USBSamurai — A Remotely Controlled Malicious USB HID Injecting Cable for less than 10$
TL;DR: The Video is self-explanatory. (Wanna know how to make it? Read the article below.)
All started with this Tweet last April, when I wanted a damn cheap USB implant capable of injecting keystrokes.
It had to be:
- Remotely Controllable
- Fast in Typing
- Tiny as f***k
- Cheaper than a bottle of Vodka
The main idea (for the hardware-side) is to re-use the Logitech’s inexpensive Unifying dongles as implants within USB cables.
To give you an idea… this is how much this dongle cost (CU-0007): 7.74 EURO!
What you need to do is DEAD SIMPLE:
- Remove the top black case without breaking the dongle;
- PULL out the PCB & the orange plastic holder [gently hold the metal case with a vice (use gum for projecting it) then with a pair of pliers gently but firmly pull out the stuff];
- Pop-open an USB Cable (I do suggest either [1] or [2]) and solder the Vcc& GND to their related pins on the CU-0007.
- Once everything will be in place, mount back the metal case of the USB male connector.
- Then check if it fits the USB case and glue it with a drop of super-glue.
DONE. Congrats! You just created your First USBsamurai!
Now you just need to pair it with @mame82’s LOGITacker v.0.1.3-beta and you are ready to pwn targets!
Remember to first unpair all pre-paired devices: with the command munifying unpairall
G700 firmware is limited to one paired device per time!
For the Software-side, the good @mame82 came to help with his majestic LOGITacker framework!
So far it supports 4 different NRF-based boards:
- Nordic nRF52840 Dongle
- MakerDiary MDK Dongle
- MakerDiary MDK
- April Brother nRF52840 Dongle
I personally opted for the 4th one [3] since is the only one with external Antenna (i.e. Longer Range).

Just follow LOGITacker’s readme and install the v.0.1.3-beta and install https://github.com/mame82/LOGITacker/releases/download/v0.1.3-beta/logitacker_aprdongle.uf2
I recorder a video to explain how to easily pair USBsamurai with LOGITacker.
Enjoy :)
