Hacker Creates a Proxy Server For Siri To Easily Add New Functionality; Demos Controlling a Wi-Fi Thermostat [Updated]

Siri Icon

Few days back, folks at Applidium had cracked Siri’s security protocol and the format it uses to communicate with Apple’s iPhone 4S.

Using that knowledge, hacker who goes by the Twitter handle plamoni has created a proxy server for Siri – Apple’s revolutionary voice activated personal assistant feature called Siri Proxy. He says that the idea behind the proxy server is to make it easy for developers to add functionality to Siri.

He has released the source code of the proxy server along with the instructions on how to set it up on social coding site – GitHub.

He has also demonstrated how the proxy server works by creating a plugin to control a Wi-Fi thermostat, which responds to command such as “What’s the status of the thermostat?”, or “Set the thermostat to 68 degrees”, or even “What’s the inside temperature?”

You can checkout the impressive video demonstration of using Siri to control the thermostat using the proxy server:

The ability to add functionality to Siri on your own does seem very cool. It will be interesting to see what other fun things we get to see using the Siri proxy.


Pete (Twitter handle plamoni) who has developed the Siri Proxy server has clarified in the comments section that this hack doesn’t need a jailbroken iPhone:

I’m the creator of this particular hack, and I can assure you, it doesn’t require the iPhone to be jailbroken. My iPhone 4S is not jailbroken. The only action I needed to take on my iPhone was to install my fake Root CA. Which you can do without jailbreaking. Everything else is done outside of the phone, so it requires no jailbreaking or code to be placed on the phone itself.

Thanks Pete!

In the FAQ section of the SiriProxy project page on GitHub, he has also answered the question about whether this hack will let you run Siri on my iPhone 4, iPod Touch, iPhone 3G, Microwave, etc.

Short answer: No.

Longer answer: While this doesn’t let you do such a thing, it could HELP with such a thing. For instance, if you get Siri installed on your iPhone 4 (don’t ask me how to do this, I really don’t know), and you get someone to give you a valid iPhone 4S UDID (don’t ask me for mine, I will ignore your request), you could use this proxy in order to substitute the valid UDID for your device’s invalid UDID. It would be pretty trivial. Of course, that would allow anyone with access to the proxy use your UDID, so I’d recommend against that sort of action on anything externally accessible without performing some sort of authentication (might I suggest, checking the phone’s UDID? hehe).

You can checkout Siri Proxy’s GitHub page for more details.

    This is a huge breakthrough, and let’s hope the rest of the development processes are not interrupted by Apple.

    this allows the use of Siri on an iphone 4 also?

    • OGT

      Did you read everything? He said no! If you have a UDID valid you can install it on the 4… Meanwhile….. NO!!!!!

  • Paradox

    WHat I am finding interesting is the fact that all these Siri hacks required the iPhone 4s to be jailbroken….

    Now we have a few different hackers that have been giving us Siri hack info…. which means we have a few iPhone 4s phones out there jailbroken. Are these guys all using something dev team is working on and is in beta? Or are these guys all showing up dev team and hacking the phones themselves…..

    What we need is to hear from Dev team .. seriously .. “we have 5 user land exploits ready for 5.0”

    How about releasing 1 of them……..

    How about an update from dev team. Its been several weeks since we have heard anything from them…. I’m not jumping up and down ranting “untether now!!!” but I think after all the boasting they did about their exploits they at least can give us an update being that all these Siri hackers seem to be doing just fine ……

        interesting .. thank you for the information. I stand corrected at least on this then.

        I am curious, how do you go about getting access to install the fake root CA?

        Please forgive my ignorance on the subject…

    Wont work in the future because Apple will block it.

  • The Dude

    What I heard is that the Dev team has exploits to jailbreak the 4S, but they aren’t legal, and so they can’t release them to the public. However, they have used them to test siri back-end functionality, which is how they’ve also been able to port siri over to the iphone 4 and 3gs. However, the security token to access the server at Apple is from a 4S, so again, they can’t release a method to make that work for the public because it is a private token of another device.

    • Paradox

      I thought userland exploits were legal because they are merely exploiting a bug .. this is different from the siri hack to iPhone 4 which is actually pirating code from iPhone 4s which definitely is illegal.

      jailbreakme.com was a userland exploit if I recall…..

      I could be wrong….

    I don’t know about everyone else but it seems that the Jailbreak Community, Apple and everyone else should start moving Siri’s actions from the phone itself, alleviating servers all together. If this trend is started now, it can only be a positive one.
    First off is Speed. Instead of waiting for you phone to contact a server and bounce back to you only to read you appointments or your contacts is too many extra steps. Skip steps and speed it up.
    Next is reliability. We all know how Apples server shut down for Hours leavIng everyone with an iPhone 4 with a nice camera. Imagine if a hack came out where ALL iPhones could contact Siri?? Siri would crash and nobody could use it. Also, say your in a spot without Internet where you REALLY could use an assistant to help you, Siri is completely useless.
    Lastly(that is on the top of my head) is security. If EVERYTHING you ask gets in the hands of Apple or at least has to transfer to it, then to me it seems like a huge security risk. The more that is done on the phone itself the safer I feel. I know some of you feel this way. It can’t be just me n

  • joe

    will the dev team please give us some idea when the untether is going to come out.iphone 4 on ios 5 needs to be unlocked. at least let people know. thank you. joe. uk.

  • steve jobs jr.

    Dev team sucks now. I need Geo Hotz to help.

    Looks like hackers increased the power of Siri. Will see how this development will continue, but probably apple will patent hackers job and will say they they have copied their technology.

    But would love to control my cars air conditioner with voice! :)

  • nothappyforSIRI

    geeezzzz! im tired of this Siri sh** being exclusive for the iPhone 4S. Why don’t create something
    for jb users instead of trying to hack Siri. lets call it VIKI. lol! just saying.

  • iCiph4EG

    Very cool…! i cant wait for it to be completly finished so all of us without a 4s can enjoy siri too!
