Ever since I bought my first Android device, I wanted to use the device for WEP cracking. Not because I need it, but I want it :) After some googling, I read that you can't use your WiFi chipset for packet injection, and I forgot the whole topic.

After a while, I read about hacking on tablets (this was around a year ago), and my first opinion was:

"This is stupid, lame, and the usage of that can be very limited".

After playing one day with it, my opinion just changed:

"This is stupid, lame, the usage is limited, but when it works, it is really funny :-)"

At the beginning I looked at the Pwn Pad as a device that can replace a pentest workstation, working at the attacker side. Boy was I wrong. Pwn Pad should be used as a pentest device deployed at the victim's side!

You have the following options:

You have 1095 USD + VAT + shipping to buy this Pwn Pad
You have around 200 USD to buy an old Nexus 7 tablet, a USB OTG cable, a USB WiFi dongle (e.g. TP-Link Wireless TL-WN722N USB adapter works).

In my example, I bought a used, old 2012 Nexus WiFi. Originally I bought this to play with different custom Android ROMs, and play with rooted applications. After a while, I found this Pwn Pad hype again and gave it a shot.

The Pwn Pad community edition has an easy-to-use installer, with a proper installation description. Don't forget to backup everything from your tablet before installing Pwn Pad on it!

I don't want to repeat the install guide, it is as easy as ABC. I booted a Ubuntu Live CD, installed adb and fastboot, and it was ready-to-roll. I have not measured the time, but the whole process was around 20 minutes.

The internal WiFi chipset can be used to sniff traffic or even ARP poisoning for active MiTM. But in my case, I was not able to use the internal chipset for packet injection, which means you can't use it for WEP cracking, WPA disauth, etc. This is where the external USB WiFi comes handy. And this is why we need the Pwn Pad Android ROM, and can't use an average ROM.

There are two things where Pwn Pad really rocks. The first one is the integrated drivers for the external WiFi with monitor mode and packet injection capabilities. The second cool thing is the chroot wrapper around the Linux hacking tools. Every hacking tool has a start icon, so it feels like it is a native Android application, although it is running in a chroot Kali environment.

Wifite

The first recommended app is Wifite. Think of it as a wrapper around the aircrack - airmon - airodump suite. My biggest problem with WEP cracking was that I had to remember a bunch of commands, or have the WEP cracking manual with me every time I have to crack it. It was overcomplicated. But thanks to Wifite, that is past.

In order to crack a WEP key, you have to:

Start the Wifite app
Choose your adapter (the USB WiFi)
Choose the target network (wep_lan in the next example)
Wait for a minute
PROFIT!

SSH reverse shell

This is one of the key functionalities of the Pwn Pad. You deploy the tablet at the Victim side, and let the tablet connect to your server via (tunneled) SSH.

The basic concept of the reverse shells are that an SSH tunnel is established between the Pwn Pad tablet (client) and your external SSH server (either directly or encapsulated in other tunneling protocol), and remote port forward is set up, which means on your SSH server you connect to a localport which is forwarded to the Pwn Pad and handled by the Pwn Pad SSH server.

I believe the best option would be to use the reverse shell over 3G, and let the tablet connect to the victim network through Ethernet or WiFi. But your preference might vary. The steps for reverse shells are again well documented in the documentation, except that by default you also have to start the SSH server on the Pwn Pad. It is not hard, there is an app for that ;-) On your external SSH server you might need to install stunnel and ptunnel if you are not using Kali. The following output shows what you can see on your external SSH server after successful reverse shell.

root@myserver:/home/ubuntu# ssh -p 3333 pwnie@localhost The authenticity of host '[localhost]:3333 ([127.0.0.1]:3333)' can't be established. ECDSA key fingerprint is 14:d4:67:04:90:30:18:a4:7a:f6:82:04:e0:3c:c6:dc. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[localhost]:3333' (ECDSA) to the list of known hosts. pwnie@localhost's password:   _____      ___  _ ___ ___   _____  _____ ___ ___ ___ ___  | _ \ \    / / \| |_ _| __| | __\ \/ / _ \ _ \ __/ __/ __|  |  _/\ \/\/ /| .` || || _|  | _| >  <|  _/   / _|\__ \__ \  |_|   \_/\_/ |_|\_|___|___| |___/_/\_\_| |_|_\___|___/___/   Release Version: 1.5.5  Release Date: 2014-01-30  Copyright 2014 Pwnie Express.

Now you have a shell on a machine that is connected to the victim network. Sweet :) Now Metasploit really makes sense on the tablet, and all other command-line tools.

EvilAP and DSniff

Start EvilAP (it is again a wrapper around airobase), choose interface (for me the Internal Nexus Wifi worked), enter an SSID (e.g freewifi), enter channel, choose whether force all clients to connect to you or just those who really want to connect to you, and start.

The next step is to start DSniff, choose interface at0, and wait :) In this example, I used a popular Hungarian webmail, which has a checkbox option for "secure" login (with default off). There are sooo many problems with this approach, e.g. you can't check the certificate before connecting, and the login page is delivered over HTTP, so one can disable the secure login checkbox seamlessly in the background, etc. In this case, I left the "secure" option on default off.

In the next tutorial, I'm going to show my next favorite app, DSploit ;)

Lessons learned

Hacking has been never so easy before
In a home environment, only use WPA2 PSK
Choose a long, nondictionary passphrase as the password for WPA2
Don't share your WiFi passwords with people you don't trust, or change it when they don't need it anymore
Don't let your client device auto-connect to WiFi stations, even if the SSID looks familiar

I believe during an engagement a Pwn Plug has better "physical cloaking" possibilities, but playing with the Pwn Pad Community Edition really gave me fun moments.

And last but not least I would like to thank to the Pwn Pad developers for releasing the Community Edition!

The OWASP Foundation has selected the technical writer for Google Season of Docs by Fabio Cerullo

The OWASP Foundation has been accepted as the organization for the Google Seasons of Docs, a project whose goals are to give technical writers an opportunity to gain experience in contributing to open source projects and to give open-source projects an opportunity to engage the technical writing community.

During the program, technical writers spend a few months working closely with an open-source community. They bring their technical writing expertise to the project's documentation, and at the same time learn about open source and new technologies.

The open-source projects work with the technical writers to improve the project's documentation and processes. Together they may choose to build a new documentation set, or redesign the existing docs, or improve and document the open-source community's contribution procedures and onboarding experience. Together, we raise public awareness of open source docs, of technical writing, and of how we can work together to the benefit of the global open source community.

After a careful review and selection process, the OWASP Foundation has picked the primary technical writer who will work along the OWASP ZAP Team for the next 3 months to create the API documentation of this flagship project.

Congratulations to Nirojan Selvanathan!

Please refer to the linked document where you could look at the deliverables and work execution plan.

Many years ago I programed a console based multi protocol proxy (the sha0proxy) lately I created in dotnet a graphical verison of the tool, but due to the form referesh speed finally I implemented it in C++ with Qt.

This tool useful for reversing, exploiting & pentesting was finally called rproxy, and its a multi-protocol proxy over TCP or UDP.

Being in the middle of the communication you can view and modify the bytes before being sent to the client or server.

In the tools tab right now its possible to open the blob on radare2 for further reversing of the data structures or code.

A basic mutation based fuzzer is implemented for bug-hunting, just set the % ratio of mutation and the bytes will be modified during specific communications phase.

One of the powerful things of this tool is the scripting, it is possible to automate a modification in specific moment of the traffic flow.

For example a script with a single line: "IN 3 20 3F" will write a 0x3f on the offset 20 only on the third packet received from the server. I have used this feature for triggering vulnerabilities.

Regarding the saving and loading data from disk, it's possible to save and load data in raw and hex formats. Also can be configured for save all the communications or only specific emission.

A WordPress plugin with over one million installs has been found to contain a critical vulnerability that could result in the execution of arbitrary code on compromised websites.

The plugin in question is Essential Addons for Elementor, which provides WordPress site owners with a library of over 80 elements and extensions to help design and customize pages and posts.

"This vulnerability allows any user, regardless of their authentication or authorization status, to perform a local file inclusion attack," Patchstack said in a report. "This attack can be used to include local files on the filesystem of the website, such as /etc/passwd. This can also be used to perform RCE by including a file with malicious PHP code that normally cannot be executed."

That said, the vulnerability only exists if widgets like dynamic gallery and product gallery are used, which utilize the vulnerable function, resulting in local file inclusion – an attack technique in which a web application is tricked into exposing or running arbitrary files on the webserver.

The flaw impacts all versions of the addon from 5.0.4 and below, and credited with discovering the vulnerability is researcher Wai Yan Myo Thet. Following responsible disclosure, the security hole was finally plugged in version 5.0.5 released on January 28 "after several insufficient patches."

The development comes weeks after it emerged that unidentified actors tampered with dozens of WordPress themes and plugins hosted on a developer's website to inject a backdoor with the goal of infecting further sites.
