## Tools

* [FSecureLABS/GWTMap](https://github.com/FSecureLABS/GWTMap)
* [GDSSecurity/GWT-Penetration-Testing-Toolset](https://github.com/GDSSecurity/GWT-Penetration-Testing-Toolset)


## Enumerate

* Enumerate the methods of a remote application via it's bootstrap file and create a local backup of the code (selects permutation at random):
    ```ps1
    ./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --backup
    ```
* Enumerate the methods of a remote application via a specific code permutation
    ```ps1
    ./gwtmap.py -u http://10.10.10.10/olympian/C39AB19B83398A76A21E0CD04EC9B14C.cache.js
    ```
* Enumerate the methods whilst routing traffic through an HTTP proxy:
    ```ps1
    ./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --backup -p http://127.0.0.1:8080
    ```
* Enumerate the methods of a local copy (a file) of any given permutation:
    ```ps1
    ./gwtmap.py -F test_data/olympian/C39AB19B83398A76A21E0CD04EC9B14C.cache.js
    ```
* Filter output to a specific service or method: 
    ```ps1
    ./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter AuthenticationService.login
    ```
* Generate RPC payloads for all methods of the filtered service, with coloured output
    ```ps1
    ./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter AuthenticationService --rpc --color
    ```
* Automatically test (probe) the generate RPC request for the filtered service method
    ```ps1
    ./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter AuthenticationService.login --rpc --probe
    ./gwtmap.py -u http://10.10.10.10/olympian/olympian.nocache.js --filter TestService.testDetails --rpc --probe
    ```
