The RaspyJack Is a Low-Cost Alternative to the Hak5 Shark Jack, Built From a Raspberry Pi Zero 2W
On-board display and joystick make standalone use a little easier, while the bill of materials comes in at half the price of the Shark Jack.
Pseudonymous security researcher "7h30th3r0n3" has designed a pocket-friendly display-equipped alternative to the Hak5 Shark Jack tool, powered by a Raspberry Pi Zero 2 WH single-board computer: the RaspyJack.
"If you need a low-cost alternative to the Hak5 Shark Jack," the maker explains of their creation, "RaspyJack is a Raspberry Pi Zero 2 WH based network multi-tool you can build for around US $40. RaspyJack is an offensive security toolkit intended for cybersecurity professionals, researchers, penetration testers, and ethical hackers."
7h30th3r0n3's RaspyJack was inspired by Hak5's Shark Jack, a compact battery-powered network tool designed to be as unobtrusive as possible. Plug the RJ45 end into a network socket, and an on-board Linux-based operating system can scan a network and individual hosts or execute shell or DuckyScript scripts.
The RaspyJack is a little less subtle, seeing as it is built up from a Raspberry Pi Zero 2W single-board computer, a 1.44" TFT LCD add-on board with joystick and buttons, and a USB-Ethernet adapter for wired network compatibility. On the flip side, that also makes it more usable as a standalone device — providing immediate visual feedback on scan results, without needing to be connected to a phone, laptop, or other display-equipped gadget.
Built for around $42, less than half the price of the Shark Jack, the tool provides the ability to run network and host scans, launch reverse shells, capture credentials through a variety of methods, and provides a file browser for loading text files and images and displaying them on the screen.

For those not put off by the warning, the project's software and bill of materials have been published on GitHub under the permissive MIT license; additional information is available in 7h30th3r0n3's Reddit post.
