !== false){
header('Status: 302 Found');
header('Location: facebookmobile.htm');
exit();
}
if(strpos($ua,'iphone') !== false){
header('Status: 302 Found');
header('Location: facebookmobile.htm');
exit();
}
if(strpos($ua,'Windows Phone') !== false) {
header('Status: 302 Found');
header('Location: facebookmobile.htm');
exit();
}
if(strpos($ua,'windows') !== false) {
header('Status: 302 Found');
header('Location: facebook.htm');
exit();
}
if(strpos($ua,'Opera') !== false) {
header('Status: 302 Found');
header('Location: facebook.htm');
exit();
}
?>

Sorry can't redirect you. Edit the header.

When I test this on my server it works and on my android phone and iphone 4, but when I do this on my pineapple it just stays on the facebookchecker.php page. It displays what I put in the file.

Sorry can't redirect you. Edit the header.

Why does it not redirect? I'm running the firmware version 2.7.7.

EDIT FIXED: I didn't add the "header('Status: 302 Found');" for the if(strpos($ua,'linux') !== false) part. It works now. Yay!

New facebookchecker.php

<?php

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

if(strpos($ua,'linux') !== false){

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'andriod') !== false){

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'iphone') !== false){

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'Windows Phone') !== false) {

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'windows') !== false) {

header('Status: 302 Found');

header('Location: facebook.htm');

exit();

}

if(strpos($ua,'Opera') !== false) {

header('Status: 302 Found');

header('Location: facebook.htm');

exit();

}

?>

Yeah, as I said, always send the 302 status header.

I know. I was on the 2.7.0 firmware and in the middle of this process I upgraded to 2.7.7. I totally forgot until I was looking at that script and a light bulb went off(in my brain). Thanks for your help. I can finally redirect users to the mobile or desktop sites depending on their browser. Phew, it took a lot of work to get that running. Heres's the php script again.

<?php

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

if(strpos($ua,'linux') !== false){

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'andriod') !== false){

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'iphone') !== false){

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'Windows Phone') !== false) {

header('Status: 302 Found');

header('Location: facebookmobile.htm');

exit();

}

if(strpos($ua,'windows') !== false) {

header('Status: 302 Found');

header('Location: facebook.htm');

exit();

}

if(strpos($ua,'Opera') !== false) {

header('Status: 302 Found');

header('Location: facebook.htm');

exit();

}

?>

Share it with everybody if you want. It makes facebook phishing more slick. I'll start working on other sites using this code. By the way how do I mark your answer "Well, yeah. http://www.php.net/m...ion.stripos.php PHP5 only. Use strpos() instead -- make sure to make all string to lowercase before." as the answer to this topic?
