小编给大家分享一下AutoGadgetFS是一款什么工具，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
关于AutoGadgetFS
AutoGadgetFS是一款开源框架，它可以帮助广大研究人员在无需深入了解USB协议的情况下对USB设备以及相关的主机/驱动器/软件进行评估。该工具基于Python 3开发，并且使用了RabbitMQ和WiFi访问来帮助研究人员对远程USB设备进行安全审计。在ConfigFS的帮助下，AutoGadgetFS允许用户迅速克隆和模拟设备而无需深入研究每一个实现细节。除此之外，该框架还允许用户创建自己的模糊测试器。
功能介绍
轻松查找、选择并连接到USB设备。
模拟任何USB HID设备。
以中间件设备身份执行AGFS嗅探HID设备（将通信保存到磁盘）。
设备嗅探（任何设备）。
多个Fuzzer允许您对设备或主机进行模糊测试。
随机Fuzzer（具有固定或随机长度的数据包）。
智能Fuzzer，可以从以前的USB通信中学习。
可以告诉Fuzzer哪些字节要模糊化，使包的其余部分保持不变。
小工具Fuzzer。
顺序Fuzzer。
控制传输枚举器。
从文件中重放数据包。
从保存的USBLyzer捕获重放数据包。
显示数据包的可视方式，以便于对通信信息进行逆向分析。
DFU模式下的设备警报，或者设备泄漏信息。
支持对USB设备和主机进行远程调试。
监控突然的界面变化。
