bWAPP, or a buggy web application, is a free and open source deliberately insecure web application. It helps security enthusiasts, developers and students to discover and to prevent web vulnerabilities. bWAPP prepares one to conduct successful penetration testing and ethical hacking projects.

What makes bWAPP so unique? Well, it has over 100 web vulnerabilities!
It covers all major known web bugs, including all risks from the OWASP Top 10 project. bWAPP is for web application security-testing and educational purposes only.

Have fun with this free and open source project!
bWAPP is a PHP application that uses a MySQL database. It can be hosted on Linux/Windows with Apache/IIS and MySQL. It can also be installed with WAMP or XAMPP. Another possibility is to download the bee-box, a custom Linux VM pre-installed with bWAPP.

First of all you have need to install a local server over system that may be XAMPP, WAMP or LAMP. These servers are totally free of cost you can freely download from the internet. Mostly XAMPP is used because it has more functionalities than others on the other hand WAMP is also a simple platform for PHP while, LAMP is used over the Linux distributions. After downloading any one of them you have need to install that first after that you'll be able to configure bWAPP over your system.

Why we use the software application for configuring this bWAPP? As we know PHP is a server side language and there must be a server to read the PHP script. Without using any server we can't do programming with PHP. If you have a little piece of code of PHP you must install a server in your system for running that PHP script.

I have read a blog post, where you can build your own privacy proxy server built on Raspberry PI. The post got me thinking about how I can use this to protect my privacy on my Android phone, and also get rid of those annoying ads.

Since I own a Samsung Galaxy S3 LTE with Android 4.3 (with a HW based Knox counter), rooting the phone now means you break Knox, and loose warranty. Past the point of no return ...

This means I have to solve this without root. Luckily newer Androids support VPN without rooting, but setting a mandatory system-wide proxy is still not possible without root.

But thanks to some iptables magic and Privoxy, this is not a problem anymore :)

The ingredients to build your own privacy protection proxy:

One (or more) cheap VPS server(s)
a decent VPN program
Privoxy
iptables

VPS server

To get the cheap VPS server, I recommend using Amazon EC2, but choose whatever you like. The micro instance is very cheap (or even free), and has totally enough resources for this task. I'm using the Ubuntu free tier now and it works like a charm. And last but not least Amazon has two-factor authentication! You can set up an Ubuntu server under 10 minutes. Use the AWS region nearest to you, e.g. I choose EU - Ireland.

VPN

For the VPN program, I recommend the free version of the OpenVPN AS (EDIT: be sure to use OpenVPN AS 2.0.6 or later, both on the server and the client). Easy to set-up quick start guide is here, GUI based configuration, and one-click client installer for Android, iOS, Windows, Linux, OSX. The Ubuntu installer packages are here.

The most important settings:

I prefer to use the TCP 443 and UDP 53 ports for my OpenVPN setup, and let the user guess why.
For good performance, UDP is preferred over TCP.
VPN mode is Layer 3 (routing/NAT).
Don't forget to allow the configured VPN ports in the AWS firewall (security groups).

Other VPN settings:

Should VPN clients have access to private subnets (non-public networks on the server side)? - Yes
Should client Internet traffic be routed through the VPN? - Yes

Privoxy

The next component we have to install and configure is Privoxy. As usual, "apt-get install privoxy" just works. The next step is to configure privoxy via /etc/privoxy/config file, there are two options to change:

listen-address your.ip.add.ress:8118
accept-intercepted-requests 1

Beware not to allow everyone accessing your Privoxy server in the AWS EC2 security groups, be sure it is reachable only to VPN users!

After everything is set, start privoxy with "service privoxy start", and add it to the autostart "update-rc.d privoxy defaults".

Iptables

And the final step is to configure your iptables chain to forward every web traffic from the VPN clients to the Privoxy server:

iptables -t nat -A PREROUTING -s 5.5.0.0/16 -p tcp -m multiport --dports 80,8080,81 -j DNAT --to-destination your.ip.add.ress:8118

Optionally you can block access to all other ports as well, and what does not go through your Privoxy won't be reachable.

Based on your Linux distribution and preference, you might make this rule persistent.

Final test

Now you can connect to the VPN server from your Android device.

After logging in from a client, you get the following nice packages to install on your device:

After connecting, the final results can be seen in the following screenshots. And yes, there is a reason I chose Angry Birds as an example.

Angry Birds without Privoxy

Angry Birds with Privoxy

Spoiler alert

If you are afraid of NSA tracking you, this post is not for you. If you want to achieve IP layer anonymity, this post is not for you. As long as you are the only one using that service, it should be trivial to see what could possibly go wrong with that.

Known issues

Whenever the Internet connection (Wifi, 3G) drops, the VPN connection drops as well, and your privacy is gone ...

Sites breaking your privacy through SSL can still do that as long as the domain is not in the Privoxy blacklist.

Additional recommendation

If you are using OSX or Windows, I can recommend Aviator to be used as your default browser. It is just great, give it a try!

PS: There are also some adblock apps removed from the official store which can block some ads, but you have to configure a proxy for every WiFi connection you use, and it is not working over 3G.

Top 10 Best Operating System Professional Hackers Use

Top 15 Best Operating System Professional Hackers Use

A hacker is someone who seeks and exploits the weaknesses of a computer system or network computing. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge, enjoyment or to assess these weaknesses to help in removing them.
