使用Peach Fuzzer的模糊TCP数据包

Question

我有两个应用程序，比如Sender.exe和Receiver.exe。我必须对发送方和接收方之间发送的tcp数据包进行模糊处理。

我是Peach Fuzzer的初学者。你能给出一个如何模糊TCP数据包的示例(桃核)吗？我在网上找不到样品。

Answer 1

给定的代码可能会对您有所帮助。此xml PIT代码将向localhost发送一个GET请求，请求标头为

GET https://localhost HTTP/1.1
HOST : http://localhost
content-length: {some value depend ur body}

{body}

只需将此xml放到一个文件中。/peach -1 --debug pathtofile/file.xml
