Modify adapter / USB stick for “hidden” connection
When using a BLUETOOTH or CELLULAR or WIFI adapter / USB stick.
Is it then possible to modify the adapter / USB stick so that:
The adapter / USB stick is hidden from Windows?
The adapter / USB stick doesn’t appear in Device Manager in Windows?
The adapter / USB stick gives the computer “hidden” internet connection – while also there is no internet in Windows / in Windows the computer is offline?
The adapter / USB stick gives the computer “hidden” Bluetooth connection – while also there is no Bluetooth connection in Windows?
What level of skill is required?
Only the manufacturer?
Someone trained / skilled?
What would it require?
Some kind of malware on the USB stick?
Change the firmware?
Change the whole USB stick, circuit board etc.?
