 So this is a Ponegachi and much like its name is a play on words of the craze of the 90s the Tomagachi which became very popular the Ponegachi is a simple little raspberry pi w device And it is in a 3d printed case that we have with an eink display So this is just a Raspberry Pi zero eink display being powered off my laptop And it's a pretty clever little device and super cute, which I think is driving its popularity We started playing with this project before the even the website was up when the developer had just had some code on github And you had to do a lot of work to put it together right now as of October 2019 towards the end here. We have full images available. You can just download not leave links to all this below and to the hardware We use raspberry pi zeros make it very low cost So this is a very inexpensive toy to build and the eink display has another advantage of even when you unplug it remembers the eink display and also It's just so stinking cute watching it make all the faces as it learns about Wi-Fi environments And let's talk about what it does a little bit more specifically here So the Ponegachi is doing AI powered better cap and what that means is whenever there's a handshake within Wi-Fi And let's go through and talk a little bit about how that works down here Whenever there's a Wi-Fi handshake between two devices between the device connecting and then the device is connecting to That three-way handshake can be captured now. They are using good security There is a s nonce and then a a nonce that are Created to create this communication and do it securely so the password itself is not exactly passed across and But even though it's not if you capture that handshake that handshake can be tested And if a known password such as a dictionary attack as they call it if there's a way to Reverse engineer that password easily it can be reverse engineered, but you have to have those cap files now better cap Controlled by AI is because well, there's lots of variations in Wi-Fi in a way. It's installed therefore by using the AI tuning system that they have in here it Will go through and learn the environment it's in and think about the best way to do it and constantly improve upon that method Based on where you take it and I see where you take it because the other advantage of being on a Raspberry Pi 0w is it's very portable you can plug in a battery and away you go So now you have an excuse to get out and go for a walk definitely if you want to go capture some files on there and Start taking a look at it now. It does not in case by its name. You thought it did it is not actually Cracking Wi-Fi it does not do that. It just creates the handshake files and the p-cap files on you can do this yourself With just simply capturing the data and then sorting through it It's doing a lot of that work for you by only creating the files you need to capture now for those of you that think of this as some type Of nefarious tool. It's really not What this really comes down to is it's a testing tool It is a tool by which you can test networks and the other side of a lot of security tools is yes The bad actors and the white hats are going to use these same tools the tool set actually doesn't change your Intentions is what changes what happens So if you wanted to go through and you're doing a pen test for a client and you want to say hey I want to just really quickly See if your network has good Wi-Fi passwords I mean you could ask him for it But if you wanted to prove it as in what they refer to him as red team testing This is a handy way to do it that you can put this in your pocket wander through say alright And here's what we found from a pen test by the way, you're not using good passwords We found out it's password one two three because you can simply just reverse it with a hash and go alright You know this is the password for that so it's not that these tools or this is a particularly bad thing But it does kind of gamify it which is actually kind of a neat thing to do here And this is why I talk about gamifying so these are Ponegaches that are also uploading the data and sharing information with each other about who's using them and kind of making it a Fun little sport and you know, this is the scale of the internet. It makes this kind of fun You can take and connect this online and Push things to the cloud and share all of your findings Which is pretty novel it makes it like I said it that much more fun. So how do you get started with one? Well, it's pretty simple first. You're gonna have to get the parts for a Raspberry Pi zero I'll leave the link below where to get those next you flash an image and they have the download the latest Honegachi dot IMG file So there is a file and you can use things like etcher to install it and just flash it to the SD card There is a full manual install Which is what we were doing with it prior to this image being available a little bit harder But of course you get more customization options if you don't want to pre-build image Initial configuration once you go into it you got to get the configuration file set up now What I want to show you now is how we actually get into it and this is pretty simple, but maybe confusing at first And I'm doing this on Linux so bear with me here if you're young Windows there is a methodology as well But we're gonna go here to my network settings And we see USB Ethernet plugged in and this is a feature that once you have this loaded It shows up as a USB Ethernet adapter and then we have it here We're gonna go to IPv4 and I've set my address to be 10 dot 0 dot 0 dot 1 with a net mask of 255 and no gateway Now to actually get into it the Ponegachi is at 10 0 0 2 so now we're gonna open up a terminal And we're gonna SSH Pi at Dot zero so pie at 10 0 0 2 0 and when you go it will log me in now I already have my SSH keys in is why it didn't prompt me for a password But now we can do sudo root by default. There's no root password sudo su root sorry and Here we go if we look here there is the handshake So we're in the root directory and we're gonna go over here to the handshakes In a way you go you can see the networks It's found and it has the pcap file So this is the pcap files that are result of the Ponegachi and where you get the files from pretty straightforward and simple Now also running at port 8080. This is essentially how the system works now You're seeing what's actually on the screen. So it shows a channel AP up time Its names are Scannington and kick to station made six new friends got two new handshakes There's only a couple networks in here and it was running for a while So it's only two new handshakes based on a couple devices I had set up But I think it's kind of cool how you can see this here and if you went to just the root of it There is actually the interface for better cap itself So you can do your own tuning and dive deeper into it now as the Ponegachi works It shows a lot of different faces and there's a lot of detail the creator of this project. It's just an amazing job of Documenting it how things work and linking to even further readings. So you can take in you can really dive deep into this installation configuration Lots of ways to contribute to the project lots of fun And this is not an expensive project to get started so you can start learning right away I think that's one of the important things about Raspberry Pi projects I've seen a lot of in the community is people without access to a lot of high-end hardware I mean you're talking about a project. That's just really inexpensive the Raspberry Pi zero doesn't cost much This whole thing is such a easy way to get started and start learning right away. It's all written in Python It's a hundred percent open source. So you can really play with the code and dive deep into it We've been playing with it for a little while and one of my technicians who started on the project I showed it to him. He just thought it was cute. He likes Tamaki cheese He likes Japan and he says you know This just seems like something fun to play with and it served really as a big learning experience for him He has a better idea now one how to set up Raspberry Pi zeros There is some soldering involved. So that's a whole that was a whole nother little challenge for him To get the little ink device on there the configuring compiling He went through the whole harder way of doing it not just downloading an image and putting it on there But it also was a fun learning experience and then from there you can see whether or not, you know The Wi-Fi passwords we've used here were whether or not they were adequate I would say and there's like I said It's not actually doing anything more than getting the pcat file the Raspberry Pi zero is not strong enough to actually run The hashes against there But boy, this is just a fun project and probably one of the favorite Raspberry Pi projects we've tried I also want to try some more with this ink display because one of the things I'm going to show right now And this is the fun feature of ink is watch this Yeah, all right some plugged. There's no battery or no power ink is There we go focused there we go ink One of the cool things about it is it leaves the last on there It only electrically refreshes things that are on this display It does not actually need power for the display so it stays at the last it's not running anymore There's no battery on this particular model But it will leave the last thing displayed on there, which I think it's kind of funny The other cool thing about it is if you look on the project and we didn't go this week We're just using it here in the office and with a little USB powered battery for a little while they have a whole kit that will put a battery on the back Of it that you can charge up and then make it that much more portable But I'll leave links to all this and you can do some for the reading on it That was kind of the goals to just talk about the projects a few people asking what it is We'd posted about it on Twitter and it's been a fun little toy to play with The short answer is though like I said no it does not actually Reverse engineer any Wi-Fi it just does the cap files in an intelligent way with some AI But boy It's a fun learning project to learn a lot more about one how Wi-Fi works when you dive into that side of it And just put together to create little cute Raspberry Pi project.
