How to Hack a Router with RouterSploit on the Raspberry Pi

A majority of people do no update their routers or other IOT (Internet of Things) devices on their network, this is where RouterSploit comes in. RouterSploit will search a device for multiple known exploits and vulnerability and if any are given will give you access to these devices. RouterSploit will also check these device credentials and attempt to find if the device is using the default username and password. Updating your device firmware and changing passwords are the easiest and best way to protect your system from hackers, yet many people do not do these steps. also many older IOT devices like IP Cameras or printers might not even be supported anymore and these devices may have vulnerabilities that will never be patched and can compromise your whole network.

RouterSploit is a python script which will scan devices for multiple exploits and vulnerabilities and mainly focuses on embedded devices like IP cameras, routers and printers. You just need to set the target IP address and run the script and RouterSploit will do the rest. You can only check devices that are on your network, meaning you need to be connected to the same network as the device you are trying to hack. You can scan many routers, printers, IP cameras and any other devices that are on your network.

Using the Raspberry Pi to run RouterSploit makes it easy to check networks on the go. You can bring your Raspberry Pi over your friends house and connect into their network and check their network for any vulnerabilities. The Raspberry Pi is so cheap and easy to work with which makes it a great pen-testing tool to have. I will show you how to install RouterSploit on the Raspberry Pi and how to use the basic features of RouterSploit.

Objective

To install RouterSploit on the Raspberry Pi

Material

You will need the following:

Instructions

We’ll be installing the latest version of RouterSploit, which at the time of writing this article was 3.3. I will assume you are connecting to your Raspberry Pi over SSH. If you are working directly on the Raspberry Pi simply open up a terminal window and run the commands from there. I tested this using a Raspberry Pi 3 running Stretch but this should work for older versions as well. I also had the GUI running on my Raspberry Pi which may include some packages pre-installed. For example the lite version of Stretch will not have ‘git‘ installed and you will have to install ‘git‘ before running the ‘git‘ command. Continue Reading

How to Create a Simple Python Chatbot on the Raspberry Pi

I have recently been working on a new project that required scraping data from other websites and have been slowly learning python. I usually work with PHP but I knew python will work faster and better. I also have always wanted to create a simple chatbot that I can input text into and it would reply with something meaningful. Creating a chatbot with a huge database of words and actually understanding what is being said is not an easy task and is something that is way over my head. I was browsing Reddit and found out that you can get results in JSON format is you append ‘.json‘ to the end of the URL. This got me thinking, what if I search Reddit with a question or comment and pick a random search result and reply with one of the top comments. This would fill my urge in creating a chatbot and it would also be a good starting point if I ever wanted to go deeper into creating a database and store answers for the chatbot to get a personality of its own.

I figured the Raspberry Pi would be an easy starting point since I have a bunch of them laying around and it is already setup with a Python environment. You can easily replicate this in any Python environment but I tested out my chatbot on the Raspberry Pi.

Objective

To create a chatbot in Python on the Raspberry Pi that searches Reddit and replies using a Reddit comment

Material

You will need the following:

Google FooBar – Level 2 – Lovely Lucky LAMBs – Python

I’ve recently been learning Python and was invited to the Google Foobar challenge. Google Foobar is an invitation only event that appears if Google detects that you’ve been searching for Python or Java related topics. You can accept the even and complete 5 levels which if you complete you will be able to fill out your personal information for a chance at an interview at Google. My skills aren’t the best but I had some trouble figuring out some of the levels so I decided to publish my submissions in hopefully helping someone out. This level was especially difficult since I didnt quite understand the approach to it and had to figure out the Fibonacci Sequence.

Objective

To complete the Google Foobar Level 2 challenge, Lovely Lucky Lambs

Instructions

This puzzle was a little tricky. I figured out the way to get the first half by doubling the values. The second part of the puzzle requires the knowledge of the Fibonacci Sequence and without knowing the Fibonacci Sequence and numbers you would be lost in this level.  You’ll notice that up on top of my code I return the number 8 as one of the answers if the total lambs is equal to 917503. This is the answer for ‘Test 9’ of the 10 tests that Google runs your code through. My code will not output the correct answer for Test 9 so I had to brute-force the answer. My code should work for this level to pass all 10 tests. Continue Reading

How to install Doom on the Raspberry Pi 3

Doom is a classic DOS game and has been ported to many operating systems and now you can play it on your Raspberry Pi in just a few minutes. You can even setup a joystick or controller to play Doom and relive your childhood memories. You can also download a ton of WAD’s (“Wheres all the Data”) for Doom. WAD’s are like old school mods and include new levels, weapons and really just transform your Doom playing experience. There are many WAD’s out there right now which make the game completely different.

We’ll be using the Chocolate Doom port today to install and play Doom. Chocolate Doom try’s to mimic the original experience of Doom as much as possible. Chocolate Doom’s main features are its accurate reproduction of the game as it was played in the 1990s. We’ll be downloading the source for Chocolate Doom and building and compiling the code on the Raspberry Pi, so this may be a new experience for some people but I promise it is very easy to do.

Objective

To install and play Doom on the Raspberry Pi 3

Material

You will need the following:

Instructions

We’ll be installing the latest version of Chocolate Doom, which as of this tutorial is 3.0.0. You can check to see if there are new version’s by clicking here. You would just need to modify the ‘wget‘ commands and directory commands below to match the version and file names that you downloaded. Continue Reading

Google FooBar – Level 1 – Braille Translation – Python

I’ve recently been learning Python and was invited to the Google Foobar challenge. Google Foobar is an invitation only event that appears if Google detects that you’ve been searching for Python or Java related topics. You can accept the even and complete 5 levels which if you complete you will be able to fill out your personal information for a chance at an interview at Google. My skills aren’t the best but I had some trouble figuring out some of the levels so I decided to publish my submissions in hopefully helping someone out.

Objective

To complete the Google Foobar Level 1 challenge, Braille Translation

Instructions

This level should be straight forward. You will simply need to create a Braille lookup tables list or array and translate the words given to you in Braille. You will need to interpret if the letter is capital as well as spaces. Below is the Google Foobar challenge. I ended up looking up what the Braille Charchets should be from the Braille Wikipedia page. If you notice from the Braille page it shows the Braille dots for the letters A to Z but they do not match the pattern Google wants you use so I had to manually create a list in the correct binary order.

How to Check your PiVPN logs on your Raspberry Pi

If you are running your PiVPN on your Raspberry Pi it is most likely exposed to the internet so that you can use your VPN away from your house. You will definitely want to make sure your Raspberry Pi is up to date with the latest security updates as well as checking your logs periodically to see if anyone has attempted to gain access to your system or worse, to see if anyone has accessed your system.

Objective

To use VNC to access our Raspberry Pi Remotely

Material

You will need the following:

Instructions

I will assume you are running Raspbian on your Raspberry Pi and have already installed PiVPN using the tutorial here. You are most likely running your Raspberry Pi headless if this is your PiVPN server so you will need to SSH into your Raspberry Pi. If you are not running your Raspberry Pi headless you can still run the same commands below in your terminal. Continue Reading
