I’m firmly within the camp that studying about hacking and, by extension, computer systems typically needs to be enjoyable. Much of the fashionable world purposefully makes an attempt to obfuscate how this stuff work, functionally turning know-how into a large bummer. And if you’d like to be taught extra about networking and Wi-Fi, it may be onerous to know the place to begin.
What if know-how was enjoyable once more? What if it was inviting? What if it had a little kitty cat on it? Enter the HakCat WiFi Nugget.
What is it?
Like the DSTIKE Deauther watch, the WiFi Nugget is an open-source instrument that tries to make the method of studying hacking enjoyable and approachable. Designed by Hak5 hosts Kody Kinzie and Alex Lynd, the system has a tiny OLED display, some buttons, and the face of a cute cat (in honor of a real cat called Nugget) — including up to a very approachable approach to get into Wi-FI hacking. It’s cute and alluring, similar to the Pwnagotchi and the Flipper Zero, which additionally apply the Tamagotchi aesthetic to a enjoyable instrument.
HakCat supplies pre-soldered and pre-flashed nuggets on its web store, however the design is easy sufficient which you can construct it your self from components in case you’re so inclined. Just take the Gerber and BOM (Bill of Materials) recordsdata from GitHub to your native PCB Manufacturer (PCBWay, OSH Park, and JLCPCB, to title a few) and get a handful of them produced. After that, you simply want to order some components from the web, do a teensy bit of soldering, 3D print some cases, flash the firmware with ESPTool in Chrome, and you’re good to go!
What can it do?
Essentially, it might trigger bother with Wi-Fi networks — sending out particular instructions that play with the best way networks and consumer units authenticate one another. In that approach, the Nugget shares a lot in frequent with the DSTIKE watch and might even run a modified version of the identical Deauther instrument by Spacehuhn — however that’s not the one assault you’ll be able to strive. There’s additionally the probe attack, which performs with the preliminary call-and-response instructions, or the beacon attack that allows you to spoof an entry level. Once you’ve mastered these, the parents at HakCat have constructed on Spacehuhn’s unique challenge to create a tool for detecting Wi-Fi Attacks.
The WiFi Nugget is not the one instrument the fantastic people at HakCat have developed. On high of that, there is the USB Nugget, a equally formed instrument that permits you to ship DuckyScript payloads and extra. This device is based mostly on the ESP32S2, and in case you are conversant in the USB Rubber Ducky, you could already be conversant in what you are able to do with it.
How a lot of a menace is it?
Like the DSTIKE watch, the WiFi Nugget is based mostly on an ESP8266 microcontroller, making it a enjoyable, inexpensive instrument for studying the ins and outs of Wi-Fi hacking. It is not, nonetheless, notably highly effective, which is fantastic! The ESP8266 solely has 2.4GHz Wi-Fi, and many more moderen routers have features that protect against deauth attacks (assuming they’re enabled). But just like the DSTIKE watch, you’ll be able to undoubtedly trigger some havoc, notably to older networks and units.
Still, the objective of the WiFi Nugget is not to create a highly effective, all-encompassing instrument just like the Flipper or the Pwnagotchi. It’s higher to consider the Nugget as a enjoyable little buddy that matches on a bag or keychain. It’s actually simply a instrument for studying how to spoof Wi-Fi entry factors, find out about deauth assaults, and discover the chances of what easy microcontrollers can do. And it seems to be cute, to boot.
Could I take advantage of it myself?
Absolutely. Like the DSTIKE watch, the WiFi Nugget is very intuitive and pleasant for brand new customers. It prices lower than $100, and in case you don’t just like the firmware it’s operating, flashing a new binary is straightforward with the ESPTool net interface. It additionally is a kitty cat, which you gotta admit is a large promoting level.
