Penetration testing is something of a dark art. While commercial tools exist from companies like Core Security and Immunity, most professionals still roll their own tools, often using a combination of proprietary and open source tools. In May, the folks over at Pwnie Express made that a lot easier, releasing Raspberry Pwn, an open source tool that lets enthusiasts turn their Raspberry Pi into a penetration testing and audit tool. Their software, released under the GNU public license, was built on DEBIAN and compiles a small arsenal of common pen testing tools including netcat, wireshark, kismet, cryptcat and others. Bluetooth and wireless connectivity mean the device can be remotely controlled once deployed on a target network.
