iPhone Vulnerability Yields Root Access Via SMS
snydeq writes "Pwn2Own winner Charlie Miller has revealed an SMS vulnerability that could provide hackers with root access to the iPhone. Malicious code sent by SMS to run on the phone could include commands to monitor location using GPS, turn on the phone's microphone to eavesdrop on conversations, or make the phone join a DDoS attack or botnet, Miller said. Miller did not provide detailed description of the SMS vulnerability, citing an agreement with Apple, which is working to fix the vulnerability in advance of Black Hat, where Miller plans to discuss the attack in greater detail. 'SMS is a great vector to attack the iPhone,' Miller said, as SMS can send binary code that the iPhone processes without user interaction. Sequences can be sent to the phone as multiple messages that are automatically reassembled, thereby surpassing individual SMS message limits of 140 bytes."
Wondering if this can be combined with iPhone's ability to heat red hot while in your pocket
So this is bad news for the iPhone but it seems like any carrier of the iPhone should want to implement a simple filter to remove any malicious SMSs from the system.
"...Malicious code sent by SMS to run on the phone could include commands to monitor location using GPS, turn on the phone's microphone to eavesdrop on conversations,..."
Cool now my wife can have that iphone she always wanted.
If any of you iPhone users wants to know how to prevent this attack, please reply with your cellphone number and I will TXT you the details.
You're welcome!
Nice little dDos attack device, with one hell of a use fee at the end of the month ...

1) Hacker Sends SMS to target phone
2) Phone gets virus, virus looks up address book and sends itself to everyone in their address book
3) Phone with virus does evil stuff to phone
Damn, that's excellent... erm, I mean... too bad... for... you know... California... and Art Students...
Phones are for phoning people
PDAs/Netbooks/Laptops are for doing business on the move
Laptops/Gameboys are for mobile gaming
The only combination I'll accept are mobile phones that play my MP3's... since it's a small, simple extension of the already availible 'ringing' feature of phones :P
Oh, and cameras... I'll accept camera phones... They're useful.
And Skype access
And Wifi for the Skype...
and while we've got Wifi we might as well have a browser
and maybe the ability to put other apps on it too...
*damnit* I've fallen for feature creep... someone help!
It pays to be obvious, especially if you have a reputation for being subtle.
"as SMS can send binary code that the iPhone processes without user interaction"
Why is it even possible to send raw binary? Shouldn't it allow only a heavily-filtered subset of characters?
it was as if 1000 apple fanbois cried out and then were silent...
If you mod me down, I will become more powerful than you can imagine....
Could the iPhone be jailbroken via SMS?
Who the fuck though it would be a good idea to automatically execute the content of a message you have no control over whatsoever?
He used to work for Microsoft where he spent his time adding "can execute code" to all their media file formats. Now he's at Apple (and continuing the good work...)
No sig today...
That's just great. I can't use all the features of the iPhone because it is crippled by the providers, but any dumbass can get root by SMS?
If I had "bought" one (I consider the current way of getting it as rent-to-own), I would be pissed.
You're not old until regret takes the place of your dreams.
SMS has a limit of 160 characters, not 140. Twitter has a 140-character limit because of its SMS-interface which leaves 20 characters for commands etc. in addition to the message.
from the second link: "We present techniques which allow a researcher to inject SMS messages into iPhone, Android, and Windows Mobile devices."
I don't get your mindset. The phone has obviously sold millions upon millions. It's doing something right. It's called usability and the iPhone has it by the bucket loads. Before the iPhone came about putting apps onto a phone was annoying and awkward for the average user. You had to download the .sis (On symbian OS) then put it on a memory card, then finally install it.
Apple have made mobile applications accessible to the masses, and Grindr is proof of that.
I don't agree with everything Apple has done with the iPhone, but I agree with enough of it to have just ordered a 3Gs.
My previous phone was a Nokia 6600 which was probably more feature rich, but using it was torture.
That would be Steve Jobs ... but he's a sick man.
Yeah, because the same happened in the webserver market. Apache installations get rooted every single minute.
This might be linked to the MobileMe Find My iPhone, Remote Wipe, and remote message facilities. If these are commands sent by SMS message from MobileMe, then perhaps they can be overflowed to run arbitrary commands.
After all, if you can wipe the phone remotely, then that system has root access, does it not?
N.B. I am not a security researcher.
Finally had enough. Come see us over at https://soylentnews.org/
It's not a true SMS-to-root exploit. So far he's only been able to crash part of the device's software with it, he's still looking into whether it can be used to run arbitrary code.
No kidding!!! What do you say at this point?

Pwn Different!
Just Pwn.

And the case of binary data, you're dead wrong.
GSM SMS payload is 140 8-bit characters, or bytes, depending how you look at it.
The default SMS text encoding format uses 7-bits, and employs a bit-shifting algorithm to pack 160 7-bit characters in to 140 bytes. Binary formats can't use this compression, as, well, they need all eight bits.

Nice little bit of paranoia you've got going there.

I recently canceled texting completely on my iPhone 3GS. Texting fees are outrageous and I'm not putting up with them anymore. If you want to text me, send it to my email address. Your phone probably supports texting to an email address and you don't even realize it. You can also reply to free texts I send you and I get notified instantly.
Sure, I can't receive texts sent to my phone number, but that's a sacrifice I'm willing to make if I'm going to help my country kick this ridiculous habit of overpaying for tiny emails.
