    Multi-Protocol Proxy Over TCP & UDP

    Many years ago I programed a console based multi protocol proxy (the sha0proxy) lately I created in dotnet a graphical verison of the tool, but due to the form referesh speed finally I implemented it in C++ with Qt.

    This tool useful for reversing, exploiting & pentesting was finally called rproxy, and its a multi-protocol proxy over TCP or UDP.





    Being in the middle of the communication you can view and modify the bytes before being sent to the client or server.

    In the tools tab right now its possible to open the blob on radare2 for further reversing of the data structures or code.


    A basic mutation based fuzzer is implemented for bug-hunting, just set the % ratio of mutation and the bytes will be modified during specific communications phase.

    One of the powerful things of this tool is the scripting, it is possible to automate a modification in specific moment of the traffic flow.



    For example a script with a single line: "IN 3 20 3F" will write a 0x3f on the offset 20 only on the third packet received from the server. I have used this feature for triggering vulnerabilities.

    Regarding the saving and loading data from disk, it's possible to save and load data in raw and hex formats. Also can be configured for save all the communications or only specific emission.
