William Knowles published this great project on his blog.
The PiTap is a device I put together with the intention of being a pentesting tool, but it has also found utility in facilitating data collection as part of my Industrial Control System (ICS) security research. I need to do a lot of packet captures; often at multiple points within a network. This can be quite a time consuming process to set up and configure, so I set out to put together what I like to call a “plug-and-capture” device.
- Small and portable.
- The bridge and packet capture would start automatically on boot.
- It didn’t need to run on mains power.
- Minimal hardware configuration allowing the SD card to be cloned and run on multiple stock devices.
- Raspberry Pi.
- USB power supply. I used the battery from my Wifi Pineapple MK4 battery; however, I have had success in running it from a cheaper Duracell USB battery (5V 0.6A).
- USB Ethernet adapter (the Pi only has one Ethernet port).
