At the end of June, the Raspberry Pi Foundation engineers officially unveiled the fourth generation of Raspberry Pi single-board computers. Compared to older models, the Raspberry Pi 4 has changed significantly and has acquired several notable innovations at once. The main technical characteristics of the new single-board are:
- 64-bit quad-core Cortex-A72 processor with H.264 and H.265 support and a frequency of 1.5 GHz;
- RAM LPDDR4 SDRAM with a capacity of 1, 2 or 4 GB to choose from;
- two micro HDMI ports with dual monitor and 4K support;
- VideoCore VI GPU with OpenGL ESx support;
- Bluetooth 5.0 support, two USB 3.0 ports (in addition to two USB 2.0) and a USB Type-C port, replacing micro USB;
- high-grade Ethernet 1 Gb / s (USB will no longer be a bottleneck), Wi-Fi with 802.11ac support.
The cost of new items depends on the amount of memory on board. So, the version with 1 GB of RAM costs $ 35, and variations from 2 and 4 GB will cost $ 45 or 55, respectively.
Currently, Kali Linux for Raspberry Pi 4 is only available in the 32-bit version, although Offensive Security promises to release a 64-bit version in the very near future.This concerns only the Raspberry Pi 4, for the models 2 and 3 already exists a 64-Bit-Version.
The 32-bit version of Kali Linux for Pi 4 can be downloaded here , and detailed instructions on how to configure it are available here .
Compact eavesdropping
Among other things, Kali Linux can switch the WLAN hardware to monitor mode on the Raspberry Pi 4 and perform a frame injection attack. In this way, WLAN traffic can be overheard, recorded and manipulated with a compact device without additional hardware. As a desktop environment, the slim Xfce is used, the PC version of Kali Linux, however, sets by default on Gnome.
