arduino based ransomware ?

[Str0ng]

Hello , I wanted to know if it is a good idea to create a ransomware based only on Arduino, that when inserted into a PC, it begins to encrypt the files, but using the Arduino itself, not using a Windows payload

possibly you meant BadUSB? AFAIR attiny85 could be programmed in Arduino IDE and could act as a keyboard.
you will have to guess the target OS and use the corresponding payload anyway, because Arduino itself knows nothing about filesystems and files + operating systems usually do not give filesystem access to USB devices.

if I meant to create a hardware that accesses the file system

I am not sure but I think it is impossible via USB. it is theoretically possible via PCIe but it is not an Arduino level already

使用 ATtiny85，只需模拟键盘并将代码上传到系统，系统就会帮你完成所有工作。
