The team at Applidium has successfully cracked Siri’s security protocol, making it possible to run the voice assistant on the iPad, older iPhone models, and possibly even non-Apple products—including Android devices.
So basically all we had to do was to setup a custom SSL certification authority, add it to our iPhone 4S, and use it to sign our very own certificate for a fake “guzzoni.apple.com”. And it worked : Siri was sending commands to your own HTTPS sever! Seems like someone at Apple missed something!
Siri requires a legitimate iPhone 4S UDID, which can be obtained using the tools that Applidium has published. Be aware that Apple has the power to blacklist identifiers, so don’t distribute yours publicly.
