当exploit事件发生时，会调用getArgs跟genPayload函数来组合成最后的payload，默认将回显数据发送到编辑框里。

• AntSword
• Behinder
• Godzilla-Base64
• reGerog 其中组件名称为注册的Servlet的名称，可以起一个具有迷惑性的名字来隐藏自己。
  
  

• 获取当前Servlet
• 卸载指定Servlet

数据来源是key师傅的项目：avList

• 自动获取 自动执行系统命令tasklist /svc并分析回显数据。
• 手动获取 手动输入tasklist /svc的结果。

注意上面的表格的单位是错的，应该是byte不是bit
