Whisker is a cat-themed prototyping & hacking console. This cute tool lets you explore the wireless landscape around you and learn how to audit computers with the help of our free content & educational firmware. Powered by an ESP32, Whisker is equipped for wireless hacking, USB attacks, and many other exploits at an affordable price.

While great for pentesting, Whisker’s extensible platform can also be used to build your next prototype with hundreds of plug-and-play sensors! Or modify it to suit your needs since everything is open source!

Hacking & Prototyping Can Be Cute

With its open firmware, plentiful ports, and easy-to-use interface, Whisker is an affordable tool to learn about all kinds of security and a great way to play around with creating custom hardware:

Wireless Recon

Whisker is ready for your next wireless audit—our wardriving firmware lets you visualize wireless devices & networks around you through interactive maps and is even compatible with popular tools like Kismet and Wireshark when you’re ready to take it to the next level!

Learn about Wi-Fi Hacking through our firmware that lets you spoof Wi-Fi packets, host honeypots, and learn about other useful techniques. The SMA Wi-Fi antenna enables you to adapt to any scenario—whether foxhunting rogue devices or sniffing Wi-Fi from blocks away, Whisker can do it all.

Test USB Attacks

Deploy hundreds of USB Attacks at the press of a button—and debug them in real-time with an on-screen feline friend!

Our ScriptKitty Firmware emulates a USB keyboard to deploy keystroke injection attacks on target devices. Whisker can compromise unattended computers in the blink of an eye, regardless of the operating system! You can even trigger payloads remotely over a Wi-Fi-controlled interface.

Build Hardware Prototypes in Minutes

Prototype your next project or hacking rig with our modular hardware - Whisker is compatible with hundreds of plug-and-play sensors from Adafruit & Sparkfun (using Stemma QT & Qwiic Connect)—and awesome expansion boards coming soon to Crowd Supply!

Our CircuitPython-compatible boards will have you prototyping in minutes. You can even daisy-chain Whisker boards to build the ultimate wireless recon platform and scan multiple targets simultaneously!

Putting the “Cat” in Education

Whisker hopes to empower the next generation of hackers and makers and provides open-source design files, software, and educational resources that let you truly own your hardware. It’s field-tested, too, as we’ve used it successfully to teach workshops at Crowd Supply’s Teardown conference & local hackerspaces! This new version of our board is a redesign of the existing board, with surface mount components and more expansion opportunities!

Whether you’re using it to develop a curriculum for students or seeking to learn by yourself, Whisker can teach anyone new tech tricks.
