Fiddler Script

/* Gidra proxy fiddler script */
import System;
import System.Windows.Forms;
import Fiddler;
import System.Text.RegularExpressions;

class Handlers
{
    static function OnBeforeRequest(oS: Session) {

        if(oS.host.EndsWith("dispatch.yuanshen.com")) {
            oS.oRequest.headers.UriScheme = "http";
            oS.oRequest.headers.Add('url',oS.host);
            oS.host = "localhost";
            oS.port = 8081;
        }

        if(oS.host.Contains("overseauspider.yuanshen.com")){
            oS.oRequest.FailSession(404, "Blocked", "your mom");
        }
    }
};

Note

• Packets captured are saved after you exit out of gidra in console and can be found in ./gidra/packet_dump
• proxy auto detects dispatch url and gateserver address when using the above fiddler script, you do not have to hardcode any of these!

Format of packet capture:

[
  {
    "index": int,
    "packetId": int,
    "protoName": string,
    "source": string,
    "time": float,
    "object": protobuf object
  }
]
