PwnBerry Pi (https://github.com/g13net/PwnBerryPi) is advertised as another penetration testing suite for Raspberry Pi and is based on Raspberry Pwn as discussed earlier. Much like Raspberry Pwn, Pwnberry Pi has not been recently updated, which seems to indicate that for penetration testing the field is consolidating around Kali Linux.
It should also be noted that best practice is not to use many of the tools required for web-based penetration testing from a lower-end system such as a Raspberry Pi. For example, PwnBerry Pi includes the installation file for Browser Exploitation Framework (BeEF), rather than installing it knowing most penetration testers wouldn't run this application from an ARM image. If you install BeEF on this ARM image, you will see a warning banner added by the PwnBerry Pi development team claiming they experienced erratic behavior when using BeEF from the PwnBerry Pi image.
The installation process of PwnBerry Pi is very similar to the Raspberry...
