For years now I have been a huge proponent of the Raspberry Pi. I started with a Raspberry Pi 2, which required a USB WiFi dongle for wireless, to a Raspberry Pi 3b with onboard WiFi. Later I would get a pair of Raspberry Pi Zero W’s, and finally, this past summer, the newly released Raspberry Pi4, with 4GB of RAM and 64bit ARM.
Pi’s have always been marketed as a small, affordable, credit card sized, turn key micro computer. Their relatively small size and well supported hardware accessories have made it a great choice for mobile penetration testing, and a host of supported operating systems. Fortunately, Kali Linux is one of those systems, and a great choice for setting up not only a mobile pentesting system, but also one at your desk if you can’t afford a more expensive PC.
The Raspberry Pi4 model I use is the 4GB version. It specs out with:
- Quad Core Cortex-A72 ARM v8 64-bit processor @ 1.5GHz
- 4GB LPDDR4-2400 SDRAM
- 2.4 and 5GHz 802.11ac wireless, and Bluetooth 5.0
- Gigabit Ethernet
- 2 USB 3.0 ports and 2 2.0 ports
- 2x micro-HDMI ports
There are also 1GB and 2GB versions for slightly lesser prices, however there is a world of difference made with that extra RAM, and well worth the extra $20 if you can afford it. Many kits are also available for the Raspberry Pi, with my favorite being from CanaKit, which includes a complete starter kit, with a Pi4, 32GB Micro SD Card, Case and fan, power supply, HDMI cable, and Power cable. This kit runs $99, and can be found here on Amazon. Alternatively, you can also choose to piece together your own kit.
