Ethical hacking is a fascinating industry that requires a great degree of skill and knowledge. Penetration testing (pen testing) is the art of hacking into a system with the purpose of looking for security concerns. Pulling off this line of work requires specific tools which is where today's Raspberry Pi project comes into play. Maker and developer Pablo Trujillo has created an extremely versatile tool for the job known as Hackbat. It's a custom PCB powered by our favorite microcontroller, the RP2040 which powers the Raspberry Pi Pico W.
This pen testing PCB has a huge selection of tools that make hacking on the go far more pliable. Modules add support for things like using NFC and RF transmission. It's got a microSD card slot for expanding storage, USB support and, of course, has Wi-Fi for tapping into wireless interfaces.
Even in a professional environment, like the cybersecurity industry, you'll find that many of these necessary tools are pricey. Having something open source you can put together yourself not only cuts back on costs but also makes for a modular tool that you can repair or upgrade as needed.
There are off the shelf products for pen testing and general security auditing tasks. Flipper Zero is one of the most prominent, and it too received a recent RP2040 powered add-on in the form of the Video Game Module.
The Hackbat consists of a custom PCB with a Raspberry Pi RP2040 microprocessor controlling the operation. It also features an OLED display panel so you can get real time feedback from the modules as you're using them. A few buttons are provided to navigate menus alongside a PN532 module which provides NFC support while an ESP-12F adds 2.4GHz WiFi.
The Hackbat is totally open source which means you can make your own at home. Trujillo has made the PCB files available for anyone to have printed for free. He used JLCPCB to manufacture the units featured in these images but you can use another supplier if you have one you prefer.

While owning tools such as Hackbat and Flipper Zero is not illegal, they should be used responsibly on your own systems or with permission from clients if you are a professional security consultant.
